javascript - Trim specific character from a string

Question

What's the JavaScript equivalent to this C# Method:

var x = "|f|oo||"; 
var y = x.Trim('|'); //  "f|oo"

C# trims the selected character only at the beginning and end of the string!

Answer 1

One line is enough:

var x = '|f|oo||';
var y = x.replace(/^|+||+$/g, '');
document.write(x + '<br />' + y);
