Learning jQuery

Sometimes It is required to add default option like "Please Select" or "Select" in Dropdown list. Below is a simple jQuery code to "add default option to ASP.NET Dropdown list using jQuery".

//Code Starts
$(document).ready(function(){
  var defaultOpt = "<option selected='selected' value='-1'>--Select--</option>"
  $('#<%=ddlCountry.ClientID %>').prepend(defaultOpt);
})
//Code Ends

And if you want to add default option to all the dropdown list on the page then use below jQuery code.

//Code Starts
$(document).ready(function(){
  var defaultOpt = "<option selected='selected' value='-1'>--Select--</option>"
  $('select').prepend(defaultOpt);
})
//Code Ends
