Jquery nextUntil and prevUntil including issue

Question

I am trying to include first and last selectors along with nextUntil and prevUntil

JQUERY

$('.selectedDay').parent().prevUntil('li.weeks').css('background', '#F00');

$('.selectedDay').parent().nextUntil('li.weeksClose').css('background', '#F00');

JSFIDDLE

Answer 1

Try this:

$('.selectedDay').parent().prevAll('.weeks').first().css('background', '#F00');

$('.selectedDay').parent().nextAll('li.weeksClose').first().css('background', '#F00');

Answer 2

Solution using jquery (javascript library)

Since

• li.weeks is preceded by li.weeksClose; and
• li.weeksClose is followed by li.weeks

why not simply use:

$('.selectedDay').parent().prevUntil('li.weeksClose').css('background', '#F00');
$('.selectedDay').parent().nextUntil('li.weeks').css('background', '#F00');

Solution using axe (CSS Library)

Alternatively, instead of using a javascript library like jQuery, you can use a CSS Library like axe.

You will need to use the following two axe selectors:

• < selects immediate parent (it's the opposite of > in standard CSS)
• ! selects any previous sibling (it's the opposite of ~ in standard CSS)

Then you can write the following style rules:

.selectedDay < li ! li,
.selectedDay < li ~ li {
background-color: rgb(255, 0, 0);
}

.selectedDay < li ! li.weeks ! li,
.selectedDay < li ~ li.weeksClose ~ li {
background-color: rgb(255, 255, 255);
}

Working Example:

.selectedDay < li ! li,
.selectedDay < li ~ li {
background-color: rgb(255, 0, 0);
}

.selectedDay < li ! li.weeks ! li,
.selectedDay < li ~ li.weeksClose ~ li {
background-color: rgb(255, 255, 255);
}

Answer 3

Done.

$('.selectedDay').parent().prevAll('.weeks').first().css('background', '#F00');
    $('.selectedDay').parent().prevUntil('.weeks').css('background', '#F00');

    $('.selectedDay').parent().nextAll('li.weeksClose').first().css('background', '#F00');

    $('.selectedDay').parent().nextUntil('li.weeksClose').css('background', '#F00');
