Question

我从网络服务获取以下JSON字符串。

[{"TITLE":"asdasdasd","DESCRIPTION":"asdasd","PORTFOLIOID":1},
 {"TITLE":"sss","DESCRIPTION":"sss","PORTFOLIOID":2},
 {"TITLE":"sdfsdf","DESCRIPTION":"sdfsfsdf","PORTFOLIOID":3}]

我可以在jquery中循环遍历此数组并输出单个键/值对吗？

Answer 1

var a = [{"TITLE":"asdasdasd","DESCRIPTION":"asdasd","PORTFOLIOID":1}, ....]

$(a).each(function(index)
{
   //this is the object in the array, index is the index of the object in the array
   alert(this.TITLE + ' ' this.DESCRIPTION)
});

Answer 2

绝对。假设您告诉jQuery使用AJAX方法将此响应评估为JSON，您只需执行此操作：

<script>
$(data).each(function(idx, obj) //this loops the array
{
    $(obj).each(function(key, value) //this loops the attributes of the object
    {
        console.log(key + ": " + value);
    }
}
</script>

Jquery，循环遍历json数组
