Get the data from server controls using javascript in asp.net

• Today I'll show you how to retrieve the server controls data easily using Javascript in ASP.NET.
• Normally people I have seen use to retrieve the data from controls is using  something like this:

function validate()

{

     var text=document.getElementById('<%=TextBox1.ClientId%>').value;

   // do stuffs

}

• And then more code for if you want dropdownlist data and some other controls.
• Instead simply one can use String function as (e.g. for DropDownList):

function validate()

{

     var text=String('<%=DropDownList1.SelectedItem.Text%>');

     var  value=String('<%=DropDownList1.SelectedItem.Value%>');

   // do stuffs

}

• That was for this blog have a great day. And yes any one having difficulty can comment anytime.
