EXTJS中文排序会出问题

学习EXTJS有一段时间了，遇到了两个问题，一个是点击列表栏该列进行排序，中文排序会出问题，需要在自己的程序中或者在extjs-all.js中添加代码:

Ext.data.Store.prototype.applySort = function() {
    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]);
            if (typeof(v1) == "string") {
                return v1.localeCompare(v2);
            }
            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);
        }
    }
};

另一个问题是ext默认label没有click事件，要想添加事件，同样在ext-all.js中添加一段代码即可：

Ext.form.Label.prototype.afterRender = Ext.form.Label.prototype.afterRender
     .createSequence(function() {
        this.relayEvents(this.el, ['click']);
       });

                                         };
