I am a Javascript Junkie and wishing to test around some codes.
new RegExp("user=" + un + "[\"'\\s>]", "i")
what will this actually mean?
It was from a site, and it actually works!
I especially don’t get the [\"'\\s>] part.
[and]signify a character class. Basically, it will match one of any characters found within. The backslash\escapes special characters. So you’ll see that the first double-quote is escaped, showing we’re looking for the"char within the value, and not merely using the"within our regular expression to wrap around a value. Then the single-quote'is considered, followed by a backslash (literal – so it too must be escaped\\looks for one backslash). It appears the original was indicating a space, which is\s. And then the greater-than symbol.
