Re: wanna help..how to avoid default context menu

We're venturing off into another discussion. I don't know the particulars of the OP's environment or application, but in general, I say "hands off" on anything that is in the User Model. This includes such often-requested items as auto-sizing a window, auto-printing a page, disabling certain script warnings, obscuring or making "View Source" difficult, and replacing or editing the context menu.

This link should be of interest to you in regard to adding to context menu(s):

Re: wanna help..how to avoid default context menu

Wait... I know IE provides an "oncontextmenu" event handler. I'm not sure about FireFox.

You could code that in the body, as so:

<body oncontextmenu="return false;">

However, this is where I make my standard plea/warning: users expect that when they right-click, they get a context menu. I, for example, routinely use it to access "back". It's faster than mousing up to the top of the browser. Disabling or co-opting features that users have come to expect violates a basic application design principle, and should be avoided, in my opinion.

So unless you have a very compelling reason for doing this, I would suggest that you leave it alone.

Re: wanna help..how to avoid default context menu

I think you'll have to code to the Event object, which has cross-browser issues. But the Event object is created when any event occurs, and you might be able to tell if a click was a left or a right click and code accordingly. So my first thought would be to research the JavaScript "Event" object.

Re: Popup window

The best way is to author a JavaScript that does so. You don't want a complete server roundtrip just to open a window!

You can add scripts via "RegisterStartupScript" method of the Page object.

Re: How to pause webpage?

Sorry, but this doesn't make sense to me. Can you post a better pseudo-code example? If you have something that needs to execute before something else happens, code the first "thing" as a method that returns a value. Test the value, then move forward or not.

There should never be a need to do what you're asking to do.

Re: HELP THE NEWB! Posting in HTML...

You cannot do this with HTML alone. Or even, for that matter, JavaScript, which is a language to manipulate things (the web document, the browser, cookies) on the client. You'll need to learn at least a server-side language (may I suggest "PHP"), and likely a database and SQL.

Re: HYPERLINK with PHP POST

It's very simple. If you have a single form on the page, then this hyperlink would submit it:

<a href="#" onclick="document.forms[0].submit();">Submit form</a>

There are a couple of variations. I prefer to refer to all HTML elements via their ID property. So if you give your form an ID, like:

<form id="myForm" method="post" action="myFormProcessor.php">

then your hyperlink could be:

<a href="#" onclick="document.getElementById('myForm').submit();">Submit form</a>

Lastly, if you don't like having that href, you can also code it:

<a href="javascript:document.forms[0].submit();">Submit form</a>

Re: HYPERLINK with PHP POST

So, in fact you DO want to POST a FORM, you just don't want an "ugly button". Right? Then either style the button using CSS, or code almost any other HTML element, such as a hyperlink, to fire the form's "submit()" method.

(You might have had more answers, sooner, if you'd posted in the HTML/JavaScript forum rather than PHP.)

Re: Text Justification Algorithm

This is a HUGE topic. I work in printing/publishing, and code PostScript, so I've written my share of text justificaiton routines.

Simple approach: adjust the whitespace between words

Better approach: adjust the majority of the whitespace between words, the rest between individual spaces. I use 80/20, it seems to be the most balanced.

Sophisticated approach: add hyphenation. <-- may take years to get right!

Re: IE6 warning

I get no such message. You're probably testing/loading your pages LOCALLY. IE will indeed block scripts in pages that you load from your local file system. You can't, as far as I know, turn it off.

But never fear, people who browse to your page don't get the warning.

Re: Printing using Web Control Print button VB.NET

Make sure you use "Form1" instead of "myForm", for one thing. I don't see why you need two buttons. Or, why you need to set a Session variable. But that's all beside the point: it's saying it doesn't recognize "document.getElementById()"??

That is truly strange.

Take the "onlick=printMe();" out of your element declaration.

Re: Printing using Web Control Print button VB.NET

Your error is because, in ASP.NET-world, the "onclick" attribute points to SERVER code. So the compiler is looking for a "printMe()" method in your code-behind page. In a way, then, yes - it's because you're using a web control.

That's why I wrote previously:

ASP.NET is NOT traditional web development, however. For one, your "onclick" code for the button control refers to server code. That would be your audit code that checked for "printed=YES".

To get a client-side click event registered to a server control, you have to do:

Code:

myServerControl.Attributes.Add("onclick","printMe();");

Now, to get the hidden form element's value, you can either 1) turn it into a server object by adding the runat=server attribute to the element's declaration, or 2) use the ASP.NET Request object.

Re: Printing using Web Control Print button VB.NET

First, your print button can be an ASP.NET Web Server control, or not. Thinking it over, it might be good to use one, since then you can run both client and server-side code for it.

Let's talk about client-side first. You need to accomplish two things:

1) Open a print dialog box when the button is clicked.
2) Pass a value back to the server code that indicates the user clicked that button.

You accomplish the first task using the JavaScript window.print() method. You accompish the second task by setting the value of a hidden form element. You can do both tasks in a single JavaScript function. Here's a first attempt at what the code might look like:

<html>
<head>
<title>JavaScript Sample by tgreer</title>
<script type="text/javascript">
  function printMe()
  {
     window.print();
     document.getElementById("printed").value = "YES";
     document.getElementById("myForm").submit();
  }
</script>
</head>
<body>
  <form id="myForm">
    <input type="button" value="Print me" onclick="printMe();" />
    <input type="hidden" id="printed" />
  </form>
</body>
</html>

Now, in any traditional web development system, that would be pretty much it. The user would click the button, which would fire the script. The script opens the print dialog box, sets a hidden form element value, and submits the form.

The server code would parse the Request object to see if "printed=YES", and if so, do whatever it is you want to do.

ASP.NET is NOT traditional web development, however. For one, your "onclick" code for the button control refers to server code. That would be your audit code …

If this page was named "pickstate.html", and you loaded it with the querystring:

pickstate.html?state=1

Then, "Alaska" would be selected in the SELECT element.

Why do I say it's rudimentary? For one, the querystring parser isn't robust. Ideally, you'd parse the entire querystring into a JavaScript array, so you could pass in multiple values. Not important in your scenario. Also, it relies on "?state=" having seven characters, intead of finding the value by searching for the equal sign.

Next, the index has …

Re: Javascript generated drop down menu

I would append a querystring, containing the value of the previously selected state. Then, author an onload script that checked for the querystring value, and make that the selected option in the select list. If there is no querystring (ie/ first time the page loads), then select some default state.

Re: window location using frames

"Top" is the top-level window object in the hierarchy. Think of it as your "frameset" page.

So "top" contains all of your frames. You're saying, "go to the top window object, look into all the frames it contains, find the one named 'mainFrame', and set that frame's location to the URL 'www.tgreer.com'.

I'm not sure where the concept of "bottom" fits within the frame hierarchy. But you can refer to specific frames using an indexer of the frame collection:

frames[1], frames[2], and so on.

Also look at the "top" and "parent" objects, and possible the "this" keyword, the "self" object, and so on. Seeing some code would help us help you.
