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... */
}
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。
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!");
}
