我希望我的网站有能力发送电子邮件而不刷新页面。我想用Javascript。

<form action="javascript:sendMail();" name="pmForm" id="pmForm" method="post">
Enter Friend's Email:
<input name="pmSubject" id="pmSubject" type="text" maxlength="64" style="width:98%;" />
<input name="pmSubmit" type="submit" value="Invite" />

这是我想调用的函数,但我不确定把什么放入javascript函数。从我所做的研究中,我发现了一个使用mailto方法的示例,但我的理解是,它实际上并不直接从站点发送。

所以我的问题是,我可以在哪里找到什么放入JavaScript函数直接从网站发送电子邮件。

function sendMail() {
    /* ...code here...    */
}

当前回答

有一种组合服务。您可以将上面列出的解决方案(如mandrill)与EmailJS服务结合使用,这可以使系统更加安全。 不过他们还没有开始服务。

其他回答

我找不到一个能真正满足最初问题的答案。

Mandrill是不可取的,因为它是新的定价政策,加上它需要一个后端服务,如果你想保持你的凭证安全。 最好隐藏你的电子邮件,这样你就不会出现在任何列表中(mailto解决方案暴露了这个问题,对大多数用户来说不方便)。 仅仅为了发送一封电子邮件而设置sendMail或需要一个后端是很麻烦的。

我提供了一个简单的免费服务,允许您发出标准的HTTP POST请求来发送电子邮件。它叫做PostMail,你可以使用JavaScript或jQuery简单地发布一个表单。当你注册时,它为你提供代码,你可以复制和粘贴到你的网站。下面是一些例子:

JavaScript:

<form id="javascript_form">
    <input type="text" name="subject" placeholder="Subject" />
    <textarea name="text" placeholder="Message"></textarea>
    <input type="submit" id="js_send" value="Send" />
</form>

<script>

    //update this with your js_form selector
    var form_id_js = "javascript_form";

    var data_js = {
        "access_token": "{your access token}" // sent after you sign up
    };

    function js_onSuccess() {
        // remove this to avoid redirect
        window.location = window.location.pathname + "?message=Email+Successfully+Sent%21&isError=0";
    }

    function js_onError(error) {
        // remove this to avoid redirect
        window.location = window.location.pathname + "?message=Email+could+not+be+sent.&isError=1";
    }

    var sendButton = document.getElementById("js_send");

    function js_send() {
        sendButton.value='Sending…';
        sendButton.disabled=true;
        var request = new XMLHttpRequest();
        request.onreadystatechange = function() {
            if (request.readyState == 4 && request.status == 200) {
                js_onSuccess();
            } else
            if(request.readyState == 4) {
                js_onError(request.response);
            }
        };

        var subject = document.querySelector("#" + form_id_js + " [name='subject']").value;
        var message = document.querySelector("#" + form_id_js + " [name='text']").value;
        data_js['subject'] = subject;
        data_js['text'] = message;
        var params = toParams(data_js);

        request.open("POST", "https://postmail.invotes.com/send", true);
        request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");

        request.send(params);

        return false;
    }

    sendButton.onclick = js_send;

    function toParams(data_js) {
        var form_data = [];
        for ( var key in data_js ) {
            form_data.push(encodeURIComponent(key) + "=" + encodeURIComponent(data_js[key]));
        }

        return form_data.join("&");
    }

    var js_form = document.getElementById(form_id_js);
    js_form.addEventListener("submit", function (e) {
        e.preventDefault();
    });
</script>

jQuery:

<form id="jquery_form">
    <input type="text" name="subject" placeholder="Subject" />
    <textarea name="text" placeholder="Message" ></textarea>
    <input type="submit" name="send" value="Send" />
</form>

<script>

    //update this with your $form selector
    var form_id = "jquery_form";

    var data = {
        "access_token": "{your access token}" // sent after you sign up
    };

    function onSuccess() {
        // remove this to avoid redirect
        window.location = window.location.pathname + "?message=Email+Successfully+Sent%21&isError=0";
    }

    function onError(error) {
        // remove this to avoid redirect
        window.location = window.location.pathname + "?message=Email+could+not+be+sent.&isError=1";
    }

    var sendButton = $("#" + form_id + " [name='send']");

    function send() {
        sendButton.val('Sending…');
        sendButton.prop('disabled',true);

        var subject = $("#" + form_id + " [name='subject']").val();
        var message = $("#" + form_id + " [name='text']").val();
        data['subject'] = subject;
        data['text'] = message;

        $.post('https://postmail.invotes.com/send',
            data,
            onSuccess
        ).fail(onError);

        return false;
    }

    sendButton.on('click', send);

    var $form = $("#" + form_id);
    $form.submit(function( event ) {
        event.preventDefault();
    });
</script>

再次坦白地说,我创建这个服务是因为我找不到合适的答案。

你可以在这篇文章中找到在JavaScript函数中放入的内容。

function getAjax() {
    try {
        if (window.XMLHttpRequest) {
            return new XMLHttpRequest();
        } else if (window.ActiveXObject) {
            try {
                return new ActiveXObject('Msxml2.XMLHTTP');
            } catch (try_again) {
                return new ActiveXObject('Microsoft.XMLHTTP');
            }
        }
    } catch (fail) {
        return null;
    }
}

function sendMail(to, subject) {
     var rq = getAjax();

     if (rq) {
         // Success; attempt to use an Ajax request to a PHP script to send the e-mail
         try {
             rq.open('GET', 'sendmail.php?to=' + encodeURIComponent(to) + '&subject=' + encodeURIComponent(subject) + '&d=' + new Date().getTime().toString(), true);

             rq.onreadystatechange = function () {
                 if (this.readyState === 4) {
                     if (this.status >= 400) {
                         // The request failed; fall back to e-mail client
                         window.open('mailto:' + to + '?subject=' + encodeURIComponent(subject));
                     }
                 }
             };

             rq.send(null);
         } catch (fail) {
             // Failed to open the request; fall back to e-mail client
             window.open('mailto:' + to + '?subject=' + encodeURIComponent(subject));
         }
     } else {
         // Failed to create the request; fall back to e-mail client
         window.open('mailto:' + to + '?subject=' + encodeURIComponent(subject));
     }
}

提供您自己的PHP(或任何语言)脚本来发送电子邮件。

Javascript是客户端,你不能用Javascript发邮件。浏览器可能只识别mailto:,并启动默认的邮件客户端。

完整的反垃圾邮件版本:

<div class="at">info<i class="fa fa-at"></i>google.com</div>
OR
<div class="at">info&#x40;google.com</div>


<style>
.at {
  color: blue;
  cursor: pointer;
}
.at:hover {
  color: red;
}
</style>

<script>
const el33 = document.querySelector(".at");
el33.onclick = () => {
  let recipient="info";
  let at = String.fromCharCode(64);
  let dotcom="google.com";
  let mail="mailto:";
  window.open(mail+recipient+at+dotcom);
}
</script>

另一种从JavaScript发送电子邮件的方法是使用directtomx.com,如下所示;

 Email = {
 Send : function (to,from,subject,body,apikey)
    {
        if (apikey == undefined)
        {
            apikey = Email.apikey;
        }
        var nocache= Math.floor((Math.random() * 1000000) + 1);
        var strUrl = "http://directtomx.azurewebsites.net/mx.asmx/Send?";
        strUrl += "apikey=" + apikey;
        strUrl += "&from=" + from;
        strUrl += "&to=" + to;
        strUrl += "&subject=" + encodeURIComponent(subject);
        strUrl += "&body=" + encodeURIComponent(body);
        strUrl += "&cachebuster=" + nocache;
        Email.addScript(strUrl);
    },
    apikey : "",
    addScript : function(src){
            var s = document.createElement( 'link' );
            s.setAttribute( 'rel', 'stylesheet' );
            s.setAttribute( 'type', 'text/xml' );
            s.setAttribute( 'href', src);
            document.body.appendChild( s );
    }
};

然后从页面中调用它,如下所示;

 window.onload = function(){
    Email.apikey = "-- Your api key ---";
    Email.Send("to@domain.com","from@domain.com","Sent","Worked!");
 }
