jquery - JQuery Accordion beforeActivate 不起作用

问题描述

似乎从来没有碰到过这个代码。我尝试了 ID 选择器，但仍然没有触发。

我在 JqueryUI 版本 1.12.1 上。

 $(".accordConditionSet").accordion({
        beforeActivate: function( event, ui ) {
            alert(ui.newPanel.text()); 
        }
        });

标签： jqueryaccordion

解决方案

我有使用基于 Id 的相同概念beforeActivate in accordion Jquery UI

$( "#accordion" ).accordion({beforeActivate: function( event, ui ) {alert(ui.newPanel.text())}});
