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?
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
It kinda looks like you're mixing regexp literals and strings.
One way to write a regexp is like this:
var myExp = new RegExp('[a-z]*')
It matches any number of letters from a-z, any number of times. Another way to do the same thing would be like this:
var myExp = /[a-z]*/
or even
var myExp = /[a-z*]/ig
where ig means "ignore case" and "global".
So, stick to one way of writing it. Don't mix strings and literals.
Edit:
If you want to use the first syntax, but also ignore case and make the match global, pass the string 'ig' as a second argument to the RegExp-constructor (new RegExp('[a-z]*', 'ig'))
