Question

I have a JavaScript function which i call in the onchange handler of a dropdownlist. If the selected value of dropdownlist is “1” i want to call one function in codebehind.
Following is the function in JavaScript:

function  GetAdmissionType()
    {
        InitComponents();
        var type="";
        type=document.getElementById(dlAdmissionType.id).value;
        document.getElementById(hdnAdmissionType.id).value=document.getElementById(dlAdmissionType.id).value;
        if(type=="1")
        {
        }
  }

If type is 1 then i want to work following code in codebehind

public void LoadSemesters()
{
   //code to load other dropdownlists
}

Can anybody help to call function in codebehind from JavaScript?

Answer 1

The easiest way to do that is to expose the codebehind function as a web service call and use something like jQuery to call it from Javascript.
