JS 知识点集锦

 

1.JS 自执行函数(强制执行)

//1.
var arrayList = [1,2,3,4];
var getArrayList = (function(myList){
    var newList = new Array();
    if((myList!=null)&& (myList.length>0))
    {
        for(var i in myList){
           newList.push( myList[i]+1);
        }
    }
    return newList;
})(arrayList);
//2.
var t1 = (function(x, y){
    return x+y; 
})(2, 3);

 

2.JS面向对象的简单应用

var script = function(){};

script.css1;
script.css2;
script.css3;

script.init = function(){
    script.css1 = "abc";
}
script.init();

alert(script.css1);

 

3.JS Array数组排序

var list = [1,2,6,3,5,4];

list.sort(function(a,b){
    return String(a).localeCompare(String(b));
});
for(var i=0;i<list.length;i++)
{
    alert(list[i]);
}
