如何从一个JSON文件中的数据？ [英] How to get data from a json file?

问题描述

我一直在尝试使用JSON和Ajax使用jQuery，我在一些麻烦运行。我想从一个JSON文件中的数据，以显示在我的网页。

I have been trying to use json and ajax with jquery and I am running in to some trouble. I am trying to get data from a json file to display on my page.

目前，我只是想将其发送到控制台，但是我得到空的控制台。我不知道我在做什么对，什么我做错了，所以我只是想知道如果我能得到一些指引。

At the moment I am just trying to send it to the console but I am getting null in the console. I am not sure what I am doing right and what I am doing wrong so I was just wondering if I could get some pointers.

这是我的请求

$(document).ready(function() {
var json = (function () {
var json = null;
$.ajax({
    'async': false,
    'global': false,
    'url': 'js/refs.json',
    'dataType': "json",
    'success': function (refs) {
        json = refs;
    }
});
return json;
})(); 
console.log(json);

这是什么在refs.json

This is what is in refs.json

var refs = {
"referee": [
        {
            "name": "Ellie",

                }
            ],
            "docs": [
                {
                    "type": "doc",

                    "size" :"223KB",
                },
                {
                    "type": "pdf",
                    "links": "nio.pdf",
                    "size" :"943.KB",
                }
                ],

            "grade": "Not yet awarded",
            "sshot": "nio1.png"
        }
    ]
};

正如我说的，使用的console.log控制台响应为空。我看不到我要去的地方对还是错。该请求是一个片段，我从一个岗位上了这里（负荷JSON成可变）

任何指针将是非常美联社preciated

Any pointers would be much appreciated

在此先感谢

推荐答案

您的文件不是JSON！

Your file is not JSON!

它开始与 VAR裁判= ....

Suprress分配（和尾随分号）。

Suprress the assignment (and trailing semicolon).

（如果你真懒，复制/粘贴什么应该是从@ MikeB的答复文件中）

(if you are really lazy, copy/paste what should be in the file from @MikeB's answer)
