因业务需求需要在主页面写自己的ajax请求，如：
function setNo(prefix, no){
$.ajax({
url: prefix + "/setNo",
data: {"no": no},
type: "post",
success: function(result) {
if (result.code == web_status.SUCCESS) {

                } else {
                    alert(result.msg);
                }
            }
        })
    }

prefix 为： host+"/case/details";
浏览器报错：
