【中文标题】同一页面上的联系表单错误消息【英文标题】:Contact form error messages on same page 【发布时间】:2015-10-27 05:01:36 【问题描述】:我有一个有效的 php 代码,但是当用户单击“发送”时,它会将他带到一个空白页面,上面写着“感谢发送”或显示错误。这是我的 php 代码和 html 表单。我希望错误和成功文本显示在第一个输入上方。我用 iframe 试过它,它工作,但我不能改变字体颜色,所以我不能真正使用它。表单位于名为inquiry.html 的HTML 文件中,而PHP 位于inquiry.php 中

【问题讨论】:
使用 ajax 请求来捕获成功或错误响应,以便稍后放置在您的 html 文档中的适当位置。 您可以尝试检查这个问题,它是使用 jquery 插件完成的。 ***.com/questions/13671710/… 你还没有在你的联系人中包含你的成功html页面 php填写它然后它会起作用 你必须使用 ajax 调用,有 jquery 或没有它 【参考方案1】:在您的联系表单中,在您的第一个输入之前添加一个 div(您希望显示结果的位置)
<div id="result"></div>
在同一个文件中添加一个包含以下内容的脚本标签
如果您已包含jQuery
$.ajax(
type: 'POST',
url: 'inquiry.php',
success: function(resp)
$("#result").text("success!");
,
error: function()
$("#result").text("error!");
);
如果你还没有 jQuery
var request = new XMLHttpRequest();
request.open('POST', 'inquiry.php', true);
request.onload = function()
if (request.status >= 200 && request.status < 400)
// Success!
var resp = request.responseText;
document.getElementById("result").textContent = resp;
else
// We reached our target server, but it returned an error
document.getElementById("result").textContent = "error!";
;
request.onerror = function()
// There was a connection error of some sort
document.getElementById("result").textContent = "error!";
;
request.send();
最后在您的inquiry.php
file 中确保您return
或echo
您想要显示的内容
