Jquery script to take select option and make API call with parameter

jQuery's load function was around in version 1.3. I wonder if that worked well.

If you had selects of id country and city then the following might work:

$('#country').change(function(){
  $('#city').load('search/city.view?value='+$(this).val());
}

Select allOpen in new window

if search/city.view?value=UK returned the following html:

<option value="London">London</option>
<option value="Glasgow">Glasgow</option>
...etc

Select allOpen in new window

What format is the data returned by your city.view script?

This is an example...

<?xml version="1.0" encoding="UTF-8"?>
<list lang="en" datalang="en" countrycode="AU">
  <item value="0">Please select</item>
  <item value="ADL">Adelaide</item>
  <item value="EPZ">Alexandra Headland</item>
  <item value="ASP">Alice Springs</item>
  <item value="EPV">Apollo Bay</item>
  <item value="AYQ">Ayers Rock</item>
  <item value="BNE">Brisbane</item>
  <item value="BME">Broome</item>
  <item value="QYN">Byron Bay</item>
  <item value="CNS">Cairns</item>
  <item value="CUD">Caloundra</item>
  <item value="CBR">Canberra</item>
  <item value="DRW">Darwin</item>
  <item value="EXW">Dunsborough</item>
  <item value="EXZ">Fraser Island</item>
  <item value="OOL">Gold Coast</item>
  <item value="EYJ">Halls Gap</item>
  <item value="HVB">Hervey Bay</item>
  <item value="HBA">Hobart</item>
  <item value="KNX">Kununurra</item>
  <item value="LST">Launceston</item>
  <item value="FFG">Lorne</item>
  <item value="FGP">Magnetic Island</item>
  <item value="MEL">Melbourne</item>
  <item value="MJK">Monkey Mia</item>
  <item value="PER">Perth</item>
  <item value="PTI">Port Douglas</item>
  <item value="RTS">Rottnest Island</item>
  <item value="FKU">Scarborough</item>
  <item value="MCY">Sunshine Coast</item>
  <item value="SYD">Sydney</item>
  <item value="TMW">Tamworth</item>
  <item value="GZC">Whitsundays</item>
</list>

Sorry Chris,

Our answers seem to have crossed over, the main difference between the two is that my code doesn't assume that the city select is empty.

No worries - often happens.

I think it's fair to assume that's the way to do it though :)

Many thanks to both of you for your time and thought.
