推荐答案

您可以使用另一个文本框在其中显示密码框的值.最初将文本框放在passwordBox下方，并且visible = hidden.
您的密码箱的onblur事件，隐藏密码箱并显示具有密码箱init值的可见文本框.
即

Hi,
you may use another textbox to show password box value into it. intially place the text box beneath your passwordBox and visible = hidden.
onblur event of your passwordbox, hide password box and display visible textbox with having value of passwordbox init.
i.e

<form id="form1" runat="server">
    <div>
        <asp:textbox textmode="Password" id="txtPass" runat="server" onblur="ShowPasswordEntered()" xmlns:asp="#unknown" />
    </div>
    </form>

<script type="text/javascript">
    function ShowPasswordEntered() {
        var passString = document.getElementById("txtPass").value;
        alert(passString);
    }
</script>

您说:但它从服务器端得到响应:"

您是否实际上已经使用适当的工具检查了服务器端的响应?该响应是什么样的:它是否提供任何线索，错误消息?您是否有可能说您没有从服务器获得响应?

如果出于某些有机"原因，您不应该在运行时在ASP.NET中更改TextBox上的TextMode属性，请考虑:有两个具有相同大小和位置的TextBox，其中一个设置为Textmode"Password"， '设置为TextMode的"SingleLine"模式，然后根据需要切换z顺序?

You say: "but it get response from the server side:"

Have you actually examined the server-side response with an appropriate tool ? What does that response look like: does it give you any clue, any error message ? Is it possible you meant to say you are not getting a response from the server ?

If there is some ''organic'' reason you should not change the TextMode property on a TextBox at run-time in ASP.NET, then consider: have two TextBoxes with identical size and location, one set to Textmode ''Password,'' one set to TextMode ''SingleLine'' mode, and then just switch the z-order as necessary ?
