Object.defineProperty alternative for IE8

Question

Given javascript code like the following (extracted from a plugin referenced below):

var AutosizeInput = (function () {
    function AutosizeInput(input, opt         


        

Answer 1

IE8 does not support getter/setter functions on properties of non DOM objects.

The "solution" here is to not rely on property getters, and use a full getter function instead.

AutosizeInput.prototype.getOptions = function() {
  return this._options;
};

var input = new AutoresizeInput();
input.getOptions();

Or, instead of keeping this._options as an "internal" variable, just drop the underscore allow access directly. This way you need no magic at all.

var AutoresizeInput = function() {
  this.options = {};
}

var input = new AutoresizeInput();
input.options();
