jQuery is a very powerful library for making good interaction on your web application. However in ASP.Net development environment there is a problem that I found when selecting the ID of an ASP.Net control.

Usually we can select the id of specific html tag by using this

$(document).ready(function(){
$('#IDofSpecificTag').click(function() {
// do implementation here
)};
});


But when we want to access the ID of ASP.Net Control we cannot simply select the ID of the control, as when it rendered in html page (after it compiled) it will have some attachment (prefix) on the id.
For example, my asp:textbox with id txtBarcode it renders as ContentPlaceHolder1_txtBarcode in the generated html.

The Solution:

$(document).ready(function(){
$('# <%= IDofSpecificTag.ClientID %>').click(function() {
// do implementation here
)};
});


OR


$(document).ready(function(){
$("*[id$='IDofSpecificTag']")..click(function() {
// do implementation here
)};
});


I prefer the first solution as it is very simple in implementation, however it is not very good practice to mix up between ASP.Net tag with javascript..
I hope this will be useful for people who are still learning how to use jQuery in ASP.Net 🙂
