If this most efficient

[EchoFool]

Hey,

 

I have an ajax script for a chat room but wanted some one who knows ajax to tell me if there is a way i can increase its efficientcy if at all...as it calls a php script all the time to check for new messages - was wondering if my method of calls can be improved?

 

Here is my script:

function createRequestObject() {
    var ro;
    var browser = navigator.appName;
    if(browser == "Microsoft Internet Explorer"){
        ro = new ActiveXObject("Microsoft.XMLHTTP");
    }else{
        ro = new XMLHttpRequest();
    }
    return ro;
}

var http = createRequestObject();

function sndReq() {
    http.open('get', 'chatcheck.php');
    http.onreadystatechange = handleResponse;
    http.send(null);
}

function handleResponse() {
    if(http.readyState == 4){
        var response = http.responseText;
        var update = new Array();
        if(response == '1') {
            updateShouts();
        }
    }
}

   
   
   
function sendMessage()
{
     $.ajax({
          type: "POST",
          url: "chatpost.php",
          async: false,
          data: "message="+$("#myMessage").val(),
        
      });
      $("#myMessage").val("");
      return false;
}



function updateShouts(){
    $('#chatArea').load('chat.php');
}
setInterval( "sndReq()", 1000 );

Your code is pretty mixed up, switching between vanilla Javascript and jQuery. Why?

Good question i just been googling and taking snippets here and there till it worked... is it sloppy design ?

 

Im no JS pro i just look on the net and copy what does till i get it to work. Where did i go wrong ?

Locked. There isn't a specific question, your asking for opinion. obviously know one has anything nice to say.
