Question

我正在尝试使用ajax从一个页面传递2个输入值，如果它成功，那么它会提醒其他错误它会提醒错误。当我在谷歌浏览器或mozilla中运行时firefox，我没有在console中得到任何错误。所以我认为没有错误但是警报没有来。也没有警告错误。这是html部分的jsffidle 以下行在head标签的html页面中

<meta http-equiv="Content-Type" content="text/html; charset=US-ASCII">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link href="http://getbootstrap.com/2.3.2/assets/css/bootstrap.css" rel="stylesheet">
<link href="http://getbootstrap.com/2.3.2/assets/css/bootstrap-responsive.css" rel="stylesheet">
<script type="text/javascript" src="https://code.jquery.com/jquery.min.js"></script>
<script type="text/javascript" src="http://getbootstrap.com/2.3.2/assets/js/bootstrap.js"></script>

http://jsfiddle.net/P6vhG/

这是jsp代码

<%!String number,message; %>
<%
number=request.getParameter("toNumber");
message=request.getParameter("body");
out.println(number+"    "+message);




%>

请为此提供解决方案。

这是完整的JSP代码

这是完整的messageSending.jsp代码

    pageEncoding="UTF-8"%>

<%!String number,message; %>
<%
number=request.getParameter("toNumber");
message=request.getParameter("body");
out.println(number+"    "+message);



%>

Answer 1

问题在于您的javascript，逗号丢失，之后 - ＆gt; data: { toNumber: number, body: msg}

将逗号放在那边后工作正常。
