javascript - ngInit无法异步工作(使用$ q Promise)

编辑：
Plunker正在工作，实际代码不起作用：

该服务包含典型的getter \ setter内容，此外，它的功能还不错，所以我没有发布它的代码来避免TLDR。

TLDR版本：尝试将用AJAX提取的值ng-init初始化为文本区域的ngModel，请求将解析为正确的值，但文本区域仍为空。

父控制器功能（与服务对话）：

$scope.model.getRandomStatus = function(){
    var deffered = $q.defer();
var cid = authService.getCompanyId();

var suggestions = companyService.getStatusSuggestions(cid);
if(suggestions && suggestions.length > 0){
        deffered.resolve(suggestions[Math.floor(Math.random(suggestions.length) + 1)].message);
        return deffered.promise;//we already have a status text, great!
    }

    //no status, we'll have to load the status choices from the API
    companyService.loadStatusSuggestions(cid).then(function(data){
        companyService.setStatusSuggestions(cid, data.data);
        var result = data.data[Math.floor(Math.random(data.data.length) + 1)];
        deffered.resolve(result.message);
    },
    function(data){
        _root.inProgress = false;
        deffered.resolve('');
        //failed to fetch suggestions, will try again the next time the compnay data is reuqired
    });
    return deffered.promise;
}

子控制器：

.controller('shareCtrl', function($scope){
    $scope.layout.toggleStatusSuggestion = function(){
         $scope.model.getRandomStatus().then(function(data){
            console.log(data);//logs out the correct text
            //$scope.model.formData.shareStatus = data;//also tried this, no luck
            return data.message;
         });
    $scope.model.formData.shareStatus = $scope.layout.toggleStatusSuggestion();//Newly edited
    }
});

HTML：

<div class="shareContainer" data-ng-controller="shareCtrl">
 <textarea class="textAreaExtend" name="shareStatus" data-ng-model="model.formData.shareStatus" data-ng-init="model.formData.shareStatus = layout.toggleStatusSuggestion()" cols="4"></textarea>
</div>

最佳答案

我相信您想要的是：

$scope.model.getRandomStatus().then(function(data){
            $scope.model.formData.shareStatus = data.message;

});

从then内部返回内容不会从包装它的函数中返回任何内容，因此不执行任何操作
