[FIXED] How to trim specific characters from end of JavaScript string?

Issue

In javascript, how to I do a right trim?

I have the following:

    var s1 = "this is a test~";

     var s = s1.rtrim('~') 

but was not successful

Solution

Use a RegExp. Don't forget to escape special characters.

s1 = s1.replace(/~+$/, ''); //$ marks the end of a string
                            // ~+$ means: all ~ characters at the end of a string
