TreeGrid：设置数据根没有效果 [英] TreeGrid: setting data root has no effect

问题描述

我正在尝试设置一个TreeGrid，我的数据对象如下所示：

I'm trying to setup a TreeGrid, my data object looks like this:

{
    "code": "success",
    "data": {
        "text": ".",
        "children": [
            {
                "clientname": "Market",
                "contact": "OpenX Market Advertiser",
                "email": "[e-mail]",

我需要告诉Ext它应该使用数据作为根元素：

I need to tell Ext that it should use data as the root element:

var store = Ext.create('Ext.data.TreeStore', {
    model: 'Task',
    proxy: {
        type: 'ajax',
        url: 'http://localhost/rocketads/trunk/advertisers/index/stats:true/',
        reader:{
            type:'json',
            root:'data'
        }
    },
});

这对我来说并不适用，尽管我正常使用这种方法。

This doesn't work for me although I'm successfully using this with normal Stores.

推荐答案

不幸的是，使用TreeStore，无论您用于root还是用作每个后续级别的根，因此可能会找到根节点，然后找不到其数据属性。将顶级属性从数据更改为子项或将每个子实例更改为数据。

Unfortunately with a TreeStore, whatever you use for root is also used as the root for each subsequent level, so it's probably finding the root node, then not finding its data property. Either change the top level property from data to children or change each instance of children to data.
