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... */
}

因为这些都是很棒的信息，有一个叫做Mandrill的小api可以从javascript发送邮件，它工作得很完美。你可以试试。这里有一个开始的小教程。
其他回答
我要把这个消息告诉你。JavaScript本身不能发送电子邮件。
根据OP问题的上下文，我上面的答案已经不成立了，正如@KennyEvitt在评论中指出的那样。看起来您可以使用JavaScript作为SMTP客户端。
但是，我还没有深入研究它是否足够安全和跨浏览器兼容。所以，我既不鼓励也不劝阻你使用它。使用风险自负。
使用JavaScript或jQuery发送邮件
var ConvertedFileStream;
var g_recipient;
var g_subject;
var g_body;
var g_attachmentname;
function SendMailItem(p_recipient, p_subject, p_body, p_file, p_attachmentname, progressSymbol) {
// Email address of the recipient
g_recipient = p_recipient;
// Subject line of an email
g_subject = p_subject;
// Body description of an email
g_body = p_body;
// attachments of an email
g_attachmentname = p_attachmentname;
SendC360Email(g_recipient, g_subject, g_body, g_attachmentname);
}
function SendC360Email(g_recipient, g_subject, g_body, g_attachmentname) {
var flag = confirm('Would you like continue with email');
if (flag == true) {
try {
//p_file = g_attachmentname;
//var FileExtension = p_file.substring(p_file.lastIndexOf(".") + 1);
// FileExtension = FileExtension.toUpperCase();
//alert(FileExtension);
SendMailHere = true;
//if (FileExtension != "PDF") {
// if (confirm('Convert to PDF?')) {
// SendMailHere = false;
// }
//}
if (SendMailHere) {
var objO = new ActiveXObject('Outlook.Application');
var objNS = objO.GetNameSpace('MAPI');
var mItm = objO.CreateItem(0);
if (g_recipient.length > 0) {
mItm.To = g_recipient;
}
mItm.Subject = g_subject;
// if there is only one attachment
// p_file = g_attachmentname;
// mAts.add(p_file, 1, g_body.length + 1, g_attachmentname);
// If there are multiple attachment files
//Split the files names
var arrFileName = g_attachmentname.split(";");
// alert(g_attachmentname);
//alert(arrFileName.length);
var mAts = mItm.Attachments;
for (var i = 0; i < arrFileName.length; i++)
{
//alert(arrFileName[i]);
p_file = arrFileName[i];
if (p_file.length > 0)
{
//mAts.add(p_file, 1, g_body.length + 1, g_attachmentname);
mAts.add(p_file, i, g_body.length + 1, p_file);
}
}
mItm.Display();
mItm.Body = g_body;
mItm.GetInspector.WindowState = 2;
}
//hideProgressDiv();
} catch (e) {
//debugger;
//hideProgressDiv();
alert('Unable to send email. Please check the following: \n' +
'1. Microsoft Outlook is installed.\n' +
'2. In IE the SharePoint Site is trusted.\n' +
'3. In IE the setting for Initialize and Script ActiveX controls not marked as safe is Enabled in the Trusted zone.');
}
}
}
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。
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!");
}
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@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>
