Learning to extract and validate data from form fields using ExtJS, without relying on server-side code, and storing it in a JSON file. Just starting out in the

I am seeking assistance in setting up my inaugural extjs form featuring fundamental text and combo box input fields. My goal is to validate and capture data from this form solely on the client side, saving it to a json file without requiring server side scripting. Any recommendations for valuable resources to familiarize myself with extjs would be greatly valued!

Answer №1

If you're interested in learning how to load a form from a Json file, I have provided a sample example on my fiddle page which you can find here.

This is a great opportunity for those who are eager to learn.

  1. To get started, make sure to check out the Sencha Docs at ()
  2. Visit for more resources.
  3. You can also explore tutorials at https://www.tutorialspoint.com/extjs/.

The tutorials mentioned above mainly cover the basics of ExtJS. To truly master it, delve into the documentation.

Answer №2

Field configuration offers various options to use, such as 'allowBlank, minLength, maxLength, regex, vtype, validator'.

The 'isValid' method within the formPanel can be used to validate the input fields.

By utilizing the 'getValues' method, you can retrieve JSON values from the form easily.

Extjs Sencha provides excellent documentation and examples on their official website.
