ExtJs: Search / Filter within a ComboBox

Question

I\'ve the following problem / question in ExtJs 2.3:

I\'d like to do a search within a combobox. I\'ll give you an example:

Ext.comboData.names = [[\         


        

Answer 1

ExtJS ComboBox has a keydown event (and keyup, and keypress) that you can use for this purpose.

ExtJS SimpleStore also has a filter method that should suit your purpose. You can use it like this (to find values that contain an 'a' character):

store.filter('name', 'a', true, true)

First parameter is the record field, second is the string/regexpt to look for, third parameter means that filter should match any part of field (instead of just the beginning of the value), and the last value determines the case-sensitivity. You can turn it off, of course, if you like.

All of this applies to ExtJS 2.3.0. Hopefully this will get you started.
