正则表达式获取包含起始字符的字符串

Question

I have a string like this

var str="|Text|Facebook|Twitter|";

I am trying to get any one of the word with its preceding pipe sign so something like

|Text or |Facebook or |Twitter

I thought of below two patterns but they didn't work

/|Facebook/g  //returned nothing
/^|Facebook/g // returned "Facebook" but I want "|Facebook"

What should I use to get |Facebook ?

Answer 1

The pipe is special character in a regular expression. A|B matches A or B .

You have to escape the pipe to match | literally.

var str = '|Text|Facebook|Twitter|'
str.match(/\|\w+/g) // => ["|Text", "|Facebook", "|Twitter"]

\\w matches any alphabet, digit, _ .

Answer 2

You should escape | char:

/\|Facebook/g
