IE10一下的浏览器,如果在JS代码中用了bind函数,那么就会报“SCRIPT438: 对象不支持“bind”属性或方法”
因为浏览器没有提供这个参数的方法,所以我们就自己写一个bind,来让这个参数生效。
//解决IE10以下不支持Function.bind
if (!Function.prototype.bind) {
Function.prototype.bind = function(oThis) {
if (typeof this !== "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 && oThis ? this : oThis,
aArgs.concat(Array.prototype.slice.call(arguments)));
};
fNOP.prototype = this.prototype;
fBound.prototype = new fNOP();
return fBound;
};
}
