Question

I want to match whole words using the JS function “index()”

I want to return -1 on this:

var str="hello I am a string";

alert(str.index("str")); //it matches because of STRing, but don't want

Edit: But I strictly want to match “str” only when it appears sorounded by two spaces (but also matching when it is at the beginning/end of a sentence). So \b don’t work for me because I do NOT want to allow "hello I am str. how are you?"to match

Answer 1

Maybe this will work:

(^|\s)str(\s|$)
