如何在jsp中單擊按鈕后永久禁用按鈕

Question

單擊后如何永久禁用按鈕？刷新頁面后它也應保持禁用狀態。但刷新頁面后，該按鈕再次啟用。如何執行此操作？

Answer 1

它真的很簡單，只需將 disabled 屬性更改為 true ..

 <script type="text/javascript">
        function disableButton(btn){
            document.getElementById(btn.id).disabled = true;
            alert("Button has been disabled.");
        }
    </script>

使用 HTML 它看起來像這樣

<!--JavaScript - Disable Button after Click using JavaScript Function.-->
<html>
    <head>
        <title>JavaScript - Disable Button after Click using JavaScript Function.</title>
        <script type="text/javascript">
            function disableButton(btn){
                document.getElementById(btn.id).disabled = true;
                alert("Button has been disabled.");
            }
        </script>
    </head>

    <body style="text-align: center;">
        <h1>JavaScript - Disable Button after Click using JavaScript Function.</h1>
        <p><input type="button" id="btn1" value="Click to disable button." onclick="disableButton(this)"</p>

    </body>

</html>
