如何从JSON数组中检索特定数据？

Question

下面是输出的Json数组。我想从这个数组中只检索名称和描述。我希望结果进入HTML页面中的表。 请帮帮我。

Answer 1

要在JSON中访问您想要的任何元素，您必须循环使用它。

假设您有一个名为 tasks_details

的对象

    var tasks_details = your_array['tasks'],
        tasks_no = tasks_details.length;
    for (var i = 0; i < tasks_no; i++)
    {
       $('.your_table').append('<tr><td>' + tasks_details[i].name + '</td>\
 <td>' + tasks_details[i].description + '</td></tr>');
    }

示例代码与之前一样，现在可以选择如何填写表格。
