        .nav{border: 5px blue solid;float: left}
        .left{float:left;margin:30px;border:3px red solid;width: 300px;height: 200px;}
        .right{float: left;margin: 30px;border:3px black solid;width:300px;height: 200px;}
        button{position:relative;top: 30px;float: left;}

<body>
<div class="nav">
   <textarea class="left"></textarea>
    <button>文字右移</button>
    <textarea class="right"></textarea>
</div>
<script>
    window.onload=function () {
        var textLeft=document.getElementsByClassName("left")[0];
        var textRight=document.getElementsByClassName("right")[0];
        var button=document.getElementsByTagName("button")[0];
        button.onclick=function () {
            textRight.value+=textLeft.value;
            textLeft.value="";
        }
    }
</script>
</body>
</html>
