Answer 1

This is way to get return value using javascript:

function myFunction(value1,value2,value3)
{
}

var returnValue = myFunction("1",value2,value3);

if(returnValue.value1  && returnValue.value2)
{
//Do some stuff
}

This is way to get return value using jquery:

function getMachine(color, qty) {
    var retval;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            retval = thisArray[3];
            return false;
        }
    });
    return retval;
}

Answer 2

Use:

OnClientClick="return //javascript code"

instead of

onclick

Answer 3

Try this:

var returnValue;

$(document).ready (function(){

      var myButton =  $("#yourbuttonsid");

      var originalEventHandler = myButton[0].onclick;

       myButton.click(function(e) {

             returnValue = originalEventHandler();

          });


});

//Here you can do anything with returnValue
