Adding additional string to an existing value in a HTML form's input box before submission
I have a form with an input box and I want to change the value before submit.
Example:
<form action="savefiends.php" method="post">
<input type="text" name="id" value="123456"><br>
<input type="submit">
</form>
How can I save the value as 123456@example.com without editing savefiends.php?
P.S. user can edit the value
html forms post input save

You can use the onsubmit attribute as shown in the snippet below.
Note: I added extra checking to avoid appending "@example.com" if already present. Also I replaced the action attribute content by "#" to avoid form submission.
function resetId(){
var idInput = document.getElementById("id");
var suffix="@example.com";
// just to check if @example.com is already present
var checkRegExp=new RegExp(suffix + "$");
if (!idInput.value.match(checkRegExp)) idInput.value +="@example.com";
alert("Value before submit:" + idInput.value);
}<form action="#" method="post" onsubmit="resetId();return false">
<input type="text" name="id" value="123456" id="id"><br>
<input type="submit">
