Question

Basically I have two forms
The first form Is a simple select box which submits it’s value to be processed and inserted into a database (mysql)
However on the same page I have a second form with a select box which will be auto populated with the results from the database(ajax / php), depending on which option was chosen from the first forms select box

So anyway I need some way to store the first select box’s chosen value in a variable without submitting the form

Answer 1

You can try.

$('#firstForm').submit(function(){
var firstValue = $('#firstForm select').val()
 //do your ajax call.

return false //then return false or 
            //preventDefault should keep the form from submitting
})
