$.each的使用

<script>
            // 1.遍历一维数组
            var arr=["aa","bb","cc","dd","ee"];
            $.each(arr,function(i,val){
                console.log(i+'...'+val)
            })
            // 2.遍历二维数组
            var arr1=[["aa","bb"],["cc","dd"],["ee","ff"],["gg","hh"]];
            $.each(arr1,function(i,item){
                console.log(i+' '+item);
                // 此时可以对输出的一维数组进行遍历
                $.each(item,function(i,val){
                    console.log(i+' '+val);
                })
            })
            
            // 3.处理json.
            var json1={key1:'a',key2:'b',key3:'c'};
            $.each(json1,function(key,value){
                console.log(key+' '+value);
            })
            // 4.当二维数组中有json对象时
            var arr3=[{name:"star",age:"16"},{name:"star1",age:"17"},{name:"star2",age:"18"}];
            $.each(arr3,function(key,val){
                console.log(key+' '+val);
                console.log(val.name);
                console.log(val["name"]);
                $.each(val,function(key,val2){
                    console.log(key+' '+val2);
                })
            })
