I have a e-commerce ticketing app that has multiple ticket types... each with a select drop down for quantity i.e. 0 - 10...  

How do I validate that someone has selected a quantity of 1 or greater for at least 1 of the select drop downs.


Example of the select field is below.
 
 
ADULT
	<select name="ticket[1].qty">
 
									  <option value="0">0</option>	
									  
									  <option value="1">1</option>
									  
									  <option value="2">2</option>
									  
									  <option value="3">3</option>
									  
									  <option value="4">4</option>
									  
									  <option value="5">5</option>
 
									  
									  <option value="6">6</option>
									  
									  <option value="7">7</option>
									  
									  <option value="8">8</option>
									  
									</select>
 
 
 
STUDENT
<select name="ticket[2].qty">
 
									  <option value="0">0</option>	
									  
									  <option value="1">1</option>
									  
									  <option value="2">2</option>
									  
									  <option value="3">3</option>
									  
									  <option value="4">4</option>
									  
									  <option value="5">5</option>
 
									  
									  <option value="6">6</option>
									  
									  <option value="7">7</option>
									  
									  <option value="8">8</option>
									  
									</select>

A simple solution would be to grab the values of the two select boxes and make sure they're not both 0.  The example below assumes that you've got these two select elements inside a form and that you want to validate before the form gets submitted.

jQuery(function(($) {
 $('form').submit(function () {
  var a = $("select[name='ticket\[1\].qty']").val();
  var s = $("select[name='ticket\[2\].qty']").val();
  if (a == 0 && s == 0)
  {
    alert('Please order at least one ticket);
    return false;
  }
  return true;
 });
});

Forgot a closing quote in there.  This should be the script:

jQuery(function(($) {
 $('form').submit(function () {
  var a = $("select[name='ticket\[1\].qty']").val();
  var s = $("select[name='ticket\[2\].qty']").val();
  if (a == 0 && s == 0)
  {
    alert('Please order at least one ticket');
    return false;
  }
  return true;
 });
});
