The example in this article describes the method of using JavaScript to obtain the values ​​of all elements in the form. Share it with everyone for your reference. The details are as follows:

The following JS code can traverse all elements in the specified form and output the value of the element

<!DOCTYPE html>
<html>
<body>
<form id="frm1" action="form_action.aspx">
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>Return the value of each element in the form:</p>
<script>
var x=document.getElementById("frm1");
for (var i=0;i<x.length;i++)
{
document.write(x.elements[i].value);
document.write("<br>");
}
</script>
</body>
</html>
