Parse.com error with document.createElement('script')

Question

I'm trying to use this code with Parse.Cloud.beforeSave...

var script = document.createElement('script');

and I get this: Result: ReferenceError: document is not defined

How can I use document with Parse.Cloud?

My code:

function getJSONP(url, success) {
        var script = document.createElement('script');
        script.src = url.replace('callback=', 'callback=do');
        document.head.appendChild(script);

        do = function (data) {
            success(data);
        }
 }

Parse Cloud code does not run in the browser. It runs on the server where the DOM does not exist. Why are you trying to use the DOM? — Felix Kling

I'm trying to download a JSONP... function getJSONP(url, success) { var script = document.createElement('script'); script.src = url.replace('callback=', 'callback=do'); document.head.appendChild(script); do = function (data) { console.log(data); success(data); } } — Geek20

Not sure if Parse allows it, but you could just make a normal HTTP request and eval the response. JSONP is only used to circumvent the same-origin policy in the browser. There is no need for script tags on the server side, just make the HTTP request. — Felix Kling

I wonder if you can somehow use jsdom on Parse.com? Alternatively, does this question and answer help? — Ken Y-N

Thanks! @FelixKling the solution is Parse.Cloud.httpRequest. — Geek20

The solution:

Parse.Cloud.httpRequest({
    url: myURL,
    success: function(httpResponse) {
        console.log(httpResponse.data);
        response.success();
    }, error: function(httpResponse) {
        response.error('Request failed...');
     }
});
