How to write a Simple jquery Code

How to write a Simple  jquery Code ??

Html code:


<input type="text" id="testid"  class="testclass" name="testname" placeholder="Event call using id on textbox click" >

<input type="text" id="testid2"  class="testclass2" name="testname2" placeholder="Event call using class on textbox leave" >


first thing download the latest jquery library from

http://code.jquery.com/jquery-migrate-1.2.1.min.js

then save it with "jquery-migrate-1.2.1.min.js" in your js folder or your project location


Jquery Code:

$(document).ready(function(){    // jquery start
    $("#testid").click(function(){    // text box click event
        alert("You have clicked");    // message to be displayed
    })
 });

This is the basic format for jquery beginner. you can use class instead of textbox id


$(document).ready(function(){    // jquery start
    $(".testclass2").blur(function(){    // text box blur event
        alert("This is use of class selector");    // message to be displayed
    })
 });


$(document).ready(function(){    // jquery start

    $("input").blur(function(){    // text box blur event on particular textbox
       
    $(this).css("border", "1px solid red");
       
    });
 });
