我的新网站上有一个侧边栏，可以切换打开和关闭的部分，并且可以执行此操作。
但是在任何浏览器中，只有当JS脚本存在时，我才能再实际点击内部链接。
此外，控制台中没有错误。
请你能帮助我，我没有想法：）
这是JS，
(function($) {
"use strict";
$.fn.tree = function() {
return this.each(function() {
var btn = $(this).children("a").first();
var menu = $(this).children("ul").first();
var isActive = $(this).hasClass('active');
//initialize already active menus
if (isActive) {
menu.show();
btn.children(".fa-angle-left").first().removeClass("fa-angle-left").addClass("fa-angle-down");
}
//Slide open or close the menu on link click
btn.click(function(e) {
e.preventDefault();
if (isActive) {
//Slide up to close menu
menu.slideUp();
isActive = false;
btn.children(".fa-angle-down").first().removeClass("fa-angle-down").addClass("fa-angle-left");
btn.parent("li").removeClass("active");
} else {
//Slide down to open menu
menu.slideDown();
isActive = true;
btn.children(".fa-angle-left").first().removeClass("fa-angle-left").addClass("fa-angle-down");
btn.parent("li").addClass("active");
}
});
/* Add margins to submenu elements to give it a tree look */
menu.find("li > a").each(function() {
var pad = parseInt($(this).css("margin-left")) + 10;
$(this).css({"margin-left": pad + "px"});
});
});
};
}(jQuery));
$('<i class="fa fa-angle-left pull-right"></i>').appendTo('.nav-left > li > a');
/* Sidebar tree view */
$(".sidebar .nav-left li").tree();
这是HTML：
<!-- Left side column. contains the logo and sidebar -->
<aside class="left-side sidebar-offcanvas">
<!-- sidebar: style can be found in sidebar.less -->
<section class="sidebar">
<!-- Sidebar user panel -->
<div class="user-panel">
<div class="pull-left image">
<img src="/img/avatar3.png" class="img-circle" alt="User Image" />
</div>
<div class="pull-left info">
<p>Hello, <span class="insert_usrdata_name"></span></p>
<a href="#"><i class="fa fa-circle text-success"></i> Online</a>
</div>
</div>
<!-- search form -->
<form action="#" method="get" class="sidebar-form">

谢谢你的时间，我会发布一个真实的链接，但似乎没有在这里赞扬...
答案 0 :(得分：1)
在您的循环中，您在每个链接的e.preventDefault()事件中设置click，阻止点击执行任何操作：
var btn = $(this).children("a").first();
...
btn.click(function(e) {
e.preventDefault();
...
}
您在a列表中的每个.nav-left元素上调用此内容。我真的不知道你想要的结果是什么，但是如果你删除了链接现在将正常运行，但页面会改变，你的click功能对新页面没有任何影响。< / p>
修改：来自评论：
您是否可以对其进行调整，以便在点击内部没有
<a>的父<ul>时，该链接有效，而当父<a>时确实有<ul>，e.preventDefault();在父<a>上强制执行？
是的，只需在click函数周围添加一项检查，看看a元素旁边是否有ul元素：
if (btn.next('ul').length) {
btn.click(function(e) {
...
}
}
