Regex Eliminate Vertical Bar/ Pipe Character

Question

Using the following regex with the ExtJS library, the intention is to only allow spaces, dollar signs, underscores, alpha and numeric characters. However, for some reason, the vertical bar/ pipe character is allowed as well. I hope someone can tell me what I am missing here. Am I inadvertently escaping one of the vertical bars?

maskRe:/^[a-z|A-Z|0-9|$|_ ]$/

Thank you kindly for your time!

Answer 1

You don't need the vertical bars inside your character class. Try the following instead:

maskRe:/^[a-zA-Z0-9$_ ]$/
