mootools_function的介绍

Function: Function.from 返回方法；

Function: Function.attempt 尝试方法

Function.attempt(fn[, fn, fn, fn, ...]);

Function method: extend 继承；

var myFunction = function(){};
myFunction.extend('alert', function(text){
    alert(text);
});
myFunction.alert('Hello!'); // alerts Hello!
 
// Using objects
myFunction.extend({
    alert: function(text){
        alert(text);
    }
});

Function method: implement 为原型添加方法。

var myFunction = function(){};
myFunction.implement('alert', function(text){
    alert(text);
});
var myInstance = new myFunction();
myInstance.alert('Hello!'); // alerts Hello!
 
// Using objects
myInstance.implement({
    alert: function(text){
        alert(text);
    }
});

Function method: bind 绑定事件

function myFunction(){
    // Note that 'this' here refers to window, not an element.
    // the function must be bound to the element we want to manipulate.
    this.setStyle('color', 'red');
};
var myBoundFunction = myFunction.bind(myElement);
myBoundFunction(); // makes myElement's text red
 
// To show how bind works the following example:
var myBoundFunction = myFunction.bind(anyVar);
// is roughly equivalent with
var myBoundFunction = function(){
    return myFunction.call(this);
};

Function method: delay 延时方法发生 var timeoutID = myFunction.delay(delay[, bind[, args]]);

var myFunction = function(){ alert('moo! Element id is: ' + this.id); };
 
//wait 50 milliseconds, then call myFunction and bind myElement to it
myFunction.delay(50, myElement); // alerts: 'moo! Element id is: ... '
 
//an anonymous function which waits a second and then alerts
(function(){ alert('one second later...'); }).delay(1000);
 
//to stop the delay, clearTimeout can be used like so:
var timer = myFunction.delay(50);
clearTimeout(timer);

 

Function method: periodical 周期性执行方法

ar Site = { counter: 0 };
var addCount = function(){ this.counter++; };
addCount.periodical(1000, Site); //adds the number of seconds at the Site.
 
// the interval can be stopped using the clearInterval function
var timer = myFunction.periodical(1000);
clearInterval(timer);
