当鼠标滚轮在 HTML 中某元素上向上或向下滚动时执行脚本?


onwheel 属性会在鼠标滚轮在元素上向上或向下滚动时触发。你可以尝试运行以下代码来实现onwheel 属性−

示例

<!DOCTYPE html>
<html>
   <body>
      <h3 id = "myid" onwheel = "mouseWheel()">
         This is demo heading.
      </h3>
      <p>Click above and use mouse wheel to change the heading color.</p>
      <script>
         function mouseWheel() {
            document.getElementById("myid").style.color = "red";
         }
      </script>
   </body>
</html>
