        var tab=document.getElementById("tab");
        var n=document.getElementById("x").rowIndex+1;

<div id="zw1" style="margin-bottom : 60px; margin-top:10px;" >                            <li class="horizontal_onlyRight" style="margin-top:10px;">                            <input name="zw11" class="text_input100" id="zw11" onkeyup="tihuan(this)" value="">                                 </li>                          </div>

1、innerHTML写入html代码方法，是原生态JS方法：
<div id="box"></div>
<script>document.getElementById("box").innerHTML="需要像box内写入的内容"</script>
2、append()是jQuery中的方法，需要先引用jQuery库代码。
<div id="box"></div>
<script>
$("#box").append("需要像box内写入的内容");
</script>
