Ext出错情况和解决办法大全

错误1

Error: [Ext.Loader] Failed loading synchronously via XHR: 'http://localhost:8080/GinPlusTest/ext-4.2/src/data/model.js'; please verify that the file exists. XHR status code: 404

错误1的解决办法

该错的意思是找不到data.model.js，肯定在某些model中，继承了错误的model，如

Ext.define('AM.model.Company',{
  extend: 'Ext.data.model',
  fields:[
  {name:'id'},
  {name:'text'},
  {name:'parent_id'},
  {name:'expanded'},
  {name:'leaf'}
  ]
 })

中

把extend:'Ext.data.model'改为'Ext.data.Model'就正确了
