I’m making an application where when I click a button I have to send an email. I got my page one input type=Text and a button type="button" that with css got like this ->.
I need that when I press this arrow, an email be sent as it is in the code, and in the body of email also be sent what is in the input text. If the input text is empty, it must error and do nothing.

I click the button but do nothing. What may be going wrong?

Code I have for now:

The problem is that you are trying to call an ASP function in the event OnClick() Javascript. One does not see the other because ASP runs on the server and Javascript runs on the user’s browser.

Suggestion

Modify the type of the button element <button type="button"..., defining with the type Submit <button type="submit"...

This topic can be interesting to know more: Button element submitting form. How to disable?

Also set the attribute action of the element <form>

<form class="lockscreen-credentials" action="pagina.aspx" method="post">

The.Asp page file is where you should have the script you posted

 public void SendEmail()
  {


      try
      {

          SmtpClient cliente = new SmtpClient();
          cliente...

Runat=server

If you want to use with attribute runat="server":

<button type="button" class="btn" onclick="SendEmail()" runat="server">

Exchange for:

<asp:Button id="SendEmail" runat="server" UseSubmitBehavior="false" EnableViewState="false" class="btn" onclick="SendEmail">

  • Already modei but still does not execute the code or send the email.

  • guy does post but is not sending email no.

  • That’s another problem. The main question was to do Ubmit, already solved. So there’s nothing more to comment on. Avoid asking several things in a single topic. Ask one question and solve it. When you have another question / problem, open a new topic. Read the rules of the site: http://answall.com/tour.
