Javascript 动态改变imput type属性

Javascript 动态改变imput type属性：

代码实现：

<script type="text/javascript">
  function shoppw(thebox){
    var ps = document.getElementById(&#39;ps&#39;);
    var pass = document.getElementById(&#39;pass&#39;);
    ps.removeChild(pass);
    var psImput = document.createElement("INPUT");
     
    if(pass.type == &#39;password&#39;){
      psImput.type = "text";
    } else {
      psImput.type = &#39;password&#39;;
    }
    psImput.id = &#39;pass&#39;;
    psImput.name = "password";
    psImput.maxlength="15";
    ps.appendChild(psImput);
  }
</script>

   

HTML代码:

<td class="label"> * <label for="password" accesskey="">登录密码：</label></td>
  <td ><div id="ps"><input type="text" name="password" maxlength="15" id="pass" /></div>
   <input name="checkbox2" type="checkbox" value="true" checked="checked" id="show" onclick="shoppw(this)" />
   <label for="show" accesskey="">显示</label></td>

   

 可以运行时动态改变imput元素的type属性值
