在我的jquery对话框的按钮上添加一个类

I have a jQuery dialog:

我有一个jQuery对话框：

    // Configure buttons
    var dialogButtons = {};

    dialogButtons[buttonConfirm] = function () {
        $.ajax({
            type: "Post",
            url: href,
            cache: false,
            success: function (data) { var func = success; window[func](data); }
        });
        $(this).dialog("close");
    };

    dialogButtons[buttonCancel] = function () {
        $(this).dialog("close");
    };

    // Configure dialog
    $dialog.dialog(
        {
            modal: true,
            closeOnEscape: true,
            resizable: false,
            buttons: dialogButtons
        });

    // Opening dialog
    $dialog.dialog('open');
