Question

I am working on ajax using struts 2 frame work. Application has two text boxes "name" and "age". On submitting , those two values should be updated using div tag on the same page itself.

<sx:div id="div2" executeScripts="true" theme="ajax">Value</sx:div>


<sx:submit targets="div2"  value="submit">

when i use "targets" attribute in sx:submit ,getting some exception. when i remove "targets" no exception has been thrown.But application needs "targets" attribute to update the div tag.Do i need to any handle exception ? I am trying this as a sample exmple , my application needs this kind of functionality. Help me.

Source code as follows :

<%@taglib  uri="/struts-tags"  prefix="s"  %>

<%@taglib uri="/struts-dojo-tags" prefix="sx" %>

<html>

<head><title>Ajax_Div_Tag_Example</title>

</head>

<body><h1>Ajax_Div_Tag_Example</h1><hr>

<sx:div id="div2" executeScripts="true" theme="ajax">Value</sx:div>

<s:form action="resultAction">

<s:textfield name="name" label="Name"></s:textfield>

<s:textfield name="age" label="Age"></s:textfield>

<sx:submit value="submit" targets="div2"> </sx:submit>

</s:form>

</body>

</html>

<action  name="resultAction"  class="ActionClasses.AjaxDivAction">
        <result name="success">/resultPage.jsp</result>
        </action>

Is it because you are using `` instead of `
`? Not sure why you are using `` since _This tag generates an HTML div that loads its content using an XMLHttpRequest call, via the dojo framework_ according to the tag documentation at http://struts.apache.org/2.1.6/docs/dojo-div.html — nmc, Jun 30 '11 at 13:21
No i don't think so.If i use
, i have to write javascript to create XMLHttpRequest. — Jagan, Jun 30 '11 at 13:28
I don't see any `href` property in your `` tag so I assume you don't need XMLHttpRequest call? — nmc, Jun 30 '11 at 13:30
See the example. http://www.roseindia.net/struts/struts/struts2.2.1/tags/div_tag.html — Jagan, Jun 30 '11 at 13:30

First the struts2 ajax tags have been deprecated, I'll come back to this.

Not looking too long, you are missing the sx:head tag... Please see: http://struts.apache.org/2.2.1.1/docs/tag-reference.html It is the sx:head tag which inserts most of the required JavaScript. After that you'll be a lot closer.

Back to the taglib being deprecated... Simply any ajax tag library is brittle. Simple things are simple, any thing more than that becomes next to impossible. You will have far more flexibility if you invest some time in a JS library such as jQuery and it is very trivial to use the struts2-json-plugin. The audience for your UI questions will go up by several factors as your audience will not need to know anything about struts2 or even Java.
