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:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<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([
