javaScript Beginner：将数据从java-script发送到servlet？

Question

我正在JavaScript中创建动态表单。我想从JavaScript发送数据到servlet。我不使用任何提交按钮在我的Form.Using按钮，我只想发送数据。任何人都可以帮助我。

这是我的代码：

var myform=document.createElement("form"); 
myform.setAttribute("id", "myform"); 

var tname=document.createElement('input'); 
tname.setAttribute('type','text'); 
tname.setAttribute('name', "name"); 

var leaveMessage=document.createElement('input'); 
leaveMessage.setAttribute('type','button'); 
leaveMessage.setAttribute('name', "msgButton"); 
leaveMessage.setAttribute('value', "Leave Message"); 

myform.appendChild(tname); 
myform.appendChild(leaveMessage); 

document.body.appendChild(myform); 

Answer 1

添加一些语句也

var myform=document.createElement("form"); 
myform.setAttribute("id", "myform"); 
myform.setAttribute('action', "/mypage"); 
myform.setAttribute('method', "post"); 

var tname=document.createElement('input'); 
tname.setAttribute('type','text'); 
tname.setAttribute('name', "name"); 
var leaveMessage=document.createElement('input'); 
leaveMessage.setAttribute('type','button'); 
leaveMessage.setAttribute('name', "msgButton"); 
leaveMessage.setAttribute('value', "Leave Message"); 

myform.appendChild(tname); 
myform.appendChild(leaveMessage); 

document.body.appendChild(myform); 

document.forms["myform"].submit();
