[英]jQuery.post() send email but doesn't gets to .done()/.fail()/.always() without server refresh
I'm trying to basically just send a form information to e-mail without having to refresh the page and I came all the way to this.我试图基本上只是将表单信息发送到电子邮件而无需刷新页面,我一路走到了这一步。 The issue here is, that even though it sends the email correctly, it doesn't clear the form because the $.post() never gets to the .done() or .fail() or .always().
这里的问题是,即使它正确发送了电子邮件,它也不会清除表单,因为 $.post() 永远不会到达 .done() 或 .fail() 或 .always()。 Although I noticed that as I work with nodemon when I change the code and save it, it refreshes the server and then it gets to .fail() and .always() but never to .done().
尽管我注意到当我更改代码并保存它时使用 nodemon 时,它会刷新服务器,然后它会到达 .fail() 和 .always(),但永远不会到达 .done()。
do you guys know what should I do to make the $.post() get correctly to done/fail/always, please?你们知道我应该怎么做才能使 $.post() 正确完成/失败/总是吗?
code looks like this:代码如下所示:
HTML HTML
<form class="trial-form" action="/trial-submission" method="post">
<input id="company" type="text" name="company" placeholder="Company" />
<input id="person" type="text" name="person" placeholder="Contact person" />
<input id="phone" type="tel" name="telephone" placeholder="Phone" />
<input id="email" type="email" name="mailAddress" placeholder="E-mail" />
<input id="note" type="text" name="note" placeholder="Note" />
<button class="blue-button" id="submit-trial" type="button">send</button>
</form>
JavaScript JavaScript
$(document).ready(function(){
$("#submit-trial").click(function(event){
let cmpn = $("#company").val();
let eml = $("#email").val();
let phn = $("#phone").val();
let nt = $("#note").val();
let prsn = $("#person").val();
$.post("/trial-submission", {
company: cmpn,
person: prsn,
phone: phn,
email: eml,
note: nt
})
.done(function(){
$("#company").val("");
$("#email").val("");
$("#phone").val("");
$("#note").val("");
$("#person").val("");
alert("success");
})
.fail(function(){
alert("error");
})
.always(function(){
alert("finished");
});
});
});
and the node stuff is here节点的东西在这里
app.post("/trial-submission", function(req, res){
const data = req.body;
let transporter = nodemailer.createTransport({
service: "mail",
auth: {
user: "send@mail.com",
pass: "password"
}
});
let mailOptions = {
from:'send@mail.com',
to:'receive@mail.com',
subject: 'testing',
html:`
Company: ${data.company}<br>
Contact person: ${data.person}<br>
Phone: ${data.phone}<br>
E-mail: ${data.email}<br>
Note: ${data.note}
`
};
transporter.sendMail(mailOptions, function(err, data){
if(err){
console.log('Error Occurs', err);
} else {
console.log('Email Sent!');
}
});
});
You need to send a response in your sendMail call, otherwise your browser never receives anything.你需要在你的 sendMail 调用中发送一个响应,否则你的浏览器永远不会收到任何东西。 Try this:
尝试这个:
transporter.sendMail(mailOptions, function(err, data){
if(err){
console.log('Error Occurs', err);
res.sendStatus(400);
} else {
console.log('Email Sent!');
res.sendStatus(204);
}
});
The 400 is a simple "Bad Request", and the 204 is "Success/No Content". 400 是一个简单的“错误请求”,而 204 是“成功/无内容”。 You can modify these further, but for now the responses will be received by the client so you can proceed.
您可以进一步修改这些,但现在客户端将收到响应,因此您可以继续。
