What you are looking for is called "pagination" and there's (as always) a jQuery plugin that does the job for you:

Edit: Since you don't seem to be able to get it working, here is one way (of several different) how you can use the plugin.

Step 1: Generate markup from your JSON-data like the following:

The idea is to copy the respective record to the display div when clicking on a page-link. Therefore, the plugin offers a pageSelect-callback function. Step 2 is to implement this function, for instance:

function pageselectCallback(pageIndex, jq){
    // Clone the record that should be displayed
    var newContent = $('#hiddenData div.record:eq('+pageIndex+')').clone();
    // Update the display container
    $('#display').empty().append(newContent);
    return false;
}

This would mean that you have one page per record. If you want to display multiple records per page, you have to modify the above function accordingly.

The third and final step is to initialize the whole thing correctly.

function initPagination() {
    // Hide the records... they shouldn't be displayed
    $("#hiddenData").css("display", "none");
    // Get the number of records
    var numEntries = $('#hiddenData div.result').length;
    // Create pagination element
    $("#pagination").pagination(numEntries, {
        num_edge_entries: 2,
        num_display_entries: 8, // number of page links displayed 
        callback: pageselectCallback,
        items_per_page: 1  // Adjust this value if you change the callback!
    });
}

So, you just have to generate the HTML markup from your JSON data and call the init-function afterwards.

It's not that difficult, is it?
