替换 Javascript 中所有出现的字符串

Question

I upload a picture to my Node API, and in my database the path of the picture is like this: public\\uploads\\img\\myImage-1551119543339.png , but I want to return to anyone requesting the imgs like this public/uploads/img/myImage-1551119543339.png . How do a save the path?

Answer 1

All the back-slashes have to be escaped in the original string. Then use split and join on the forward and back slash

 var str="public\\\\uploads\\\\img\\\\myImage-1551119543339.png"; console.log(str.split("\\\\").join('/'))

Answer 2

You can use pattern to replace back slashes.

 var str="public\\\\uploads\\\\img\\\\myImage-1551119543339.png"; console.log(str.replace(/\\\\/g,'/'));
