javascript - jQuery: Change select background with content change -


i have following select:

<select class="state">     <option value="1">done</option>     <option value="2">closed</option>     <option value="2">open</option>     <option value="2">working on it</option>     <option value="2">waiting</option> </select>

the following script changing color depending of content:

$('.state option:selected').each(function(){     var state = $(this).text();     if(state == 'open') {         $(this).parent().parent().css('background-color', '#e74c3c');     } else if(state == 'working on it') {         $(this).parent().parent().css('background-color', '#f1c40f');     } else if(state == 'closed') {         $(this).parent().parent().css('background-color', '#c0392b');     } else if(state == 'waiting') {         $(this).parent().parent().css('background-color', '#d35400');     } else if(state == 'done') {         $(this).parent().parent().css('background-color', '#27ae60');     } else {         $(this).parent().parent().css('background-color', '#bdc3c7');     } }); $('select').change(     function (){         var color = $('option:selected',this).css('background-color');         $(this).css('background-color',color);     } ).change();

but script not doing: not changing color if change value of select. additionally sure, code shorter.

the select has class because select appear more once on single page.

  1. use addclass , removeclass
  2. use data-* set class add
  3. set style in class
  4. remove class before adding class of selected option

$('.state').change(function() {  $(this).parent().parent().removeclass("default done closed open working waiting");    var state = $("option:selected", this).attr("data-class");    $(this).parent().parent().addclass(state);    }).change();
.done {    background-color: #27ae60;  }    .closed {    background-color: #c0392b;  }    .open {    background-color: #e74c3c;  }    .working {    background-color: #f1c40f;  }    .waiting {    background-color: #d35400;  }    .default {    background-color: #bdc3c7;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>    <div>    <div>      <select class="state">      <option value="1" data-class="done">done</option>      <option value="2" data-class="closed">closed</option>      <option value="2" data-class="open">open</option>      <option value="2" data-class="working">working on it</option>      <option value="2" data-class="waiting">waiting</option>  </select>    </div>  </div>
