This page is actually a login page consist of xhtml, ajax and php. When user enters email and pass and press login then a preloader appears and stucks there and doing nothing else. This happens on IE and safari.

here is the code

 

xhtml code

<link type="text/css" rel="stylesheet" href="css/style.css" />
<title>remindme</title>
<div class="loader">
<img src="images/ajax-loader.gif" width="27" height="27" />
    <div class="processing">Processing...</div>
</div>
<div class="login_banner">
Welcome to <div class="banner"></div>
</div>

<div class="login_border">
    <div class="login_form">
        <div class="login_heading">
            Login to <div class="remind"></div>
        </div><!-- login_heading -->
        <form id="login_form" action="main.php" method="post">
            <div>
                <label>Email address:</label>
                <input type="text" name="email" id="email" class="login_input" />
            </div>
            <div>
                <label>Password:</label>
                <input type="password" name="password" id="password" class="login_input" />
            </div>
            <div>
                <input type="button" name="loginbtn" id="loginbtn" value="Login" />
            </div>
        </form>
    </div><!-- login_form -->
</div><!-- login_border -->
<div class="error"></div>
<script type="text/javascript" src="lib/jquery-1.4.min(Production).js"></script>
<script src="js/script.js" type="text/javascript"></script>

 

here is jquery and ajax part

$(document).ready(function () {
//This is function triggers when login button is clicked.
$('#loginbtn').click(function (){
	hideshow('loader',1);
	var url = "login.php";
	//var queryString = $("#login_form").serialize();
	var email = $('#email').val();
	var password = $('#password').val();
	var queryString = 'email=' + email + '&password=' + password;
	//alert(email);
	//alert(queryString);
	$.ajax({
		type: "POST",
		url: url,
		data: queryString,
		dataType: 'json',
		success: show_login
	});		
});

//This function triggers when loginbtn process is successfully completed.
function show_login(resultData) {
	if(resultData.error=='no') {
		$('.error').css('visibility','hidden');
		$('#login_form').submit();
		hideshow('loader',0);
	}
	else {
		hideshow('loader',0);
		$('.error').html(resultData.fieldErrors).css('visibility','visible');
	}
}
});

 

here is php

<?php
