JavaScript防抖：用于防止重复表单提交等场景

点击一次后，执行防抖函数antiShake，按钮设置为不可用状态，开始计时，计时结束移除不可用状态

|---------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 7 8 9 | hljs html <button onclick="antiShake(this)">防抖测试</button> <script type="application/javascript"> function antiShake(dom) { dom.setAttribute("disabled", "disabled"); setTimeout(() => { dom.removeAttribute("disabled"); }, 3000); } </script> |

顺带聊聊
