remove some special chars from string in javascript

Question

I want to remove two parts of the string in javascript and the string could be in these ways :

/folder/file.scss or /folder/subfolders/_filestwo.scss

what i want is to remove .scss from the end of the file and if file has _ remove the underscore as well.

and the result should be :

/folder/file or /folder/subfolders/filestwo

Answer 1

You can use this pattern: (_)?(\\w+)\\.scss$

 var str1 = '/folder/subfolders/_filestwo.scss'; var str2 = '/folder/file.scss'; var pattern = /(_)?(\\w+)\\.scss$/; console.log(str1.replace(pattern, '$2')); console.log(str2.replace(pattern, '$2'));

Answer 2

只需使用replace功能和正则表达式。

const str = '/folder/file.scss'.replace(/\.scss/g, '').replace(/_/g, '');
