javascript

Native js and jQuery write a carter effect comparison of web options

In general, the idea is relatively simple, that is, to get the node first, and then the corresponding processing of the node, the following is the complete page code:

Native js:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<title> native js tab</title>
<style type="text/css">
.tab{
  margin:10px auto;
  position:relative;
  width:300px;
}
ul,li{
  list-style-type:none;
  padding:0;
  margin:0;
  font:13px/20px SimSun,arial;
  color:#333;
  text-align:center;
}
.tabTltle ul li{
 float:left;
 position:relative;
 background:#fefefe;
 background:-webkit-gradient(linear,left top,left bottom, from(#fefefe), to(#ededed));
 padding:7px 15px;
 border:1px #ddd solid;
 margin-right:-1px;
 cursor:pointer;

}
.tabTltle ul li.active{
  background:#fff;
  font-weight: bold;
}
.clearfix{
}
.clearfix:after{
  display:block;
  clear:both;
  overflow:hidden;
  content:"";
}
.tabConn{
  border:1px #eee solid;
  position:relative;
  height:100px
}
.tabConn div{
  position:absolute;
  opacity:0;
  filter:alpha(opacity=0);
  padding:5px;
  text-align:center;
  width:100%;
}
.tabConn div.current{
  opacity:1;
  filter:alpha(opacity=100);
}
</style>
</head>
<body>
  <div id="tab" class="tab">
    <div class="tabTltle">
      <ul class="clearfix">
        <li class="active"> The title 1</li>
        <li> The title 2</li>
        <li> The title 3</li>
        <li> The title 4</li>
      </ul>
    </div>
    <div class="tabConn">
      <div class="current">aaaaaaaaaaaaaaa</div>
      <div>bbbbbbbbbbbbbbbbbbbbbbbbbbbbbb</div>
      <div>cccccccccccccccccccccccccccccccc</div>
      <div>ddddddddddddddddddddddddddddd</div>
    </div>
  </div>
<script type="text/javascript">
 (function(){
   var tab = document.getElementById("tab");
   var tabList = tab.getElementsByTagName("div")[0].getElementsByTagName("li");
   var tabConn = tab.getElementsByTagName("div")[1].getElementsByTagName("div");for(var i=0;i<tabList.length;i++){
    tabList[i].index = i;
    tabList[i].onclick = function(){
      showConn(this.index);
    }
  }
  function showConn(_index){
    var index = _index;for(var j=0;j<tabList.length;j++){
      tabList[j].className = "";
      tabConn[j].className = "";
      tabConn[j].style.opacity=0;
    }
    tabConn[index].className="current";
    tabList[index].className="active";
  }
 })();
</script>
</body>
</html>

Let’s take a look at what jQuery wrote (css Shared, need to introduce jQuery library) :

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<title>jQuery tab</title>
<script type="text/javascript" src="js/jquery-1.8.1.min.js"></script>
<style type="text/css">
.tab{
 margin:10px auto;
 position:relative;
 width:300px;
}
ul,li{
 list-style-type:none;
 padding:0;
 margin:0;
 font:13px/20px SimSun,arial;
 color:#333;
 text-align:center;
}
.tabTltle ul li{
 float:left;
 position:relative;
 background:#fefefe;
 background:-webkit-gradient(linear,left top,left bottom, from(#fefefe), to(#ededed));
 padding:7px 15px;
 border:1px #ddd solid;
 margin-right:-1px;
 cursor:pointer;

}
.tabTltle ul li.active{
 background:#fff;
 font-weight: bold;
}
.clearfix{
}
.clearfix:after{
 display:block;
 clear:both;
 overflow:hidden;
 content:"";
}
.tabConn{
 border:1px #eee solid;
 position:relative;
 height:100px
}
.tabConn div{
 position:absolute;
 opacity:0;
 filter:alpha(opacity=0);
 padding:5px;
 text-align:center;
 width:100%;
}
.tabConn div.current{
 opacity:1;
 filter:alpha(opacity=100);
}
</style>
</head>
<body>
<h3>jQuery Write tabs :</h3>
 <div id="tab2" class="tab">
  <div class="tabTltle tab-title">
   <ul class="clearfix">
    <li class="active"> The title 1</li>
    <li> The title 2</li>
    <li> The title 3</li>
    <li> The title 4</li>
   </ul>
  </div>
  <div class="tabConn tab-conn">
   <div class="current">aaaaaaaaaaaaaaa</div>
   <div>bbbbbbbbbbbbbbbbbbbbbbbbbbbbbb</div>
   <div>cccccccccccccccccccccccccccccccc</div>
   <div>ddddddddddddddddddddddddddddd</div>
  </div>
 </div>
<script type="text/javascript">
$(document).ready(function(){
 var $tabTitle = $('.tab-title').find('li');
 var $tabList = $('.tab-conn > div');
 $tabTitle.click(function(){
  $tabTitle.each(function(){
   $tabTitle.removeClass('active');
  });
  var index = $tabTitle.index(this);
  $(this).addClass('active');
  $tabList.eq(index).addClass('current').siblings().removeClass('current');
 });
});
</script>
</body>
</html>

Is not a lot easier!

That’s all for this article, I hope you enjoy it.
