How JSP transform Struts tags using DOM ?

When I use DOM in javascript to construct a Struts tag, per example:

var new_obj = document.createElement("input")
new_obj.type='text'                    
new_obj.name='formLigacoesMultiplasCamadaIFrame'
new_obj.property='nomeLigacao'
new_obj.styleClass='SubFormTextbox'
new_obj.maxlength='10'  
new_obj.disabled='false'
parent_obj.appendChild(new_obj)    

JSP transform this in the following tag:

<input disabled property=”nomeLigacao” styleClass=”SubFormTextbox” maxlength=”10”>

But when i construct the tag in HTML:

<html:text name="formLigacoesMultiplasCamadaIFrame" property="nomeLigacao" styleClass="SubFormTextbox" maxlength="10" disabled="false"/>

JSP transform this in the following tag:

<input class=SubFormTextbox disabled maxlength=10 value=teste name=nomeLigacao>

Note: in the last tag, “teste” is the value that I gave to “nomeLigacao” in my Stuts action

Could anyone tell why this happens? I need to obtain the same result through DOM or through HTML.

Thanks

I'm not sure I understood your question, but if you're asking how to set the value of an input using the DOM, then you'd do it like this:

var new_obj = document.createElement("input");
new_obj.type='text';
new_obj.name='formLigacoesMultiplasCamadaIFrame';
new_obj.property='nomeLigacao';
new_obj.styleClass='SubFormTextbox';
new_obj.maxlength='10';
new_obj.disabled='false';
new_obj.value = 'teste';
parent_obj.appendChild(new_obj);

Hope that helps.

No, it isn't exactly that. I want to set the value and the other attributes of an input using my Struts action and my CSS within DOM

Wait, so you want Struts to interact with the DOM?  I don't really use Struts, but from my understanding, that's done on the server-side, isn't it?  The DOM is on the client-side, so you can't make the two interact very easily.  What exactly are you trying to do?  If all you want is to modify the HTML on a given page, the DOM should be enough.  I guess I'm just not following what the desired result is, so I'm not sure what to suggest.

Also, I just noticed that I was setting the CSS class wrong.  Instead of this:
  new_obj.styleClass='SubFormTextbox';
you should use:
  new_obj.className='SubFormTextbox';

I already solved my problem. I used innerHTML instead of DOM to construct the Struts tags. It works as i wanted: it uses the action that i defined.

Thanks dakyd

Glad to hear it's working the way you want, although anything you can do with innerHTML should be possible with the DOM as well.  *shrug* So long as it works.
