1.使用document.form.action方式

相關源碼如下：

*.js

[javascript]

復制代碼 代碼如下:

<span> </span> document.getElementById("sendPerson").value = SendPerson;
document.getElementById("currentTime").value = currentTime();
document.getElementById("message").value = message;
document.getElementById("recvPerson").value = recvPerson;
document.chatform.action = "ToHistoryServlet";
document.chatform.submit();
*.html

復制代碼 代碼如下:

<!--the tag below is the params to the userHistory dml@2012.8.27-->
<input type="hidden"> <input
type="hidden"> <input
type="hidden"> <input
type="hidden">

[java]

復制代碼 代碼如下:

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

String sendPerson = request.getParameter("sendPerson");
String recvPerson = request.getParameter("recvPerson");
String sendTime = request.getParameter("currentTime");
String message = request.getParameter("message");
Message msg = new Message();
msg.setMessage(message);
msg.setRecvPerson(recvPerson);
msg.setSendPerson(sendPerson);
msg.setSendTime(sendTime);
HistoryHandle.addMessage(msg);
}

2.jquery調用后臺方法

[javascript]

復制代碼 代碼如下:

$.ajax({
type : "POST",
contentType : "application/json",
url : "ToHistoryServlet?sendPerson=" + SendPerson + "¤tTime="
+ currentTime() + "&message=" + message + "&recvPerson="
+ recvPerson,
dataType : 'json',
success : function(result) {
alert(result.d);
}
});
