Insert javascript call inside <body onLoad=function()> in RAILS

I am n00b at rails. The question is very simple, i want to know how can i make a javascript function call inside body tag on the onLoad event.

I'm asking this because in the views i can't find any body or head tag (It's like they are generated elsewhere).

Thanks

Solution

  • You do not need to modify the body tag to associate a Javascript function with onload. Instead of using the onload attribute on the body, you can assign the function to window.onload inside an external Javascript file.

    There are more advanced ways, using event listeners to do the same thing (trigger the function on page load) which would allow to add several listener functions or trigger functions on DOM ready, a little/some time before page load. Just setting window.onload is the most simple way, and will keep your Javascript unobtrusive.
