Question

Within my a certain function of a class, I need to use setInterval to break up the execution of the code. However, within the setInterval function, ‘this’ no longer refers to the class ‘myObject.’ How can I access the variable ‘name’ from within the setInterval function?

function myObject() {     this.name = 'the name'; }  myObject.prototype.getName = function() {     return this.name; }  myObject.prototype.test = function() {     // this works     alert(this.name);      var intervalId = setInterval(function() {         // this does not work         alert(this.name);          clearInterval(intervalId);     },0); } 

Answer 1

myObject.prototype.test = function() {     // this works     alert(this.name);     var oThis = this;     var intervalId = setInterval(function() {         // this does not work         alert(oThis.name);          clearInterval(intervalId);     },0); } 

This should work. The anonymous function’s ‘this’ is not the same ‘this’ as your myObject’s ‘this.’
