Array.prototype.slice = function(begin, end) { end = (typeof end !== 'undefined') ? end : this.length; // For array like object we handle it ourselves. var i, cloned = [], size, len = this.length; // Handle negative value for "begin" var start = begin || 0; start = (...
1、this 参数可以传 null 或者undefined,此时 this 指向 window 2、函数是可以有返回值的 实现上面的两点很简单,代码如下 // 第三版 Function.prototype.call2 = function (context) { context = context || window; // 实现细节 1 context.fn = this; var args = []; for(var i = 1, len = argu...
