js数组对象操作

js_arrary_slice.js

var arr = new Array();
arr[0] = {"name":"LincolnBurrows","age":"26","sex":"male"};
arr[1] = {"name":"yangdong","age":"20","sex":"male"};
arr[2] = {"name":"jingjing","age":"19","sex":"female"};

arr.push({"name":"kkkk","age":"2222"});  //数组push方法，相反pop方法
arr.pop({"name":"kkkk","age":"2222"});

for(var i = 0;i < arr.length;i++)
	{
        
        console.log(arr[i]); //打印每一项
        
        var user1 = {name:"jingjing"};
        if (arr[i].name == user1.name) //或者直接等于"jingjing"字符串
        	console.log(arr[i]);
	}
