AJAX Request Help for next/previous page

Question

How do I use AJAX to get the Next/Previous Page(s).

How to call in a browser:

page.php?page=1-1

or

page.php?page=1
         


        

Answer 1

Try something like this... Keep a global variable called currentPage and simply adjust the page number accordingly.

HTML

<input id="next" type="button" value="Next" />
<input id="prev" type="button" value="Previous" /> 
<div id="displayResults" name="displayResults">Current Page: 1</div>

JS

var currentPage=1;
loadCurrentPage();

$("#next, #prev").click(function(){
    currentPage = 
        ($(this).attr('id')=='next') ? currentPage + 1 : currentPage - 1;

    if (currentPage==0) //Check for min
        currentPage=1;
    else if (currentPage==101) //Check for max
        currentPage=100;
    else
        loadCurrentPage();
});

function loadCurrentPage(){
    $('input').attr('disabled','disabled'); //disable buttons

    //show loading image
    $('#displayResults').html('<img src="http://blog-well.com/wp-content/uploads/2007/06/indicator-big-2.gif" />'); 

    $.ajax({
        url: '/echo/html/',
        data: 'html=Current Page: ' + currentPage+'&delay=1',
        type: 'POST',
        success: function (data) {
            $('input').attr('disabled',''); //re-enable buttons
            $('#displayResults').html(data); //Update Div
        }
    });
}

Then your php page can access $_REQUEST['page']; and return data accordingly.
