從書中看到這個通過重寫Ext.data.Store的applySort函數(shù)實現(xiàn)Grid支持中文排序，摘抄下來。以備不時之需。
1
Ext.data.Store.prototype.applySort = function()
{
2
if(this.sortInfo && !this.remoteSort){
3
var s = this.sortInfo, f = s.field;
4 var st = this.fields.get(f).sortType;
5 var fn = function(r1,r2){
6 var v1 = st(r1.data[f]),v2 = st(r2.data[f]);
7 if(typeof(v1)=="string"){
8 return v1.localeCompare(v2);
9
}
10 return v1 > v2 ?1:(v1 < v2?-1:0);
11 };
12 this.data.sort(s.direction, fn);
13 if(this.snapshot && this.snapshot != this.data){
14 this.snapshot.sort(s.direction,fn);
15 }
16 }
17
}
這段代碼可以放在ext-all.js文件的最后，或放到html頁面的最上面。主要是要在EXT初始化之后，實際代碼調(diào)用之前執(zhí)行。
附例如下：
