仅在移动视图中单击汉堡时，粘性导航栏消失

Question

不知道为什么，但粘性导航栏工作正常，除非我在移动视图中向下滚动。当我单击“菜单单击此处”时，整个导航栏就会消失。

我认为 javascript 函数正在删除粘性类，但我不知道如何解决这个问题。

/* Toggle between adding and removing the "responsive" class to bottomnav when the user clicks on the icon */

function myFunction() {

var x = document.getElementById("mybottomnav");

if (x.className === "bottomnav") {

x.className += " responsive";

} else {

x.className = "bottomnav";

}

}

问题出在你的myFunction功能上。<a href="javascript:void(0);" class="icon" onclick="myFunction()"><p>Menu Click Here </p>&nbsp; ☰</a>在这里，您调用 yourmyFunction()来切换汉堡菜单的状态。但是，myFunction无法管理切换。因此，要使其正常工作，请更改您当前的版本function myFunction() {&nbsp; var x = document.getElementById("mybottomnav");&nbsp; if (x.className === "bottomnav") {&nbsp; &nbsp; x.className += " responsive";&nbsp; } else {&nbsp; &nbsp; x.className = "bottomnav";&nbsp; }}到下面这个：function myFunction() {&nbsp; var x = document.getElementById("mybottomnav");&nbsp; if(x.classList.contains("responsive")) {&nbsp; &nbsp; x.classList.remove("responsive");&nbsp; } else {&nbsp; &nbsp; x.classList.add("responsive");&nbsp; }}
