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
I'm executing script.js
from file1.html
, with js code:
var answers = JSON.parse('../../data/file.json');
alert(answers);
But it doesn't work, even alert is not starting. What is wrong?
Also I've tried this:
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.
This question is related to
javascript
jquery
json
parsing
Use something like this
$.getJSON("../../data/file.json", function(json) {
console.log(json); // this will show the info in firebug console
alert(json);
});
If Resources
is the root path, best way to access file.json
would be via /data/file.json
This solution uses an Asynchronous call. It will likely work better than a synchronous solution.
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);
}
}
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.
My case of working code is:
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);
