JQ Ajax can't make a request to get data in IE9 and below

Required plugin: https://github.com/MoonScript/jQuery-ajaxTransport-XDomainRequest

important point:

1. This script needs to be introduced after JQ, the core is to use XDomainRequest

2. Note that the webpage address and the API request address need to be the same http or https to be useful, otherwise IE will return an error warning that access is denied
