In general:
We made a script which did this, however a bit limited because of the
client/server-problems mentioned.
The script is part of a registration-form, and pick out a city based on the
zip entered. We didn't want the list of zipcodes and cities in JS since it
would be quite huge.
Don't remember the excacts but in general: (simplified model)
<form name=oFrm>
<input name=zip onBlur='fetch();'><input name=city>
</form>
Fetch() is a function that opens a new pop-up window at 50x50px, and set the
url-property of this window using JS (ex:)
var strURL = "find_city.php?zip=" + document.oFrm.zip.value;
The find_city.php script recieves the zip in a get-var, and can connect to
mysql and retrieve the city etc. and closes itself.
find_city then outputs JS (ex):
<script>
opener.document.oFrm.city.value = "$the_right_city";
self.close();
</script>
The "drawbacks" here is a window flashing a short second or so...
You can make this thing run queries or whatever...
Wrote the above from memory, so the syntax might be a bit of, but the flow
is the same.
have a nice day!
