使用$ .getScript回调函数加载脚本

Question

I'm loading the Google Maps API using jquery $.getScript like so

$.getScript("https://maps.googleapis.com/maps/api/js?async=2&callback=GMapsInit");

You can see that the URL has the callback function GMapsInit . Does the GMapsInit function get called after the script is loaded and executed, or simply after its loaded and not necessarily executed?

Answer 1

The callback is called when the script is loaded AND executed.

This is why you have to use a callback when you load Google Maps.
