如何创建循环导航菜单

标签： javascript html css

我从Codepen示例中复制了代码，但是我的样式没有受到影响！

Codepen link ：

我找不到问题所在！ 我的代码：

(function() {

  var button = document.getElementById('cn-button'),
    wrapper = document.getElementById('cn-wrapper');

  //open and close menu when the button is clicked
  var open = false;
  button.addEventListener('click', handler, false);

  function handler() {
    if (!open) {
      this.innerHTML = "Close";
      classie.add(wrapper, 'opened-nav');
    } else {
      this.innerHTML = "Menu";
      classie.remove(wrapper, 'opened-nav');
    }
    open = !open;
  }

  function closeWrapper() {
    classie.remove(wrapper, 'opened-nav');
  }

})();

别忘了连接外部库和框架。

  //open and close menu when the button is clicked
  var open = false;

  function handler() {
    if (!open) {
      this.innerHTML = "Close";

      classie.remove(wrapper, 'opened-nav');

    open = !open;

答案 1 :(得分：1)

从此类网站复制代码时，应检查是否有自动添加的库。对于Codepen，您可以在每个标签的开头按齿轮符号进行操作。

对于您的特定情况，请参见“ HTML”选项卡的笔设置。在“标头填充”部分中有一个库链接。

我将其复制到Jsfiddle，并且工作正常。

我刚刚添加了这些行
