這已被詢問並回答了很多次。 但是,嘗試了很多東西之後,我仍然有這個問題。
我在Angular中有一個搜索按鈕的單頁面。參數越來越低谷,並像這樣登錄console.log("searched: " + search.term);
然後我使用這個術語來查詢我的數據庫使用REST,結果回來很好。都好!
現在,我想用這些新結果更新$ scope數據。我很努力地通過添加$scope.$apply()
並使用$timeout
和使用$digest
。
這一切都使我的錯誤:$消化正在進行中
然後我用$範圍$手錶,這樣的作品,我使用警報測試,但數據永遠不會改變我的瀏覽器。
'use strict';
// Declare app level module which depends on views, and components
angular.module('Grep GUI', [
'ngRoute',
'myApp.view1',
'myApp.view2',
'myApp.version'
]).
config(['$locationProvider', '$routeProvider', function($locationProvider, $routeProvider) {
$locationProvider.hashPrefix('!');
$routeProvider.otherwise({redirectTo: '/view1'});
}]).
controller('DataBeest', function($scope, $http) {
$http.get('http://localhost:8529/_db/grep/grepdata/huizen').
then(function(response) {
$scope.greeting = response.data;
});
$scope.search = function(search) {
console.log("searched: " + search.term);
$http.get('http://localhost:8529/_db/grep/zoek/zoek/' + search.term).
then(function(response) {
$scope.greeting = response.data;
$scope.$digest()
});
}
});

您使用的是原生使用'$ http'服務的角度AJAX,那麼爲什麼你需要'$ scope。$ digest()'? –
我認爲你可以刪除$ scope。$ digest(),你應該可以看到在 – CrazyMac
'$ scope。$ apply'或'$ scope。$ digest'下的修改後的值在這裏不需要。如果您在沒有角度知識的情況下更新數據,您只需要這些。看起來你的問題更多的是在你的搜索中的迴應;你有沒有登錄它來驗證它有你期望的數據? – Claies
