MessageBox带有yes no或取消按钮 [英] MessageBox with yes no or cancel button

问题描述

<script type = "text/javascript">

    function Confirm()
    {
        var confirm_value = document.createElement("INPUT");
        confirm_value.type = "hidden";
        confirm_value.name = "confirm_value";
        if (confirm("Do you want to save data?")) {
            confirm_value.value = "Yes";
        } else {
            confirm_value.value = "No";
        }
        document.forms[0].appendChild(confirm_value);
    }

</script>

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1" ErrorMessage="*" ForeColor="Red"></asp:RequiredFieldValidator>
<asp:TextBox ID="TextBox1" runat="server" BackColor="White" BorderColor="White" 
BorderStyle="Groove" Width="157px"></asp:TextBox>
<br />
<br />
<asp:Button ID="Button1" runat="server" style="font-size: medium; font-weight: 700; font-style: italic" Text="Submit" onclick="Button1_Click" OnClientClick="Confirm()" />

I am using this code when click on Submit Button MessageBox is appear but it does not check Required Field Validator.

推荐答案

我想你想在必要的字段验证器验证输入后显示消息框。

从onClientClick调用它的表单的onsibmit调用Confirm（）函数。

如下所示对代码进行一些更改;

I think you want to show the message box after required field validater validates the input.
Call the Confirm() function from onsibmit of the form instaed of calling it from onClientClick.
Do a little change in your code as below;

<form id="form1" runat="server" onsubmit="Confirm()><br mode=" hold=" /></form></pre><br mode="></form>
