如何从只有 JS 的路径中删除文件名？

Question

i was looking everywhere to a way of remove only the filename of a path with JS, but I only find information of how to remove the path, and keep the filename. I have this path:

C:\Users\usuario\Desktop\CyT\Proyectos\AlmPas\2022-06-17\luis@gmail.com\1234567890.zip

But then, i only need the path:

C:\Users\usuario\Desktop\CyT\Proyectos\AlmPas\2022-06-17\luis@gmail.com\

If i use the next code, i get the filename only, but how can i get the path without the filename?

soloArchivo = ruta_archivos.replace(/^.*[\\\/]/, '')

Answer 1

Extract with this regular expression:

 const str = String.raw`C:\Users\usuario\Desktop\CyT\Proyectos\AlmPas\2022-06-17\luis@gmail.com\1234567890.zip` const regex = /^.*[\\\/]/; const match = str.match(regex); if (match) { console.log(match[0]) } else { console.log("Sorry, there is no match.") }

Results : C:\Users\usuario\Desktop\CyT\Proyectos\AlmPas\2022-06-17\luis@gmail.com\
