如何从其他域获取json数据？

Question

I want to use the google images api. In the past when I worked with json I simply used the ajax function to get the json from my own server. But now I will be getting it from an external domain:

https://ajax.googleapis.com/ajax/services/search/images?q=fuzzy monkey&v=1.0

Obviously I can't load this using js since its not from an internal url. So in these cases how does one work with json data. Are you supposed to load it via CURL using a server side script or is there another way?

Answer 1

You can make use of JSONP by adding a callback GET param.

https://ajax.googleapis.com/ajax/services/search/images?q=fuzzy%20monkey&v=1.0&callback=hello

Then you can request it with jQuery's $.getJSON().

$.getJSON('https://ajax.googleapis.com/ajax/services/search/images?q=fuzzy%20monkey&v=1.0&callback=?', function(response) {
    console.log(response.responseData);
});

jsFiddle.
