Ruby - JSON - JavaScript >> Unexpected token \ in JSON

Developers Ruby API
7

:blush: I don’t get it…

Now I created a separate html file too. (test.html beside main.rb)
From the Ruby side I want to send an array (with two string in it). So I’m converting the array to json
Then I’m sending it after the html loaded. (1 sec Timer for now)

What is strange for me it is “arriving” to JavaScript as Array (according to console log in Devtools). Why? I assuming I have to parse back?!
so I can display it without any use of JSON.parse().
What I’m missing here? What is wrong?

# encoding: UTF-8
#dezmo_test/main.rb
module DezmoTest
  extend self
  
  def strange_names
    model = Sketchup.active_model
    layername = model.layers[1].name
    pagename = model.pages.first.name
    display_result_html( [layername, pagename] )
  end
  
  def display_result_html(array)
    p array
    argument_js = array.to_json
    p argument_js
    @dialog = UI::HtmlDialog.new(
      :dialog_title => "Test Dezmo 2022",
      :width => 300,
      :height => 100,
      :left => 100,
      :top => 150,
      :style => UI::HtmlDialog::STYLE_DIALOG
    )
    @dialog.set_file(File.dirname( __FILE__ ) + "/test.html")
    @dialog.show
    UI.start_timer(1, false) {
      @dialog.execute_script("update(#{argument_js});")
    }
  end
end
DezmoTest.strange_names

<!DOCTYPE html>
<html>
  <body>
    <div>Test</div>
    <div id="example"></div>
    <script>
      function update(json){
        console.log(json);
        <!-- var data = JSON.parse(json); -->
        var data = json;
        document.getElementById("example").innerHTML = data.join(' ');
      }
    </script>
  </body>
</html>

Ps (In a realty I’m trying to send an array, containing hashes. The hash values can be the string with the above mentioned characters, or an array with a same structure as the parent… like in this topic )
