I'm very new to ExtJS and JS. I was hoping someone could tell me if there is a way to check for repeated rows of the same name when entering a string into a textfield. Is there anything similar to "allowBlank: false" that could be used to check if the string already exists in a row? Or will I simply need to do validation through a series of loops? Please tell me if anything is unclear in my question.
(also my first stack overflow post, so please let me know if there is anything I should have done differently with formatting/tagging)
