I was wondering if it is possible to email a value which is returned by a function in javascript?
我想知道是否可以 email 一个由 javascript 中的 function 返回的值？ or do i have to use php/ajax?还是我必须使用 php/ajax？
From the following example, I want to email abc to myself?从下面的例子中，我想把 email abc 给自己？ How can it be done?怎么做到呢？
<html>
<head><script>
var t = "abc";
function test(){
return t;}

You'll need to post it to your server via XHR, then your server can email it.您需要通过 XHR 将其发布到您的服务器，然后您的服务器可以 email 它。

There's no direct method.没有直接的方法。 I would use jQuery' $.post to post the relevant information to a PHP page which would then mail it using, at it's simplest, the aptly-named mail function.我会使用 jQuery 的$.post将相关信息发布到 PHP 页面，然后使用最简单的命名邮件function 将其邮寄。
In one of the script tags of the main page or in a separate.js file:在主页的脚本标记之一或单独的 .js 文件中：
$.post("mailer.php", {data: "abc"}, function(data) {
// Alert yourself whether it was successful if you want
});
And mailer.php (replace these with your own values):和 mailer.php （用您自己的值替换这些）：
<?php
$to = 'nobody@example.com';
$subject = 'the subject';
$message = $_POST['data'];
$headers = 'From: webmaster@example.com';
mail($to, $subject, $message, $headers);
?>

Here is a very good explanation from another similar question :这是另一个类似问题的一个很好的解释：
You can't send an email with javascript , the closest you can get would be a mailto which opens the default email client - but that won't send anything.
Email should be sent from the server - submit the form in the normal way, and construct the email on the server and send it....
Another answer there gives some details about using mailto .那里的另一个答案提供了有关使用mailto的一些详细信息。
