A very simple fix that doesn t need to change your code  just add jquery migration script  download here https   github com jquery jquery-migrate   It supplies jquery deprecated but needed functions like  live    browser  etc

The jQuery API documentation lists live   as deprecated as of version 1 7 and removed as of version 1 9  link      version deprecated  1 7  removed  1 9   Furthermore it states      As of jQuery 1 7  the  live   method is deprecated  Use  on   to attach event handlers  Users of older versions of jQuery should use  delegate   in preference to  live

I tend not to use the  on   syntax  if not necessary  For example you can migrate easier like this   old       myButton   live  click   function     new       myButton   click function    Here is a list of valid event handlers  https   api jquery com category forms

You can avoid refactoring your code by including the following JavaScript code   jQuery fn extend       live  function  event  callback           if  this selector                jQuery document  on event  this selector  callback                     return this

If you happen to be using the Ruby on Rails  jQuery gem jquery-rails and for some reason you can t refactor your legacy code  the last version that still supports is 2 1 3 and you can lock it by using the following syntax on your Gemfile   gem  jquery-rails      gt  2 1      2 1 3    then you can use the following command to update   bundle update jquery-rails   I hope that help others facing a similar issue

jQuery  live   has been removed in version 1 9 onwards   That means if you are upgrading from version 1 8 and earlier  you will notice things breaking if you do not follow the migration guide below  You must not simply replace  live   with  on       Read before you start doing a search and replace   For quick hot fixes on a live site  do not just replace the keyword live with on  as the parameters are different    live events  function    should map to    on eventType  selector  function    The  child  selector is very important  If you do not need to use this for any reason  set it to null     Migration Example 1   before       mainmenu a   live  click   function    after  you move the child element  a  to the  on   selector       mainmenu   on  click    a   function      Migration Example 2   before       myButton   live  click   function    after  you move the element   myButton  to the  on   selector  and find the nearest parent element  preferably with an ID        parentElement   on  click     myButton   function    If you do not know what to put as the parent  body always works      body   on  click     myButton   function      See also    jQuery - how to use the    on      method instead of    live       jQuery 1 9 Migration Guide
