How to check if an option is selected?
UPDATE
A more direct jQuery method to the option selected would be:
var selected_option = $('#mySelectBox option:selected');
Answering the question .is(':selected')
is what you are looking for:
$('#mySelectBox option').each(function() { if($(this).is(':selected')) ...
The non jQuery (arguably best practice) way to do it would be:
$('#mySelectBox option').each(function() { if(this.selected) ...
Although, if you are just looking for the selected value try:
$('#mySelectBox').val()
If you are looking for the selected value's text do:
$('#mySelectBox option').filter(':selected').text();

You can get the selected option this way:
$('#mySelectBox option:selected')...
But if you want to iterate all the options, do it with this.selected
instead of this.isChecked
which doesn't exist:
$('#mySelectBox option').each(function() { if (this.selected) alert('this option is selected'); else alert('this is not');});
Update:
You got plenty of answers suggesting you to use this:
$(this).is(':selected')
well, it can be done a lot faster and easier with this.selected
so why should you use it and not the native DOM element method?!

tag info
If you're not familiar or comfortable with is()
, you could just check the value of prop("selected")
.
$('#mySelectBox option').each(function() { if ($(this).prop("selected") == true) { // do something } else { // do something }});
Edit:
As @gdoron pointed out in the comments, the faster and most appropriate way to access the selected property of an option is via the DOM selector. Here is the fiddle update displaying this action.
if (this.selected == true) {
appears to work just as well! Thanks gdoron.
