get element by long name

[Tony Smith <qu...@yahoo.com>]

in my jsp, there is something like:

<html:text property="plateDetail.name"
value="${plateDetailEditForm.plateDetail.name}"  />


How can I get this element in javascript? the
following code does not work:

var name =
document.getElementByName("plateDetail.name").value;

I think it is because there is a '.' in the name.

Any idea?

Thanks,

qq

I think there is some confusion regarding server-side execution versus 
client-side execution. code like ${plateDetailEditForm.plateDetail.name} 
is entirely server-side as is the plateDetailEditForm object. You are 
trying to access that directly from the client which can't be done. You 
can try this solution and it will work for individual values:

 var name="${plateDetailEditForm.plateDetail.name} "

Tomcat will replace the ${...} expression with the value as the page is 
sent to the client. JavaScript on the client will get var name="name value".

Get Element By Name goes for the HTML name, like "h1",
"body", etc. For CSS and JavaScript access, you can
use element ID, like this:

<html:text property="plateDetail.name"
 value="${plateDetailEditForm.plateDetail.name}"
 styleId="plateDetailName" />

<script type="text/javascript">
<!--
    name = getElementById( "plateDetailName" );
    alert( name.value );
//-->
</script>

Nix.
