--- JS 和 AJAX 代码 ---

if (!e.isDefaultPrevented()) {
var url = "contact.php";
$.ajax({
type: "POST",
url: url,
data: $(this).serialize(),
success: function (data) {
var messageAlert = 'alert-' + data.type;
var messageText = data.message;
var alertBox = '<div class="alert ' + messageAlert + ' alert-dismissable"><button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>' + messageText + '</div>';
if (messageAlert && messageText) {
$('#contact-form').find('.messages').html(alertBox);
$('#contact-form')[0].reset();
}
}
});
return false;
}
})
});
【问题讨论】:
-
您是否加载了 javascript 文件,如果是,您能告诉我们在哪里以及如何加载吗?
-
请解释一下 -> “但是在同一页面上看不到成功消息。它看到另一个页面。” 你的意思是你去不同的页面?如果有,是哪一页?
-
@Archer 是的,你是对的。它将发送至websitename.com/contact.php 在该页面上,我看到“感谢您的留言。我会尽快回信。”
-
我认为 @RickJelier 是正确的 - 检查您是否正确包含了 javascript。如果有疑问,只需在其中的某处放置一个提醒,当您访问该页面时应该会显示。
-
@Archer JS 文件已正确添加,但可以看到重定向页面的警报。我不想重定向以显示警报。警报必须与联系表单在同一页面上。
