Extjs Gird supports Chinese pinyin sorting implementation code

<script type="text/javascript">
=function(){//Overload applySort
if( && !){
var s = , f=;
var st=(f).sortType;
var fn=function(r1,r2){
var v1=st([f]),v2=st([f]);
//Add: Fix the bug of abnormal Chinese character sorting
if(typeof(v1)=="string"){//If it is a string
return (v2);// Then localeCompare compares Chinese character strings, both Firefox and IE support it
}//Add to end
return v1>v2 ? 1 : (v1<v2 ? -1 : 0);
};
