Question

I have the following line of JQUERY:

 if(html == 'html5' && pastURL == url) {return false;}

This is causing the function its within to show an error:

‘strict warning function does not always return a value’.

Is there a way to alter this so it doesn’t show this error and why is it showing this? Note: don’t have ‘use strict;’ in the code.

thx

Answer 1

All functions must either have no return statement or their last executed line must be a return. So if you’re planning a route that will return false, make sure that the function always returns something no matter how that condition plays out. The easiest way to do this is to put a return statement at the end of the function so that it will always return if it gets there.
