If you want to compare the value of `m` to `1`, you definitely don't want to be using `=` (that's the assignment operator). Instead use `==`. — Anthony Grist, Feb 24 '12 at 14:11
actually instead of checking m==1, i will get the value from user and used to check there. — jcrshankar, Feb 24 '12 at 14:19
@jcrshankar: whats the issue and i believe `=` is an assignment operator while `==` is comparison — Umesh Awasthi, Feb 24 '12 at 14:40
umesh i need to compare the value only, that' fine. i need help on how to call struts action from java script. plz help on this. — jcrshankar, Feb 24 '12 at 14:49

try it

window.location='youractionname'

This will redirect your window into your destination

If you want to sent your values to other page, then follow this method

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<script type="text/javascript">

function displayDate()
{

   var x=document.getElementsByName("userName")
if(x =="shan")
{   
alert("Redirecting");
return true;
}
else{  
alert("Not Redirecting");
return false;
}
}
</script>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
  <s:form action="HelloWorld"  onsubmit="displayDate();">
        <s:textfield name="userName" label="User Name" />
        <s:submit onclick="displayDate()" />
    </s:form>
</body>
</html>

What I modified is, changed the function calling from button to form submit. And removed the unwanted things from function

i believe OP has already found the solution of the answer as he mentioned in the comment.Still nice solution :) — Umesh Awasthi, Feb 27 '12 at 09:20
@UmeshAwasthi ,It is true that he found code to redirect his page. But from his question it is clear that he want to sent some form values along with it, which is not possible with the solution he found . ( Logical error) :-) — Sarin Jacob Sunny, Feb 27 '12 at 09:25

you can call action controller with parameter on click event

$('#loginSubmit').click(function(){ 

var Username= take the value for text fields 

var Password =take the value for text fields 
var url = "login"; 

var FormD = '<form method="post" action="' + url + '" id="frmSubmit" autocomplete="off">';

 FormD += '<input type="hidden" name="Username" value="' + Username+ '" />'; 

FormD += '<input type="hidden" name="Password" value="'  + Password+ '" />'; 

FormD += '</form>';
 $("body").append(FormD); $("#frmSubmit").submit(); 
});

try is:

function displayDate(){

    var x=document.getElementsByName("userName")
    if(x = "shan")
    {   
    alert("shankarasd");
    document.myForm.action ="/setUpForInsertOrUpdate";
    document.myForm.submit();


    location.href = "nameaction.action?parameter1="+value1+"&parameter2="+value2;
    }

}
