Remote call returning undefined

[travisbrown]

I'm trying to return a remote call to an alert. Does the code below look correct? I'm getting 'undefined'.

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

function getString(page) {
    var http = createRequestObject();
    http.open( 'get', page , true);
    http.onreadystatechange = function(){
         if ( http.readyState == 4 ) {
        var response = http.responseText;
        return response;
        http = null;
        }    
    };
    http.send(null);
}

alert(getString('mypage.asp'));

The remote page is returning a string value when I run it in isolation.

I couldn't be certain about this, but try:

http.onreadystatechange = function([!]callBackData[/!]){
         if ( http.readyState == 4 ) {
        var response = [!]callBackData[/!].responseText;
        return response;
        http = null;
        }    
    };

Failing that, try asking in forum1600.

Hope this helps,
Dan

Thanks Dan. I couldn't get it to work, so posted in AJAX forum. Monksnake figured it out here:
