我有一个手风琴，当打开一个面板时，它会从服务器获取 html，并将其呈现为手风琴作为前一个手风琴的子级。当我单击子手风琴时，它会触发父 onactivate 事件

@model IEnumerable<String>

@{
    Layout = null;
}

这是因为事件冒泡，意味着由子元素触发的事件将一直冒泡到文档对象。

在您的情况下，您需要测试触发事件的元素是使用 eventstarget属性还是使用ui的新标头。

然后

    $("#Nxts").on("accordionactivate", function (event, ui) {
        if ($(ui.newHeader).parent().is('#Nxts') && ui.newPanel.length > 0) {
            if (ui.newPanel.html() == "") {
                var date = $('#SelectedDate').val();
                var active = $("#Nxts").accordion("option", "active");
                var text = $.trim($("#Nxts h3").eq(active).text());
                PopulatePanel(ui.newPanel, text, date);
            }
        }
    });

防止从子手风琴传播事件

$("#Nxts").on("accordionactivate", '.accordion', function(e){
    e.stopPropagation():
});
