Javascript Regex-单词必须与列表中的任何单词匹配，且顺序不限，且带有单词边界

Question

I have the following regex:

/^(?=.*?\bapple\b)(?=.*?\b(ipad|itunes)\b).*$/i

This matches the word "apple" and one word from the list eg "ipad" or "itunes" in any order.

I now need to extend this to have a word boundary eg apple can be no more than 10 words from any other in the list.

I am using http://refiddle.com/ to build and validate.

Can anyone advise.

这个长的正则表达式应该为您工作：

^(?=.*?((?:ipad|itunes)(?:\W+\w+){0,10}\W+apple\b|\bapple(?:\W+\w+){0,10}\W+(?:ipad|itunes)\b)).+$
