thanks morningz - that's a lot neater than my solution:
$(document).ready(function(){
$("#sweets").change(function (){
var str = "";
$("select option:selected").each(function (){
str += $(this).text() + " ";
});
$("#basket").val(str);
})
$("#crisps").change(function (){
var str = "";
$("select option:selected").each(function (){
str += $(this).text() + " ";
});
$("#basket").val(str);
})
.change();
});
[based on the events/change demo @ jquery.com -
http://docs.jquery.com/Events/change]
