Question

我在这里追我的尾巴。我要做的就是从$ scope.getPlacesTextRaw函数返回一个字符串。

$scope.getPlacesTextRaw = function(selectedPlace){

    mentionsFactory.getPlaceMetaData(selectedPlace).then(function(metadata) {
        console.log("here is our metadata", metadata);
        return metadata.description.replace(/ /g,"_");
    });

};

另一次尝试：

$scope.getPlacesTextRaw = function(selectedPlace){
    var deferred = $q.defer();

    mentionsFactory.getPlaceMetaData(selectedPlace).then(function(metadata) {
        console.log("here is our metadata", metadata);
        deferred.resolve('@' + metadata.description.replace(/ /g,"_"));
    });

    deferred.promise.then(function(string){
        return string;
    });
};

我在指令中调用getPlacesTextRaw：

<mentio-menu
    mentio-for="'hashtag'"
    mentio-trigger-char="'@'"
    mentio-items="places"
    mentio-template-url="/places-mentions.tpl"
    mentio-search="searchPlaces(term)"
    mentio-select="getPlacesTextRaw(item);">
</mentio-menu>

所以我想:) 请看这里https://docs.angularjs.org/error/$rootScope/infdig?p0=10&p1=%5B%5D第二块

你有一点改变方法，请看看演示：http://jsbin.com/kakim/2/edit

不过mentio-select="getPlacesTextRaw(item)做mentio-select="PlacesTextRaw"

 $scope.PlacesTextRaw = "";

    $scope.getPlacesTextRaw = function (selectedPlace) {
        mentionsFactory.getPlaceMetaData(selectedPlace).then(function (metadata) {
            console.log("here is our metadata", metadata);
            $scope.PlacesTextRaw = metadata.description.replace(/ /g, "_");



        });

    };

    $scope.item = "test"

    function activate() {

        $scope.getPlacesTextRaw($scope.item);
    }
    activate();
