Javascript RegEx quote

Question

I\'m having trouble getting this Javascript Regular Expression to work. What i want is to find a character that starts with @\" has any characters in the middle

Answer 1

Try this regular expression:

/@(["'])[^]*?\1/g

An explanation:

• @(["']) matches either @" or @'
• [^]*? matches any arbitrary character ([^] contains all characters in opposite to . that doesn’t contain line-breaks), but in a non-greedy manner
• \1 matches the same character as matches with (["'])

Using the literal RegExp syntax /…/ is more convenient. Note that this doesn’t escape sequences like \" into account.
