The findRecord: function() method is called in the findRecord method

Copy code The code is as follows: findRecord: function() {

var me = this,

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

 
Enter the find method 

Copy the code The code is as follows: 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 method
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; 
}, 

 
Please note
value.test(r.data[property]); the BUG occurs here

The property I use here is the "ID" field.
Here It is to query the record with ID==1,
It is done through this loop

Copy code The code is as follows : for (; i < len; i ) {

if (fn.call(scope || me, items[i], keys[i])) {

 return i; 
} 
}, 

 
That is, 
value.test(r.data[property]) is called every time 

This judgment is made through regular expressions
You can test this situation

Copy the code The code is as follows: var value=new RegExp('1');

var b=value.test('15')//This is returned successfully.

 
I think everyone knows the reason. 
When it is judged that ID=1, when an ID starting with 1 is encountered, a problem will be determined at this time.
