Question

I am trying to call a method in the callback function.

jsTest.prototype.getTitle = function() {
   thisJS=this

   //the console will returns my object...so it's not undefined.
   console.log(thisJS);


   //codes.....


   //ajax callback function
    ajaxcall.callback=function(data){

        //call the addName method
        thisJS.addName(data, 1);

    };

}


jsTest.prototype.addName=function(data, bool){
    console.log(data);
}

I got an error saying

Uncaught TypeError: Cannot call method 'addName' of undefined 

Are there any ways to solve this? Thanks so much!
