Javascript not working on mobile but works on desktop

Question

This works on a desktop browser, but not on my iOS mobile phone. I tried adding 'touchstart' and looked at this post's solution to check how other's got it to work, but it still isn't working. Any suggestions as to other options? I also tried adding e.preventDefault() - and added e to function(), but that didn't work as well.

I have tried:

 $('body').on('click touchstart', '.myContainer', function() {
     $(this).toggleClass('myContainer-unselected').toggleClass('myContainer-selected');
 });

Edit: It appears there may be something else going on, I changed the code to be as general as possible and it is not firing the event on iOS, but working in my chrome emulator:

$(document).on('click touchstart', 'body', function() {
      alert('hi');
    });

Additional update:

I have added the following code to my script.js file:

$('body').css('display', 'none');

As expected, the screen goes blank on my desktop browser for both local and on heroku, but when I test on mobile, the screen is not blank. It looks like js isn't working properly.

Answer 1

Answer: the reason it wasn't working on iOS Safari is because in my js page I was using ES6, specifically 'let' which is [not supported currently][1]. Changed to ES5 and the issue disappeared.

$('body').on('click', '.dashboard_leftNav_category a', function() {
      var link = $(this).attr('showSection'); //changed from let link
      var show = $('[section="'+link+'"]');
      $('[section]').hide();
      $('body').find(show).fadeIn();
      $('html,body').scrollTop(0);
    });

Answer 2

You have two options:

1. Reset your mobile browser's history because your browser's cache reads the old source.
2. Change the name of your source file in the desktop and refresh your page again.

Answer 3

This should help you. Instead of binding it to the body element, bind the event to the document.

$(document).on('click touchstart', '.myContainer', function() {

      $(this).toggleClass('myContainer-unselected').toggleClass('myContainer-selected');
    });

Also try changing adding the following style to myContainer class

cursor : pointer;
