发送电子邮件的html按钮

Question

How do I send an email with specified initial values for the headers subject and message from a button in html, such as this

<form method="post" action="mailto:email.com?subject=subject&message=message">

where subject and message are values fetched from a form ?

Answer 1

You can use mailto , here is the HTML code:

<a href="mailto:EMAILADDRESS">

Replace EMAILADDRESS with your email.

Answer 2

This method doesn't seem to work in my browser, and looking around indicates that the whole subject of specifying headers to a mailto link/action is sparsely supported, but maybe this can help...

HTML:

<form id="fr1">
    <input type="text" id="tb1" />
    <input type="text" id="tb2" />
    <input type="button" id="bt1" value="click" />
</form>

JavaScript (with jQuery):

$(document).ready(function() {
    $('#bt1').click(function() {
        $('#fr1').attr('action',
                       'mailto:test@test.com?subject=' +
                       $('#tb1').val() + '&body=' + $('#tb2').val());
        $('#fr1').submit();
    });
});

Notice what I'm doing here. The form itself has no action associated with it. And the submit button isn't really a submit type, it's just a button type. Using JavaScript, I'm binding to that button's click event, setting the form's action attribute, and then submitting the form.

It's working in so much as it submits the form to a mailto action (my default mail program pops up and opens a new message to the specified address), but for me (Safari, Mail.app) it's not actually specifying the Subject or Body in the resulting message.

HTML isn't really a very good medium for doing this, as I'm sure others are pointing out while I type this. It's possible that this may work in some browsers and/or some mail clients. However, it's really not even a safe assumption anymore that users will have a fat mail client these days. I can't remember the last time I opened mine. HTML's mailto is a bit of legacy functionality and, these days, it's really just as well that you perform the mail action on the server-side if possible.

Answer 3

As David notes , his suggestion does not actually fulfill the OP's request, which was an email with subject and message . It doesn't work because most, maybe all, combinations of browsers plus e-mail clients do not accept the subject and body attributes of the mailto: URI when supplied as a <form> 's action .

But here's a working example:

HTML (with Bootstrap styles):

<p><input id="subject" type="text" placeholder="type your subject here" 
    class="form-control"></p>
<p><input id="message" type="text" placeholder="type your message here" 
    class="form-control"></p>
<p><a id="mail-link" class="btn btn-primary">Create email</a></p>

JavaScript (with jQuery ):

<script type="text/javascript">
    function loadEvents() {
        var mailString;
        function updateMailString() {
            mailString = '?subject=' + encodeURIComponent($('#subject').val())
                + '&body=' + encodeURIComponent($('#message').val());
            $('#mail-link').attr('href',  'mailto:person@email.com' + mailString);
        }
        $( "#subject" ).focusout(function() { updateMailString(); });
        $( "#message" ).focusout(function() { updateMailString(); });
        updateMailString();
    }
</script>

Notes:

• The <form> element with associated action attribute is not used.
• The <input> element of type button is also not used.
  • <a> styled as a button (here using Bootstrap) replaces <input type="button">
  • focusout() with updateMailString() is necessary because the <a> tag's href attribute does not automatically update when the input fields' values change.
  • updateMailString() is also called when document is loaded in case the input fields are prepopulated.
• Also encodeURIComponent() is used to get characters such as the quotation mark (") across to Outlook.

In this approach, the mailto: URI is supplied (with subject and body attributes) in an a element's href tag. This works in all combinations of browsers and e-mail clients I have tested, which are recent (2015) versions of:

• Browsers: Firefox/Win&OSX, Chrome/Win&OSX, IE/Win, Safari/OSX&iOS, Opera/OSX
• E-mail clients: Outlook/Win, Mail.app/OSX&iOS, Sparrow/OSX

Bonus tip: In my use cases, I add some contextual text to the e-mail body . More often than not, I want that text to contain line breaks. %0D%0A (carriage return and linefeed) works in my tests.

I couldn't ever find an answer that really satisfied the original question, so I put together a simple free service ( PostMail ) that allows you to make a standard HTTP POST request to send an email. When you sign up, it provides you with code that you can copy & paste into your website. In this case, you can simply use a form post:

HTML:

<form action="https://postmail.invotes.com/send"
    method="post" id="email_form">

    <input type="text" name="subject" placeholder="Subject" />
    <textarea name="text" placeholder="Message"></textarea>
    <!-- replace value with your access token -->
    <input type="hidden" name="access_token" value="{your access token}" />

    <input type="hidden" name="success_url"
      value=".?message=Email+Successfully+Sent%21&isError=0" />
    <input type="hidden" name="error_url"
      value=".?message=Email+could+not+be+sent.&isError=1" />

    <input id="submit_form" type="submit" value="Send" />
</form>

Again, in full disclosure, I created this service because I could not find a suitable answer.

Even though it is very old and irrelevant now, I am replying to help people like me! it should be like this:

<form method="post" action="mailto:$emailID?subject=$MySubject &message= $MyMessageText">

Here $emailID, $MySubject, $MyMessageText are variables which you assign from a FORM or a DATABASE Table or just you can assign values in your code itself. Alternatively you can put the code like this (normally it is not used):

<form method="post" action="mailto:admin@website.com?subject=New Registration Alert &message= New Registration requires your approval">

Answer 6

You can use an anchor to attempt to open the user's default mail client, prepopulated, with mailto: , but you cannot send the actual email. *Apparently it is possible to do this with a form action as well, but browser support is varied and unreliable, so I do not suggest it.

HTML cannot send mail, you need to use a server side language like php, which is another topic. There are plently of good resources on how to do this here on SO or elsewhere on the internet.

If you are using php, I see SwiftMailer suggested quite a bit.

Answer 7

You can not directly send an email with a HTML form. You can however send the form to your web server and then generate the email with a server side program written in eg PHP.

The other solution is to create a link as you did with the "mailto:". This will open the local email program from the user. And he/she can then send the pre-populated email.

When you decided how you wanted to do it you can ask another (more specific) question on this site. (Or you can search for a solution somewhere on the internet.)
