Been playing with your problem a few minutes and think Ive found the
problem.
Firstly your syntax was wrong.
What you meant to say was:
td5.setAttribute("ondblclick","alert('hello');");
instead of
td5.setAttribute("ondblClick=alert('hello')");
BUT unfortunately this correction still doesnt make it work....
As far as I can figure out, once you are at the stage of playing with the
browsers in-memory dom (as opposed to the unparsed source for the dom) then
the onXXX attributes dont take script source, but rather they take a
reference to a function. Im guessing that in the process of parsing the
source, the browser will convert the script in the onXXX attributes into a
function and substitute a reference to the function in the dom.
ie:
function foo()
{
alert('hello');
}
td5.setAttribute("ondblclick",foo);
or alternatively the simpler notation
td5.ondblclick = foo;
See the following example (which our email clients will no doubt mangle
badly!):
##########################
<html>
<head>
<script type="text.javascript">
function foo()
{
alert('hello');
}
function doTest()
{
var td5 = document.createElement("textarea");
td5.setAttribute("name","mytextarea");
td5.setAttribute("cols","10");
td5.setAttribute("rows","2");
td5.setAttribute("wrap","PHYSICAL");
td5.setAttribute('ondblclick',foo);
document.getElementById('test').appendChild(td5);
}
</script>
</head>
<body id="test" onload="doTest()">
</body>
</html>

Subject: [OT] dom - createElement("textarea") cannot invoke javascript
Hi All,
I would be obliged if someone helps me in this.
I am dynamically creating rows in my jsp by using the dom-tree functions
To create a text field i use :-
document.createElement("<input name='type"+indexVal+"' type='text'
size='3' maxlength='3' ondblClick='alert(this.value)'>");
The above code works fine and on double clicking, the the alert is invoked.
Now to create a text area using dom i use the following code :-
var td5 = document.createElement("textarea");
td5.setAttribute("name","mytextarea");
td5.setAttribute("cols","10");
td5.setAttribute("rows","2");
td5.setAttribute("wrap","PHYSICAL");
Now i wish to add a javascript event to this text area and so i tried the
following
td5.setAttribute("ondblClick=alert('hello')");
But this does not work. Can anyone please tell me how to add javascript
events to a text area that is generated like this.
Thanking in advance,
Vijay
