Question

I have this expression to check wether if a key exists in a url :

new RegExp('/'+x+'/ig')

(removed the irrelevant code)

Thing is, it isn’t working. I suppose I have to use delimiters (start and end) to work, since the url has many other things, but not sure how to do it.

Any thoughts?

Answer 1

When you use new Regex(), you have to pass the flags as a second parameter

new RegExp(x, 'ig')

Note that you don’t need the literal delimiters when you create a RegExp this way
