The example in this article describes how to display the number of elements in a form using JavaScript. Share it with everyone for your reference. The details are as follows:

JavaScript displays the number of elements in the form, excluding the form itself

<!DOCTYPE html>
<html>
<body>
<form id="frm1" action="form_action.asp">
First name: <input type="text" name="fname" value="Donald"><br>
Last name: <input type="text" name="lname" value="Duck"><br>
<input type="submit" value="Submit">
</form>
<p>The number of elements in "frm1" are:
<script>
document.write(document.getElementById("frm1").length);
</script>
</p>
</body>
</html>

I hope this article will be helpful to everyone’s JavaScript programming design.
