Question

我正在为大学制作一个网站，我需要在其中加入JavaScript，所以当我点击CSS中的“提交”按钮时我想出现一个弹出框，但我并不完全确定怎么做。目前我已经为弹出框提供了以下JavaScript：

<button onclick="SubmitBtn">Hello</button>
<script>
function myFunction() {
    alert("Your email has been sent!");
}
</script>

然而，它只是创建另一个按钮而不起作用。我不擅长使用JavaScript，因为我几周只做了这些，所以任何帮助都会非常感激。我想要按下的按钮位于页面底部的表格中。

我将完整的代码放在下面没有CSS：

<!DOCTYPE html>
<html>
<head>

</body>
</html>

<button onclick="SubmitBtn">Hello</button>

<script>
function myFunction() {
    alert("Your email has been sent!");
}
</script>

<title>OINK - Contact Us</title>
<body>
<div id="container">
<center><p>WELCOME TO THE OINK LAYOUT!</p></center></font>
<div id="menu">
<ul>
<center>
<li><a class="button_example" href="index.html">HOME</a></li>
<li><a class="button_example" href="piggybanks.html">PIGGY BANKS</a></li>

<li><a class="button_example" href="pigtures.html">PIGTURES</a></li>
</center>
</ul>
<p>&nbsp;</p>
<p>&nbsp;</p>

<div>

  <!-- <div id="footer">This is the footer</div> -->
</div>

<form id="form1" name="form1" method="post" action="#" onsubmit="return checkform(this);">

  <input type="text" name="Email" id="Email" />

  <textarea name="Message" id="Message" cols="45" rows="5"></textarea>
  <input type="submit" name="SubmitBtn" id="SubmitBtn" value="Submit" />
</form>

Answer 1

试试这个

<button onclick='foo();'>Hello</script>
<script>
function foo(){
 alert('Your email has been sent');
}
</script>

Answer 2

您可以检索from并覆盖onsubmit函数：

<script>
var form = document.forms.SubmitBtn;

form.onsubmit = function(){
    alert("Your email has been sent!");
    return true;
}
</script>

这应该有用。
