javascript - jQuery: styling and unstyling on click radio button using parent(), next() -


i have 3 identical sections. exact same each other.
what i'm trying achieve when click on ".rad1"(first radio button), styles label.
when click on ".rad2", should unstylize first radio button , stylize second radio button.

want happen in own section, aka, when click on 1 section, styles applied section, no other section.

this have, haven't found way achieve it:

$('.rad1').click(function() {      $(this).parent('.label1').css('background', 'red');  });  $('.rad2').click(function() {      $(this).parent().next('.label1').css('background', 'transparent');      $(this).parent('.label2').css('background', 'red');  });
.form-section {  background: orange;  border: 1px solid black;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div class="form-section">      <form action="">          <div class="first">              <label for="radio" class="label1">                  <input type="radio" class="rad1" name="rad">first              </label>          </div>          <div class="second">              <label for="radio" class="label2">                  <input type="radio" class="rad2" name="rad">second              </label>          </div>      </form>  </div>  <!------------section-->  <div class="form-section">      <form action="">          <div class="first">              <label for="radio" class="label1">                  <input type="radio" class="rad1" name="rad">first              </label>          </div>          <div class="second">              <label for="radio" class="label2">                  <input type="radio" class="rad2" name="rad">second              </label>          </div>      </form>  </div>  <!------------section-->  <div class="form-section">      <form action="">          <div class="first">              <label for="radio" class="label1">                  <input type="radio" class="rad1" name="rad">first              </label>          </div>          <div class="second">              <label for="radio" class="label2">                  <input type="radio" class="rad2" name="rad">second              </label>          </div>      </form>  </div>

i'd this:

$('input[name="rad"]').click(function() {   $(this).closest('form').find('label').css('background', 'transparent')   $(this).parent().css('background', 'red'); }); 

$('input[name="rad"]').click(function() {    $(this).closest('form').find('label').css('background', 'transparent')    $(this).parent().css('background', 'red');  });
.form-section {    background: orange;    border: 1px solid black;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div class="form-section">    <form action="">      <div class="first">        <label for="radio" class="label1">          <input type="radio" class="rad1" name="rad">first        </label>      </div>      <div class="second">        <label for="radio" class="label2">          <input type="radio" class="rad2" name="rad">second        </label>      </div>      </form>  </div>  <!------------section-->  <div class="form-section">    <form action="">      <div class="first">        <label for="radio" class="label1">          <input type="radio" class="rad1" name="rad">first        </label>      </div>      <div class="second">        <label for="radio" class="label2">          <input type="radio" class="rad2" name="rad">second        </label>      </div>      </form>  </div>  <!------------section-->  <div class="form-section">    <form action="">      <div class="first">        <label for="radio" class="label1">          <input type="radio" class="rad1" name="rad">first        </label>      </div>      <div class="second">        <label for="radio" class="label2">          <input type="radio" class="rad2" name="rad">second        </label>      </div>      </form>  </div>

it's better add , remove class instead of styling lables using .css().

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
