Javascript在某些浏览器上不起作用

Question

I have a javascript like following acting bizarre. Following works fine on my development machine in all three browsers chrome, FF and safari. But when I checked on anyone else machine browsers this value update does not work at all. Does anyone know how would I able to replicate this issue on my local ?

my browser test

Browser name = Chrome Full version = 51.0.2704.103 Major version = 51 navigator.appName = Netscape navigator.userAgent = Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36

jQuery(function(){

  $(document).on("click", "#history span", function() {
    var field_id = $(this).attr('history-id');
    $('#'+field_id).val('some new value');
  })
});

Answer 1

You are missing an ending parenthesis

jQuery(function(){

  $(document).on("click", "#body", function() {
    console.log('sup world!')
  }) // ending paren
});
