javascript problem within my asp.net page

[tperri]

Im generating a GridView with some links, when the link is clicked it runs the following javascript function

        function changeElementStyleOn(elementName, styleName) 
        {   

        
            for (i=0; i < document.form1.elements.length; i++)
            {
            // do some stuff, window.alert is for testing
            window.alert(document.form1.elements[i].name);
            }
        }

the problem is, the loop is only finding 4 elements - the elements that asp.net generates:

    <form name="form1" method="post" action="Default.aspx" id="form1">
<div>
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value=""/>
</div>

and no other items on the page. Perhaps this is an error in my logic, but what Im trying to do is loop through the tables created, and if an item (a <tr>) has a class with a certain name, I need to do some processing on the class name. This part I have working, it's just I might be using the wrong javascript function to look at everything... but I looked at the MSDN library and it said searching using the form elements works for everything but image elements.

Can anyone point me in the right direction?

thanks!

Table elements are not part of a form. You'll have to dig into the divs and classify your table elements.

philhege,

Thank you for the reply. This is a new concept for me, do you have any links you can send me that have some samples so I can learn how to do this?

Thanks tons

You can start with the spec at

Pay particular attention to the getelementbyid method.

Thank you, I do understand the GetElementById -

My dilema is that I dont automatically have access to the id's I generate for the <tr>'s created in my GridView.

Basically, if I click a link to an item, all other of those items that dont have ID need to collapse. That is why I was trying to see if I could iterate through the table items created by the gridview, somehow, to do this.

I think you should be able to get a reference to all of the <tr> tags but using either the getElementsByTagName or childNodes methods. I'd ask in the javascript forum for which is the best method though.
