Question

My problem is, I want to retrieve checkbox id at runtime and use them later for other purpose.
But retrieved id is read as object.

My Code is:

 // Following code gives id of checkbox which contains myCheckbox as its id.

   var myCheckbox= $('input[id$=myCheckbox]')[0].id;

 //  and Now I want to check if that checkbox is checked with following code:


  if ($(myCheckbox).is(':checked')) 
    return 1;
  else 
    return 0;

But here myCheckbox id is read as Object instead of id and thus always enter in else condition and returns 0. This code works when I enter id of checkbox directly.

if ($('#ctl001_myCheckbox').is(':checked')) 
        return 1;
      else 
        return 0;

It shouldnot be so complicated, I have been working with Javascript but new to JQuery.

You are getting the ID correctly, but the jQuery selector requires the # symbol, much in the same way as a CSS selector does. You need to add the # character to your selector:

if ($('#'+myCheckbox).is(':checked')) 
    return 1;
  else 
    return 0;
