I'm trying to send an array for use in javascript from html with a Ruby's variable like this:
<% @data.each do |d| %>
<input type="hidden" id="name" value= "<%= d.name %>">
<% end %>
"data" is a variable of a model
def index
@data = organizations.all
end
in js i used a variable with id "name"
var nombre = document.getElementById("name").value;
var x = name;
I want that x is an array like:
["Org1","Org2","Org3"]
thanks for everything
You are creating X amount of fields with the same id. That's a problem, the ID should be unique. There is an alternative though, you can use A CLASS!
<% @data.each do |d| %>
<input type="hidden" class="js-names" value= "<%= d.name %>">
<% end %>
Get the list of elements
// Array of elements
var elements = Array.prototype.slice.call(document.getElementsByClassName('js-names'));
var names = elements.map(function(element) { return element.value; });
However, a better approach is definitely using gon
