A brief section of JSONP Callback code

Defines the global callback function and writes the timestamp parameter as the method name in the window. Here, my format is jsonp + timestamp. The same timestamp parameter can be used for sending requests and executing callback functions.

/**
* Remote Data Loading
* @ Method loader
* @ Param {String} o parameter configuration
*/
Function loader (o ){

Var timestamp = 'jsonp' + new Date (). getTime ();

// Define the global callback function
Window [timestamp] = function (data ){

// Execute the callback function in the Configuration Parameter
O. callback (data );

}

// Read remote JSONP data
KISSY. getScript (o. url + timestamp );

} When loading, call the loader method:

Loader ({
Url: 'http: // ooxx.html? Callback = ',
Callback: function (data ){
Console. log (data );
}
})
