如何使用颜色选择器将CSS颜色应用于父元素？

Question

I have a color picker which appears by clicking on pencil glyphicon. I just want to apply color from color picker on list elements ie which is grand parent of pencil glyphicon. I have a following ruby front end code:

 <% categories.each(function (category) { %>
    <li id="<%= category.id %>" class="Round-boxes my-sortable">

      <% if(category.get("is_owner")) { %>   
        <div class="color-picker-pencil picker">
           <span class="glyphicon glyphicon-pencil"></span>
        </div>
      <% } %> 
    </li>
  <% }); %>

I am following this tutorail according to which I have a following JS code with a slighter change.

JS code:

  applyColor: function(event) { myel = $(event.target).parent().parent() console.log(myel); $('.picker').colpick({ layout: 'hex', submit: 0, colorScheme: 'dark', onChange: function(hsb, hex, rgb, myel, bySetColor) { $(myel).css('background-color:', '#' + hex); } }).keyup(function() { $(this).colpickSetColor(this.value); }); } 

What Should i do to achieve this ? Thanks in advance.

Answer 1

It was just a syntax error in applyColor function and a little code change, I replaced following code in place of existing:

    applyColor: function(event){
    $('.picker').colpick({
      layout:'hex',
      submit:0,
      colorScheme:'dark',
      onChange:function(hsb,hex,rgb,myel,bySetColor) {

        myel = $(myel).parent();
        $(myel).css('background-color','#'+hex);

      }

    }).keyup(function(){

    $(this).colpickSetColor(this.value);

    });

  }

And every thing works fine. See the line two lines of code inside onChange body. And compare it with code in question.

Answer 2

Did you try to use the parent() Jquery function?

onChange: function(hsb, hex, rgb, myel, bySetColor) {

       $(myel).parent('li').css('background-color:', '#' + hex);
     }
