更改TextMode属性 [英] change the TextMode property

问题描述

我想知道如何在javascript中更改TextMode asp文本框属性(单行，多行，密码).是否有可能.

I would like to know how to change the TextMode asp textbox property (Singleline,multiline,password)in javascript.Is there any possibility.

推荐答案

尝试一下
Javascript

Try this
Javascript

<script type="text/javascript">
       function test() {
           document.getElementById('<%= txt.ClientID %>').type = 'password';
       }
   </script>

设计部分

Design Part

<asp:TextBox ID="txt"  runat="server" TextMode="SingleLine"></asp:TextBox>
 <div  onclick="test();" >click</div>

这是解决方案，

Here is the solution,

<div>
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</div>
<script type="text/javascript">
    var obj = document.getElementById("TextBox1");
    var newObj = document.createElement(''input'');
    newObj.setAttribute(''type'', ''password'');
    newObj.setAttribute(''id'', obj.getAttribute(''id''));
    newObj.setAttribute(''name'', obj.getAttribute(''name''));
    obj.parentNode.replaceChild(newObj, obj);
    newObj.focus();
</script>

基本思想是用所需的文本模式创建一个新元素，然后用新的替换原来的元素.

希望这会有所帮助.

The basic idea is to create a new element with your desired textmode and replace the original with the new one.

Hope this helps.
