i want to change the Style of all Classes by an mouseover / mouseout event.
var shadow = document.getElementsByClassName('shadow-primary');
for (var k = 0; k < shadow.length; k++) {
  var hi = shadow[k]
  hi.onmouseover = function() {
    hi.style["box-shadow"] = "10px 10px 10px #1D618C, 5px 5px 5px #1D618C";
    //console.log(hi);
  }
  hi.onmouseout = function() {
    hi.style["box-shadow"] = "none";
    //console.log(hi);
  }
}<div class="panel panel-primary shadow-primary">
  <div class="panel-heading">
    <h3 class="panel-title">TESTING</h3>
  </div>
  <div class="panel-body">
    <strong>TEST0</strong>
  </div>
</div>
<br><br><br><br>
<div class="panel panel-primary shadow-primary">
  <div class="panel-heading">
    <h3 class="panel-title">TESTING</h3>
  </div>
  <div class="panel-body">
    <strong>TEST1</strong>
  </div>
</div>My Problem is as you can see in the Code Snippet. Cause of my bad coded for loop just the last array is doing what i want.
Could you tell me how it is possible to doing the code Work with all Elements with the Class "shadow-primary".
Please no answers how to do that with an HTML Event Handler. TY :)
