Javascript qestion, document.body.createTextRange() in Firefox?

[sciguyryan]

Hi all,


Can anyone convert this code to make it Firefox compatible?


<script type="text/javascript">
<!--
function Change(I, I1) {
var Range = document.body.createTextRange();
Range.collapse(true);
if (location.href.indexOf("action=") != -1){
return false;
}
else{
while (Range.findText(I)){
Range.text = I1;
Range.collapse(false);
}
}
}
//-->
</script>



Thanks for the help,

There is no equivalent to createTextNode in Mozilla Firefox.

Unless someone (such as Charles) can correct me. ;)

Google for setSelectionRange, undocumented, but will work

The key is that findText() method for the Range in IE, and I don't think Moz has anything comparable. setSelectionRange() won't do it alone--that's equivalent to createTextRange().

By the way, in your function there is no reason to create a TextRange if you are going to return from the function:

function Change(I, I1)
{
if (location.href.indexOf("action=") != -1) return false;

var Range = document.body.createTextRange();
Range.collapse(true);

while (Range.findText(I))
{
Range.text = I1;
Range.collapse(false);
}
}

Great function. :)

Actually I do.

The script was written for a forum (IF) and the indexOf line checks that a users is on the board and that the ACP is not affected.
The rest finds the text and then changes it.

What exactly do you want the function to do? Can you describe how the function is used?

[sciguyryan]

Ok,


It checks the local URL for action= (Anshures in the forums)

Next, it finds the first perameter and then replaces that with the second one.


Thats it.

Yes, I read the code. Good luck!
