Question

If for example I have the next event:

document.getElementById('TagSearchInput').onkeyup = function(e)
{
     //Code...
}

Inside the event, there is a condition where I recreate the element (TagSearchInput). How can I refresh the event selector, from within the event?

Answer 1

OK, ignoring any questions about why you’d be recreating the input…

Rather than using an anonymous function try something like this:

function TSIKeyupHandler(e)
{
     //Code...

     // within your condition where you want to re-attach the handler
     document.getElementById('TagSearchInput').onkeyup = TSIKeyupHandler;
}

document.getElementById('TagSearchInput').onkeyup = TSIKeyupHandler;

(Optionally put all of the above inside an immediately-invoked-anonymous-function if you want to keep the TSIKeyupHandler() function out of the global scope.)
