Manual hover function in javascript -


i not know wrong, hover function wrote here stays when not hovering button. know there simpler way hover object, learning basics, helpful wrong exact code have. 

<head>   <style>     .tabstrip {       background-color: #e4e2d5;       padding: 15px;       height: 22px;       width: 130px;       margin: auto;     }      .tabstrip div {       float: left;       font: 14px arial;       cursor: pointer;     }      .tabstrip-tab {       padding: 5px;     }      .tabstrip-tab-hover {       border: 1px solid #316ac5;       background-color: #c1d2ee;       padding: 4px;     }      .tabstrip-tab-click {       border: 1px solid #facc5a;       background-color: #f9e391;       padding: 4px;     }   </style>  </head>   <body>    <div class="tabstrip">     <div data-tab-number="1" class="tabstrip-tab">tab1</div>     <div data-tab-number="2" class="tabstrip-tab">tab2</div>     <div data-tab-number="3" class="tabstrip-tab">tab3</div>   </div>    <div id="desccontainer"></div>    <script>     function handleevent(e) {       var target = e.target;       switch (e.type) {         case 'mouseover':           if (target.classname == 'tabstrip-tab') {             target.classname = 'tabstrip-tab-hover';           }           break;         case 'mouseout':           if (targer.classname == 'tabstrip-tab-hover') {             targer.classname = 'tabstrip-tab';           }           break;         case 'click':           if (target.classname == 'tabstrip-tab-hover') {             target.classname = 'tabstrip-tab-click';             var num = target.getattribute('data-tab-number');             showdescription(num);           }           break;       }     }      function showdescription(num) {       var desccontainer = document.getelementbyid('desccontainer')       var text = 'description tab ' + num;       desccontainer.innerhtml = text;     }      document.addeventlistener('mouseover', handleevent);     document.addeventlistener('mouseout', handleevent);     document.addeventlistener('click', handleevent);   </script>  </body>

the problem seems misspelled target targer in javascript

correct:

function handleevent(e) {   var target = e.target;   switch (e.type) {     case 'mouseover':       if (target.classname == 'tabstrip-tab') {         target.classname = 'tabstrip-tab-hover';       }       break;     case 'mouseout':       if (target.classname == 'tabstrip-tab-hover') {         target.classname = 'tabstrip-tab';       }       break;     case 'click':       if (target.classname == 'tabstrip-tab-hover') {         target.classname = 'tabstrip-tab-click';         var num = target.getattribute('data-tab-number');         showdescription(num);       }       break;   } }

codepen of working correctly
