javascript function doesn't execute

Question 1

Hi,I have simple login form, where fields are validated by javascript. I don't now why the below code is not working.

my html and js code:

<head>
 <script type="text/javascript">
 function handleLogin() {
 var u = $("#username").val();
 var p = $("#password").val();
 if(u=="a" && p=="a")
 {
 window.location="/Site/site.html";
 }
 else
 {
 alert("Fail");
 }
 }
 </script>
</head> 
<li dojoType="dojox.mobile.ListItem"> 
 <input dojoType="dojox.mobile.app.TextBox" placeHolder="username" type="text" id="username" name="username" />
 </li>
 <li dojoType="dojox.mobile.ListItem">
 <input dojoType="dojox.mobile.app.TextBox" placeHolder="password" type="password" id="password" name="password" />
 </li>
 <li dojoType="dojox.mobile.ListItem">
 <input dojoType="dojox.mobile.Button" onclick="handleLogin()" type="button" id="submit" name="submit" value="Login"/> 
 </li>

When I click on the submit button nothings happening.

Thanks

Question 2

Are you getting any error in firebug console ?

Question 3

Did you actually load jQuery?

Question 4

do you get any error ? Are you sure the function isn't executed ?

Question 5

works fine for me: jsfiddle.net/EnkrT

Question 6

I didn't get any errors.

Question 7

You didn't load the jQuery library. But you can do without it:

var u = document.getElementById('username').value,
p = document.getElementById('password').value;

Changing the page is done with location.href instead of window.location:

location.href = '/Site/site.html';

Question 8

I don't want load jQuery and I forgot when I wrote this. This solution without jQuery doesn't work

Question 9

@user1031034 Oh, I've corrected a typo; that was probably it.

Question 10

@dreamweiver Node.val() is not a function in pure JS and getElementById() doesn't take a selector.

Question 11

Now it's work :) but only when I have incorrect data in form. But when I have corect it's do nothing. It's good redirect to other site in javascript (without jquery). window.location="/Site/site.html";

Question 12

@Jack: Thanks for the correction jack, typical mistake when you are addicted to jQuery lib :)

Question 13

try to import

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
