当在HTML元素上按下鼠标按钮时执行脚本?
在 HTML 中使用 onmousedown 属性在元素上按下鼠标按钮时执行脚本。
示例
您可以尝试运行以下代码来实现onmousedown属性 -
<!DOCTYPE html><html> <body> <h3 id = "myid" onmousedown = "mouseDown()" onmouseup = "mouseUp()"> This is demo heading. </h3> <p>Click above and then release.</p> <script> function mouseDown() { document.getElementById("myid").style.color = "yellow"; } function mouseUp() { document.getElementById("myid").style.color = "blue"; } </script> </body></html>
