Finding Plus Sign in Regular Expression
javascript, regex
Solution
Plus is a special character in regular expressions, so to express the character as data you must escape it by prefixing it with `\`.
var reg = /d\+1/;
Problem
``` var string = 'abcd+1'; var pattern = 'd+1' var reg = new RegExp(pattern,''); alert(string.search(reg)); ``` I found out last night that if you try and find a plus sign in a string of text with a Javascript regular expression, it fails. It will not find that pattern, even though it exists in that string. This has to be because of a special character. What's the best way to find a plus sign in a piece of text? Also, what other characters will this fail on?
