Disabling button after disable_with

问题

In my Rails app, I use the :disable_with helper on a form button.

That form works via ajax. If the object is created successfully, I want to keep that button disabled. So in my create.js.erb file I have: $('#my-button').disabled = true;.

However, it doesn't work (works fine in the console though).

I suspect its interfering with Rails' JS for the disable_with helper. How can I get around that?

回答1:

Use jQuery's .prop() method to set the disabled property of the button. In your case, the code should be

$('#my-button').prop('disabled', true);

To prevent the :disable_with helper from enabling the button again, remove the data-disable-with attribute from the button:

$('#my-button').removeAttr('data-disable-with');
