customised the locked textboxes and save as new data

Expand Post »

Hi.

How could we unlock the locked textbox whenever users click a button -say ' customise button'.
Then users are able to customise the boxes and save it as a set of new data with new ID?

Help is much appreciated.

Re: customised the locked textboxes and save as new data

hi
sorry but what you want...
if you want that somebody clicks on button that time textbox enable so you can call javascrit function on button click event
As i posted one example here

PHP Syntax (Toggle Plain Text)
<input type="text" disabled="disabled" name="txt1"/>
<input type="button" value="Click me" onblur="func_unlock();">
<script type="text/javascript">
function func_unlock()
{
	document.getElementByid('txt1').disabled=false;
}
</script>
<input type="text" disabled="disabled" name="txt1"/>
<input type="button" value="Click me" onblur="func_unlock();">
<script type="text/javascript">
function func_unlock()
{
	document.getElementByid('txt1').disabled=false;
}
</script>

Thanks

<input type="button" value="Click me" onblur="func_unlock();">
<script type="text/javascript">
function func_unlock()
{
	document.getElementByid('txt1').disabled=false;

</script>
<input type="text" disabled="disabled" name="txt1"/> <input type="button" value="Click me" onblur="func_unlock();"> <script type="text/javascript"> function func_unlock() { document.getElementByid('txt1').disabled=false; } </script>

Are you sure you don't mean onclick ?
That wouldn't fire when the button was clicked, but rather when the button is deselected.

Edit:
And you misuse the name attribute.
Only IE incorrectly fetches tags via the document.getElementById function based on their name attribute.
You should use the id attribute if your intend to fetch the element using that function.

Like:

html Syntax (Toggle Plain Text)
<html>
    <head>
        <title>JS Click Test</title>
        <script type="text/javascript">
        function EnableBox() {
            var box = document.getElementById('disabledBox');
            box.value = "";
            box.disabled = false;
            box.focus();
        }
        </script>
    </head>
    <body>
        <input id="disabledBox" type="text" disabled="disabled" value="I'm disabled" />
        <button onclick="javascript: EnableBox();">Enable</button>
    </body>
</html>
<html>
    <head>
        <title>JS Click Test</title>
        <script type="text/javascript">
        function EnableBox() {
            var box = document.getElementById('disabledBox');
            box.value = "";
            box.disabled = false;
            box.focus();
        }
        </script>
    </head>
    <body>
        <input id="disabledBox" type="text" disabled="disabled" value="I'm disabled" />
        <button onclick="javascript<b></b>: EnableBox();">Enable</button>
    </body>
</html>

Re: customised the locked textboxes and save as new data

Thanks Tulsa & Atil,
but as far I understand the example you gave is for a specific / one textbox.. Am I right?
What I intend to do is..
1- by clicking 1 button-"customise"..all textboxes will we unlocked
2- and we can update/edit the data in it..
3- subsequently save the data as a new set of data in a database.

I used to do it in VB but as I am a php newbie.. I don't have any ide of it.

Thanks in advanced

What are you doing? Tulsa & Atil explained how to enabled or disabled an item? Is there any problem to write a code for another textbox?

1-

is it possible to do this in Php? If not..it is ok..I might change my idea..edit the boxes individually & finally save it as a new set of data.

2- and we can update/edit the data in it..

Quote ...

3- subsequently save the data as a new set of data in a database.

Just insert [INSERT INTO] new data in databse, isn't it?
BUt How to update/increase the ID automatically in MySQL database. Logically ID+1, but I do not know the syntax.

Thanks in advanced

Thank you

Re: customised the locked textboxes and save as new data

If you want JavaScript to enable multiple boxes with one button click, you need to either statically fetch them all (like my example did, but with more than one box), or create a script to fetch all of the boxes you want.

The document.getElementsByTagName could fetch all the input elements for you so you could sort through them and find those you need to enable.

javascript Syntax (Toggle Plain Text)
var boxes = document.getElementsByTagName('input');
for(var i = 0; i < boxes.length; i++) {
  // Sort through the boxes here.
}
var boxes = document.getElementsByTagName('input');
for(var i = 0; i < boxes.length; i++) {
  // Sort through the boxes here.
}

You could give all the boxes that you need to enable a specific attribute to check, like 'doEnable', which you could fetch in your JavaScript code with the getAttribute function.
Like:

html Syntax (Toggle Plain Text)
<input doEnable="yes" .../>
<input doEnable="yes" .../>

javascript Syntax (Toggle Plain Text)
if(boxes[i].getAttribute('doEnable') == 'yes') {
  boxes[i].disabled = false;
}
if(boxes[i].getAttribute('doEnable') == 'yes') {
  boxes[i].disabled = false;
}

And P.S.
If you want to send multiple <input> boxes with the same name to PHP, they should be named <input name="name[]" .../> . That way all of them will be sent to PHP as an array, not just the last one in the form.
