Javascript - 正则表达式取代忽略一些特殊字符

Question

I have a string which can be..

Samsung Blu-Ray Player
Samgung Bluray player
Samsung Blu/Ray player

and I know want to find and replace bluray (later: to give it a certain color). Therefore I want to replace the word using a regex. But no idea about the regex syntax in that case. It should ignore "/" and " " and find the string, case insensitive.

Answer 1

try this :

var str = "Samsung Blu-Ray Player";
var res = str.replace(/(Blu.*?ray)/gi, '<span style="color:red">$1</span>');
console.log(res);

Answer 2

You can replace the string using

str = str.replace(/samsung blu[^\w]?ray player/gi, 'Samsung Blu Ray player')

where

• [^\\w]? - is any nonword character (non alphanumeric)
• The ? makes it optional
• /gi - the flags mean g lobal search and case i nsensitive

Answer 3

/\\bblu\\s*[^\\w]?\\s*ray\\b/gi

\\b the word boundary gives it more conservation from matching blurayfish or so

\\s* makes it white space insensitive so blu - ray will match

[^\\w] matches non-word symbols like - , ? means optional

gi means all matches, case insensitive.
