[英]Call javascript in between a button OnClick event in C#
I have a button with OnClick event on my web page. 我的网页上有一个带有OnClick事件的按钮。
<asp:TextBox ID="tbMailID" runat="server" Width="250px"></asp:TextBox>
<asp:Button ID="btnSubmit" runat="server" OnClick="btnSubmit_Click" Text="Submit" />
C# code: C#代码:
protected void btnSubmit_Click(object sender, EventArgs e)
{
bool IsGmail = CheckMailId(tbMailID.Text);
if(!IsGmail)
{
string strScript = "confirm('Mail id is not from gmail, do you still want to continue?');";
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "strScript", strScript, true);
}
SendMail();
}
The page accepts a mail id in textbox and on submit sends a mail. 该页面在文本框中接受邮件ID,并在提交时发送邮件。 But if mail-id is not an gmail id (validated by CheckMailId) i want to show a confirmation box to user whether he/she wants to get a mail, based on the Yes/No clicked. 但是,如果mail-id不是gmail id(由CheckMailId验证),则我想根据是/否单击向用户显示一个确认框,以确认他/她是否要接收邮件。
But the javascript will get call after the submit event is served and mail is sent. 但是javascript会在提供Submit事件并发送邮件后得到调用。 if i add a return SendMail() will never get calls 如果我添加一个返回SendMail()将永远不会收到电话
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "strScript", strScript, true);
return;
What could be a possible solution here? 这里有什么可能的解决方案?
Note: the code posted is simplified version of my real use case. 注意:发布的代码是我实际用例的简化版本。 CheckMailId - is just a name to show, it calls up many other functions and do few db process. CheckMailId-只是要显示的名称,它调用了许多其他功能,并且很少执行数据库进程。 So incorporating that in javascript, i would like to avoid. 因此,将其合并到javascript中,我想避免。
You can call a script befroe event lke this:- 您可以这样调用脚本事件:-
<script type="text/javascript">
function Confirm() {
var yourstring = document.getElementById('<%= tbMailID.ClientID %>').value;
if (/@gmail\.com$/.test(yourstring)) {
return true;
}
else
{
if (confirm("Mail id is not from gmail, do you still want to continue?") == true)
return true;
else
return false;
}
}
</script>
strong text 强文本
<asp:Button ID="btnSubmit" runat="server" OnClientClick="return Confirm();" OnClick="btnSubmit_Click" Text="Submit" />
