我在html中有一个非常简单的表单,我正在尝试发送电子邮件。我在网上查了一些教程唱歌js,但大多数都不能正常工作。这是我的代码表单,但是当我按下提交时,js function
没有被调用,而是在html表单上没有做任何事情。
<form class="form-inline" id="contact-form" onSubmit="return false">
<center><p><input style="height:3vw;width:40vw;font-size:1.2vw;" type="text" class="form-control" size="30" placeholder=" Name" name="name" id="name" required></p>
<p><input style="height:3vw;width:40vw;font-size:1.2vw;" type="email" class="form-control" size="30" placeholder=" E-mail Address" name="email" id="email" required></p>
<p><input style="height:3vw;width:40vw;font-size:1.2vw;" type="text" class="form-control" size="30" placeholder=" Subject" name="subject" id="subject" required></p>
<p><textarea style="height:10vw;width:40vw;font-size:1.2vw;" placeholder=" Message..." class="form-control" name="message" id="message"></textarea></p>
<p><button type="submit" class="button" name="btn_submit" id="btn_submit">Send</button></p></center>
</form>
我已经在表单的<div>
结尾之后包含了js文件
<script src="js/jquery-2.1.4.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="js/functions.js"></script>
functions.js
文件如下
//Contact Us
$("#btn_submit").click(function() {
//get input field values
var user_name = $('input[name=name]').val();
var user_email = $('input[name=email]').val();
var user_message = $('textarea[name=message]').val();
//simple validation at client's end
var proceed = true;
if(user_name==""){
proceed = false;
}
if(user_email==""){
proceed = false;
}
if(user_message=="") {
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_me.php', post_data, function(response){
//load json data from server and output message
if(response.type == 'error')
{
output = '<div class="alert-danger">'+response.text+'</div>';
}else{
output = '<div class="alert-success">'+response.text+'</div>';
//reset values in all input fields
$('.form-inline input').val('');
$('.form-inline textarea').val('');
}
$("#result").hide().html(output).slideDown();
}, 'json');
}
});
我的电子邮件处理程序如下:
<?php
if($_POST)
{
$to_Email = "email.com"; //Replace with recipient email address
//check if its an ajax request, exit if not
if(!isset($_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);
}
//check $_POST vars are set, exit if any missing
if(!isset($_POST["userName"]) || !isset($_POST["userSubject"]) || !isset($_POST["userEmail"]) || !isset($_POST["userMessage"]))
{
$output = json_encode(array('type'=>'error', 'text' => 'Input fields are empty!'));
die($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);
$user_Subject = filter_var($_POST["userSubject"], FILTER_SANITIZE_STRING);
$user_Message = filter_var($_POST["userMessage"], FILTER_SANITIZE_STRING);
//additional php validation
if(strlen($user_Name)<3) // If length is less than 3 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);
}
$subject = $user_Subject;
$message_Body = "<strong>Name: </strong>". $user_Name ."<br>";
$message_Body .= "<strong>Email: </strong>". $user_Email ."<br>";
$message_Body .= "<strong>Message: </strong>". $user_Message ."<br>";
$headers = "From: " . strip_tags($user_Email) . "\r\n";
$headers .= "Reply-To: ". strip_tags($user_Email) . "\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
//proceed with PHP email.
/*$headers = 'From: '.$user_Email.'' . "\r\n" .
'Reply-To: '.$user_Email.'' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
*/
$sentMail = @mail($to_Email, $subject, $message_Body, $headers);
if(!$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 contacting us.'));
die($output);
}
}
?>
在按下提交时,没有调用js文件,控制台也没有错误。任何人都可以帮我解决我犯错误的地方。谢谢。

您需要阻止默认表单提交操作,即刷新页面。
您需要在函数中添加一个可以跟踪事件的参数,然后从该参数中调用preventDefault()
:
$("#btn_submit").click(function(e) {
e.preventDefault();
...
}

尝试替换
length-1
与
$("#btn_submit").click(function() {
答案 2 :(得分:0)
您需要阻止表单提交,否则它将直接提交并转向服务器端。
你可以使用jQuery做这样的事情:
$("#btn_submit").click(function(e) {
e.preventDefault();
//your code goes here after preventing submission
}
