在用 PhantomJS 运行 stdfn.CHAR = String.fromCharCode.bind(String);时报错：
TypeError: 'undefined' is not a function (evaluating 'String.fromCharCode.bind(String)')
经 google 一番发现文章 Function.prototype.bind is undefined #10522
原因：PhantomJS 调用 bind 返回 undefined
解决：Add Shim for Function.prototype.bind()，参考如下 MDN 的代码
if (!Function.prototype.bind) {
Function.prototype.bind = function(oThis) {
if (typeof this !== 'function') {
// closest thing possible to the ECMAScript 5
// internal IsCallable function
throw new TypeError('Function.prototype.bind - what is trying to be bound is not callable');
}
var aArgs = Array.prototype.slice.call(arguments, 1),
fToBind = this,
fNOP = function() {},
fBound = function() {
return fToBind.apply(this instanceof fNOP
? this
: oThis,
aArgs.concat(Array.prototype.slice.call(arguments)));
};
if (this.prototype) {
// native functions don't have a prototype
fNOP.prototype = this.prototype;
}
fBound.prototype = new fNOP();
return fBound;
};
}
不得不吐槽，PhantomJS 的 bind 实现方法居然都是错误的，ES5都多少年了，还不 fix。
