我的fuelux数据网格在主干渲染功能中看起来像这样

    var dataSource = new StaticDataSource({
            columns: [
                                     {
                                           property: 'id',
                                           label: 'id',
                                          sortable: true
                                     },
                {
                    property: 'name',
                    label: 'groups',
                    sortable: true
                },
                {
                    property: 'name',
                    label: 'Roles',
                    sortable: true
                }
            ],
            data: this.collection,
            delay: 250
        });
        $('#sectionName').html('Groups');
        $('#MyGrid').datagrid({
            dataSource: dataSource,
            stretchHeight: true
        });

this.collection 返回 json 如下

[
{
    "id":1,
    "roles":[
                {"id":1,"authority":"ROLE1"},
                {"id":2,"authority":"ROLE2"},
                {"id":3,"authority":"ROLE3"}
            ],
    "groups":[
                {"id":1,"name":"A"},
                {"id":2,"name":"B"},
                {"id":3,"name":"C"}
          ]
},
{
    "id":2,
    "roles":[
                {"id":5,"authority":"ROLE4"},
                {"id":5,"authority":"ROLE5"},
                {"id":6,"authority":"ROLE6"}
            ],
    "groups":[
                {"id":4,"name":"D"},
                {"id":5,"name":"E"},
                {"id":6,"name":"F"}
          ]
}

]

我希望fuelux datagrid 具有列ID、角色和组。它应该如下所示：

    id        roles                        groups
    1         role1, role2 , role3          A, B, C
    12        role3, role4 , role5          D, E, F

我试图编写类似这样的格式化程序函数，但它不起作用

 var dataSource = new StaticDataSource({
        columns: [
            {
                property: 'id',
                label: 'id',
                sortable: true
            },
            {
                property: 'name',
                label: 'groups',
                sortable: true
            },
            {
                property: 'name',
                label: 'Roles',
                sortable: true
            }
        ], 

       formatter: function (items) {
                $.each(items, function (index, item) {
                                    item.roles= //string made from groups with comma
                    item.groups= //string made from roles with comma

            },
        data: this.collection,
        delay: 250
    });

    $('#MyGrid').datagrid({
       //as above
    });
  formatter: function (items) {
                $.each(items, function (index, item) {
                   item.roles= //string of roles made from roles with comma
                                   item.groups= /string of groups made from groups with comma 
                });
            },

如果这里有人可以帮助我，那将是很大的帮助。

我已经能够解决我的问题如下

 formatter: function (items) {
                $.each(items, function (index, item) {
                    var roleCell = new app.RoleSupplier({ model: item      });
                    roleCell.render();
                    item.roles = roleCell.$el; //set property name above to roles
                });
            },

然后，我创建了 RoleSupplier 如下

 app.RolesSupplier = Backbone.View.extend({
    template: _.template($('#roles-cell-template').html()),
    render: function (eventName) {
        this.$el.html(this.template(this.model.toJSON()));
    }
});

我创建了如下模板

 <script type="text/template" id="roles-cell-template">
        <div>
            <@ _.each(roles.toJSON(), function( role, index, list ){ @>
                <@ if(index < (list.length - 1)) { @>
                    <@=role.authority + ','@>
                <@ } else { @>
                    <@=role.authority@>
                <@ } @>
            <@ }); @>

        </div>  
    </script>

这对我有用。但是，fuelux 的用户必须了解的是：

  • 您可以将属性名称设置为 json 中的键名称以设置其值

    property:'id', label:'ID' //将id值设置为列名ID

  • 如果你有一些 json 值并且你想以特定的方式显示它们，或者你不能在单元格中使用一些 html，你可以将它们格式化如下

    formatter: function (items) {
                $.each(items, function (index, item) {
                     item.yourPropertyName1= format your html here that you want  appear in label1
                     item.yourProeprtyName 2= fromat your html like button , anything you want inside column cell of label2                 
                });
            },

对于您的列定义，每个property都应与您的数据源返回的属性名称相匹配。尝试这个：

{
    property: 'id',
    label: 'ID',
    sortable: true
},
{
    property: 'roles',
    label: 'Roles',
    sortable: true
},
{
    property: 'groups',
    label: 'Groups',
    sortable: true
}
