我需要用 jsp 发送邮件,但页面本身不能重新加载。重新加载 POST 事件时,整个实现工作正常,但调整代码以使用 ajax 会破坏它。当触发ajax事件时,似乎没有执行index.jsp中的jsp-Code。我将展示一些片段:
索引.jsp
<%
String result = "=(";
String to = request.getParameter("rec_mail");
if(to != null) {
String from = request.getParameter("sendermail");
String host = "mailserver";
Properties properties = System.getProperties();
properties.setProperty("mail.smtp.host", host);
Session mailSession = Session.getDefaultInstance(properties);
try{
MimeMessage message = new MimeMessage(mailSession);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to));
message.setSubject("Feedback");
message.setText(request.getParameter("feedbackinput"));
Transport.send(message);
result = "Sucess!";
}catch (MessagingException e) {
e.printStackTrace();
result = "failed!";
}
}
out.println(request.getParameter("sendermail"));
out.println(result);
%>
<input id="bsend" class="fbutton" type="submit" name="send" value="Send" onclick="loadContent()" style="float:right; width:18%; height:35%;" >
ajax.js
var xmlhttp
function loadContent() {
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null)
{
alert ("Your browser does not support Ajax!");
return;
}
var url="./index.jsp";
xmlhttp.open("post",url,true);
xmlhttp.send(null);
xmlhttp.onreadystatechange=getOutput;
}
function getOutput()
{
if (xmlhttp.readyState==4)
{
alert("Message sent!");
}
}
function GetXmlHttpObject()
{
if (window.XMLHttpRequest)
{
return new XMLHttpRequest();
}
if (window.ActiveXObject)
{
return new ActiveXObject("Microsoft.XMLHTTP");
}
return null;
}
(只显示相关部分,无处不在)
我收到警报消息,但没有发送邮件......我希望很清楚,我正在尝试做什么......
谢谢!
此致
