Question

我的菜单效果很好，但是当我点击＆＃34;包裹＆＃34;的下拉菜单时在导航中，在我可以选择选项之前关闭下拉列表。这只发生在移动设备上。

有谁能告诉我这里有什么事吗？

Answer 1

在a文件中，您定位导航栏内的所有navbar-toggle标记（包括// Closes the Responsive Menu on Menu Item Click $('.navbar-collapse ul li a').click(function() { $('.navbar-toggle:visible').click(); });），以便在点击任何链接时折叠移动菜单。

目前你有这个：

// Closes the Responsive Menu on Menu Item Click
$('.navbar-collapse ul li a:not(.dropdown-toggle)').click(function() {
    $('.navbar-toggle:visible').click();
});

您可以使用jQuery :not() Selector

来阻止这种情况

// Highlight the top nav as scrolling occurs
$('body').scrollspy({
  target: '.navbar-fixed-top'
})

// Closes the Responsive Menu on Menu Item Click
$('.navbar-collapse ul li a:not(.dropdown-toggle)').click(function() {
  $('.navbar-toggle:visible').click();
});

**作为旁注，如果您尚未准备就绪，则应考虑通过验证流程运行您的网站：请参阅validator.nu作为示例。

工作示例：

body {
  position: relative;
}
section {
  padding: 50px;
  height: 500px;
}
section:nth-child(3) {
  background-color: lightgreen;
}
section:nth-child(4) {
  background-color: lightblue;
}
section:nth-child(5) {
  background-color: darkblue;
}
section:nth-child(6) {
  background-color: lightcoral;
}
section:nth-child(7) {
  background-color: darkmagenta;
}
section:nth-child(8) {
  background-color: lightskyblue;
}
section:nth-child(9) {
  background-color: lightgoldenrodyellow;
}

我在下面的href="#"行中看到您的网站缺失只是添加它将解决您的问题

<a class="dropdown-toggle" data-toggle="dropdown" role="button">Packages<span class="caret"></span></a>
