JSON 解析文件路径 [英] JSON Parse File Path

问题描述

我一直在尝试获取本地文件的正确路径.我有以下目录:

I'm stuck trying to get the correct path to the local file. I have the following directories:

Resources ->
   data ->
       file.json
   js ->
     folder ->
        script.js
   html ->
      folder ->
         file1.html

我正在使用 js 代码从 file1.html 执行 script.js:

I'm executing script.js from file1.html, with js code:

var answers = JSON.parse('../../data/file.json');
alert(answers);

但它不起作用，甚至警报也没有启动.怎么了?

But it doesn't work, even alert is not starting. What is wrong?

我也试过这个:

function readJSON(file) {
    var request = new XMLHttpRequest();
    request.open('GET', file, false);
    request.send(null);
    if (request.status == 200)
        return request.responseText;
};

var temp = readJSON('../../data/file.json');
alert(temp);

在这种情况下警报未定义.

Alert undefined in this case.

推荐答案

既然在data/目录下，你需要做的:

Since it is in the directory data/, You need to do:

文件路径为'../../data/file.json'

$.getJSON('../../data/file.json', function(data) {         
    alert(data);
});

纯JS:

   var request = new XMLHttpRequest();
   request.open("GET", "../../data/file.json", false);
   request.send(null)
   var my_JSON_object = JSON.parse(request.responseText);
   alert (my_JSON_object.result[0]);
