尝试使用jQuery解析JSON文件 [英] Trying to parse JSON file with jQuery

问题描述

我正在尝试使用下面的确切结构来解析JSON文件.

I am trying to parse a JSON file with the exact stucture as in the following.

{
    "students": {
        "student": [
            {
                "id": 1,
                "name": "John Doe",
                "image": "pic1.jpg",
                "homepage": "http: //www.google.com"
            },
            {
                "id": 2,
                "name": "Jane Doe",
                "image": "pic1.jpg",
                "homepage": "http: //www.google.com"
            }
        ]
    }
}

我正在使用以下jQuery函数:

I am using the following jQuery function:

function GetStudents(filename)
{
    $.getJSON(filename, function(data){
        $.each(data.student, function(i,s){
            var id = s.id;;
            var name = s.name;;
            var img = s.image;;
            var homepage = s.homepage;
            $('.networkTable').append('<tr><td><img src="' + img + '" class="picEven pic" width="33" height="35"></td><td><a href="'+ homepage + '" class="networkLink">' + name + '</a></td></tr>');
        });
    });
}

我在做错什么吗?

推荐答案

您没有访问正确的元素. data不指向students，它指向最外面的元素{students:...}(students是它的一个属性).数组包含在data.students.student:

You are not accessing the correct element. data does not point to students, it points to the outer most element {students:...} (students is an property of it). The array is contained in data.students.student:

$.each(data.students.student, function() {
    //...
});

Further notes:

• 如果只访问一次属性，则无需创建局部变量(但当然，它可能更易读).

• You don't need to create a local variable if you access a property only once (but of course it might be more readable).

具有连续的分号;;并没有错，但这是不必要且令人困惑的(至少使我感到困惑；))

While having consecutive semicolons ;; is not wrong, it is unnecessary and confusing (at least it confuses me ;))
