如何设置应在HTML中禁用指定的元素/元素组？
使用Disabled属性禁用元素。该属性可用于以下元素：<button>，<input>，<select>，<textarea>等。
示例
您可以尝试运行以下代码以实现禁用的属性-
<!DOCTYPE html>
<html>
<body>
<p>Which sports do you like?</p>
<form action = "" method = "get">
<input type = "checkbox" name = "vehicle" value = "football" checked> Football<br>
<input type = "checkbox" name = "vehicle" value = "cricket" checked> Cricket<br>
<input type = "checkbox" name = "vehicle" value = "hockey"> Hockey<br>
<input type = "submit" value = "Submit" disabled>
</form>
</body>
</html>
