using ajax is very simple,
I recommend you to use HTML datatype for this as you have a table in your container,
there is an api documentation here => http://api.jquery.com/jQuery.ajax/
here's a fiddle I made for you => http://jsfiddle.net/sijav/kHtuQ/19/ or http://fiddle.jshell.net/sijav/kHtuQ/19/show/
I have put ajax code in a function named updateClass(url) which url stands for the url to get and it will append the container with the HTML it get =>
function updateClass(url){
$.ajax({
url: url,
dataType: "HTML",
error: function(msg){
alert(msg.statusText);
return msg;
},
success: function(html){
$("#container").html(html);
}
});
}
I have added a refreshClass which refresh the whole container class, =>
function refreshClass(){
updateClass("http://fiddle.jshell.net/sijav/mQB5E/5/show/"); //update the class
}
and changed on change selector to below code =>
var classUpdateI; //stands for our interval updating class
$(".class-selector").on("change",function(){
if (classUpdateI!=null)clearInterval(classUpdateI); //If the selector changed clear the interval so the container won't be update on it's own
if(this.value == "")
return; // if the value is null don't do anything
else if(this.value == "allclassnup"){
refreshClass(); //if the value is allclassnup which is stands for All Non-Updating just refresh the whole class
}
else if(this.value == "allclassup"){
refreshClass(); //if the value is allclassup which is stands for All Updating refresh the whole class and set an interval for thirty second (look for 30*1000)
classUpdateI = setInterval(refreshClass,30*1000);
}
else //else then it's a simple class value, just simply update the current class
updateClass(this.value);
})
Hope it helps ;)
EDIT: Edited so it can get big table (not generate it!) and all-updating will update in an interval of 30 sec
AnotherEDIT: Believe it or not I have done all of your question!
WORKING FIDDLE:http://jsfiddle.net/sijav/kHtuQ/39/ or http://fiddle.jshell.net/sijav/kHtuQ/39/show/
1 that is because it was only done for the last html, for the new we should make it again! so put the whole $('tr').click() function into another function and call it when necessary.
- do you want this to fully working? it's a little bit complicated but it can works with a bit of change in codes! that I'm gonna show you, Alright here's the algurithm we should put the current class on class selector change to cookie and then we can read it whenever we refresh or reload the page and put the necessary selected class and so on ...
but in code designing here I did to make it working,
first I made a global variable called FirstTimeInit = true; just to be sure if we're on the first time of page loading or not, second I put the for loop that make things highlighting on page load to a function called selectSelectedClass, why? because we need to call it many times, Third I added some if statement to be sure if we can read cookies then change highlighted things and current class also, here is the code:
if(readCookie("CurrentClass")) //if we can read coockie
$(".class-selector").val(readCookie("CurrentClass")).change(); //change it's value to current cookie and trigger the change function
else{ // else
selectSelectedClass(); //select those which was highlighted before
trClick(); //make things clickable
FirstTimeInit = false; //and turn of the first time init
}
Forth adding a create cookie on selector value changes = > createCookie("CurrentClass",$(".class-selector").val(),1);
and finally change the success on getting Ajax to this
success: function(html){
$("#container").html(html + '<a id="KEY"></a>'); //the html container changer with adding extra id , I'll explain it later it's for your second question
if(FirstTimeInit){ //if it is First Time then
selectSelectedClass(); //highlight which was highlighted after put the correct html
FirstTimeInit = false; // turn of the first time init
}
else //else
for (var i=0;i<($("table").children().length);i++){
if(readCookie(i))
eraseCookie(i); //erase every cookie that has been before because the table is now changed and we're going on another table so old cookie won't matter
}
trClick(); //make things selectable!
}
Also to make it bugfree I have changed the refreshClass to turn firstinit when the selected class is all or it is null because then we have all classes and need those cookies! so here's the code:
function refreshClass(){
if(readCookie("CurrentClass")=="allclassnup"||readCookie("CurrentClass")=="allclassup"||readCookie("CurrentClass")==null)
FirstTimeInit = true;
updateClass("http://fiddle.jshell.net/sijav/mQB5E/5/show/");
}
2 the <a id="TOP"></a> must be before the container, the <a id="KEY"></a> must be generated on the end of the container after putting html on the container. so $("#container").html(html + '<a id="KEY"></a>');
3 Next and Previous button was designed for non-ajax previous design, It's now needing a different solution! see these simple codes for example
$("#PreviousClass").click(function(){//on prev click
$(".class-selector").val($(".class-selector option:selected").prev().val()).change() //change the value to the prev on and trigger the change
});
$("#NextClass").click(function () {//on next click
$(".class-selector").val($(".class-selector option:selected").next().val()).change() //change the value to the prev on and trigger the change
});
4 Yes It is possible you should change your up to key and down to these codes and you're good to go =>
currentClass=0;
$("a.TOPJS").click(function () {
if(currentClass>0){
currentClass--
scrollToAnchor('CLASS'+currentClass);
}
});
$("a.KEYJS").click(function () {
if($("a[id='CLASS" + currentClass + "']")[0]!=undefined){
currentClass++
scrollToAnchor('CLASS'+currentClass);
}
else
scrollToAnchor('CLASSMAX');
});

Another Request EDIT: (hope this will be the last!)
Working Fiddle: http://jsfiddle.net/sijav/kHtuQ/42/ or http://fiddle.jshell.net/sijav/kHtuQ/42/show/
alright as you didn't like the change class on refresh to one which was in it I have removed that, and a better I have added some codes to have classes in cookies, as cookies are not tree there is some kind of conditions, the class is being read from the last character of class selector so be sure to have class number at the last character like -> Class number ***5*** the number 5 will be read for class selector!
EDIT: optimize class next and prev see http://jsfiddle.net/sijav/kHtuQ/46/
EDIT: As per comment requested,
That is what I'm trying to tell you, sometimes the demo shows on jsfiddle.net, sometimes it shows on fiddle.jshell.net, these are different domains and you cannot get html from different domains.
1) You may only put function in Interval or just create another function and call it proper way like this =>
classUpdateI = setInterval(function(){updateClass(this.value,parseInt(a.charAt(a.length-1),10));},30*1000);
2) Missings?! I can't find your second question!
3) Well, ... trclick needs to change ... to =>
function trClick(tIndex){ //tIndex would be classnumber from now on
if (tIndex == -1){ //if it is all updating or all non updating
$("tr").click(function(){ //do the previous do
$(this).toggleClass('selected').siblings().removeClass('selected');
if(readCookie($(this).parent().index("tbody"))){
if(readCookie($(this).parent().index("tbody"))==$(this).index())
eraseCookie($(this).parent().index("tbody"));
else{
eraseCookie($(this).parent().index("tbody"));
createCookie($(this).parent().index("tbody"),$(this).index(),1);
}
}
else
createCookie($(this).parent().index("tbody"),$(this).index(),1);
});
}
else{ //else
$("tr").click(function(){ //on click
$(this).toggleClass('selected').siblings().removeClass('selected');//do the toggle like before
if(readCookie(tIndex)){ //if you can read the CLASS cookie, not the current index of table because our table has only one row
if(readCookie(tIndex)==$(this).index()) //as before if we selecting it again
eraseCookie(tIndex); //just erase the cookie
else{ //else
eraseCookie(tIndex); //select the new one
createCookie(tIndex,$(this).index(),1);
}
}
else
createCookie(tIndex,$(this).index(),1); //else if we can't read it, just make it!
});
}
}
and when we call it on Ajax success we should call it with classNumber => trClick(classNumber);
