假设我的数据源如下:
var data = [
{
id: 1,
name: 'name1',
parentId: null,
children: [
{
id: 2,
name: 'name2',
parentId: 1
}
]
},
{
id: 3,
name: 'name3',
parentId: null,
children: [
{
id: 4,
name: 'name4',
parentId: 3
}
]
}
]
代码片段如下:
var basic_grid_store = Ext.create('Ext.data.TreeStore', {
storeId: 'basic_grid_store',
model: 'TestModel',
root: {
children: []
}
});
console.log(data);
// the data structure is correct at this time
basic_grid_store.setRootNode({children: data);
console.log(data);
// the data structure is incorrect at this time, in which the `children` attribute for each item was gone.
我找不到任何相关的文档,有人可以说明为什么TreeStore
修改了我的数据源,因为它不应该发生?
答案 0 :(得分:0)
是的,它 更改了原始数组。我无法回答为什么会出现这种情况,你需要问Ext架构师/开发人员,但你能尝试的是:
basic_grid_store.setRootNode({children:Ext.clone(data)});
