Solution 1

If you are using s:submit tag the rendered HTML output is either input or button tag but the type is submit except for the image type. You can use the code to execute javascript onclick event that doesn't submit the form.

<s:submit type="button" onclick="return false;"/>

Solution 2

Have you tried preventDefault()?

$("btnSave").click(function(e){
    e.preventDefault();   
    //..rest of the code
});

I am using Struts2 framework in my application, I have one button on my JSP page. That is

<s:submit type="button" name="btnSave" />

Now, I want this button to behave as normal HTML button type should not submit the form and execute the Scripting function on onclick event. That function submit the form using Ajax.

But what happens is Struts2 convert it to

<input type="submit" id="add_btnSave" name="btnSave" value="Save"/>

And my form is submitted.

1) If I use the HTML button tag it will mess the GUI. As theme of my form is Ajax.

This is a head tag with script

<head>
<s:head theme="ajax"/>
<script type="text/javascript">

$("btnSave").click(function(){
alert("aaa");
$.ajax({
url:
type:"POST",
dataType: "json",
error: function(XMLHttpRequest, textStatus, errorThrown){
alert('Error ' + textStatus);
alert(errorThrown);
alert(XMLHttpRequest.responseText);
},
success: function(){
alert('SUCCESS');
}
});
});
</script>
</head>

My body tag is as followers :

<body>
<table border="1" width="80%" align="center">
<tr>
<td width="100%">
<s:tabbedPanel id="EmpDetail" useSelectedTabCookie="true">
<s:div id="one" label="Emp Reg." theme="ajax" tabindex="0" labelposition="top">
<center>
<s:form name="frmEmpReg" namespace="/" method="post">
EMPLOYEE REGISTRATIOM TAB<br>
<s:actionmessage />
<input type="hidden" name="empbean.id" value="<s:property value="empbean.id"/>"/>
<s:textfield label="Employee First Name" name="empbean.firstName"></s:textfield>
<s:textfield label="Employee Middle Name" name="empbean.middleName"></s:textfield>
<s:textfield label="Employee Last Name" name="empbean.lastName"></s:textfield>
<s:textfield label="Address" name="empbean.address"></s:textfield>
<s:textfield label="State" name="empbean.state"></s:textfield>
<s:textfield label="Employee Designation" name="empbean.designation"></s:textfield>
<s:submit name="btnSave" type="submit" value="Save" align="center"/>
</s:form>
</center>
</s:div>
<s:div>
..
..
Other Tabs
</s:div>
</s:tabbedPanel>
</td>
</tr>
</table>
</body>

any one have any idea of handling it with Struts2 then please help.

Your help will be really appreciated.
