javascript - Make a YUI asyncRequest call which is not async -

-

i want make yahoo.util.connect.asyncrequest call, not async. open(method, url, async) false passed async.

i can't find "syncrequest" in connect class. possible using yui 2?

i tried without yui instead:

function createrequestobject() {     var ro;     // mozilla, safari,...     if (window.xmlhttprequest) {         ro = new xmlhttprequest();         if (ro.overridemimetype) {             ro.overridemimetype('text/xml');             // see note below line         }         // ie     } else if (window.activexobject) {         try {             ro = new activexobject("msxml2.xmlhttp");         } catch (e) {             try {                 ro = new activexobject("microsoft.xmlhttp");             } catch (e) {}         }     }     if (!ro) {         alert('giving :( cannot create xmlhttp instance');         return false;     }     return ro; } function sndreq(param,server,handler) {     http = createrequestobject();     http.open('get', server+"?"+param, false);     http.setrequestheader('content-type','application/x-www-form-urlencoded');     http.onreadystatechange = handler;     http.send(null); }

but in firefox , safari callback function (handler) not called on 'onreadystatechange' when false passed in 'open'? in ie , opera works ok.

yui3 supports synchronous requests in "yui io" , available on development master on github. implementation syntax included in readme file, , formally documented release in 3.1.0. enhancement documented 2528181 on yuilibrary.com.

if in position use yui 3, give io try.
