how can I access this inside a function without using that or self in javascript? -

im trying write oop in javascript, , stumbled upon problem sure im going have later on in code , wish deal now.

for illustration take code:

var feedclass = function(){ this.init = function(){ this.loaditems(); }, this.loaditems = function(){ var = this; // heres problem function inner(){ that.startloading(); } inner(); }, this.startloading = function(){ alert("started loading"); } this.init(); }; var feed = new feedclass();

the problem im going utilize lot of inner functions phone call "this", code messy if kept writing var = this within every scope. there pattern can utilize or way around it?

you can utilize call method set context function:

this.loaditems = function(){ function inner(){ this.startloading(); } inner.call(this); },

the apply method works similarly, difference how specify parameters in call.

you can utilize bind method set context of function. allows bind context function , pass function reference on called later:

this.loaditems = function(){ function inner(){ this.startloading(); } var = inner.bind(this); i(); },

note: bind method not supported in ie 8 or earlier.
