Last active August 29, 2015 14:06
// I am confused about how you can use `call` without supplying an object for `this`
// The docs don't indicate that you can:
// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/call
var funny = function (a) { return (a + 3); }
funny(3); // 6
funny.call({},3); // 6
funny.call(3); // NaN // (as expected)

eoinkelly / tinymce_fill_in.rb
Created September 9, 2014 23:53
A capybara helper to fill in text into a TinyMCE editor instance
##
# id must be the id attribute of the editor instance (without the #) e.g.
# <textarea id="foo" ...></textarea>
# would be filled in by calling
# tinymce_fill_in 'foo', 'some stuff'
#
def tinymce_fill_in(id, val)
# wait until the TinyMCE editor instance is ready. This is required for cases
# where the editor is loaded via XHR.
sleep 0.5 until page.evaluate_script("tinyMCE.get('#{id}') !== null")
