javascript - 在AngularJS中，模型更新后如何更新 View ？

Question

在下面的代码片段中，两个变量 $scope.recordList 和 $scope.recordList2 具有完全相同的值。 $scope.recordList2 已设置静态值，$scope.recordList 在收到服务器响应后更新。语句 $scope.recordList 和 $scope.recordList2 呈现相同的值，$scope.recordList 在收到响应后呈现。

最后有两个智能表( https://github.com/lorenzofox3/Smart-Table )。 $scope.recordList2 基表按预期工作。基于 $scope.recordList 的表无法按预期工作。

在AngularJS中，模型更新后如何更新 View ？

<div ng-app="smartTableApp" ng-controller="smartTableController">
    <script>  
        angular.module('smartTableApp', [ 'AngularJSRemoting','smartTableApp.controllers', 'smartTable.table']);
        angular.module('smartTableApp.controllers', []).controller('smartTableController', function($scope, jsr) {

        jsr.Call('appController.query', '{!soql}').then(function(response) {
            $scope.recordList = response;
            //$scope.$apply() ; uncommenting this gives "$digest already in progress" error
        },function(err){
            console.log(err);
        });

        $scope.recordList2=[{"attributes":{"type":"Contact","url":"/services/data/v30.0/sobjects/Contact/0039000000wvt6yAAA"},"Name":"Stella Pavlova","Phone":"(212) 842-5500","CreatedDate":"2014-05-15T06:17:48.000+0000","Id":"0039000000wvt6yAAA"},{"attributes":{"type":"Contact","url":"/services/data/v30.0/sobjects/Contact/0039000000wvt6zAAA"},"Name":"Lauren Boyle","Phone":"(212) 842-5500","CreatedDate":"2014-05-15T06:17:48.000+0000","Id":"0039000000wvt6zAAA"},{"attributes":{"type":"Contact","url":"/services/data/v30.0/sobjects/Contact/0039000000wvt70AAA"},"Name":"Babara Levy","Phone":"(503) 421-7800","CreatedDate":"2014-05-15T06:17:48.000+0000","Id":"0039000000wvt70AAA"},{"attributes":{"type":"Contact","url":"/services/data/v30.0/sobjects/Contact/0039000000wvt71AAA"},"Name":"Josh Davis","Phone":"(503) 421-7800","CreatedDate":"2014-05-15T06:17:48.000+0000","Id":"0039000000wvt71AAA"},{"attributes":{"type":"Contact","url":"/services/data/v30.0/sobjects/Contact/0039000000wvt72AAA"},"Name":"Jane Grey","Phone":"(520) 773-9050","CreatedDate":"2014-05-15T06:17:48.000+0000","Id":"0039000000wvt72AAA"}] ;

    });
    </script>   
    <br/>----------recordList----------<br/><!-- Shows expected values -->
    {{recordList}}
    <br/>----------recordList2----------<br/><!-- Shows expected values -->
    {{recordList2}}
    <br/><br/>
    <smart-table rows="recordList" ></smart-table><br/><br/><!-- table is NOT rendered -->
    <smart-table rows="recordList2" ></smart-table><br/><br/><!-- table is rendered -->       
</div>

Answer 1

问题不在于 Angular 没有更新 View 。事实上，您在代码示例中指出它正在更新它:

<br/>----------recordList----------<br/><!-- Shows expected values -->
{{recordList}}

我没有使用 Smart-Table 的经验，但我确实找到了 this issue GitHub 上有报道，它描述了与您类似的问题。该模块的作者确实回复了，并建议仅使用列配置来初始化表，以避免出现此问题(他将其描述为错误)。

因此，如果您在查询之前了解数据的结构，则应该使用列数据初始化表。
