jquery 3 0 url indexOf error

Question

I am getting following error from jQuery once it has been updated to v3 0 0   jquery js 9612 Uncaught TypeError  url indexOf is not a function  Any Idea why

User · Answer

Jquery 3 0 has some breaking changes that remove certain methods due to conflicts  Your error is most likely due to one of these changes such as the removal of the  load   event   Read more in the jQuery Core 3 0 Upgrade Guide  To fix this you either need to rewrite the code to be compatible with Jquery 3 0  or else you can use the JQuery Migrate plugin which restores the deprecated and or removed APIs and behaviours

choz answer is the correct way  If you have many usages and want to make sure it works everywhere without changes you can add these small migration-snippet     Migration jQuery from 1 8 to 3 x    jQuery fn load   function  callback        var el     this        el on  load   callback        return el      In this case you got no erros on other nodes e g  on  image like in  Korsmakolnikov answer  const  image      img image   load function         this  doSomething          image doSomethingElseWithTheImage

Update all your code that calls load function like     window  load function               To    window  on  load   function                    jquery js 9612 Uncaught TypeError  url indexOf is not a function   This error message comes from jQuery fn load function   I ve come across the same issue on my application  After some digging  I found this statement in jQuery blog       load   unload  and  error  deprecated since jQuery 1 8  are no more    Use  on   to register listeners    I simply just change how my jQuery objects call the load function like above  And everything works as expected

I came across the same error after updating to the latest version of JQuery  Therefore I updated the jquery file I was working on  as stated in a previous answer  so it said  on  load   instead of  load     This fix isn t very stable and sometimes it didn t work for me  Therefore to fix this issue you should update your code from        load      to       trigger  load      I got this fix from the following source  https   github com stevenwanderski bxslider-4 pull 1024

Better approach may be a polyfill like this   jQuery fn load   function callback     window  on  load   callback       With this you can leave the legacy code untouched   If you use webpack be sure to use script-loader
