more options

Dear Sirs,

I need to use synchronous Ajax call which breaks on opening in synchronous mode. The error is NS_ERROR_FAILURE. This code works perfectly in IE, Chrome and Safari. Please help. Regards, Mark

Here I included part of my code.

function PostRequest(MyUrl){

 var qXML = new XMLHttpRequest();

// some code
 
  qXML.open("POST", MyUrl, false);
  qXML.setRequestHeader('Accept', '*');
  qXML.setRequestHeader('Origin', '*');
  qXML.setRequestHeader('content-type','application/x-www-form-urlencoded');
        try {
         qXML.send(StringToPost);
     
// some code .....        

        } catch(err){
         alert(err + '\n...unavailable.\nYour request will appear in the new window.');
                 }; // post log

Sorry, this forum is for Firefox user support, there may not be any Ajax developers providing support here this morning.

Try posting at the Web Development / Standards Evangelism forum at MozillaZine. The helpers over there are more knowledgeable about web page development issues with Firefox.
