JSON Parse File Path
提问by jagger
I'm stuck trying to get the correct path to the local file. I have the following directories:
我一直在尝试获取本地文件的正确路径。我有以下目录：
Resources ->
data ->
file.json
js ->
folder ->
script.js
html ->
folder ->
file1.html
I'm executing script.jsfrom file1.html, with js code:
我script.js从file1.html,执行js 代码：
var answers = JSON.parse('../../data/file.json');
alert(answers);
But it doesn't work, even alert is not starting. What is wrong?
但它不起作用，甚至警报也没有启动。怎么了？
Also I've tried this:
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);
Alert undefined in this case.
在这种情况下警报未定义。

Since it is in the directory data/, You need to do:
由于它在目录中data/，您需要执行以下操作：
file path is '../../data/file.json'
文件路径是 '../../data/file.json'
$.getJSON('../../data/file.json', function(data) {
alert(data);
});
Pure JS:
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]);

This solution uses an Asynchronous call. It will likely work better than a synchronous solution.
此解决方案使用异步调用。它可能比同步解决方案更有效。
var request = new XMLHttpRequest();
request.open("GET", "../../data/file.json", false);
request.send(null);
request.onreadystatechange = function() {
if ( request.readyState === 4 && request.status === 200 ) {
var my_JSON_object = JSON.parse(request.responseText);
console.log(my_JSON_object);
}
}

Use something like this
使用这样的东西
$.getJSON("../../data/file.json", function(json) {
console.log(json); // this will show the info in firebug console
alert(json);
});

var request = new XMLHttpRequest();
request.open("GET","<path_to_file>", false);
request.send(null);
var jsonData = JSON.parse(request.responseText);
This code worked for me.
这段代码对我有用。

My case of working code is:
我的工作代码案例是：
var request = new XMLHttpRequest();
request.open("GET", "<path_to_file>", false);
request.overrideMimeType("application/json");
request.send(null);
var jsonData = JSON.parse(request.responseText);
console.log(jsonData);

If Resourcesis the root path, best way to access file.jsonwould be via /data/file.json
如果Resources是根路径，最好的访问file.json方式是通过/data/file.json
