Question

I gave it a college try, but I’m stumped. I’m trying to find consecutive slashes within a string. The rest of the regex works great, but the last part I can’t quite get.

Here’s what I have:

val.match( /^[\/]|[~"#%&*:<>?\\{|}]|[\/|.]$/ ) 

and finding this thread, I decided to update my code to no avail:
RegEx to find two or more consecutive chars

val.match( /^[\/]|[\/]{2,}|[~"#%&*:<>?\\{|}]|[\/|.]$/ ) 

What do I need to get this thing going?

So, I need this regex to look for many characters. That would explain the first code sample that I provided:

val.match( /^[\/]|[~"#%&*:<>?\\{|}]|[\/|.]$/ ) 

What I need it to also do, is look in the string for a double whack. Yes, I’m well aware of indexOf and other string manipulation techniques, but I labeled it regex because it needs to be. Let me know if you need more info…

Answer 1

Here’s the answer.

val.match( /^[\/|_]|[~"#%&*:<>?\\{|}]|[\/]{2,}|[\/|.]$/ )

Not sure why the other version doesn’t work, but maybe someone could shed some light onto the matter.

Tests:

1. _text – Failed leading underscore
2. /text – Falied leading whack
3. text~moreText – Failed contains invalid character: ~”#%&*:<>?\{|}
4. text//text – Failed double whack
5. text/ – Failed trailing whack
6. text. – Failed trailing period

Not sure why the code below wasn’t working, but moved the double whack test and it works now:

val.match( /^[\/|_]|[\/]{2,}|[~"#%&*:<>?\\{|}]|[\/|.]$/ )
