Remove everything after last backslash

Question

var t = "\some\route\here"

I need "\some\route" from it.

Thank you.

Answer 1

You need lastIndexOf and substr...

var t = "\\some\\route\\here"; t = t.substr(0, t.lastIndexOf("\\")); alert(t); 

Also, you need to double up \ chars in strings as they are used for escaping special characters.

Update Since this is regularly proving useful for others, here's a snippet example...

// the original string  var t = "\\some\\route\\here";    // remove everything after the last backslash  var afterWith = t.substr(0, t.lastIndexOf("\\") + 1);    // remove everything after & including the last backslash  var afterWithout = t.substr(0, t.lastIndexOf("\\"));    // show the results  console.log("before            : " + t);  console.log("after (with \\)    : " + afterWith);  console.log("after (without \\) : " + afterWithout);

Answer 2

As stated in @Archer's answer, you need to double up on the backslashes. I suggest using regex replace to get the string you want:

var t = "\\some\\route\\here"; t = t.replace(/\\[^\\]+$/,""); alert(t);
