我有一个简单的控制器，它调用ajax来获取ngHandsontable的表数据，但lib.quotedFormOf(s)值为datarows。
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;
$log.log("Got some txns" + data);
});
});
：
pages/property.html <div class="row">{{ transactions }}</div>
<div class='row'>
<hot-table col-headers="showColHeaders" datarows="transactions">
<hot-column data="itemName" title="'Name'" type="'text'" read-only></hot-column>
<hot-column data="amount" title="'Amount'" type="'numeric'" format="'$ 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>
打印从服务调用返回的值，但{{ transactions }}为空，ngHandsontable抛出错误（多次）：
<hot-table>为什么Got some txns[object Object],[object Object],[object Object],[object Object]

没有绑定到$scope.transactions？
答案 0 :(得分：1)
在控制器中初始化$ scope.transactions = []。最初当handsontable尝试绑定数据时，$ scope.transactions是未定义的。因此，通过初始化它首先有助于传递错误。一旦GET方法返回数据，handontable将用数据填充表。
