獲取地址欄及參數

    getUrlArgObject(){ 
        var me=this;
        var args=new Object(); 
        var query=location.search.substring(1);//獲取查詢串 
        var pairs=query.split(",");//在逗號處斷開 
        for(var i=0;i<pairs.length;i++){ 
            var pos=pairs[i].indexOf('=');//查找name=value 
            if(pos==-1){//如果沒有找到就跳過 
                continue; 
            } 
            var argname=pairs[i].substring(0,pos);//提取name 
            var value=pairs[i].substring(pos+1);//提取value 
            args[argname]=unescape(value);//存爲屬性 
        } 
        me.canshuList=Object.keys(args);//args獲取到的參數對象,如果只想獲取到參數對象可掠過下面代碼。
        if( me.canshuList.length==0){//判斷參數對象是否爲空
            
        }
    }, 

Object.keys

返回一個所有元素爲字符串的數組

案例:

// simple array
var arr = ['a', 'b', 'c'];
console.log(Object.keys(arr)); // console: ['0', '1', '2']

// array like object
var obj = { 0: 'a', 1: 'b', 2: 'c' };
console.log(Object.keys(obj)); // console: ['0', '1', '2']

// array like object with random key ordering
var anObj = { 100: 'a', 2: 'b', 7: 'c' };
console.log(Object.keys(anObj)); // console: ['2', '7', '100']

// getFoo is a property which isn't enumerable
var myObj = Object.create({}, {
  getFoo: {
    value: function () { return this.foo; }
  } 
});
myObj.foo = 1;
console.log(Object.keys(myObj)); // console: ['foo']
