使用AngularJS和php TypeError的自动完成搜索无法读取属性'；搜索文本'；未定义的

我正在尝试进行自动完成搜索，因此我想从php文件中获取数据，但出现以下错误：

TypeError:无法读取未定义的属性“searchText”

我不知道是什么问题，我试了两天

这是我的密码：

clientToServer.js

function CltToServer($scope, $rootScope, $http) {
    $http({
        method: "get",
        url: "PureAngualr/SearchResultsQuery.php",
        dataType: 'json',
        data: {searchText: $rootScope.searchText},
        async: false,

        params: {
            action: "get"
        }
    }).success(function (data, status, headers, config) {
        $rootScope.suggestions = response.data;
        alert(2);

    }).error(function (data, status, headers, config) {
        // called asynchronously if an error occurs
        // or server returns response with an error status.
    });
}

app1.controller('autoCompleteCTRL', function ($scope, $rootScope, $http) {

    //Sort Array
    /*$rootScope.searchItems.sort();*/
    //Define Suggestions List
    $scope.searchText = '';
    $scope.selectedItem = undefined;
    $rootScope.suggestions = undefined;
    //Define Selected Suggestion Item
    $rootScope.selectedIndex = -1;


    //Function To Call On ng-change
    $rootScope.search = function ($scope, $rootScope, $http) {

        $rootScope.searchItems = CltToServer($scope, $rootScope, $http);

        alert(1);
        $rootScope.suggestions = CltToServer($scope, $rootScope, $http);
        var myMaxSuggestionListLength = 0;
        for (var i = 0; i < $rootScope.searchItems.length; i++) {
            var searchItemsSmallLetters = angular.lowercase($rootScope.searchItems[i]);
            var searchTextSmallLetters = angular.lowercase($scope.searchText);
            if (searchItemsSmallLetters.indexOf(searchTextSmallLetters) !== -1) {
                $rootScope.suggestions.push(searchItemsSmallLetters);
                myMaxSuggestionListLength += 1;
                if (myMaxSuggestionListLength == 5) {
                    break;
                }
            }
        }
    };

提前感谢：）

您的searchText是在$scope或$rootScope中定义的？可能是错误的，但

url:“PureAngualr/SearchResultsQuery.php”

在我看来像是一个打字错误。它不是

PureAngular

？PureAngular只是我放置php文件的一个字段。最后我发现问题，我必须向clientToServer.js添加控制器，因为我使用了两个单独的js文件。但是没有发生任何事情，建议列表没有出现！！你知道为什么吗？我的函数在au中有一些问题tocomplete.js？您的搜索文本是在$scope或$rootScope中定义的？可能是错误的，但
