Question

I use regex to match any string contains certain word (e.g: ‘dark’)

     if (features[i].attributes.color.match(new RegExp(dark, "ig")) ) )
..
..

How can I modify it to match any string contains ‘dark; but NOT contains ‘blue’ ?
I tried:

if(
features[i].attributes.color.match(new RegExp(dark, "ig")) ) && !features[i].attributes.color.match(new RegExp(blue, "ig")) )
}
..
..

with no luck

Answer 1

if(features[i].attributes.color.indexOf("dark") != -1 && features[i].attributes.color.indexOf("blue") == -1){
// found dark, didn't find blue
}
