<body>
<div id="divCustomers">hello</div>

alert(result.name);//测试对象和数组..
for(i in arr){
alert(arr[i]);
}
}
</script>
<script type="text/javascript" src="http://localhost:8080/SendJsonP/servlet/responseJson?callBack=onCustomerLoaded"></script>

请求另外域名中的一个servlet。。
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String funName=request.getParameter("callBack");//得到需要调用的函数名
PrintWriter out = response.getWriter();
out.write(funName+"({name:'sking7'},['a','b'])");//返回参数对象，和数组
out.flush();
out.close();
}
