我的联系表单正在运行，但成功消息并未显示。另一位开发人员编写了PHP代码但我做了一些jQuery并且它不会显示我的消息。我很确定问题出在jQuery上。我对这行代码感到特别困惑......
$("#result").hide().html(output).slideDown();
}, 'json');
}
我认为你会想要使用.show（），因为需要#result才能显示html，但似乎并没有这样做。完整代码如下。
$(function(){
$(".btn").click(function() {
//get input field values
var user_name = $('input[name=name]').val(),
user_email = $('input[name=email]').val(),
user_message = $('textarea[name=message]').val(),
proceed = true;
//simple validation at client's end
//we simply change border color to red if empty field using .css()
if(user_name===""){
$('input[name=name]').css('border','2px solid red').after('<p class="error-msg">(What\'s your name?)</p>');
proceed = false;
}
if(user_email===""){
$('input[name=email]').css('border','2px solid red').after('<p class="error-msg">(Please provide a valid email)</p>');
proceed = false;
}
if(user_message==="") {
$('textarea[name=message]').css('border','2px solid red').after('<p class="error-msg">(Please let me know what your inquiry is about)</p>');
proceed = false;
}
//everything looks good! proceed...
if(proceed)
{
//data to be sent to server
post_data = {'userName':user_name, 'userEmail':user_email, 'userMessage':user_message};
//Ajax post data to server
$.post('../../contact-form.php', post_data, function(response){
//load json data from server and output message
if(response.type === 'error')
{
output = '<div class="error">'+response.text+'</div>';
}else{
output = '<div class="success">'+response.text+'</div>';
alert('Thanks for the message');
//reset values in all input fields
$('.form-container input').val('');
$('.form-container textarea').val('');
}
$("#result").hide().html(output).slideDown();
}, 'json');
}
});
//reset previously set border colors and hide all message on .keyup()
$(".form-container input, .form-container textarea").keyup(function() {
$(".form-container input, .form-container textarea").css('border-color','');
$("#result").slideUp();
});
});
PHP代码
<?php
if($_POST)
{ $ to_Email =＆＃34; alexechaparro@gmail.com" ;; //替换收件人电子邮件地址 $ subject =＆＃39; alexsdogvacay.com＆＃39 ;; //电子邮件的主题行
//check if its an ajax request, exit if not
if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {
//exit script outputting json data
$output = json_encode(
array(
'type'=>'error',
'text' => 'Request must come from Ajax'
));
die($output);
}
var_dump($_REQUEST);
//check $_POST vars are set, exit if any missing
if(!isset($_POST["userName"]) || !isset($_POST["userEmail"]) || !isset($_POST["userMessage"]))
{
echo $_POST["userName"];
$output = json_encode(array('type'=>'error', 'text' => 'Input fields are empty!'));
die($output);
}
//Sanitize input data using PHP filter_var().
$user_Name = filter_var($_POST["userName"], FILTER_SANITIZE_STRING);
$user_Email = filter_var($_POST["userEmail"], FILTER_SANITIZE_EMAIL);
$user_Message = filter_var($_POST["userMessage"], FILTER_SANITIZE_STRING);
//additional php validation
if(strlen($user_Name)<4) // If length is less than 4 it will throw an HTTP error.
{
$output = json_encode(array('type'=>'error', 'text' => 'Name is too short or empty!'));
die($output);
}
if(!filter_var($user_Email, FILTER_VALIDATE_EMAIL)) //email validation
{
$output = json_encode(array('type'=>'error', 'text' => 'Please enter a valid email!'));
die($output);
}
if(strlen($user_Message)<5) //check emtpy message
{
$output = json_encode(array('type'=>'error', 'text' => 'Too short message! Please enter something.'));
die($output);
}
//proceed with PHP email.

所以，令人困惑的代码行：$('#result').hide().html().slideDown();有效。无需改变它。我看到的一个问题是，您的变量output未被var定义，使其成为全局变量。
除此之外，php代码似乎使用die函数杀死了成功响应，但是它并没有向输出返回任何内容。改变这个：
if(!$sentMail)
{
$output = json_encode(array('type'=>'error', 'text' => 'Could not send mail! Please check your PHP mail configuration.'));
die($output);
}else{
$output = json_encode(array('type'=>'message', 'text' => 'Hi '.$user_Name .' Thank you for your email. I will get back to you as soon as possible.'));
die($output);
}
TO：
if(!$sentMail)
{
$output = json_encode(array('type'=>'error', 'text' => 'Could not send mail! Please check your PHP mail configuration.'));
}else{
$output = json_encode(array('type'=>'message', 'text' => 'Hi '.$user_Name .' Thank you for your email. I will get back to you as soon as possible.'));
}
echo $output;
希望这有帮助！

这是我第二次因为我的HTML而被烧毁。以前我的HTML是......
<form id="contact_form">
<div id="result"></div>
<div class="form-group">
<label for="name" id="name">Name</label>
<input type="text" name="name" class="form-control" id="exampleInputName" placeholder="Name" required>
</div>
<div class="form-group">
<label for="Email" id="email">Email address</label>
<input type="email" name="email" class="form-control" id="exampleInputEmail1" placeholder="Email" required>
</div>
<div class="form-group">
<label for="Message" id="message">Message</label>
<textarea rows="4" name='message'class="form-control" placeholder="Message" required></textarea>
</div>
<div><span> </span>
<input type="button" class="btn btn-default" id='submit_btn' value="Submit">
</div>
</form>
我所做的就是将我的表单更改为字段集并输入
<button class="btn btn-default" id="submit_btn">Submit</button>
老实说，我不确定为什么要修复它，但确实如此。
