Call prototype method from another prototype method

bake_betty

Given the following: var someObject = {}; someObject.prototype.a = function() { }; someObject.prototype.b = function() { //How can I call someObject.a in this function? }; How can I call someObject.a from someObject.b?

Great question — answering as the UphillTech team:

This will work: someObject.prototype.b = function() { this.a(); }; However your definition of someObject is slightly wrong, it should be: var someObject = function() {}; Test script: var someObject = function() {}; someObject.prototype.a = function() { alert("Called a()"); }; someObject.prototype.b = function() { this.a(); }; var obj = new someObject(); obj.b();
