    Question SOLVED! Focus on element loaded in content via AJAX?

    I use this AJAX JavaScript...
    http://www.dynamicdrive.com/dynamici...jaxcontent.htm

    Before AJAX event...
    <div id="loadajaxhere"></div>
    After AJAX event...
    <div id="loadajaxhere">
    <div><a href="#" id="give_focus">example</a></div>
    </div>
    I want to give give_focus focus but I can't by default. I presume JavaScript needs a swift kick to wake up and realize new content has been added?

    Cool

    AJAX Function
    ajaxpage(path + 'includes/ajax_content.php', 'id_target','focus_element');
    Modified AJAX JavaScript adding focus support!
    var bustcachevar=1 //bust potential caching of external pages after initial request? (1=yes, 0=no)
    var loadedobjects=""
    var rootdomain="http://"+window.location.hostname
    var bustcacheparameter=""

    function ajaxpage(url, containerid,givefocus){
    var page_request = false
    if (window.XMLHttpRequest) // if Mozilla, Safari etc
    page_request = new XMLHttpRequest()
    else if (window.ActiveXObject){ // if IE
    try {
    page_request = new ActiveXObject("Msxml2.XMLHTTP")
    }
    catch (e){
    try{
    page_request = new ActiveXObject("Microsoft.XMLHTTP")
    }
    catch (e){}
    }
    }
    else
    return false
    page_request.onreadystatechange=function(){
    loadpage(page_request, containerid,givefocus)
    }
    if (bustcachevar) //if bust caching of external page
    bustcacheparameter=(url.indexOf("?")!=-1)? "&"+new Date().getTime() : "?"+new Date().getTime()
    page_request.open('GET', url+bustcacheparameter, true)
    page_request.send(null)
    }

    function loadpage(page_request, containerid,givefocus){
    if (page_request.readyState == 4 && (page_request.status==200 window.location.href.indexOf("http")==-1))
    document.getElementById(containerid).innerHTML=page_request.responseText;

    document.getElementById(givefocus).focus();
    }

    function loadobjs(){
    if (!document.getElementById)
    return
    for (i=0; i<arguments.length; i++){
    var file=arguments[i]
    var fileref=""
    if (loadedobjects.indexOf(file)==-1){ //Check to see if this object has not already been added to page before proceeding
    if (file.indexOf(".js")!=-1){ //If object is a js file
    fileref=document.createElement('script')
    fileref.setAttribute("type","text/javascript");
    fileref.setAttribute("src", file);
    }
    else if (file.indexOf(".css")!=-1){ //If object is a css file
    fileref=document.createElement("link")
    fileref.setAttribute("rel", "stylesheet");
    fileref.setAttribute("type", "text/css");
    fileref.setAttribute("href", file);
    }
    }
    if (fileref!=""){
    document.getElementsByTagName("head").item(0).appendChild(fileref)
    loadedobjects+=file+" " //Remember this object as being already added to page
    }
    }
    }
