EXTJS4 - For TreeStore, how to pass parameters and action methods?
提问by Riyaz Ahamed
I am using Extjs4 TreeStore, i want to know how to pass parameters (like mode = 'list') and action methods (POST or GET).
我正在使用 Extjs4 TreeStore，我想知道如何传递参数（如 mode = 'list'）和操作方法（POST 或 GET）。
Thanks in advance.
提前致谢。
EXTJS 3.x i have used like this it's working fine:
EXTJS 3.xi 像这样使用它工作正常：
loader: new Ext.tree.TreeLoader({
dataUrl: 'content/permissions/server.php',
baseParams: {
mode: 'getPermissions'
}
})
EXTJS 4.x i have used like this but it is not working:
EXTJS 4.xi 已经这样使用了，但它不起作用：
Ext.create('Ext.data.TreeStore', {
autoLoad: true,
proxy: {
type: 'ajax',
url: 'server.php'
},
extraParams: {
mode: 'getTree'
},
actionMethods: 'POST',
root: {
text: 'Tree',
id: 'src',
expanded: true
}
});
Thanks, Riyaz

This the correct one
这是正确的
Ext.create('Ext.data.TreeStore', {
autoLoad: true,
proxy: {
type: 'ajax',
url: 'server.php',
extraParams: {
mode: 'getTree'
},
actionMethods: 'POST'
},
root: {

You should carefully check your configuration parameters with the current Ext JS 4 API Documentation.
您应该使用当前的Ext JS 4 API 文档仔细检查您的配置参数。
What I see at first glance:
我第一眼看到的：
actionMethodsis an object and not a string value configuration. It's implemented in both the AJAX and the REST proxies. If your need a full featured editable tree, consider a RESTproxy. Only if you go beyond CRUD, you need to provide additional
actionMethodsto the REST proxy.extraParamsbelongs to the Proxy and not to the tree configuration.
actionMethods是一个对象，而不是一个字符串值配置。它在 AJAX 和 REST 代理中实现。如果您需要功能齐全的可编辑树，请考虑使用REST代理。只有当您超越 CRUD 时，您才需要提供额外
actionMethods的 REST 代理。extraParams属于代理而不是树配置。
So your store configuration should look like:
所以你的商店配置应该是这样的：
Ext.create('Ext.data.TreeStore', {
autoLoad: true,
proxy: {
type: 'ajax',
url: 'server.php',
extraParams: {
mode: 'getTree'
},
},
root: {
text: 'Tree',
id: 'src',
expanded: true
}
});
Have you verified if at least an Ajax request has been sent to the server? You can easily check this with FireBug.
您是否已验证是否至少有一个 Ajax 请求已发送到服务器？您可以使用FireBug轻松检查这一点。

example of correct setting:
正确设置示例：
actionMethods: {

create: 'POST',
update: 'POST',
read: 'GET'
},
