<body> 
<form onsubmit="return validate()"> 
<!-- contact form content--> 
<input type="submit" value="submit" name="submit" /> 
</form> 
</body> 
</html>

Answer 1

您的代码中没有div ...您需要标识要隐藏的表单=>添加ID

<form onsubmit="return validate()" id="myID">

或添加一个包装表格的div

<div id="myID">
  <form onsubmit="return validate()"> 
    <!-- contact form content--> 
    <input type="submit" value="submit" name="submit" /> 
  </form>
</div>

然后通过选择ID隐藏表单或div：

document.getElementById("myID").style.display="none";

Answer 2

如果有人关闭了javascript会怎样？ 为什么不决定用if显示-php中的else？

<?php
if(mail($to,$subject,$body,$headers)) 
{
    echo "We have received your enquiry. We will contact you soon."; 
} 
else
{
?>
    <form onsubmit="return validate()"> 
        <!-- contact form content--> 
        <input type="submit" value="submit" name="submit" /> 
    </form> 
<?php
}
?>
