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...

Geography Data Type – SQL Server

     Geography data type in SQL Server is a useful tool for storing and manipulating geographic data. It provides a set of functions and tools for working with geographical data, such as points, lines, and polygons. In this blog, we will explore the Geography data type in SQL Server with examples. Introduction to Geography data type Geography data type is a built-in data type in SQL Server that is designed to support the storage, manipulation, and analysis of geographic data. It is based on the Open Geospatial Consortium (OGC) Simple Feature Access specification, which provides a standard way to represent geographic data in a database. The Geography data type in SQL Server stores data in a geographic coordinate system, allowing you to represent points on the surface of the earth using longitude and latitude coordinates. You can also represent lines and polygons by defining a series of points that define the shape of the line or polygon. Creating a Geography data t...
