Javascript 异步服务调用后未定义ngHandsontable数据行

我有一个简单的控制器，它通过ajax调用来获取ngHandsontable的表数据，但是

datarows

值是

undefined

var app = angular.module('propnet', [
    'ngRoute',
    'ngHandsontable'
]);
// configure our routes
app.config(function($routeProvider)
{
    $routeProvider.    
    // route for the about page
    when('/property/:prop_id',
    {
        templateUrl: 'pages/property.html',
        controller: 'propertyController'
    })
...

app.controller('propertyController', function($scope, $routeParams, $http, $log)
{
    $http.get('api/Transactions/property/' + $routeParams.prop_id).success(function(data)
    {
        $scope.transactions = data;
        $log.log("Got some txns" + data);
    });

});

页面/property.html

：

<div class="row">{{ transactions }}</div>
<div class='row'>
    <hot-table col-headers="showColHeaders" datarows="transactions">
        <hot-column data="itemName" title="'Name'" type="'text'" read-only></hot-column>
         <hot-column data="amount" title="'Amount'" type="'numeric'" format="'$ 0,0.00'" read-only></hot-column>
         <hot-column data="date" title="'Date'" type="'date'" dateFormat="'YYYY-MM-DD'"></hot-column>
         <hot-column data="vendorName" title="'Vendor'"></hot-column>
         <hot-column data="notes" title="'Notes'"  width="150" ></hot-column>
    </hot-table>
</div>

为什么

$scope.transactions

没有绑定到

datarows

---

相关：

初始化控制器中的$scope.transactions=[]。最初，当handsontable尝试绑定数据时，$scope.transactions未定义。因此，首先初始化它有助于通过错误。一旦GET方法返回数据，handsontable将用数据填充表。

可能与（感谢@Suppressingfire）初始化

$scope有关。transactions

修复了错误，但表中仍然没有数据。事实证明，我必须（？）在控制器中指定

minSpareRows

以满足第253行条件：

if（oldValue.length==scope.htSettings.minSpareRows&&newValue.length！=scope.htSettings.minSpareRows）{scope.htSettings['data']=scope.datarows；

Got some txns[object Object],[object Object],[object Object],[object Object]
