if you should have quick loading times which prevent te loading showing, you can add a timeout of some sort.

Let's say you have a tag someplace on the page which contains your loading message:

<div id='loadingmessage' style='display:none'>
  <img src='loadinggraphic.gif'/>
</div>

You can add two lines to your ajax call:

function getData(p){
    var page=p;
    $('#loadingmessage').show();  // show the loading message.
    $.ajax({
        url: "loadData.php?id=<? echo $id; ?>",
        type: "POST",
        cache: false,
        data: "&page="+ page,
        success : function(html){
            $(".content").html(html);
            $('#loadingmessage').hide(); // hide the loading message
        }
    });

Answer 5

<div id="load" style="display:none"><img src="ajax-loader.gif"/></div>

function getData(p){
        var page=p;
        document.getElementById("load").style.display = "block";  // show the loading message.
        $.ajax({
            url: "loadData.php?id=<? echo $id; ?>",
            type: "POST",
            cache: false,
            data: "&page="+ page,
            success : function(html){
                $(".content").html(html);
        document.getElementById("load").style.display = "none";
            }
        });

//$(document).ready(function(){
//	 $("a").click(function(event){
//		event.preventDefault();
//		$("div").html("This is prevent link...");
//	});
//});			

$(document).ready(function(){
	$("a").click(function(event){
		event.preventDefault();
		$.ajax({
			beforeSend: function(){
				$('#text').html("<img src='ajax-loader.gif' /> Loading...");
			},
			success : function(){
				setInterval(function(){ $('#text').load("cd_catalog.txt"); },1000);
			}
		});
	});
});
