我在使用Bootstrap-UI的typeahead控件和動態數據(從ajax調用中獲取數據)時遇到問題。在AngularJS應用中使用typeahead和ajax
在我服務的響應看起來有點像這樣[{id:1, text:'somebrand'},{id:2, text:'something'}]
的HTML看起來像這樣:
<input type="text" ng-model="result" min-length="2" typeahead="brand.id as brand.text for brand in brands($viewValue)" style="display:block">
在我控制我找回這樣的內容:
$scope.brands = function(brandName){
$http.post('/brands/getbrandsviewmodel', { query : brandName}).then(function(response){
return limitToFilter(response.data, 15);
});
};
我遇到的問題是Bootstrap-UI中的錯誤,如下所示:
Cannot read property 'length' of undefined
at http://localhost:3000/assets/ui-bootstrap-tpls-0.4.0.js?body=1:2749:24
當我調試到引導的UI代碼,我看到錯誤這裏occures,這是未定義匹配:
//it might happen that several async queries were in progress if a user were typing fast
//but we are interested only in responses that correspond to the current view value
if (inputValue === modelCtrl.$viewValue) {
if (matches.length > 0) {....
我最初的反應是,引導-UI的預輸入不知道當數據被檢索到,但我不知道爲什麼,因爲我使用的是承諾?
它做了一個世界的區別,謝謝:) – Dofs
感謝的人,它可以幫助我! –
