在asp.net C中按钮点击chk验证＃ [英] chk validation on button click in asp.net C#
问题描述
HI专家，
我有一个注册网页，在这个网页上我有3个文本框和一个提交按钮。
我正在使用用于在数据库中插入这些值的Sqlserver 2005数据库。
当我点击提交按钮时，这些值正在成功存储。
到此为止，它工作正常。
现在我的要求是，
如果我点击提交，文本框是空，它必须显示一条消息，请输入必填字段。
如果文本框中填充了数据，那么当我点击提交按钮时，应该显示。< br $> b $ b
你确定要提交这些数据吗？
如果成功存储在数据库中，显示消息....已成功提交。
请帮助我，我很困惑，谢谢。

Try this

<script type="text/javascript">
function Validate() {
var txt1 = document.getElementById('TextBox1');
var txt2 = document.getElementById('TextBox2');
var txt3 = document.getElementById('TextBox3');
if(txt1.value == '' || txt2.value == '' || txt3.value == '')
{
alert('please enter value');
return false;
}
else
{
return confirm('Do you want to continue')
}
}
</script>
</head>
<body>
<asp:textbox runat="server" txt="valid" id="TextBox1" xmlns:asp="#unknown"></asp:textbox>
<asp:textbox runat="server" txt="valid" id="TextBox2" xmlns:asp="#unknown"></asp:textbox>
<asp:textbox runat="server" txt="valid" id="TextBox3" xmlns:asp="#unknown"></asp:textbox>
<asp:button runat="server" id="btnSubmit" text="save" xmlns:asp="#unknown">
OnClientClick="javascript:return Validate()" onclick="btnSubmit_Click" />/<body></body></asp:button></body>
空白字段验证代码：
Code for blank field validations:
<asp:textbox id="TextBox1" value="" xmlns:asp="#unknown"></asp:textbox>
<asp:requiredfieldvalidator id="RequiredFieldValidator3" runat="server" errormessage="" forecolor="red" controltovalidate="TextBox1" validationgroup="A" initialvalue="" xmlns:asp="#unknown">*</asp:requiredfieldvalidator>
<asp:textbox id="TextBox2" textmode="Password" value="" xmlns:asp="#unknown"></asp:textbox>
<asp:requiredfieldvalidator id="RequiredFieldValidator4" runat="server" errormessage="" forecolor="red" controltovalidate="TextBox2" validationgroup="A" initialvalue="" xmlns:asp="#unknown">*</asp:requiredfieldvalidator>
<asp:button id="btn_submit" runat="server" text="Submit" onclick="btn_submit_Click" onclientclick="return confirm('Are you sure you want to enter details?');" validationgroup="A" xmlns:asp="#unknown" />
输入详细信息的代码：
Code for entering details:
protected void btn_submit_Click(object sender, EventArgs e)
{
//You code here
Response.Write("<script type='text/javascript'>");
Response.Write("alert('Your details has been submitted successfully.');");
Response.Write("</script>");
}
