现在的问题是在数据库中读取到有没有checked权限倒是正确地显示，但是已经勾选的数据并没有传到后台,记得有一次传输到了，但是有些误差，后面再调就不出来了，第一次用，求教。JS代码
Ext.require([//加载指定组件
'Ext.tree.*',
'Ext.data.*',
'Ext.window.MessageBox'
]);
Ext.onReady(function() {//在页面加载完毕后执行，若有多个依次执行
var store = Ext.create('Ext.data.TreeStore', {
proxy: {
type: 'ajax',
url: 'check-nodes.json'
},
sorters: [{
property: 'leaf',
direction: 'ASC'
}, {
property: 'text',
direction: 'ASC'
}]
});
var tree = Ext.create('Ext.tree.TreePanel', {
store: store,
rootVisible: false,
useArrows: true,
frame: true,
title: 'Check Tree',
renderTo: 'tree-div',
width: 300,
height: 350,
dockedItems: [{
xtype: 'toolbar',
items: {
text: 'Get checked nodes',
handler: function(){
var records = tree.getView().getChecked(),
names = [];
Ext.Array.each(records, function(rec){
names.push(rec.get('text'));
});
Ext.MessageBox.show({//采用config配置的形式自定义对话框 异步机制
title: 'Selected Nodes',
msg: names.join('<br />'),
icon: Ext.MessageBox.INFO
});
}
}
}]
});
});
