Jquery. Get (URL, [data], [callback], [type])
Load information through remote http get requests
Parameter --
URL: the requested URL.
Data: Key/value parameter to be sent.
Callback: callback function when the load is successful.
Type: The returned content format is XML, HTML, script, JSON, text, and _ default.
The get () method provides the callback function, which has three parameters: responsetext, textstatus, and XMLHttpRequest, which respectively represent the content, Request status, and XMLHttpRequest objects returned by the request.
$. Get ("Data/getserviceinfo. aspx ", function (responsetext, textstatus, XMLHttpRequest) {// responsetext: Content returned by the request // textstatus: Request status: Success, error, notmodified, timeout // XMLHttpRequest: XMLHTTPRequest object });
Datatype specifies the expected server response data type. By default, jquery performs intelligent judgment. Possible types: "XML" "html" "text" "script" "JSON" "jsonp"
The biggest difference between jquery. Post and jquery. get is that the former loads information through remote http post requests. The latter loads information through a remote http get request. The other parts are basically the same.

Add:
Compare load and get:
$. Load () is the simplest way to get data from the server. It is almost equivalent to $. Get (). The difference is that it is not a global function and it has an implicit callback function. When a response is detected successfully (for example, when textstatus is "success" or "notmodified"), $. Load () sets the HTML content of the matching element to the returned data.
This is why $ ("# result"). Load () is used in the previous instance (). In this example, $. Get () is used ()
