The following behaves differently between jQuery 1.9 and 1.10+:
<select id="s1">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
$('#s1 option[value=1]').hide();
$('#s1').val('');
The idea behind this code is to select the first non-hidden option, after hiding some options, including the currently selected one.
Since jQuery 1.10+ the $('#s1').val('');
no longer selects the first non-hidden option, while .val(<some proper value for the particular select box>)
works ok.
Trying the following approaches does not help because both selectedIndex
and .first().val()
consider the hidden options:
$("#s1").prop("selectedIndex", 0);
$('#s1 option').first().prop('selected', true);
Next thing that comes to mind (also suggested by C-link) also does not work, because the :visible
selector does not work properly for select options.
$('#s1 option:visible').first().prop('selected', true);
Looking for some generic way (not depending on knowledge of what are the particular values and what options have been hidden) to achieve the same behaviour as $('#s1').val('');
in old jQuery.

You can easily do this using class
$('#s1 option[value=1]').hide();
$('#s1 option[value=1]').addClass('hidden');
$('#s1 option[value=1]').removeClass('visible')
$('#s1').val('');
$('#s1 .visible:first').val();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="s1">
<option class="visible" value="1">1</option>
<option class="visible" value="2">2</option>
<option class="visible" value="3">3</option>
</select>

Compiled from everybody else's answers/comments the following:
$('#s1 option').each(function () {
if ($(this).css('display') != 'none') {
$(this).prop("selected", true);
return false;
}
});

Try this code
$('#s1 option[value="1"]').hide();
$('#s1').find('option').each(function()
{
if($(this).is(':visible'))
{
$(this).attr("selected","selected");
return false;
}
});

Try this:
<select id="s1">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
$('#s1 option[value=1]').hide();
var firstVisibleValue = '';
$('#s1').children().each(function(){ //iterate options
//check if option is visible - if not set to display none, which is what `.hide` does.
if($(this).css('display') != 'none'){
firstVisibleValue = $(this).val();
return false; //stop iterating
}
});
$('#s1').val(firstVisibleValue);
