我的HTML代码是:
<p>
<input type="text" ng-model="destination" placeholder="Destination"
uib-typeahead="dest as dest.name for dest in getDestinations($viewValue)" typeahead-loading="loadingDestinations"
typeahead-no-results="noResults" typeahead-min-length="3">
<i ng-show="loadingDestinations">...</i>
<div ng-show="noResults">
<i>xxx - </i> No Destinations Found
</div>
</p>
我的getDestinations()函数,它返回一个HttpPromise:
$scope.getDestinations = function(viewValue) {
console.log(viewValue);
return $http.get('/api/destAutoComplete', {
params : {
prefix: viewValue,
countryId: 94
}
});
}
返回输入的响应&#34; ist&#34;来自服务器:
[
{
"name": "Costa del Sol / Istan",
"cityId": 5452,
"locationId": 30083
},
{
"name": "Istanbul",
"cityId": 1122,
"locationId": null
}
]
正如您所见,服务器将正确过滤的结果作为json数组返回,但是typeahead从不显示结果,并始终显示&#34; No Destinations Found&#34;。我究竟做错了什么?我想表明&#34; name&#34;作为typeahead下拉列表中的标签,并在选择一个时将整个dest对象设置为作用域中的目标。

这是因为您忘记返回您的承诺对象。根据Angular Bootsrap UI code comment,
任何返回promise对象的函数都可以用来异步加载值。
试试这个
$scope.getDestinations = function(viewValue) {
console.log(viewValue);
return $http.get('/api/destAutoComplete', {
params: {
prefix: viewValue,
countryId: 94
}
}).then(function(response) {
// or whatever response you are getting
return response.data.results;
});;
}
