Question

In my previous version of the application, this code worked fine:

form.find('input').disable();

With new environment (Rails 3.3 and new version of JQuery) this doesn’t work anymore.

The error I’m getting is:

Uncaught TypeError Object[object Object] has not method ‘disable’.

Why do I get this error and how do I solve it?

Answer 1

[].forEach.call( form.elements, function ( el ) { el.disabled = true } )

or in jQuery maybe…

$(document.forms['form_name'].elements).each(function() {
   this.disabled = true;
});
