Question

我有一个使用cloudinary，carrierwave和jcrop的rails 4 app。上传按钮和提交工作（使用javascript状态报告）在chrome上但不在firefox或safari上。在firefox控制台中，我得Empty string passed to getElementById().指向elem = document.getElementById( match[2] );注意，有时候在第二次或第三次尝试（点击提交并反复选择图像）之后，它有效。哦，请帮助我互联网世界你唯一的希望。

的application.js

//= require jquery
//= require jquery_ujs
//= require jquery.ui.all
//= require bootstrap
//= require turbolinks
//= require cloudinary
//= require jquery.Jcrop
// require cloudinary/processing // Optional - client side processing (resizing and validation)
//= require autocomplete-rails
//= require_tree .

的Gemfile

...
gem "jquery-rails"
gem 'jquery-ui-rails'
gem "jcrop-rails-v2", "~> 0.9.12.3"
...

Answer 1

这是turbolinks的一个问题。我添加了jquery.turbolinks gem并在javascript的开头放入document.ready。

cloudine与jcrop在chrome上工作但不是firefox或safari
