Question

我有一个＆＃34;搜索＆＃34;用户输入一个值，我想在服务中发送此值，因为我希望另一个控制器可以访问。但是目前我不能这样做，如果有人可以帮助我，那么使用Angular js将是非常有用的。

和js

＆＃13;

var app = angular.module('MainApp', [])

app.factory('Search', function($rootScope, $http){
var search = '';
	function setSearch(bus){
		search = bus;
	}
	function getSearch(){
		return search;
	}
	return{
		setSearch : setSearch,
		getSearch: getSearch

	};
	//return myFactory;
	/*
	$scope.Search = function() {
		return {
			getDoctor: function () {
				return $http.get('api/doctor' + $scope.search.searchText).then(function (response) {
					orders = response.data;
					$rootScope.$broadcast('handleSharedOrders', orders);
					return orders;
				})
			}
		};
	}*/
});

app.controller('mainController', function ($scope, $http, Search) {


	$scope.loadList = function() {
		location.href = "doctors";
	};

$scope.search.searchText = Search.getSearch();
	$scope.Search = function(bus) {
		console.log(bus);
		Search.setSearch(bus);


	}


	$scope.doctors = {};
	$http.get('/api/doctor').success(function (data) {
		$scope.doctors = data;
	})
		.error(function (data) {
			console.log('Error: ' + data);
		});


	/*
	$http.get('/api/doctor/' + specialty).success(function (data) {
		$scope.doctorsSpecialty = data;
	})
		.error(function (data) {
			console.log('Error: ' + data);
		});
*/


});

谢谢你的帮助

Answer 1

您已定义search.searchText：

<input ng-model="search.searchText" type="text" class="form-control" placeholder="Search..." align="center">

在这里你试图只传递searchText（未定义）：

<button class="btn btn-default" type="button" align="center" ng-click="Search(searchText)">
    <b align="center">Search</b>
</button>

您需要更改ng-model上的<input>以进行搜索＆＃39;或者将ng-click上的<button>更改为＆＃39;搜索（search.searchText）＆＃39;。如果您选择执行后者，您可能还需要在控制器中显式创建search对象。

Answer 2

我认为你做得很好，但你的代码有一些错误。首先，您不是在范围内声明对象搜索，而是将属性searchText分配给它。所以你应该这样做：

$scope.search = {
        searchText: ''
    };

然后，在单击搜索的视图中，您传递的是searchText，但它应该是search.searchText。
