<script type="text/javascript">

    // unblock when ajax activity stops
    $().ajaxStop($.unblockUI);

    function test() {
        $.ajax({ url: ‘wait.php‘, cache: false });
    }

    $(document).ready(function() {
        $(‘#pageDemo1‘).click(function() {
            $.blockUI();
            test();
        });
        $(‘#pageDemo2‘).click(function() {
            $.blockUI({ message: ‘<h1><img src="busy.gif" /> 请稍后...</h1>‘ });
            test();
        });
        $(‘#pageDemo3‘).click(function() {
            $.blockUI({ css: { backgroundColor: ‘#f00‘, color: ‘#fff‘ } });
            test();
        });

        $(‘#pageDemo4‘).click(function() {
            $.blockUI({ message: $(‘#domMessage‘) });
