How to set an <html:radio> checked by default in Struts 1.1

I'm trying to find out how to make a radio button checked by default when using jsp and struts 1.1 with custom tag.

When i write my code this way :

<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
....................................................................  
<html:radio property="operazione" value="addizione" checked="checked">Addizione</html:radio>  
<br />

eclipse say :

Undefined attribute name "checked"

and when i try to run this code on my server Tomcat this is what i get:

Attribute checked invalid for tag radio according to TLD

I've read this q/a but it involves JavaScript... Can you help me?

Solution

  • That doesn't involves javascript. All you need to do is set the property value in the respective action form. While loading the page, set the actionForm.property=value in the action class. If you required in javascript,

    (function() {
   // Set the value on loading the page
   document.getElementByID("elementID").value=1;
})();

    Hope this helps.
