javascript - 切换菜单后丢失导航栏 css

标签 javascript jquery html css

我的响应式导航栏有问题。当我在屏幕较小时单击切换按钮时，它会响应并打开隐藏的导航菜单，但菜单没有附加导航栏的原始 css。任何帮助，将不胜感激。

      </html>

JS:

function myFunction() {
  var x = document.getElementById("myTopnav");
  if (x.className === "topnav") {
    x.className += "responsive";
  } else {
    x.className = "topnav";
  }
}

最佳答案

您在 CSS 中引用了 .topnav.responsive，但在 JS 中将字符串“responsive”添加到“topnav”的类名中，这导致 .topnavresponsive。您可以切换 .responsive 而不是使用 .classList.toggle()

function myFunction() {
  var x = document.getElementById("myTopnav");
  if (x.className === "topnav") {
    x.classList.toggle("responsive");
  }
}
