原逻辑:

保存=>验证

新需求:

保存=>验证=>验证2（异步1=>异步2=>异步3=>验证结果）

新逻辑:

验证=>前验证=>验证2-异步1=>验证2-异步2=>验证2-异步3=>后验证=>保存

新逻辑实现:

验证

$scope.checkDoctorOrders = function () {$scope.R1007isPassed = 0;//默认未通过var p = new Promise((resolve,reject)=>{ resolve()})p.then($scope.checkDoctorOrdersPre)	}

前验证

$scope.checkDoctorOrdersPre = function(){...$scope.CheckisPassed =  true;var p = Promise.resolve().then($scope.platformConfirm_R1007_sub1)console.log("checkDoctorOrdersPre done");return p;}

验证2-异步1

$scope.platformConfirm_R1007_sub1 = function(){var registerId = $scope.curPatient.RegisterId;var subUrl = "Register/GetRegisterRecord";var regData = { RegisterId: registerId }Http.requestData({ url: subUrl, data: regData }, function (data) {			var p = Promise.resolve(data).then($scope.platformConfirm_R1007_sub2)console.log("platformConfirm_R1007_sub1 done")return p;}, function (data) { });}

验证2-异步2

$scope.platformConfirm_R1007_sub2 = function(data){...var subData = {sysCode: "R1007",method: "DuplicateItemVerify",UserInfo: "访问接口账号",data: sendData,};				var jsbody =  JSON.stringify(subData)var appendurl = "?strJson="+jsbodyHttp.requestData({url: subUrl+appendurl}, function (repdata) {console.log(repdata.respCode);                    }, function (repdata) { var p = Promise.resolve(repdata).then($scope.platformConfirm_R1007_sub3)console.log("platformConfirm_R1007_sub2 done")return p;});}}

验证2-异步3

$scope.platformConfirm_R1007_sub3 = function(repdata){if (repdata.respCode == "10000") {			if (repdata.respData.IsRepeat == 1) {                            var popUrl = repdata.respData.PromptUrl;console.log(popUrl);window.open(popUrl);}else{$scope.R1007isPassed = 1;//设置通过console.log($scope.R1007isPassed);		var p = Promise.resolve().then($scope.checkDoctorOrdersAfter)				console.log("platformConfirm_R1007_sub3 done")return p;}}}

后验证

$scope.checkDoctorOrdersAfter = function(){	if ($scope.R1007isPassed == 0) {$scope.CheckisPassed =  false;}console.log("checkDoctorOrdersAfter done");if ($scope.CheckisPassed ==true){//调用保存方法$scope.saveDoctorItem();}}

保存

$scope.saveDoctorItem = function () {//if (!$scope.checkDoctorOrders()) return false;...$scope.saveInPatientOrder();}

总结:

关键还是思路的转变,之前是验证由保存触发,调整为将保存作为链式调用的最后一个节点
