Question

给出以下JSON数据：

[
{
    "pk": 2, 
    "model": "corkboard.announcement", 
    "fields": {
        "body": "Test announcement 2 body.", 
        "date": "2012-04-10T00:59:12Z", 
        "title": "Test Announcement 2"
    }
}, 
{
    "pk": 1, 
    "model": "corkboard.announcement", 
    "fields": {
        "body": "Test Announcement 1 body.", 
        "date": "2012-04-10T00:58:56Z", 
        "title": "Test Announcement 1"
    }
}
]

我正在创建一个dojox / DataGrid，但我似乎无法找到一种方法来访问“字段”的孩子。

这是javascript：

<script>
        var announcementStore, dataStore, grid;
        require(["dojo/store/JsonRest", "dojo/store/Memory", "dojo/store/Cache", "dojox/grid/DataGrid", "dojo/data/ObjectStore", "dojo/query", "dojo/domReady!"], 
            function(JsonRest, Memory, Cache, DataGrid, ObjectStore, query){
            announcementStore = Cache(JsonRest({target:"/corkboard/announcements/"}), Memory());
            grid = new DataGrid({
                store: dataStore = ObjectStore({objectStore: announcementStore}),
                structure: [
                    {name:"Title", field:"title", width: "200px"},
                    {name:"Body", field:"body", width: "200px", editable: true}
                ]
            }, "target-node-id");
            grid.startup();
            query("#save").onclick(function(){
                dataStore.save();
            });
        });
</script>

我在定义字段时尝试使用fields.title和fields.body，但这不起作用。

在这个例子中，我如何访问“fields”孩子？

您需要在网格结构中使用formatter方法，如下所示。

{name:"Title",field:"_item",widht:"200px",formatter:function(item){return item.fields.title}}

请记住，您需要在_item中传递field，这将在格式化程序方法中为您提供整行，并使用点表示法，您可以返回已重新获取的数据

带有dojo / data / ObjectStore的JSON子对象
