Dynamic Event Binding in JQuery


Create a sample form with button which used to create dynamic select tag and dynamic event binding


Here i am using the select tag for my test to bind the event dynamically. we are created a sample form that form contains one button for creating a dynamic select tag. We are going to write a change event for that dynamically created select tag. 

The following code may explain how can i write a events for dynamically created elements in html using JQuery. For that we need jquery.

Source Code:
<html>
<head>
<script src="jquery-1.6.js" type="text/javascript"></script>
<script>
var n=1;
$(document).ready(function(){
$("#createselect").click(function(){


var newelement=$(document.createElement('div')).attr('id','test'+n);
newelement.html('<label>select tag'+n+'</label><select id="selectid'+n+'" class="dynamicallycreated" ><option>option1</option><option>option2</option><option>option3</option></select>');
newelement.appendTo("#testing");
n++
});

$('select.dynamicallycreated').live('change',function(){
$(this).next('p').empty();
$(this).after("<p>"+$(this).val()+" is selected</p>");


});
});
</script>
</head>
<body>
<div id="testing">
</div>
<input type="button" id="createselect" value="create">


</body>
</html>    

This code is for creating any number of select tag and bind the change method for each element in dynamically. For that i used the live method also take class name as a selector of my test.

Data type precedence - SQL Server

       In SQL Server, data type precedence determines which data type takes precedence over others when two or more data types are combined or compared. It is important to understand data type precedence to ensure that the correct data type is used and that data is not lost or truncated during operations. In this blog, we will discuss data type precedence in SQL Server with examples. Data type precedence levels SQL Server has 16 data type precedence levels, with the highest level being 1 and the lowest level being 16. The data type with the lowest precedence is considered to be the "weakest" data type and is most likely to be converted to a higher precedence data type during operations. Here is the list of data types in SQL Server, ordered by their precedence levels: user-defined data types (highest precedence) sql_variant xml datetimeoffset datetime2 datetime smalldatetime date time float real decimal/numeric money/smallmoney bigint/i...

Uniqueidentifier Data Type – SQL Server

 In SQL Server, the uniqueidentifier data type is a 16-byte GUID (Globally Unique Identifier) that is used to uniquely identify rows in a table. This data type can be useful in scenarios where you need to ensure that each row in a table has a unique identifier. In this blog, we will explore the uniqueidentifier data type in SQL Server and provide a sample use case. Introduction to the uniqueidentifier data type The uniqueidentifier data type is a fixed-length data type that can store a 128-bit GUID. A GUID is a unique identifier that is generated using an algorithm that ensures that the identifier is globally unique. The uniqueidentifier data type can be useful in scenarios where you need to create a unique identifier for each row in a table, such as in a customer database where you need to ensure that each customer has a unique identifier. Creating a table with a uniqueidentifier column To create a table with a uniqueidentifier column, you can use the following code: CRE...
