   // 业务方法  
   editFunc() {  
                uni.showLoading({  
                    title: '处理中...'

        if (res.updated === 1) {  
            let result = Object.assign({}, {  
                _id: event.data.id  
            }, event)  
            return {  
                status: 0,  
                msg: `集合数据由${JSON.stringify(docList.data[0])}修改为${JSON.stringify(result)}`
