javascript - NG-Table的例子说明

Question

有人可以解释这个例子

Plunker NG-Table

在 HTML 中，有 -->

<tbody ng-repeat="group in $groups">

但是在js中没有为什么？

$groups

Answer 1

ngTable module在指定 groupBy ngTableParameter ( you can see it in the github source code here ) 时定义 $scope.$groups。

$scope.tableParams = new ngTableParams({
    page: 1,            // show first page
    count: 10          // count per page
}, {
    groupBy: 'role',   // << ----- grouping parameter
    total: data.length,
    getData: function($defer, params) {
        var orderedData = params.sorting() ?
                $filter('orderBy')(data, $scope.tableParams.orderBy()) :
                data;

        $defer.resolve(orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count()));
    }
});

这是 ngTable 在 $scope 上为 plunker 示例中的数据创建的 $groups。

$scope.$groups = [
            {
                value: 'Administrator',
                data: [
                    {name: "Moroni", age: 50, role: 'Administrator'},
                    {name: "Tiancum", age: 43, role: 'Administrator'},
                    {name: "Jacob", age: 27, role: 'Administrator'}
                ]
            },
            {
                value: 'Moderator',
                data: [
                    {name: "Nephi", age: 29, role: 'Moderator'},
                    {name: "Nephi", age: 29, role: 'Moderator'},
                    {name: "Tiancum", age: 43, role: 'Moderator'},
                    {name: "Enos", age: 34, role: 'Moderator'}
                ]
            },
            {
                value: 'User',
                data: [
                    {name: "Enos", age: 34, role: 'User'},
                    {name: "Tiancum", age: 43, role: 'User'},
                    {name: "Jacob", age: 27, role: 'User'},
                    {name: "Enos", age: 34, role: 'User'},
                    {name: "Jacob", age: 27, role: 'User'},
                    {name: "Nephi", age: 29, role: 'User'},
                    {name: "Tiancum", age: 43, role: 'User'},
                    {name: "Jacob", age: 27, role: 'User'},
                    {name: "Nephi", age: 29, role: 'User'},
                    {name: "Enos", age: 34, role: 'User'}
                ]
            }
        ]
