Add script to autofill streetname and city to cb registration form

Hello,

I have nice looking  cb registration form with fields postalcode, housenumber, streetname and cityname.
Now I have a js (ajax) script to autofill streetname and cityname by filled in postalcode and housenumber.
How can I add the script to the form? Is there a html or php file I can modify?

Thanks, Theo

Easiest way is to use CB Auto Actions. You can then inject your script into the registration form using registration form display triggers.

We do not provide core file modification support in any way and your changes will be lost when you update CB.

Thanks for answering.
What I also need is code added to the field like:
Postcode <input type=text id=postcode onkeyup='check_pc("postcode",this.value)' autofocus>
How can I do that?

Thanks, Theo

As a field? Use Custom HTML field. Note your JS might be filtered out by Joomla's WYSIWYG though.

I already tried that. But we have field title and field name and a editor to put html code.
But how do I combine the code with de field name?
Normally in html de fieldname is within the code like:
<tr><td>Postcode</td> <td><input type=text id=postcode onkeyup='check_pc("postcode",this.value)' autofocus></td></tr>

You just set the field name in the Custom HTML fields title parameter or set it to display on 2 lines without a title then format the HTML however you want.
