Ajax sends a POST request

 

// Create an Ajax object (compatible with processing) function createxhr () {var xhr = NULL; If (window. XMLHttpRequest) {xhr = new XMLHttpRequest ();} else if (window. activexobject) {xhr = new activexobject ('Microsoft. XMLHTTP ');} return xhr;} // send the POST Request function request () {xhr. open ('post', 'checkrequire. php', true); xhr. setRequestHeader ("Content-Type", "application/X-WWW-form-urlencoded"); // This line must be added for post requests, and xhr is not required for GET requests. onreadystatechange = function () {If (this. readystate = 4 & this. status = 200) {alert (this. responsetex); // return the data and process it} xhr. send ('name = Tom & age = 20'); // send request data, GET request xhr. send (null );}
