    function ajaxFunction(){
    var ajaxRequest; // The variable that makes Ajax possible!

    try{
    // Opera 8.0+, Firefox, Safari
    ajaxRequest = new XMLHttpRequest();
    } catch (e){
    // Internet Explorer Browsers
    try{
    ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
    } catch (e) {
    try{
    ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
    } catch (e){
    // Something went wrong
    alert("Your browser broke!");
    return false;
    }
    }
    }
    return ajaxRequest;
    }
