以下是您要求的翻译内容：
其实非常简单，只需将 disabled 属性更改为 true。
<script type="text/javascript">
function disableButton(btn){
document.getElementById(btn.id).disabled = true;
alert("按钮已被禁用。");
}
</script>
使用 HTML，它看起来会是这样的：
<!--JavaScript - 在点击后使用 JavaScript 函数禁用按钮。-->
<html>
<head>
<title>JavaScript - 在点击后使用 JavaScript 函数禁用按钮。</title>
<script type="text/javascript">
function disableButton(btn){
document.getElementById(btn.id).disabled = true;
alert("按钮已被禁用。");
}
</script>
</head>
<body style="text-align: center;">
<h1>JavaScript - 在点击后使用 JavaScript 函数禁用按钮。</h1>
<p><input type="button" id="btn1" value="点击以禁用按钮。" onclick="disableButton(this)"></p>
</body>
</html>
英文:
its really easy , just change disabled property to true..
<script type="text/javascript">
function disableButton(btn){
document.getElementById(btn.id).disabled = true;
alert("Button has been disabled.");
}
</script>
with HTML it would look smth like this
<!--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>
