Some of us might want to disable the mouse right click .Below simple code snippet can be used to d the job easily using jQuery.

$(document).ready(function(){
$(document).bind("contextmenu",function(e){
return false;
});
});

As a web developer, most of the times you would have to do some functionality / operation before form gets submitted.By default form gets submitted on click of enter key when the input field is focussed.Below code snipppet can be used to avoid default form submision.

$(document).ready(function() {
$(”form”).bind(”keypress”, function(e) {
if (e.keyCode == 13) {
searchFunc($(”#searchInput”).attr(’value’)); //perform some operation
return false;
}
});
});

Below code snippet helps you to find the number of lines in the input textarea using Jquery & native RegEx functionality.

var textInput = $(”#textareaId”).val();
var lines = textInput .split(/\r|\r\n|\n/);
alert(lines.length);

As you know all new Joomla installations start with a Super Administrator account called, ‘admin’. During the installation process, you will be asked to give this account a password. That’s great as far as it goes, but because the user name of this highly-confidential account is generally well known, 50% of the security of the username/password combination is already exposed. Now all anyone needs to do is guess the password and they’re in.

By changing the user name to something more difficult to guess, you greatly increase the difficulty of accessing the account. An attacker must correctly guess both the user name and password at the same time to gain access. This is several magnitudes more difficult than simply guessing the right password.

Steps to Change the Default admin login

1. Log into the Back End
2. Select User Manager
3. Select the ‘admin’ user record
4. Change the value in username.
5. Save
6. Remember the new username!

Due to the increase in popularity of Web 2.0 applications and web services it has become increasingly important to be able to parse XML from the client browser.Parsing is not the easiest thing till the JavaScript libraries that supports XML made their way.

With jQuery, when you receive an XML from a callback (usually thro’ Ajax) which is basically a DOM (document object model) that jQuery can traverse seamlessly and efficiently to get the data you need.
we are using jQuery to parse XML due to its ubiquity& for cross browser compatibility.

The below xml file is used for reference.

<?xml version="1.0" encoding="utf-8" ?>
<country>
<state>
<city>Bangalore</city>
<id>24378</id>
</state>
<state>
<city>Chennai</city>
<id>42378</id>
</state>
<state>
<city>Mumbai</city>
<id>324782</id>
</state>
<state>
<city>Hyderabad</city>
<id>6524</id>
</state>
</country>

To parse the xml file we’re going to set up a function that will search each parent element and output the specified child element’s value as text using the find and each statement.The xml data gets parsed on success of ajax callback through parseXml function.Don’t forget to set dataType as “xml” while making an ajax call.
$(this).find(”city”).text() represents the textual value of city by striping the city tags -<city> &</city>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>xml parser using jquery</title>
<script type="text/javascript" src="/jquery-min.1.3.2.js"></script>
<script type="text/javascript">

});
}
});
</script>
</head>
<body>
<table id="Citylist">
<tr ><td >City List</td> <td >ID</td><tr>
</table>
</body>
</html>

The output would be displayed as below after parsing the xml file:
