actually it might work
var obj = $("#mdiv select");
for(var i=0; i < obj.length; i++) {
obj.eq(i) ....
}
// the above method will get alll <select> tags within a <div> tag and loop
then
if you want to loop the options within them you can either make obj to be
$("#mydiv select option");
or you can run a loop within a loop like so
var obj = $("#mdiv select");
for(var i=0; i < obj.length; i++) {
var objtwo = obj.eq(i);
var ops= ("option", objtwo);
for(var j = 0; j < ops.length; i++) {
if(ops.eq(i) == 0) {
break;
} else {
// do stuff
}
}
}
this should be according to your new idea. but will this really work for you
? too much looping does use more memory.
the simple click function i mentioned would use less memory since i set
$("select") it would get the click of any select you do click. and it
returns the value of the selected item.
if you have a specific goal you want to achieve it would allow us to help
you better if we knew.
<script>
$(function() {
$("select").click(function() {
var value = $(this).val();
if(val != 0) {
// do what you need to do
} else {
alert("you have not selected an option");
}
});
});
</script>
