[Uncaught TypeError: ...mask is not a function] Rails 6.1 setup

[luisampuerov]

Hello,

I'm using your gem on my ruby on rails project. Ruby: 2.6.8, Rails: 6.1.4.1. When I follow the steps in your README I cannot make use of the masks.

Can you please let me know how put the require in the application.js file?: this line: //= require jquery.mask. I think that is a comment one, but if I decomment I get an error, what is the correct format?

When I try to use $('#my_id').mask('999.999.999-99' ) in my javascript I get in the console: Uncaught TypeError: $(...).mask is not a function.

Thanks in advance. Regards

I had the same issue. I was able to solve the problem by removing a duplicate jQuery call I had in my application.html.haml layout file. Then, I included jQuery in my application.js before the jquery.mask require line. Your application.js file would look like this:

//= require rails-ujs
//= require jquery
//= require jquery.mask

Make sure you're not importing any other versions of jquery that could be conflicting and you're good to go :)
