Selected Value after onChange

[glauni]

Hi there,

im trying to keep the value that is selected in my dropdown after an onchange event.

Im using RoR (Rails) to get the data, which you'll see below

<%= select_tag 'c', options_for_select(@c.pluck(:name, :id)), include_blank: '', class: 'select' %>

selectize = $(".select").selectize({
    create: true,
    allowEmptyOption: false,
    delimiter: ',',
    plugins: ['restore_on_backspace'],
    onChange: function(value){
      location.href = window.location.protocol + '//' + window.location.host + '/c/' + value
    }
  });

Obviously, without the location.href my selected value is set and also persists, however i'd like to have it persist even when im changing the url.

I tried to set the value after my reload happened, didnt quite work. (Tried it with setValue(value, silent), setTextboxValue(str) as well as fiddleling with some of the events (initialize, load, clear))
I didnt seem to find any other question regarding this case - would be nice if someone has an Idea how to achieve this.

€: updated my question with more information.

How are you setting the initial value? After you change the url you will need to have a method to update the selected value after the page reloads

I have edited my question again to possibly show a little better what I have already tried. Im sure im missing something
