Dynamic code in Body, after load

[pamelafluente]

Hi guys,


I am trying to add some code in the body of a document just
after it has loaded. I have the following code (this is referenced in
an html page).

When I click on the document I receive this error: "realSrc is null"

I guess I am not doing correctly the part of dynamic code. Can you help
?


//-------------------------------
var submitURL = "../../MyEngine/MyProcessor.aspx";
var HiddenFieldID = "actionCodes";

window.onload = addCellHandlers;

function addCellHandlers() {

//some code here to add some dynamic handlers


document.body.innerHTML += "<form name='form1'
method='get'><input type='hidden' id=" + HiddenFieldID + "/></form>"
document.form1.action = submitURL;

window.status = "Handlers attacched";
}


//-------------------------------

As far as I can tell, the error is not caused by the code you have
posted, though it may be related in some way to what you haven't
posted.

var submitURL = "../../MyEngine/MyProcessor.aspx";

Your error is likely related to the above missing code.

Actually you are right. I am also using:

http://webfx.eae.net/dhtml/pngbehavior/pngbehavior.html

to fix png transparency in ie6. if you see the script on that page
there is a point:

// check for real change
if (src == realSrc) {
element.src = blankSrc;
return;


here the code gives error because it finds realSrc Null.

Actually I have no idea how to fix this.
Let's forget about it, because ...


.... I have also find another way to fix the transparency problem.
It's quite the same trick but probably better implemented.
I can see less flickering.

It is here:

http://blog.bjorkoy.com/2006/12/12/flawless-and-fast-png-support-in-ie6/


BUT... even with this second method my simple dynamic code does NOT
work.

There must be some interference between the dynamic code

document.body.innerHTML += "<form name='form1'
method='get'><input type='hidden' id=" + HiddenFieldID + "/></form>"
document.form1.action = submitURL;

and the component code.


But I do not know javascript well enough to fix it.

Does anybody know ??
