struts logic tag + javascript

[sgxbytes]

Hi,

My jsp has a text field company and i have two logic tags with properties years and none.
[HTML]
<html:text property="compa ny" onChange="showH int()" />

<logic:equal value="year" property="years " name="announcem entListForm">
<a title="year">By Year:</a>
<a title="2008" href="../announcementLis t.do?year=2008" >2008 </a>
<a title="2007" href="../announcementLis t.do?year=2007" >2007 </a>
<a title="2006" href="../announcementLis t.do?year=2006" >2006</a>
</logic:equal>

<logic:equal value="none" property="years " name="announcem entListForm">
</logic:equal>[/HTML]


i need to write a javascript such that when i change the value of my company in the text box i need to set the logic tag property to none ,only onChange().

i tried like

function showHint()
{

if(document.forms[0].years.value==null || document.forms[0].years.value=="years"  )
{
document.forms[0].years.value="none";
}
}

when i tried this way i am getting

document.forms[0].years.value is null or not an object.


how to go ahead with this...

Thanks
Raj

This is a JavaScript question; you've posted it in the Java forum. These two
languages have nothing to do with eachother. Do you want me to move your
question to the JavaScript forum?

Are you new to Javascript ?
The way you have interacted with the id is not correct.
you can use in this way

function check()
{
 var Field= $('Id of the field of which you want to validate').value;

if(Field=='Something' || Field='')
     {

         alert('Hi Friend');
     }

else
   {
     alert('Bye Friend');

   }


}

@sqxbytes, show the client-side version (HTML) version of your code, i.e. how it turns out in the browser when you view the source.

@Rsmastermind, he's not used the ID. Also, the $() function assumes that it's been defined somewhere. I would suggest document.getEle mentById() unless you know someone's using Prototype or some other library supporting it.
