jquery 遍历 对象数组 问题

[nihao955]

               var ddd = new Array();
                for (var i = 0; i < 10; i++) {
                    var aaa = new Object();
                    aaa.id = 'id_' + i;
                    aaa.val = 0;
                    ddd.push(item);
                }

                $.each(ddd, function(index, obj) {
                    if (obj.id == 'id_7');
                    {
                        obj.val = 10;
                    }
                    alert(obj.val);
                });

办出应该只有一个10,但是现在输出都是10,是什么原因?

var ddd = new Array();
for (var i = 0; i < 10; i++) {
var aaa = new Object();
aaa.id = 'id_' + i;
aaa.val = 0;
ddd.push(aaa);
}

$.each(ddd, function(index, obj) {
if (obj.id == 'id_7'); { //这里多了个分号
obj.val = 10;
}
alert(obj.val);
});

有两处错误~~~

    <script type="text/javascript">
               var ddd = new Array();
                for (var i = 0; i < 10; i++) {
                    var aaa = new Object();
                    aaa.id = 'id_' + i;
                    aaa.val = 0;
                    ddd.push(aaa);   /// 把aaa写成item啦
                }

                $.each(ddd,function(index, obj) {
                    if (obj.id == 'id_7')  // 这里你多加了个分号，致命的错误
                    {
                        obj.val = 10;
                    }
                    alert(obj.val);
                });
    </script>
