双向数据绑定不适用于控制器 - AngularJS

Question

早上好，S.O.大师。我很难让双向数据绑定工作。两种方式的数据绑定在每个其他控制器中都可以正常工作，但这让我很难过。可以帮忙吗？

控制器/HTML：

app.controller('search', function($scope, $http, $location) {
$scope.searchText = "";
	$scope.searchRun = function() {
		
		
		$scope.userQuery = "Last::Name+eq+"+$scope.searchText.replace(/ /g,"::")+"+or+First::Name+eq+"+$scope.searchText.replace(/ /g,"::")+"+or+Display::Name+eq+"+$scope.searchText.replace(/ /g,"::")+"+or+User::Login+eq+"+$scope.searchText.replace(/ /g,"::")+"+or+Manager::Display::Name+eq+"+$scope.searchText.replace(/ /g,"::");
		
		$http({
        		method: 'GET',
       		url: url
    		})
    		.then(function(res) {
			
			$scope.TransmutedUsers = {
				users: [
			
				]
			};
			//Looping through users making a new object
			for(var i = 0; i < res.data.users.length; i++) {
				//console.log(res.data.users[i].id);
				var obj = {
					id: res.data.users[i].id
				};

				for(var x = 0; x < res.data.users[i].fields.length; x++) {
					//console.log(res.data.users[i].fields[x].name);
					var nameVar = res.data.users[i].fields[x].name.replace(/\s+/g, '');
					var valueVar = res.data.users[i].fields[x].value;
			
					obj[nameVar] = valueVar;		
			
				}
					$scope.TransmutedUsers.users.push(obj);
			}

		
			console.log($scope.TransmutedUsers.users);
			$scope.returnedUsersLength = $scope.TransmutedUsers.users.length;
			console.log($scope.returnedUsersLength);
			sessionStorage.setItem("searchActive", "true");
			
			
			if ($location.url() != "/search") {
				$location.url("/search");
			}
			
    		});
	};
});

            </div>
            <div class="row" ng-repeat="user in TransmutedUsers.users">
                <div class="col-sm-12">

		  </div>
            </div>
        </div>
    </div>
</div>

searchText 会执行 console.log，但它没有绑定到 {{searchText}}，并且 url 确实以指定的格式成功返回了对象，但这也不适用于 {{}}。

使用 AngularJS 1.6

如果需要其他信息来帮助我解决这个难题，请告诉我。谢谢大家！

Answer 1

在搜索函数外声明$scope.searchText后，

你可以通过替换表格来强制它：

<form ng-controller="search" ng-submit="searchRun();" class="pull-right">
                    <input type="text" placeholder="Search for people or requests" ng-model="searchText">
                    <button type="submit"><i class="fa fa-search"></i></button>
                </form>

用一些简单的东西，比如：

<input type="text" placeholder="Search for people or requests" ng-model="searchText">
 <button ng-click="searchRun(searchText)"><i class="fa fa-search"></i></button>

在您的搜索功能中：

$scope.searchRun = function(searchText) {
        $scope.searchText = searchText;
        ...rest of ur code

---

您也可以尝试使用它来调试它，以便直接在 html 中查看输入中所做的更改。

<input type="text" ng-model="searchText">
{{searchText}}

并在你的控制器中声明函数之外

$scope.searchText = "";

Answer 2

所以问题在于您使用了两个 ngController。

From Angularjs Docs

当控制器通过 ng-controller 指令附加到 DOM 时，AngularJS 将使用指定控制器的构造函数实例化一个新的控制器对象。将创建一个新的子作用域，并作为 $scope 的控制器构造函数的可注入参数提供。

所以尝试通过 ng-controller 在你的 DOM 结构上声明一个 "search" 控制器，以便 Div 共享这个控制器实例。与 angularjs 不同，服务控制器不是单例。

我为您创建了一个 plunker 来显示问题：http://plnkr.co/edit/J2Ho1uLq0jzuVLlX3BLG

改变一个控制器的作用域不会改变另一个控制器的作用域
