It shows the toggle button when screen size become small. 屏幕尺寸变小时，显示切换按钮。 But when I click the button, it refresh the entire page. 但是，当我单击按钮时，它将刷新整个页面。 Not showing the side navbar.I already have bootstrap fixed navbar. 没有显示侧面导航栏。我已经有引导固定的导航栏。 Now I want to add side navbar using w3css file. 现在，我想使用w3css文件添加侧面导航栏。 What I did wrong in my code 我在代码中做错了什么

This is that link from where I takes the code link 这是我获取代码链接的链接

You need to add type="button" or return false to your buttons. 您需要添加type="button"或为按钮return false 。

type="button"

<button type="button" class="w3-button w3-teal w3-xlarge w3-hide-large" onclick="w3_open()">&#9776;</button>

return false

<button class="w3-button w3-teal w3-xlarge w3-hide-large" onclick="w3_open(); return false">&#9776;</button>

If you don't do so, the buttons will be by default type="submit" and force the refresh of the page. 如果您不这样做，则默认情况下，按钮的type="submit"并强制刷新页面。
