EXTjs4.0的store的findRecord的BUG演示代码

findRecord: function() {
var me = this,
index = me.find.apply(me, arguments);
return index !== -1 ? me.getAt(index) : null;
},

find: function(property, value, start, anyMatch, caseSensitive, exactMatch) {
var fn = this.createFilterFn(property, value, anyMatch, caseSensitive, exactMatch);
return fn ? this.data.findIndexBy(fn, null, start) : -1;
},
createFilterFn方法
createFilterFn: function(property, value, anyMatch, caseSensitive, exactMatch) {
if (Ext.isEmpty(value)) {
return false;
}
value = this.data.createValueMatcher(value, anyMatch, caseSensitive, exactMatch);
return function(r) {
return value.test(r.data[property]);
};
},
findIndexBy : function(fn, scope, start){
var me = this,
keys = me.keys,
items = me.items,
i = start || 0,
len = items.length;

for (; i < len; i++) {
if (fn.call(scope || me, items[i], keys[i])) {
return i;
}
}
return -1;
},

for (; i < len; i++) {
if (fn.call(scope || me, items[i], keys[i])) {
return i;
}
},

var value=new RegExp('1');
var b=value.test('15')//这个是返回成功的。
