        $('<div class=\"g-mask\"><iframe frameborder=\"0\" scrolling=\"no\"></iframe></div>').appendTo('body');
        this.show().attr('par', this.parent().length ? true : false).appendTo('body').wrapAll('<table class=\"g-popup\"><tr><td></td></tr></table>');
        this.wrapAll('<div class=\"g-popup-wrap\" style=\"width:' + this.outerWidth(true) + 'px\"></div>').before('<div class=\"g-popup-title g-line-dashed\">' + (title ? title : '') + '</div>').before($('<a class=\"g-popup-hide\" href=\"javascript:;\"></a>').click(function() {
            tag.popHide()
        }));
