    //each的方法
    <script type="text/javascript">
    			数组中的each
    			 var arr=["one","two","three","four"]

    				$.each(arr1,function(i,item){
    					alert(item[1]);  
    				});
    			//其实arr1为一个二维数组,item相当于取每一个一维数组,   
    			//item[0]相对于取每一个一维数组里的第一个值   
    			//所以上面这个each输出分别为:1   4   7  
    			var obj={one:1,two:2,three:3,four:4};
    			$.each(obj,function(i){
    				alert(obj[i])
    			})
    			//这个each就有更厉害了,能循环每一个属性     
    //each在input按钮中使用情况
    $.each($("input:hidden"), function(i,val){
    alert(val); //输出[object HTMLInputElement],因为它是一个表单元素。
    alert(i); //输出索引为0,1,2,3
    alert(val.name); //输出name的值
    alert(val.value); //输出value的值
    });
