php - How could I send the information in AJAX at POST? -

sorry english...

how send information that's in ajax post? (info, info_1, info_2)

now, i'm sending get

edit: try people here said me do, when call post variable in page send him info, show me eror... why?

the new code:

var xhr = new xmlhttprequest(); xhr.open("post",url,true); xhr.onreadystatechange = function() {     if( this.readystate == 4 && this.status == 200) {         document.getelementbyid(name).innerhtml = this.responsetext;     } }; xhr.send("info="+str+"&info_1="+info_1+"&info_2="+info_2); return false;

the first code:

var xhr = new xmlhttprequest(); xhr.open("get",url+"?info="+str+"&info_1="+info_1+"&info_2="+info_2,true); xhr.onreadystatechange = function() {     if( this.readystate == 4 && this.status == 200) {         document.getelementbyid(name).innerhtml = this.responsetext;     } }; xhr.send(); return false; 

change "get" "post" , put data (in same form in query string, without ? prefix) argument send() method instead of in url.
