jQuery.getJSON equivalent in MooTools - ajax

Question

Is there any jQuery.getJSON() equivalent in MooTools? I have a json file named data.json and I want to get its content by calling data.json file using MooTool. Is it possible? I tried Request.JSON() method but it didn't work for me. The below is my code,
var json_req = new Request.JSON({
url:'../public_html/data/data.json',
method: 'get',
secure: true,
data:{
json: true
},
onSuccess: function (res){
this.result = res;
},
onFailure: function(){
this.result = "failed";
}
}).send();
Also from the http://demos111.mootools.net/ I found an Ajax class named Ajax() which they are widely using through out their tutorial. But in MooTools documentation I didn't find this Ajax() class. I tried to use the Ajax() by replacing my Request.JSON(), but got an "Ajax not defined" error. What is this Ajax class and how can we use it in MooTools?

Answer 1

Here is a simple example of the functionality you are looking after. Basically wrapping a function around the Class... you could use the Class directly also.
function getJSON(url, callback) {
new Request.JSON({
url: url,
onSuccess: callback
}).send();
}
// and invoque it:
getJSON('/echo/json/', function(json) {
console.log(json);
});
you can check it live here: https://jsfiddle.net/w64vo2vm/

This one works for me
window.addEvent('domready', function() {
new Request.JSON({
url: url,
data: {'delay': 1},
method: 'post',
onSuccess: function(response) {
var myJSON = JSON.encode(response)
console.log(myJSON);
}
}).send();
})

I have a small function for this task. Here's the code
var configJson;
function klak_readJson(fileurl) {
var myRequest = new Request({
url: fileurl,
method: 'get',
onRequest: function(){
console.log('loading '+fileurl+'...');
},
onSuccess: function(responseText) {
console.log('received bytes '+responseText.length);
configJson=JSON.parse(myRequest.response.text);
}
});
myRequest.send();
}
Call the function to store the JSON object into configJson
klak_readJson('/js/test.json');
Hope it helps.
