I was following RailsCasts tutorial JQuery Uploading and I ran into
difficulties.
I would like to be able to select several files, preview only the name of
the files on the website, remove those, which where selected by mistake and
only then upload the neccessary ones in Ruby on Rails.
<br>
I have looked through as well HTML5 and
jQuery-File-Upload<https://github.com/blueimp/jQuery-File-Upload>but I am
pretty new to Ruby on Rails and all this everything. If somebody
gives me a hint what is better and some primitive codes, I will be really
happy
I have got a code but it creates a new Painting and uploads directly, so it
doesnt do what I want.
<%= form_for Painting.new do |f| %>
<%= f.label :image, "Upload paintings:" %>
<%= f.file_field :image, multiple: true, name: "painting[image]" %>
<% end %>
I have found as well another code hier but it doesnt support multiple
selection and I need the only the name of the file to be previewed.
<script type="text/javascript">
function readURL(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
$('#blah').attr('src', e.target.result);
}
reader.readAsDataURL(input.files[0]);
}
}
</script>
<body>
<form id="form1" runat="server">
<input type='file' onchange="readURL(this);" multiple />
<img id="blah" src="#" alt="your image" />
</form>
</body>
I would be really grateful if somebody helps me to deal with it.
