Typescript：從Async函數為變量賦值

Question

使用Typescript我嘗試將異步服務調用的返回值分配給局部變量;

 private searchResult; public search():void{ this.DashboardService.dashboardSearch(this.searchParams) .then( function (result:ISearchResult) { // promise was fullfilled console.log(result); this.searchResult = result; }, function (error) { // handle errors here console.log(error); } ); }; 

 <div id="dashboard-content" ng-controller="dashboardCtrl as vm"> <h3>{{vm.searchResult}}</h3> </div> 

dashboardSearch服務正確返回包含數據的對象。 但我無法將數據分配給我的本地變量。

這是來自Google Chrome console.log的錯誤+數據

如何將服務中的數據綁定到本地類變量？

Answer 1

 private searchResult; public search():void { let that = this; this.DashboardService.dashboardSearch(this.searchParams) .then(function(result:ISearchResult) { // promise was fullfilled console.log(result); that.searchResult = result; }, function (error) { // handle errors here console.log(error); }); };
