In general, if you don't know how something works, look for an example which you can learn from.
For this problem, consider this DEMO
You can see loading content with AJAX is very easily accomplished with jQuery:
$(function(){
// don't cache ajax or content won't be fresh
$.ajaxSetup ({
cache: false
});
var ajax_load = "<img src='http://automobiles.honda.com/images/current-offers/small-loading.gif' alt='loading...' />";
// load() functions
var loadUrl = "http://fiddle.jshell.net/deborah/pkmvD/show/";
$("#loadbasic").click(function(){
$("#result").html(ajax_load).load(loadUrl);
});
// end
});
Try to understand how this works and then try replicating it. Good luck.
You can find the corresponding tutorial HERE
Right now the following event starts the ajax load function:
$("#loadbasic").click(function(){
$("#result").html(ajax_load).load(loadUrl);
});
You can also do this periodically: How to fire AJAX request Periodically?
(function worker() {
$.ajax({
url: 'ajax/test.html',
success: function(data) {
$('.result').html(data);
},
complete: function() {
// Schedule the next request when the current one's complete
setTimeout(worker, 5000);
}
});
})();
I made a demo of this implementation for you HERE. In this demo, every 2 seconds (setTimeout(worker, 2000);) the content is updated.
You can also just load the data immediately:
$("#result").html(ajax_load).load(loadUrl);
Which has THIS corresponding demo.
