javascript - Replace single backslash "" with double backslashes "\"

Question

I have string with file path. I want to replace all single backslashes ("") with double backslashes ("").

   var replaceableString = "c:asdflkjklsdffjkl";
   var part = /@""/g;
   var filePath = replaceableString .replace(part, /@""/);
   console.log(filePath);

Console showed me it.

   c:asdlkjklsdfjkl

I found something like this, unfortunately it didn't work. Replacing with \

Answer 1

var replaceableString = "c:asdflkjklsdffjkl";
alert(replaceableString);

This will alert you c:asdlkjklsdfjkl because '' is an escape character which will not be considered.

To have a backslash in your string , you should do something like this..

var replaceableString = "c:\asd\flkj\klsd\ffjkl";
alert(replaceableString);

This will alert you c:asdflkjklsdffjkl
