onsubmit 表單提交事件

靜態登錄檔單提交事件

 

如果發現提交不合法,可以通過onsubmit="return false"阻止表單提交

<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script type="text/javascript">
        alert("使用")
        var onsubmitfun = function (){
            alert("靜態登錄檔單提交")
        }
    </script>
</head>
<body>
<form method="get" action="https://localhost:8080">
  <input type="submit" value="靜態提交" onsubmit="onsubmitfun()">
</form>
