我创建了一个包含html和php代码的Web php网页，请参见下文。
提交表单时，它会向我发送电子邮件，并显示一条成功失败消息。因此，一切正常。
我的问题：我想弹出成功或失败消息或成为模式消息，但我不知道如何做。我应该在哪里更改代码并添加模态？
我的顶部是php，然后是HTML表单。我的表单还具有Google Recaptcha验证工具。我只想添加一个模式，但是我不知道如何以及在哪里添加代码。

我的目的是单击提交按钮，然后弹出一个带有成功或失败消息的模式。
答案 0 :(得分：0)
如果要将模式用作信息消息，请将模式放在body标记后的html内，然后在事件成功或失败后使用javascript对其进行调用。
用于模式的JavaScript：$('#myModal').modal(options)。
或者，如果您希望使用更简单的方法，则可以使用JavaScript alert()通知事件成功或失败

我对代码做了很少的更改。我包括了引导程序模式代码和javascript函数来调用弹出窗口。检查此代码。

您可以创建一个隐藏字段，例如：
<input type="hidden" name="msg" id="msg" value="<?php echo $msg ?>">
然后在准备就绪的文档上使用JQuery：
$(document).ready(function() {
if($('#msg').val() != "")
{
alert($('#msg').val()); // or replace with a JQuery modal
}
});
