Re: Just wondering... (form actions; javascript:?)

Well, you can:

<form action='' method='post' onsubmit='sendRequest(); return false;'>

Keep in mind that you need to write the function yourself: retrieve all variables from the form and send them along with the AJAX request.

Also you will have to notify the user that the form is submitted by hiding the form and showing a message, else they might spam click the submit button.

Re: IFrame auto resize in safari

Well, you call the function calcHeight, however in your javascript code, the function is called calcheight , (notice the caption). Also your function just retrieves the height? I assume you have some code that sets the height of the iframe that you have not posted.

Re: Drag and drop in javascript - function query

Well, you added an event listener, that is triggered with the event. The event listener (= function) than does something. For example in the code you provided:

The rectangle is clicked ->
The function myDown is called ->
myDown repositions the rectangle to the center of the mouse and allows the rectangle to be dragged. Then it adds a event listener to the mouse movement (myMove) ->
Then the myMove moves the rectangle along with the mouse ->
If the mouse is up, the function myUp is called
myUp removes the mouse movement eventlistener (myMove) from the mouse movement event and stop the rectangle from being dragged

Re: Drag and drop in javascript - function query

The event argument is automatically passed on with the function, alternatively you can use:

canvas.onmousedown = function(e) {
 return myDown(e);
}

I am not yet familiar with the HTML 5 javascript methods, but it appears as if the init() function formats the canvas into a moveable object, and then redraws it every 10ms. If the user presses on the moveable object, the dragok variable is true and the canvas is moved as long as the mouse is down, which turns the dragok variable false.

Re: Riddles

Situation 1:
The three men pay 30 pounds
(Status: 30 pounds manager/porter, 0 pounds men)

Situation 2:
The porter/manager gives back 3 pounds and keeps 2 pounds
(Status: 27 pounds manager/porter, 3 pounds men)

So you can not add up 27 + 2, as the 2 pounds are already added to the 25 pounds of the porter/manager, which brings them to a total of 27 pounds. And the men only received 3 pounds.

Edit, a better answer:

Let's say the men start off with 30 pounds and the hotel with 0 pounds:
The men have 3 pounds left
The men paid 27 pounds
The manager/porter has 2 (which the porter has in his pocket) + 25 (that the manager has) = 27 pounds
THe manager paid -27 (so he gained)

So you can't add up what the men paid with what the porter has in his pocket (which equals 29), as what the men paid is equal to what the manager and the porter have.

This is really confusing to explain ;)

Re: How do I make a Javascript to change a text from one font to another?

The error is triggered due to the fact that the app.document does not have a child element "body" which is in XHTML the <body> tag. Try the following:

Element.style.fontFamily

If that also triggers an error, you need to give me a bit more information about app.document and its content

EDIT: I dont know, what is "activeDocument"?

EDIT2: In one of my first posts, I posted a function named FontChange() that uses the document element (which is the active document aka the document in which the javascript code is placed/executed):

function FontChange() {

 /* Retrieving font: */
 var FontFamily = document.body.style.fontFamily;
 var FontSize = document.body.style.fontSize;
 
 /* Checking and correcting font: */
 if (FontFamily != "Present LT std") {
  document.body.style.fontFamily = "Present LT std";
 }

 if (FontSize != "18px") {
  document.body.style.fontSize = "18px";
 }

}

Re: Javascript : Opens homepage when key is pressed

You can handle the keys pressed on the keyboard:

document.onkeypress = function(e) {
 return HandleKey(e);
}

function HandleKey(event2) {

     var key;  
     
     /* Retrieving the pressed key: */
	 
     if (window.event) {
          key = window.event.keyCode; //IE
     } else {
          key = event2.which; //firefox    
     }
	 
     /* Switching the pressed key: */
	 
     if (key == 97) {
	 
	alert("You pressed the left arrow!");
	return false;
		
     } 
	 
}

You only need to find the keycode of the "H" key.

Re: How do I make a Javascript to change a text from one font to another?

If you ask me: "does this code work?", you have not tested it out yourself at all, which is not advisable. Also commenting in JavaScript needs to be:

/* My comment */
// My comment

Anyway, the following function checks whether the body style (the style of the entire document!) is set to font family "Present LT std" and font size "18px", if it is not then sets it like that:

function FontChange() {

 /* Retrieving font: */
 var FontFamily = document.body.style.fontFamily;
 var FontSize = document.body.style.fontSize;
 
 /* Checking and correcting font: */
 if (FontFamily != "Present LT std") {
  document.body.style.fontFamily = "Present LT std";
 }

 if (FontSize != "18px") {
  document.body.style.fontSize = "18px";
 }

}

Re: How do I make a Javascript to change a text from one font to another?

You can modify the styles of elements easily:

Let's say you have some have an element with some text:

<span id='my_text' style='font-family:Arial;'>Some text</span>

Then you can use JavaScript to change its font family:

document.getElementById("my_text").style.fontFamily = "Times New Roman";

For all CSS properties and how to use them in JavaScript, see:

http://www.w3schools.com/CSS/pr_font_font-family.asp
(look at the JavaScript Syntax in the information table)

And look around the site for other CSS properties and how to use them

Re: Pass data from one form to another

Do you mean that the form is loaded without the page being refreshed/changed or with the page refresh?

Anyway, if the page is refreshed after the user pressed the button, you can just simply retrieve the form values using PHP and then echo that as values inside the full form:

// Retrieving the form values of the small form:
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];

// Echoing them inside the full form:

echo "First name: <input type='text' name='firstname' value='".$firstname."' />";
echo "Last name: <input type='text' name='lastname' value='".$lastname."' />";

// The rest of the form:

echo "Address: <input type='text' name='address' value='' />";
echo "Zip: <input type='text' name='zip_code' value='' />";

Or if you want the full form to show up dynamically (without page refresh) you will need to write a JavaScript function that either shows the rest of the form (which is hidden untill the button is pressed) or that retrieves the form values of the small form and then inserts them into the full form and then focusses the first input field within that form.

You can retrieve values using JavaScript with the following function (the id of the text input also needs to be set on 'lastname', just like its name):

var LastName = document.getElementById('lastname').value;

Re: Calling a function twice, help appreciated

You need to encase your code in code tags, one that opens, one that closes (without the spaces between the []):

[CODE ] Some code.... [/CODE ]

Anyway, on to your code:

  • You misspelled getElementById by changing the 't' into a 'd'
  • You kind of messed up the brackets in the CheckAnswer() function

The code was written OK, so my complements for that ;) I adjusted the code a bit so that it is more commented and spaced:

}

function CreateRandomOperator(){

  var Operator = "";

  var val = Math.floor(Math.random() * (1 + 1));

  if(val == 0) {
    Operator = "+";

Re: Calling a function twice, help appreciated

If you want to add other operators such as - / % etc, you need to replace the normal + in the form into:

<span id='Operator'></span>

And then adjust the CheckAnswer() function by adding the following to the part where you retrieve the values:

var Operator = document.getElementById('Operator').innerHTML;

Then you adjust the part where it checks for the correct answer:

if (Operator == "+") {
 ... Check the answer with the addition value
} else if (Operator == "-") {
 ... Check the answer with the substraction value
}

And so on for every operator!

But this also means you will need to adjust the CreateNewQuestion() function, as this now will also need to randomly pick a operator, so you will need to add a function to the entire script named CreateRandomOperator() which calculates a random number (for example 0-2) then returns a operator depending on what number is picked (so 0 = addition (+), 1 = substraction (-), 2 = division (/) etc...) and return that.

When you made that function, you need to make a adjustment to the CreateNewQuestion() :

function CreateNewQuestion() {

 var New_Number1 = CreateRandomNumber();
 var New_Number2 = CreateRandomNumber();
 var New_Operator = CreateRandomOperator();
 
 /* Loading the new numbers into the elements: */
 document.getElementById('Number1').innerHTML = New_Number1;
 document.getElementById('Number2').innerHTML = New_Number2;
 document.getElementById('Operator').innerHTML = New_Operator;

}

Re: Calling a function twice, help appreciated

Hi and welcome to DaniWeb!

When posting code, always make sure you put it between CODE tags:

Some code...

Now onto your problem:

You are starting off with jQuery before you even understand how JavaScript works. jQuery is an extension of JavaScript, making writing it easier.

As you have a question about the JavaScript/HTML of the page, the CSS you added on the bottom is not necessary.

I would recommend starting with JavaScript and then move to jQuery after you understand how it all works.

Below is an example on your project written in clean JavaScript, which is a bit more easy than jQuery:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

 <title>Asteroids</title>

var PlayerWins = 0; 
var PlayerLosses = 0;

function CreateRandomNumber() {
 
 /* Calculating and returning random number between 0 and 100 */
 return Math.floor(Math.random() * (100 + 1));

}
 
function CheckAnswer() {

 /* Retrieving the two numbers and the player's answer: */
 var Number1 = parseInt(document.getElementById('Number1').innerHTML);
 var Number2 = parseInt(document.getElementById('Number2').innerHTML);
 var Player_Answer = parseInt(document.getElementById('Player_Answer').value);

Re: Live Search Help

Using live search is a bit difficult to get working when it is your first AJAX related project, but anyway, here are some tips:

- First test whether the PHP page shows the correct HTML, by just visiting the PHP page in your browser and adding the GET variable manually:

liveresults.php?z=my+search+query

- Once that is working correctly, first make a simple function that alerts the variables you retrieve from the elements and call that first instead of directly start with the AJAX function (This step does not apply to you, as the variable is passed on by argument)

- Make the AJAX function and let it alert every step of the code, including whether the function is called at all, check the URL it is calling, what status and readystate it receives and what the responseText is

- When that is also working correctly, the problem should be solved ;) if not post below where it all went wrong

Re: Is what i need possible

You can in fact make a timer (= interval) that increments the variable 'play_time' every second, untill it reaches the end of the length of the song. Then it resets the play_time and load a new song. I am not sure how you play the song, so you need to incorporate that yourself:

var play_time = 0;
var current_song = 0;
var song_amount = 2;

var songs = new Array;

songs[0] = new Array;
songs[0]['length'] = 180; // In seconds
songs[0]['title'] = 'Song name0'; // Title of the song

songs[1] = new Array;
songs[1]['length'] = 230; // In seconds
songs[1]['title'] = 'Song name1'; // Title of the song

function HandleMusic() {

  if (play_time == songs[current_song]['length']) {

   /* Here you will have to place the code that plays the music.... */
   // Something like another function named PlaySong(song_id)

   /* Going to next song if it exists, else return to the first: */
   if (current_song != (song_amount - 1)) {
    current_song++;
   } else {
    current_song = 0;
   }

   /* Resetting play time: */
   play_time = 0;

  } else {

   /* Increasing play time: */
   play_time++;

  }
}

window.onload=function() {
setInterval(function(){

}, 1000);

Re: Button Code

Rounded corners is difficult if you want the browser to make it, but you can just simply use a image as background, that has rounded corners:

.Button2 {
background-image:url('images/button_out.png');
background-color:none;
border:0px solid red;
padding:0px;
width:100px;
height:20px;
}
.Button2:hover {
background-image:url('images/button_on.png');
background-color:none;
border:0px solid red;
padding:0px;
width:100px;
height:20px;
}

Also when you dont want to use a image, use regular CSS for it:

.Button1 {
font-family:Arial;
font-size:13px;
padding:2px;
border:1px solid white;
background-color:navy;
width:100px;
height:20px;
}
.Button1:hover {

document.getElementById(id).onclick=function(){mak('+opcija+',this.id);}
urediFont(opcija);
}

function mak(opcija,id){
document.getElementById(id).style.background="rgb(199,147,69)";
document.getElementById(id).onclick=function(){ozn('+opcija+',this.id);}
urediFont(opcija);
}

They need to be changed into:

function ozn(opcija,id){
document.getElementById(id).style.background="rgb(167,120,50)";
document.getElementById(id).onclick=function(){mak(opcija,this.id);}
urediFont(opcija);
}

function mak(opcija,id){
document.getElementById(id).style.background="rgb(199,147,69)";
document.getElementById(id).onclick=function(){ozn(opcija,this.id);}
urediFont(opcija);
}

PS: I do not have any clue which language this is, so all the variables names are confusing to me. Perhaps program in english so your code is more understandable to people. Just a suggestion for in the future ;)

Re: Rich editor - source code

When the user selects a text, he can press the 'B'-button to bold and to unbold the selected text. However, when he presses the 'B'-button without having the text selected, the user can enter text which will turn up bold. If the user wants to stop with this, he can unbold by clicking the 'B'-button.

Re: Rich editor - source code

Ivan, I see you used the tutorials I gave you to make a rich text editor, but you did not copy them correctly. For instance, line 9 and 10, you neglected to close the <body> and <html> tag, which is probably causing your problems.

If you want to change the background color of the selected text, you just simply use the following:

urediFont('BackColor', 'blue');

For a complete reference see:
http://msdn.microsoft.com/en-us/library/ms533049%28v=VS.85%29.aspx

I would highly recommend that you read through my tutorial again:
http://www.webdevproject.com/projects/solo/project31.html

Also, commenting/indenting on your code is advisable, as we can then understand the code alot better. (Code guidelines)

Re: php multiuser login

Yes it is ;)

You basically set session variable in which you declare various levels of authorization:

$_SESSION['LOGINDATA']['AUTH'] = 2; // 0 = guest, 1 = member, 2 = admin

And then you check on any page what to show:

switch ($_SESSION['LOGINDATA']['AUTH']) {

 case 0 :
  echo 'You are a guest';
 break;

 case 1 :
  echo 'You are a member';
 break;

 case 2 :
  echo 'You are a admin';
 break;

}

And if you need to check on a random page, to show a login message or not:

if ($_SESSION['LOGINDATA']['AUTH'] > 0) {
  echo 'You are not logged in, <a href="login.php">log in</a>?';
}

Also you need to add this to the top of you page, to make sure if the login session data is not set, you set it to default:

if (!isset($_SESSION['LOGINDATA']['AUTH'])) {

 /* Setting default value: */
 $_SESSION['LOGINDATA']['AUTH'] = 0;

} else {

 /* Converting the value to an integer, to prevent errors: */
 $_SESSION['LOGINDATA']['AUTH'] = intval($_SESSION['LOGINDATA']['AUTH']);

}

~G

PS: You always need to start a session at the top of every page ( session_start() )

Re: Can anyone solve this simple HTML error

It's not the fault of the HTML nor CSS, if you would read the sourcecode, you would see that after every dot (.) there is a unknown character icon. This is caused by your editor that you use to type the text (your CMS perhaps), which adds a unknown character after every dot.

~G

PS: You should validate your CSS using w3 CSS validator, on first glance, I saw that line 5 should be: font-style:none;

Re: somewhat confused with db connections

If you want to use two different DB connections, you need to start using the mysqli functions instead of the mysql functions. In the mysqli functions you need to specify which database connection you use to execute the queries and functions. Also, when selecting a database always use a or die() statement behind it:

$link = mysql_connect('localhost', 'mysql_user', 'mysql_password') or die("Could not connect to MySQL.");
$dbselect = mysql_select_db("mysql_database", $link) or die("Could not select MySQL database.");

Re: Need Help rewriting this Script

A) This is not the existing scripts forum
B) Send an email to the person that wrote this script and ask him to answer your question
C) The code is extremely unreadable, unclear and confusing. As I did not wrote the code, I have no idea what it does. It does not even have any comments.

I assume you did not wrote this script, and if you do you'd better improve your programming skills ;) (Code Guidelines: http://www.webdevproject.com/guides/programming/guide2.html)

Re: Darkening page in ie

When you want to darken a page, you place the following HTML right after the <body> tag:

<div id='darkscreen' style='position:fixed; top:0px; left:0px; color:black; opacity:0.5; filter:alpha(opacity=50); width:100%; height:100%;'></div>

If you want to toggle its display, you can use:

document.getElementById('darkscreen').style.display = 'inline'; // Show
document.getElementById('darkscreen').style.display = 'none'; // Don't Show

Re: currency converter

Making the converter can be done in JavaScript, like you showed on the link you added. I'il give you a head start on how to:

You have two text inputs, I already made the first for you:

The currency you have: <select id='have_cur_type' onchange='NewHaveCurType(this.value)'><option value='euro'>Euro</option><option value='dollar'>Dollar</option></select><br />
The amount you have: <input type='text' id='have_cur_amount' value='0' />
<br />
<br />
<input type='button' onclick='Convert()' value='Convert Currency' />

And then you have the javascript:

var have_cur_type = 'euro';
var need_cur_type = 'euro';

function NewHaveCurType(type) {
  have_cur_type = type;
}

function Convert() {
  
  var have_cur_amount = document.getElementById('have_cur_amount').value;
  // Also retrieve the other...
  
  // Now you need to calculate the ratio from one currency to the other, I would advise if you would first translate them all to one currency for example dollars and then translate those into the final currency the user wants

}

Re: Tinyeditor

Before I forget, I also decided to make a tiny editor myself after your question with an API etc. (but release date is about two weeks from now ;) ) but before I started my own, I created a tutorial on how to do make a tiny editor (aka a rich text editor). You might want to check it out:

Re: Tinyeditor

There is nothing tiny about it ;)

References and tutorials on developing rich text editors are rare and extremely difficult to find (I never found one till today). You should check out the open-source rich text editors and try to understand what they do in the sourcecode.

An example of an open-source WYSIWYG editor:
http://nicedit.com/

Try googling though to find the (maybe) one tutorial on the web on this subject? If you found it, feel free to post it below for others (including myself)!

EDIT:

Finally found one: http://www.webreference.com/programming/javascript/gr/column11/

EDIT2:

This one is better: http://www.geekpedia.com/tutorial198_Creating-a-Rich-Text-Editor-using-JavaScript.html
