fills the selection of another selection value using jquery


hi all I have seen many question but no one has fulfilled my thirst. I want to populate select on the basis of one other select. I am using zend framework. I have a select that will select a account and on the basis of that selected id i want to populate other select with values fetched from database based on first selected option. I have first select which is like this

<select name='select1'>
<option value='1'>accoutn1</option>
<option value='2'>accoutn2</option>
<option value='3'>accoutn3</option>
<option value='4'>accoutn4</option>

Now what I want that on the basis of first select, the other other select is populated using jquery. The options will be values fetched from database on the basis of first selected value. my other select is

<select name='client'>

Which function of jquery supports this that I can fetched values from database on the basisi of selected option and populate other select. I am using zendframe work. Any idea?
