How to check if an option is selected?

Question

$('#mySelectBox option').each(function() {
    if ($(this).isChecked())
       alert('this option is selected');
     else
       alert('this is not');
});

Apparently, the isChecked doesn't work. SO my question is what is the proper way to do this? Thanks.

Answer 1

use

 $("#mySelectBox option:selected");

to test if its a particular option myoption:

 if($("#mySelectBox option:selected").text() == myoption){
          //...
 }

Answer 2

In my case I don't know why selected is always true. So the only way I was able to think up is:

var optionSelected = false;
$( '#select_element option' ).each( function( i, el ) {
    var optionHTMLStr = el.outerHTML;

    if ( optionHTMLStr.indexOf( 'selected' ) > 0 ) {
        optionSelected = true;
        return false;
    }
});

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();
