javascript - 单击菜单项时移动菜单不会折叠

问题描述

我遇到了一个模板问题，当单击菜单项时移动菜单不会折叠。试图解决它添加额外的类，额外的 ID，但仍然存在。它仅在再次单击汉堡包图标时关闭/隐藏。而且这特别烦人...

导航栏 html 代码是：

<!-- Fixed navbar -->
    <div class="navbar navbar-smak navbar-fixed-top" id="navbar" role="navigation">
        <div class="container">
            <div class="navbar-header">
                <a class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse"><i class="fa fa-bars"></i></a>
                <h1><a class="navbar-brand animate" href="#home">TEST SITE</a></h1>
            </div>
            <div class="navbar-collapse collapse">
                <ul class="nav navbar-nav navbar-right animate">
                    <li><a class="btn-navbar" href="#home">Home</a></li>
                    <li><a href="#blog">Blog</a></li>
                    <li><a href="#contact">Contacto</a></li>
                </ul>
            </div>
            <!--/.nav-collapse -->
        </div>
    </div>

这是我正在处理的虚拟 html 文件，请随时下载并检查：https ://aleare.com.ar/testing3/index2tst.html

这是处理折叠菜单的函数： 

$('a[href*=#]').each(function () {
    if (filterPath(location.pathname) == filterPath(this.pathname) && location.hostname == this.hostname && this.hash.replace(/#/, '')) {
        var $targetId = $(this.hash),
            $targetAnchor = $('[name=' + this.hash.slice(1) + ']');
        var $target = $targetId.length ? $targetId : $targetAnchor.length ? $targetAnchor : false;

        if ($target) {

            $(this).click(function () {

                //Hack collapse top navigation after clicking
                topMenu.parent().attr('style', 'height:0px').removeClass('in'); //Close navigation
                $('.navbar .btn-navbar').addClass('collapsed');

                var targetOffset = $target.offset().top - 52;
                $('html, body').animate({
                    scrollTop: targetOffset
                }, 800);
                return false;
            });
        }
    }
});

有人知道它为什么失败吗？

解决方案

你必须有更多的标记，例如topMenu 和filterPath。

但是，如果我正确理解您的问题，听起来您希望在您从移动菜单中选择一个项目时关闭移动菜单。我没有使用您的代码，而是从 Bootstrap 示例中借用了一个导航栏，并添加了一些额外的代码，以便在您单击菜单中的链接时关闭菜单。如果引导程序中内置了类似的东西，我不会感到惊讶，我假设你正在使用它？如果没有，您可以通过在“适当”时触发对汉堡包的点击来做类似的事情：

$('.nav-link:not(.dropdown-toggle), .dropdown-item').each(function () {

		$(this).on("click", function(e) {
    	$(".navbar-toggler").trigger("click");
      alert($(this).attr("href"));
    	
    });
});
