Question

Is it possible to get information from URL without using the XmlHttpRequest .

I am trying to get document from my noSqlDatabase from URL
by the XHR object and It did not work . but If I type the URL in the browser I get the data.

Answer 1

If by ‘get information’ you mean load data from a 3rd party url without using XHR requests, the answer is yes, but with caveats.

One commonly used method to load json data cross-domain is called jsonp. Essentially, you define a function on your page:

var x = function(data){ //do something with data }

Then you create a script tag and append it to you page where the src attribute points to some other url that returns a js file like this:

x({ param: 'some data' });

The x function then executes on your page and has access to the ‘param’ data in the object. You can also pass a string or number using this method.

There is another method involving iframes and the window.name property of the iframe. This technique is a bit older but still works, but I won’t go into a lot of detail about it here.
