javascript - 未捕获的类型错误 : Cannot read property 'row' of undefined is not working in angular js

Question

我想读取数据表中的行值，因为我实现了类似的东西。

$('#entry-grid').on('click', '.check', function () {
        var row = $(this).closest("tr");            
        var data = $scope.dtInstance.DataTable.row.data();
        alert(data);
    })   

下面是我的 table

<table id="entry-grid" datatable="" dtinstance="dtInstanceCallback" dt-options="dtOptions" dt-columns="dtColumns" class="table table-hover"></table>

但是在调试时我收到错误

Uncaught TypeError: Cannot read property 'row' of undefined

不知道为什么会出现错误

更新

这是我更新的 anuglar 代码，我正在尝试解决它，但事实并非如此。

var app = angular.module('MyApp', ['datatables']);
app.controller('homeCtrl', ['$scope', '$http', 'DTOptionsBuilder', 'DTColumnBuilder',
    function ($scope, $http, DTOptionsBuilder, DTColumnBuilder) {
        $scope.dtColumns = [
            DTColumnBuilder.newColumn(null, '').renderWith(function(data, type, full) {
                return '<input type="checkbox" class="check" data-object-id="'+full.objectid+'">'
            }),
            DTColumnBuilder.newColumn("OBJECTID", "ID"),
            DTColumnBuilder.newColumn("SERVICE_CODE", "Service Code"),
            DTColumnBuilder.newColumn("COND1", "Condition 1"),
            DTColumnBuilder.newColumn("COND2", "Condition 2"),
            DTColumnBuilder.newColumn("COND3", "Condition 3"),
            DTColumnBuilder.newColumn("SERVICE_TYPE", "Service type"),
            DTColumnBuilder.newColumn("REMARK", "Remark"),
            DTColumnBuilder.newColumn("DESCRIPTION", "Description")
        ]
        $scope.dtOptions = DTOptionsBuilder.newOptions().withOption('ajax', {
            url: "/home/getdata",
            type: "POST"
        })
        .withPaginationType('full_numbers')
        .withDisplayLength(10);

        $scope.dtInstance = {};
        $scope.dtIntanceCallback = function (instance) {
            $scope.dtInstance = instance;            
        }
        $scope.dtRebind = function () {
            $scope.dtInstance.DataTable.draw()
        }

        $('#entry-grid').on('click', '.check', function () {
            var row = $(this).closest("tr");
            var data = $scope.dtInstance.DataTable.row().data(); // here is the error of row undefined            
        })        
    }])

如果我没记错的话，正确使用的指令应该是 dt-instance 而不是 dtinstance，因为您将其作为 $scope.dtInstance 访问 是驼峰式的，所以等效的指令是 kebab 式的。

<table id="entry-grid" datatable="" dt-instance="dtInstanceCallback" dt-options="dtOptions" dt-columns="dtColumns" class="table table-hover"></table>
