我有一个带有按钮和 onclick 功能脚本的 html 脚本，可以将我带到 google.com，但它似乎不起作用。坚持了几个小时。我也是 HTML 新手。
什么都试过了。第336行和353行应该是需要的内容。第 136 行应该是按钮本身。我不明白怎么了。有人遇到过这个问题吗？

<p>Had to do this effect in a recent project and wanted to share it with you :). To change the background, edit the data-image on the canvas tag. You can also change the magnet effect intensity by changing the magnet variable</p>

最佳答案
如果您尝试制作一个将您带到 google.com 的按钮，我建议您使用 a 标签，而不是按钮标签。单击该标签会自动将您链接到所需的目的地。
例子:
<a href="https://www.example.com/"> Example </a>如果您希望链接看起来像一个按钮，那么只需查看 css 选项即可。我建议你看这里:https://www.w3schools.com/css/css_link.asp
a {
background-image:linear-gradient(to bottom, lightblue, aquamarine);
padding:5px;
text-decoration:none;
color:black;
padding-right:50px;
padding-left:50px;
margin-top: 50px;
margin-left: 50px;
display: inline-block;
font-size:25px;
border-radius:5px;
box-shadow: 1px 1px green;
}<a href="https://www.example.com"> Example </a>如果您决心使用 <button>标签，那么您需要做的就是在该按钮标签内添加一个 onclick 属性。因此，您可以将代码更改为 <button id="btncmd" onclick="cmd()">Videos</button> .
你想要的例子:
function cmd() {
window.location.href = "https://www.example.com/"; // I'm using example but you can use google.
}<button id="btncmd" onclick="cmd()">Videos</button>关于javascript - 尝试制作一个按钮，将您带到谷歌页面，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57029160/
