JQuery - 停止点击标记

I have the following code:

我有以下代码:

//------------------------------------------------------//
// When the document is ready, start firing our AJAX    //
//------------------------------------------------------//
$(document).ready(function() {
    $("#navIndex a").click(function() {
        this.blur();
        return false;
    });
    $("#navPrevNext a").click(function() {
        this.blur();
        return false;
    });

    // Bind actions...
    $("#navIndex a").click(function(e) { e.preventDefault; updateNavigation($(this).attr('href')); });
    $("#navPrevNext a").click(function(e) { e.preventDefault; updateNavigation($(this).attr('href')); });
(); });
});

//--------------------------------------------------------------------------//
// METHODS - Get the params from the page and execute a server side call    //
//--------------------------------------------------------------------------//
function updateNavigation(pageIndex) {
    var filters = $("form").serialize();
    var productGroup = $("#valProductGroup").attr('title');
    var productType = $("#valProductType").attr('title');
    var itemsPerPage = $("#ItemsPerPage").val();
    var menuString = $("#Navigation").html();

    // repopulate the paging menu...
    $.ajax({ url: "/Catalog/Ajax/Update/Navigation"
          , type: 'GET'
          , dataType: 'HTML'
          , data: { productGroup: productGroup, productType: productType, itemsPerPage: itemsPerPage, pageIndex: pageIndex, filters: filters }
          , success: function(results) { $("#Navigation").html(results) }
          , failure: function(results) { $("#Navigation").html(oldMenuString) }
});

    // stop event bubbling... (this is not working as expected?)
    return false;
}
