要实现中文排序的功能,需要重写Ext.data.Store的applySort函数,可以把它放在ext-all.js文件的最后,或者是放到HTML页面的最上面,要在ExtJS初始化之后,实际代码调用之前执行,这样重写的方法才能起作用,中文排序也就实现了。完整的实现代码如下:

<script type="text/javascript" src="../ext-3.4.0/adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="../ext-3.4.0/ext-all.js"></script>
<script type="text/javascript">
Ext.data.Store.prototype.applySort=function(){//重载applySort
 if(this.sortInfo && !this.remoteSort){
  var s = this.sortInfo, f=s.field;
  var st=this.fields.get(f).sortType;
  var fn=function(r1,r2){
   var v1=st(r1.data[f]),v2=st(r2.data[f]);
   //添加:修复汉字排序异常的Bug
   if(typeof(v1)=="string"){//若为字符串
    return v1.localeCompare(v2);//则localeCompare比较汉字字符串,Firefox与IE均支持
    
   }//添加结束
   return v1>v2 ? 1 : (v1<v2 ? -1 : 0);
  };
  this.data.sort(s.direction,fn);
  if(this.snapshot && this.snapshot!=this.data){
   this.snapshot.sort(s.direction,fn);
  }
  
 }
};
</script>
<script type="text/javascript">
Ext.onReady(function(){
 var cum = new Ext.grid.ColumnModel([
  {header:"项目ID",dataIndex:'project_id'},
  {header:"项目名称",dataIndex:'project_name'},
  {header:"部门",dataIndex:'project_dept_no'},
  {header:"项目经理",dataIndex:'project_manager'},
  {header:"开发经理",dataIndex:'project_leader'}
]);

 var cumdata=[
  ['1','教学管理系统','001','李润','田成功'],
  ['2','留言系统','002','光明','周爱卿'],
  ['3','图书管理系统','008','毛小强','黄岩'],
  ['4','校信通','003','王磊','郭强']
];

 var store=new Ext.data.Store({
  proxy:new Ext.data.MemoryProxy(cumdata),
  reader:new Ext.data.ArrayReader({},[
   {name:'project_id'},
   {name:'project_name'},
   {name:'project_dept_no'},
   {name:'project_manager'},
   {name:'project_leader'}
  ]),
  sortInfo:{field:'project_name',direction:'ASC'}//设置project_name字段,按升序排列
});

 store.load();

 var cumgrid =new Ext.grid.GridPanel({
  renderTo:'cumGrid',
  store:store, 
  height:200,
  width:500,
  colModel:cum
});
});
</script>
</head>
<body>
<div id="cumGrid"></div>
