I'm checking over my code for uses of == instead of ===, but changing this line:
if(window.location == 'app:/test.html')
To this:
if(window.location === 'app:/test.html')
Results in the block no longer being executed.
What is the correct approach?
The reason for this is because === matches the type as well as the contents.
window.location acts like a string in most cases, but is actually a Location object.
You can change your if to check the href property, which is a string:
if(window.location.href === 'app:/test.html')
Your code will then work as intended!
MDN has a decent article about window.location that's worth a read.
