Question

How can I use javascript to send a one way message to php? I would like to get the browser information from javascript and just send it to php in the background. I know I can get some of this from php, but I’d rather use javascript. Is there a way to do this without a framework like jquery?

Yes, you can do it with something like this:

function xmlhttpPost(strURL) {
    var xmlHttpReq = false;
    var self = this;
    // Mozilla/Safari

    if (window.XMLHttpRequest) {
        self.xmlHttpReq = new XMLHttpRequest();
    } else if (window.ActiveXObject) {
       // IE
       self.xmlHttpReq = new ActiveXObject("Microsoft.XMLHTTP");
    }

    self.xmlHttpReq.open('POST', strURL, true);
    self.xmlHttpReq.onreadystatechange = function() {

        if (self.xmlHttpReq.readyState == 4) {
            alert('Here goes something');
            self.xmlHttpReq.send('browser info here');
        }
    }
} 

This will send “browser info here” as POST in the php page you pass to the function as url. I didnt test it though
