FR.ajax

value must be Key/Value format, which can be a string such as p1=pavalue&p2=p2value, or an object such as {p1:p1value,p2:p2value}

The expected data type returned by the server. If not specified, it will be automatically judged intelligently according to the MIME information of the HTTP packet. Available values are:

"xml": Returns an XML document
"html": Returns plain-text HTML information; the included script tags are executed when inserted into the dom.
"script": Returns plain text JavaScript code.
"json": Returns JSON data.
"text": Returns a plain text string.
"jsonp" : use jsonp across domains

The callback function after the request is successful, the format is as follows:

success: function(data, textStatus){  
// data is returned by the server and processed according
 to the dataType parameter.
//textStatus is the status value success
}

The following example:

FR.ajax({
	url: "/webapps/webroot/a.html",
	success: function(data, textStatus) {
		alert(this.url);
	}
});

This function is called when the request fails, in the format:

error: function(XMLHttpRequest, textStatus, errorThrown){ 
//The parameters are the XMLHttpRequest object, the error message, and the captured exception object.// Usually only one of textStatus and errorThrown will
 contain information
 }

The following example:

FR.ajax({
	url: "some.jsp",
	error: function(XMLHttpRequest, textStatus, errorThrown) {
		alert(this.url);
	}
});

complete: function(XMLHttpRequest, textStatus){  
//The parameters are the XMLHttpRequest object and 
a string describing whether the successful request was successful or not.
 }

The following example:

FR.ajax({
	url: "some.jsp",
	complete: function(XMLHttpRequest, textStatus) {
		alert(this.url);
	}
});

The default is true, all requests are asynchronous requests. Set this option to false if you need to send synchronous requests.

Note: A synchronous request will lock the browser, and the user must wait for the request to complete before performing other operations.
