ajax调用实例

海尔订阅按钮的例子：

    $(".dingyue").click(function () {
        if (istrsidssdssotoken()) {//cookie 中的是否登录
            if (null == proid || "undefined" == proid) {

                        }
                        //监控代码
                        collection_success();
                    } else {
                        gotoLogin();
                    }
                },
                error: function () {
                }
            });


        } else {
            gotoLogin();
        }
    })

最简单的例子：

 $.ajax({
        url:"/api/workflow/task!cancelAndAgreeOrDisagreeStep.do",
        dataType: 'json',
        type: 'post',
        data: {
            task_id: task_id
        },
        success: function success(data) {
            //成功后执行的动作
             
        },
        error: function error() {
            //alert('获取信息失败');
        }
    });
