Enhancing the structure and authentication of license plates

I'm having trouble figuring out how to apply Javascript to the text area. Can you advise on whether it's best to use onfocus, onblur, or onclick?

Here is the code for the text area:

<input type="text" name="c_Kenteken" id="invoerKenteken" class="zoek_kentekenplaat" />

And here is the script:

<script language="javascript" type="text/javascript">
... (Script content has been omitted for brevity)
</script>

The CSS for the text area:

... (CSS content has been omitted for brevity)

You can view the JSFIDDLE here.

If anyone can help me with this issue, I would greatly appreciate it!

Thank you,

Jazper

It is quite common to want real-time formatting as users type, but this can raise performance concerns. One way to achieve this is by using the keydown or keyup event like so:

<input type="text" onkeyup="myFunction()">

Keep in mind that this event will be triggered every time a user types or removes their finger from a key, potentially causing performance issues if used excessively. However, for small amounts of text like yours, it should not be a major problem, as the event would only fire around 10 times or so.

If you wish to optimize your code further, consider exploring . This link provides an example of how to throttle your events to prevent them from executing each time they occur.
