我正在尝试将数据加载到 extjs 4TreeStore
中,但是在附加节点时node.updateInfo is not a function
出现错误。
我的模型类如下:
维度.js
Ext.define('ilp.model.Dimension', {
extend : 'Ext.data.Model',
require : [
'ilp.model.DimensionLevel'
],
fields : [
'actualName',
'displayName'
],
hasMany : {model : 'ilp.model.DimensionLevel', name : 'dimensionLevels'}
});
DimensionLevel.js
Ext.define('ilp.model.DimensionLevel', {
extend : 'Ext.data.Model',
fields : [
{name : 'name', type : 'string'},
{name : 'totalTrainees', type : 'int'}
]
});
树存储代码如下:
Ext.define('ilp.store.DimensionTree', {
extend : 'Ext.data.TreeStore',
requires : [
'ilp.model.Dimension',
'ilp.model.DimensionLevel'
],
model : 'ilp.model.Dimension',
root: {
name: 'Dimensions'
},
proxy: {
type: 'ajax',
url: 'http://localhost:8080/pentaho/content/cda/doQuery',
reader: {
type: 'pentahoReader',
root: 'resultset'
},
extraParams: {
path: 'RINXDashboards%2FCDAs%2FILP_Employee_Qeries.cda',
dataAccessId:'Get_All_Levels_From_All_Dimensions',
userid : 'joe',
password : 'password'
}
},
listeners: {
append : function(parentNode, newNode, index, options) {
if(newNode.get('text') != 'Root') {
console.log('newNode text value = ' + newNode.get('text'));
newNode.set('checked', null);
newNode.set('expandable', true);
if(Ext.ClassManager.getName(newNode) == "ilp.model.Dimension") {
newNode.set('expanded', true);
newNode.set('text', newNode.get('displayName'));
if(newNode.dimensionLevels().getCount() > 0) {
newNode.dimensionLevels().each(function(level) {
newNode.appendChild(level);
});
} else {
newNode.set('leaf', true);
}
}else if(Ext.ClassManager.getName(newNode) == "ilp.model.DimensionLevel") {
newNode.set('leaf', true);
newNode.set('text', newNode.get('name'));
}
}
}
}
});
我在以下行遇到错误:
newNode.dimensionLevels().each(function(level) {
在调试时我发现updateInfo()
方法newNode
是undefined
.
谁能告诉我为什么会出现这个错误?我现在完全无能为力了!!!
