我有jquery选项卡，当我点击小x关闭它时，调用我的委托并删除标签部分，但标签内容不是。在开发工具中，我仍然在dom中看到它。我似乎也没有收到任何错误。只是想知道是否有人知道为什么？请注意，我在标签内容中使用了ace编辑器，但我认为这不重要。
在我删除dom之前看起来像：
<div id="tabs" style="padding: 0; margin: 0; height: 100%" class="ui-tabs ui-widget ui-widget-content ui-corner-all">

App.lua.editor div中显然有很多东西，但是这些都是由ace编辑器库提供的。
这是我用来删除标签及其内容
的内容var tabs = $("#tabs").tabs();
tabs.delegate( "span.ui-icon-close", "click", function() {
if(confirm("Are you sure you want to close?") == false){
return;
}
var panelId = $( this ).closest( "li" ).remove().attr( "aria-controls" );
alert(panelId);
$("#" + panelId).remove();
tabs.tabs("refresh");
});
如前所述，标签li确实已被删除，但App.lua.content div仍保留在DOM中，即使panelID为＆＃34; App.lua.content＆＃34;在警报中。我假设什么都不能阻止从DOM中删除元素？
答案 0 :(得分：2)
这是因为ID包含.，因此选择器会选择ID为App但具有lua和content类的元素。尝试逃避点：
$("#" + panelId.replace(/\./g, '\\.')).remove();
