comboboxes how to?

abcde · 12-14-2010, 12:54 AM

hi everyone,

I want to make 2 comboboxes: country and city, but I want the values on city change base on that country user select.

ex: if we select USA then we will see New York but not Tokyo, but if we select Japan then we only see Tokyo, not NY.

How do i do that?

Code:

<select  name="country">
  <option disabled selected>Select</option>
  <option value="us">USA</option>
  <option value="japan">Japan</option>
</select>

<select  name="city">
  <option disabled selected>Select</option>
  <option value="1">New York</option>
  <option value="1">Tokyo</option>
</select>

That can't be done with HTML alone, so you'll need to use JavaScript. On the first combo box, you can add an onchange event that looks at the selection and populates the second combo box accordingly.

Or use Ajax, here is an example:
