| | | Ajax Form Submit | Ajax Form Submit 2007-02-01 - By Siva Gurusamy
Back
HI,
I am having a problem in using ajax in Struts 2 Application.
Can someone explain me how to resolve this issue.
I have a form and an ajax div in the page. On submit of the form I wanted to
reload ajax div. But result was, after doing submit form, 'undefined' text
was appeared in targets (resultDivId) for a second and then browsers url got
changed to form submit url. Hence, the result which needs to appear in
targets(resultDivId) appeared in entire browser.
My Code:
JSP:
<%@(protected) prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Ajax Examples</title>
<!--// START SNIPPET: common-include-->
<s:head theme="ajax"/>
<!--// END SNIPPET: common-include-->
</head>
<body>
<div id="createResult"></div>
<s:form id="createId" action="createajax"
namespace="/" method="POST" theme="ajax">
<s:textfield label="AccountName"
name="accountName"/>
<s:submit value="Save" name="Save"
resultDivId="createResult" notifyTopics="topicCreated" theme="ajax"
errorText="Error" showErrorTransportText="true"/>
<!--s:submit action="!cancel"
value="Cancel" name="Cancel"
onclick="form.onsubmit=null"/-->
</s:form>
<h1>Users</h1>
<s:div
id="userlists"
cssStyle="border: 200x solid blue"
href="ajaxList.action"
theme="ajax"
delay="1"
errorText="There was an fatal error"
showErrorTransportText="true"
listenTopics="topicCreated"
loadingText="Loading users...">Loading...
</s:div>
</body>
</html>

UserAction.create method
public String create() {
// This is just preparing the form prior to saving the new
user
actionType = CREATE;
System.out.println("-- -----> Going to create new user
(name)=" + accountName);
User u = new User();
u.setUserId(userId);
u.setAccountName(accountName);
try {
userService.createUser(u);
} catch (Exception e) {
e.printStackTrace();
System.out.println("Adding error to
ActionError...");
//addActionError(e.toString());
}
return SUCCESS;
}
createerror.ftl:
