The delay execution function _javascript skill of Javascript function object extension

Do you want to use the SetTimeout method of the Window object? Bingo, that's right! If you are in an application often to "delay the execution of a certain function", then based on the dry principle, can be extended for the function global object, add a delay to the functions such as delay, which will make your code more concise and effective.
The extension Function object adds delay method as follows:

Copy Code code as follows:

Function.prototype.delay=function (this1,timeout) {
this1=this1| | Null
timeout=timeout| | 0;
var _this=this;
var args=[];
Get parameters, note: The 1th and 2nd parameters are reserved parameters
Switch (arguments.length) {
Case 1:
Timeout=parseint (Arguments[0]);
Timeout=isnan (timeout) 0:timeout;
timeout=timeout<0?0:timeout;
Break
Default
for (Var i=0;i<arguments.length;i++) {
if (i>1) {Args.push (arguments[i]);
};
Break
};
var proxy=function () {
_this.apply (This1,args);
};
Return Window.settimeout (proxy,timeout);
};

Under the console of the Firefox firebug plug-in test, code like:

Copy Code code as follows:

var xx=function (n) {
This.name=n;
};
Xx.prototype.hi=function (a,b) {
Console.log (this.name+ "-" +a+ "-" +b);
};
var xx1=new xx ("Levin");
var t=xx1.hi.delay (xx1,1000, "Cocoa", "yoyo");
Xx1.hi ("Guluglu", "Jigujigu");
