Choosing options when choosing through jQuery

If you don’t know what the values ​​are, but you know what the text is inside, you can use the selector :contains()to get the corresponding parameter, get its value, and then set select.

, :contains() , :contains(foo) <p>foo</p>, <p>barfoobar</p> ( ThiefMaster ).

.filter(), .

// relevant option
//     : not entirely sure if .val() will get an option value
var _optionval = $('option:contains("B")').attr('value');

// set select value
$('select').val(_optionval);

, .

:contains() . .

- .filter() .

$('option').filter(function () {

    // we want the option (or optionS) with text that starts with "foo"
    return $(this).text().indexOf('foo') === 0;

    // or maybe just something with an exact match
    //
    // return $(this).text() === 'foo';
});
