External API GET() Request Using JQuery
Solution 1:
Replace:
$.ajax({
type: "GET",
url: "http://www.imdbapi.com/",
cache: false,
data: dataString,
success: function(html){
//$("#more").after(html);
alert("Success!");
}
});
With
$.getJSON('http://www.imdbapi.com/?' + dataString, function(json_data){
alert(JSON.stringify(json_data));
});
Solution 2:
It is a cross domain AJAX call, therefore you need a callback. jQuery makes this really easy, just add ?callback=?
to your url.
url: "http://www.imdbapi.com/?" + dataString + "&callback=?"
Skip the data = dataString
in this case, makes it easier (I find).
Try this, and continue on it further:
$.getJSON("http://www.imdbapi.com/?" + dataString + "&callback=?").success(function(data){
console.log(data); // will contain all data (and display it in console)
})
This is the same as:
$.ajax({
type: "GET",
url: "http://www.imdbapi.com/?"+dataString+"&callback=?",
dataType: 'JSONP'
success: function(data){
console.log(data);
}
Solution 3:
You can run cross domain Ajax with jQuery. Set the crossDomain
option at the call site:
http://api.jquery.com/jQuery.ajax/
crossDomain(added 1.5)Boolean Default: false for same-domain requests, true for cross-domain requests If you wish to force a crossDomain request (such as JSONP) on the same domain, set the value of crossDomain to true
Edit-
Actually, what exactly is your problem? I tried this and it returns Json properly.

Solution 4:
Add a callback
parameter to the URL to use JSONP:
dataString = "t=Avatar&callback=?";
Using a $
will cause jQuery to auto-generate a callback function for you and handle the response automatically.
