javascript - jquery 3 document ready is blocking turbolinks from executing -


i using jquery 1.12.4 far , ok, had : 

$(document).ready ->      console.log "document ready yaay!"      start = ->          alert "hello world!!!"      document.addeventlistener('turbolinks:load', start)

i upgraded rails 5.1 yesterday , decided add , upgrade jquery (yep still need it) installed jquery 3 using yarn, same code above doesn't executed, @ least turbolinks part (the console.log executed every time document loaded "start" method not)

i removed $(document).ready -> , code start working expected !!!

to make sure removed jquery 3 , installed jquery 1.12 , worked! $(document).ready ->

why happening ?

make sure add //= require jquery application.js file.

in command line, run yarn install jquery lower case

here application.js file 1 of project using jquery through yarn.

//= require rails-ujs //= require turbolinks //= require jquery //= require_tree .

edit: if want console.log , alert fire @ every page change. can write javascript this.

$(document).on('turbolinks:load', function() {   console.log('test');   alert("hello world!!!"); });
