【问题描述】:
我将Angular UI's typeahead 与Web Api 结合使用来加载搜索结果。 我的 Angular 是 1.2.2 版,引导程序是 3.1.0。我应该提到我也在使用打字稿。
当我在搜索框中输入内容时,我希望带有建议的下拉菜单会从输入中掉下来。当我检查控制台时,我看到了我返回的数据,问题是没有出现下拉菜单来显示它。
这是我的 HTML + angular 指令:
<div class="input-group">
<input type="text" class="form-control" placeholder="Search" ng-model="selected"
data-typeahead="searchResult as searchResult for searchResult in search($viewValue) | filter:$viewValue" >
<div class="input-group-btn">
<button class="btn btn-default" type="submit" ng-click="search(Text)"><i class=" glyphicon glyphicon-search"></i></button>
</div>
</div>
这是位于我的控制器中的 js 函数:
$scope.search = function (criteria) {
controller.dataService.search($scope.employeeId, criteria, function (data) {
$scope.searchResult = data;
});
这是我的数据服务中的搜索功能。
export interface ICommonDataService extends IBaseDataService {
search(employeeId: string, criteria: string, successCallback: (data: SearchResult) => any);
}
dataservice.ts 信息:
export class DataServicBase {
public httpService: ng.IHttpService;
public serviceBase = '/services/api';
public static $inject = [
'$http'
];
constructor($http: any) {
this.httpService = $http;
}
}
export class CommonDataService extends DataServicBase implements ICommonDataService {
public serviceUrl = this.serviceBase + '/common';
search(employeeId: string, criteria: string, successCallback: (data: SearchResult) => any) {
this.httpService.get(this.serviceUrl + '/' + employeeId + '/search/' + criteria)
.success(function (data) {
successCallback(data);
});
}
}
这就是 SearchResult 的样子:
// Class
export class SearchResult {
// Constructor
constructor(
public Employees: Employee[],
public Filters: Employee[],
public Projects: Project[]
) {
}
}
我得到的错误是:

【问题讨论】:
-
向我们展示您的 JavaScript 代码(服务)。但是快速查看您的示例,您似乎没有从您的
search方法返回任何内容。 -
@pkozlowski.opensource 我已经更新了这个问题。如果您需要更多信息,请告诉我,以防我错过了上面的内容。
-
我们需要查看
controller.dataService中的代码——JavaScript 中的dataService是什么,它是如何编写的? -
@pkozlowski.opensource 我已包含数据服务信息。
