javascript - Rails 4 - Coffee script form helper & cross browser compatibility -


im using rails 4 make web app.

i have form in projects view folder, has nested questions. if answer top level question true, further sub questions displayed. if answer false, sub questions related top level question remain hidden.

i have form helper in javascripts folder has hide/show functions form. works fine when use chrome browser. doesn't work @ in safari. in safari, form elements, including supposed hidden @ start, displayed.

how adjust form helper works on browsers?

in js form helper file have:

# source input attrs: {class: 'toggle_div', target: <target_id_or_class>} # toggle_radio attr : {class: 'toggle_div', target: <target_id_or_class>, toggle_reverse: <anything> } #$ -> #  $(document).on 'change', 'input.toggle_div', ()-> #    $($(this).attr('target')).toggle this.checked # #  $(document).on 'change', 'input.toggle_radio', ()-> #    reverse = $(this).attr('toggle_reverse') #    if reverse #      toggle_value = ($(this).val() == 'false') #    else #      toggle_value = ($(this).val() == 'true') #    target = $(this).attr('target') #    $(target).toggle toggle_value    #$ ->     $ ->   settheattributes = (instring)->      if $('#' + instring +  '_sweep_attributes_if_datum').is(':checked')       $('#datarequest').show()     else       $('#datarequest').hide()     $(document).on 'change', '#' + instring +  '_sweep_attributes_if_datum', ()->       if $('#' + instring + '_sweep_attributes_if_datum').is(':checked')         $('#datarequest').show()       else         $('#datarequest').hide()    formlist = document.getelementsbytagname "form"    if(formlist[0].action.includes "/projects")     settheattributes 'project'   if(formlist[0].action.includes "/programs")     settheattributes 'program'   if(formlist[0].action.includes "/proposals")     settheattributes 'proposal'

in application.js file have:

// manifest file that'll compiled application.js, include files // listed below. // // javascript/coffee file within directory, lib/assets/javascripts, vendor/assets/javascripts, // or vendor/assets/javascripts of plugins, if any, can referenced here using relative path. // // it's not advisable add code directly here, if do, it'll appear @ bottom of // compiled file. // // read sprockets readme (https://github.com/sstephenson/sprockets#sprockets-directives) details // supported directives. // //= require jquery //= require jquery_ujs //= require bootstrap //= require bootstrap-switch //= require_tree .
