    Question Dynamic Ajax Content - after refresh

    1) Script Title: Dynamic Ajax Content

    2) Script URL (on DD):

    3) Describe problem: after refresh, page loaded through AJAX disappear. Is there a way I can retain the latest loaded page?


    I also tried something from here :

    both does not work... What happens is I got stuck on the latest loaded page.

    Thank you in advance.

    If you only have one DIV container on the page that's loading Ajax content into, getting the script to recall the last viewed content automatically when the page loads is very simple. Take a look at the following code, with the changes to the default script highlighted in red:

    <script type="text/javascript">

    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){
    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){
    page_request = new ActiveXObject("Microsoft.XMLHTTP")
    catch (e){}
    return false
    document.cookie = "lastloadedfile=" + url
    loadpage(page_request, containerid)
    if (bustcachevar) //if bust caching of external page
    bustcacheparameter=(url.indexOf("?")!=-1)? "&"+new Date().getTime() : "?"+new Date().getTime()'GET', url+bustcacheparameter, true)
    function loadpage(page_request, containerid){
    if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
    function loadobjs(){
    if (!document.getElementById)
    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.setAttribute("src", file);
    else if (file.indexOf(".css")!=-1){ //If object is a css file
    fileref.setAttribute("rel", "stylesheet");
    fileref.setAttribute("type", "text/css");
    fileref.setAttribute("href", file);
    if (fileref!=""){
    loadedobjects+=file+" " //Remember this object as being already added to page
    var lastloadedfile = (function(name){
    	var re=new RegExp(name+"=[^;]+", "i"); //construct RE to search for target name/value pair
    	if (document.cookie.match(re)) //if cookie found
    		return document.cookie.match(re)[0].split("=")[1] //return its value
    	return null
    }) ('lastloadedfile')
    if (window.addEventListener && lastloadedfile)
    	window.addEventListener('load', function(){ajaxpage(lastloadedfile, 'contentarea');}, false)
    else if (window.attachEvent && lastloadedfile)
    	window.attachEvent('onload', function(){ajaxpage(lastloadedfile, 'contentarea');})
    <a href="javascript:ajaxpage('test.htm', 'contentarea');">test</a> | <a href="javascript:ajaxpage('test2.htm', 'contentarea');">test</a>
    <div id="contentarea"></div>
    <a href="javascript:ajaxpage('test.htm', 'contentarea');">test</a> | <a href="javascript:ajaxpage('test2.htm', 'contentarea');">test 2</a>
    <div id="contentarea"></div>

    The above code assumes your DIV Ajax container has an ID of "contentarea"; if not, inside the code in red, change the words "contentarea" to the actual DIV ID. With the above changes, clicking on "test1" to load test.htm then reloading the page will automatically recall "test.htm", populated inside the "contentarea" DIV. Same with the "test2" link.
