Question

Prototype library uses $('element-id') or $F('element-id') to get the element or value of a form element. This is very convenient to code in javascript. But in Struts, I find there is no way to define an id attribute for a form element.

Although i can use

<html:xhtml/> 

to define a form tag with id attribute as follows:

<%@ page contentType='text/html;charset=UTF-8' language='java' %> <%@ taglib uri='http://struts.apache.org/tags-bean' prefix='bean' %> <%@ taglib uri='http://struts.apache.org/tags-html' prefix='html' %>  <html:xhtml/>   <html:form action='/Welcome'> ... <html:text property='username' size='16' maxlength='18'/> ... </html:form> 

The above rendered html is like this:

<form id='TestForm' method='post' action='/myapp/Welcome.do'> ... <input type='text' name='username' size='16' maxlength='18'/> ... </form> 

But what i need is to let struts render the

<html:text>  

tag like this:

<input type='text' id='username' name='username' size='16' maxlength='18'/> 

So is it possible in Struts to realize that? Or if not, how can i make it better to code in Prototype lib for Struts application?

I am using Struts 1.3.8; Prototype 1.5.1.

You can use the styleId attribute on most Struts widgets to set the HTML element id:

<html:text styleId='myId' .../> 

renders as

<input type='text' id='myId' .../>
