Question

Ext js TreeStore未加载

Ext.ns('App');

Ext.onReady(function() {
  Ext.QuickTips.init();
  App.PPPExplorer.init(); 
});


App.PPPExplorer = {

// Initialize application
init : function(serverCfg) {        
    this.PPP = this.createPPP();
},

createPPP : function() {


// Set up a model to use in our Store
Ext.define('Summary', {
  extend: 'Ext.data.Model',
  fields: [
     {name: 'pid', type: 'string'}
  ]
});

var myStore = Ext.create('Ext.data.TreeStore', {
 model: 'Summary',
 storeId:'myStore',
 proxy: {
     type : 'ajax',
     method: 'GET',
     url: '/Explorer.do?method=getPPP&search=true',
     reader: {
         type: 'json'
     },
     root: {
         pid: 'src',
         text:'test',
         expanded: true
     },
 },
 autoLoad: true
 });

Ext.create('Ext.tree.Panel', {
    title: 'Simple Tree',
    width: 200,
    height: 150,
    store: myStore,
//      rootVisible: true,
    renderTo: 'Explorer',


        columns: [{
             xtype: 'treecolumn', //this is so we know which column will show the tree
             text: 'Reference',
             flex: 2,
             sortable: true,
             dataIndex: 'pid',
             locked: true
        }]
});


  }
}

我正在使用Ext js 4.2版本

我在上面的代码中使用了treeStore，treePanel，不知何故代理调用没有发送到Server。控制台中没有错误消息

提前致谢

根定义应该在TreeStore 定义中，如下所示（现在在代理声明中）：

var myStore = Ext.create('Ext.data.TreeStore', { model: 'Summary', storeId: 'myStore', proxy: { type: 'ajax', method: 'GET', url: '/Explorer.do?method=getPPP&search=true', reader: { type: 'json' } }, autoLoad: true, root: { pid: 'src', text: 'test', expanded: true }

}）;

您的代码可以正常运行，see it here
