This lines may help you with your idea
First insert this js functions next to yours
function readFile(file, callback) {
var rawFile = new XMLHttpRequest();
rawFile.overrideMimeType("application/json");
rawFile.open("GET", file, true);
rawFile.onreadystatechange = function() {
if (rawFile.readyState === 4 && rawFile.status === 200) {
callback(rawFile.responseText);
}
}
rawFile.send(null);
}
function getCookie(cname) {
var name = cname + "=";
var decodedCookie = decodeURIComponent(document.cookie);
var ca = decodedCookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
Then like you says about the language cookie you can use this js line :
var dataJSON;
readFile("content/languages/"+getCookie("language")+".json", function(text) {
dataJSON = JSON.parse(text);
});
the results is like that content/languages/english.json if you have english value inside language cookie
The easy part comes next, if your json objects is like that
{
"test": {
"test1" : "test2",
}
}
You can just write dataJSON.test.test1 to print test2
