extjs:通过从 Ext.data.JsonStore 返回的 json 加载树
我有一个 extjs TreePanel,需要使用从 Ext.data.JsonStore 调用返回的 json 数据(跨域调用)加载。效果很好。我只是找不到使用返回的 jsonStore 加载树面板的方法。有什么想法吗?我真是亡命之徒。
谢谢大家!
代码片段:
var store = new Ext.data.JsonStore({
root: 'topics',
totalProperty: 'totalCount',
idProperty: 'threadid',
remoteSort: true,
fields: [
'title', 'forumtitle', 'forumid', 'author',
{name: 'replycount', type: 'int'},
{name: 'lastpost', mapping: 'lastpost', type: 'date', dateFormat: 'timestamp'},
'lastposter', 'excerpt'
],
proxy: new Ext.data.ScriptTagProxy({
url: 'http://other.domain/test.aspx'
})
});
// 现在我需要使用该存储来加载树...
var Tree = Ext.tree;
var tree = new Tree.TreePanel({
useArrows: true,
autoScroll: true,
animate: true,
enableDD: true,
containerScroll: true,
border: false,
loader: new Tree.TreeLoader({ dataUrl: '????' })
//.....
});
救命!
i have a extjs TreePanel that i need to load using json data (cross-domain call) returned from my Ext.data.JsonStore call. That works perfectly. I just cant find a way to use the returned jsonStore to load the treepanel. Any ideas? I am real desperado.
Thanks everyone!
code snippet:
var store = new Ext.data.JsonStore({
root: 'topics',
totalProperty: 'totalCount',
idProperty: 'threadid',
remoteSort: true,
fields: [
'title', 'forumtitle', 'forumid', 'author',
{name: 'replycount', type: 'int'},
{name: 'lastpost', mapping: 'lastpost', type: 'date', dateFormat: 'timestamp'},
'lastposter', 'excerpt'
],
proxy: new Ext.data.ScriptTagProxy({
url: 'http://other.domain/test.aspx'
})
});
// Now i need to use that store to load the tree...
var Tree = Ext.tree;
var tree = new Tree.TreePanel({
useArrows: true,
autoScroll: true,
animate: true,
enableDD: true,
containerScroll: true,
border: false,
loader: new Tree.TreeLoader({ dataUrl: '????' })
//.....
});

您必须向存储添加一个加载侦听器,并手动将加载数据中的树节点添加到树中,该树不直接支持存储,请记住,树是分层的,并且存储非常平坦。
You would have to add a load listener to the store and manually add tree nodes from the loaded data into the tree, the tree does not support stores directly, remember that tree's are hierarchical and stores and pretty flat.
