    {
        document.getElementById("Confirm").value="";
    }
    return true;

推荐答案

这样的事情：

Something like this:

function deleteConfirmPasswordText()
{
    if(document.getElementById("txtPassword").value == "") {
        document.getElementById("txtConfirmPassword").value = "";
    }
    return false;
}

<asp:TextBox ID="txtPassword" runat="server" TextMode="Password"></asp:TextBox>
<asp:TextBox ID="txtConfirmPassword" runat="server" TextMode="Password"></asp:TextBox>
<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClientClick="return deleteConfirmPasswordText();" />

注意：return false是因为如果密码文本框为空，表单不应发布。你必须在客户端和服务器端都有这些验证。



希望这有帮助！

Note: return false is because the form shouldn't post if the password text box is empty. You must have these validations in place, both at client side and server side.

Hope this helps!

你需要将文本框文本属性设置为null或。

You need to set the textbox text property to null or "".
