I need to get the width of an element into a ruby variable.
I have tried using various methods to call a javascript function that’s
in the prototype library called getDemensions. I’m just not sure how to
perform the call.
document.GetElementById(id).offsetWidth works fine with and onClick
event, but I need to get the width value at various time during the page
load. I also tried the remote_function and javascript_tag methods, to no
avail.
How do I call javascript without an event in rails?
Any suggessions?
