Accessing form elements for Netscape 4.7

[dj4uk]

I have some JavaScript that accesses an element in a form:

window.document.forms[formID].elements[elementID].value

Where formID contains the name of the form and elemntID contains the name of the element. This works fine with IE and newer versions of Netscape.

How can I change this so it will work with Netscape 4.7? - I don't mind if I need to do a check for browser version and use a different code for the different browsers.

Any help appreciated.

Make sure all form elements have both the the id and name properties set.

Yes they are the same. But I'm not sure I have explained well enough...

function resetFormField(formID,elementID,defaultText) {
if (document.forms[formID].elements[elementID].value == defaultText) {
document.forms[formID].elements[elementID].value = '';
}
}

This javascript function is called by an onFocus event:
<input type="text" name="textfield" id="textfield" value="Enter keywords here" onFocus="resetFormField('FreeTextSearch','textfield','Enter keywords here');">

Works fine in IE and newer version of Netscape.

Any ideas?

Yeah. Ignore NS 4 It's a terrible browser anyway.

Is the function even called in NS4? Maybe it doesn't know the onFocus event. Use an onClick instead.

I can't ignore NS4 (true it is a truely terrible browser) but unfortunately people still use it!

I'll check if NS4 recognises the onFocus event. Can't use onClick for this particular instance.

Thanks.

Just checked up and onFocus is available for IE4+ and NS3+ so that can't be it.

I've got a feeling the problem is caused by the form and element name being created dynamically in the javascript code.

[CornedBee]

Very likely, yes. Have you tried with predefined ones?

Note also that NS on Mac never recognizes names that contain an underscore.
