jQuery JSONP cross-domain practice

First on the js code:

dataType
Type: String
The type of data returned by the expected server. If not specified, jQuery will automatically make intelligent judgments based on the MIME information of the HTTP packet, such as XML MIME type is recognized as XML. In 1.4, JSON generates a JavaScript object, and the script executes the script. The data returned by the server is then parsed according to this value and passed to the callback function. Available values:
•"xml": Returns an XML document that can be processed with jQuery.
•"html": Returns plain text HTML information; The included script tag is executed when the DOM is inserted.
•"script": Returns plain text JavaScript code. Results are not automatically cached. Unless the "cache" parameter is set. Note: On remote requests (not under the same domain), all POST requests will be turned into GET requests. (because the DOM's script tag will be used to load)
•"json": Returns JSON data.
•"jsonp": JSONP format. When calling a function in JSONP form, e.g. "myurl?callback=?" jQuery will automatically replace ? is the correct function name to execute the callback function.
•"text": Returns a plain text string
