The example in this article describes how to use JavaScript to control whether buttons are available or unavailable. Share it with everyone for your reference. The details are as follows:
The following JS code controls whether the button is available through the disabled attribute of the button object
<!DOCTYPE html>
<html>
<body>
<form>
Buttons:
<input type="button" id="firstbtn" value="OK">
<input type="button" id="secondbtn" value="OK">
</form>
<p>Click the button below to disable the first button above.
</p>
<button onclick="disableElement()">Disable button</button>
<script>
function disableElement()
{
document.getElementById("firstbtn").disabled=true;
}
</script>
</body>
</html>I hope this article will be helpful to everyone’s JavaScript programming design.
