Validating and getting data in a JSON file (All client side, no server) from form fields in extjs. Absolute beginner

Question

Please help me with creating my first extjs form with basic test and combo box fields. I need to validate and accept data from this form on the client side itself in a json file. No server side scripting needed. Also if you provide some good material to learn extjs it will be appreciated!

Answer 1

There are several configs to use in field configuration. eg 'allowBlank, minLength, maxLength,regex,vtype, validator'.

'isValid' method in formPanel will check the validation.

'getValues' methond will get JSON value from the form.

Sencha extjs documents and examples in its official website are very good already.

Please see a simple fiddle example here
