Javascript: remove trailing spaces only

rated 0 times [ 169] [ 7] / answers: 1 / hits: 15755 / 8 Years ago, thu, june 16, 2016, 12:00:00

Can anyone help me on how to remove trailing spaces in JavaScript.
I want to keep the leading spaces as is and only remove trailing spaces.

EG: ' test ' becomes ' test'.
Seems like pretty simple but I can't figure it out.

PS: I am pretty sure I can't be the first one to ask this but I can't find an answer in SO. Also, I am looking for JavaScript solution. I am not using jQuery.

Use String#replace with regex /s+$/ and replacing text as empty string.

string.replace(/s+$/, '')

console.log(

  '-----' + '    test    '.replace(/s+$/, '') + '-----'

)
