Cut substring after last slash?

Question

How can i remove sub string (after last slash) from string in javascript like

c:/Program File/Internet Explorer

to

c:/Program File/

Answer 1

Try lastIndexOf()

var str = "c:/Program File/Internet Explorer";
var newStr = str.substr(0,str.lastIndexOf("/")+1);

document.getElementById("res").innerHTML = newStr;

<div id="res"/>

Answer 2

You may try the below negated char class based regex.

string.replace(/[^\/]*$/, "")

DEMO

• [^\/]* matches any char but not forward slash zero or more times.

• $ asserts that we are at the end of a line.

Answer 3

Check out http://www.regexr.com if you want to test regular expressions. Something like .*/ would match everything up to the slash character.

Answer 4

var str = "c:/Program File/Internet Explorer";
var output = str.slice(0, str.lastIndexOf("/")+1);

Answer 5

You need lastIndexOf and substr

var t = "c:/Program File/Internet Explorer";
t = t.substr(0, t.lastIndexOf("/"));
alert(t);

or you can use the following.

    var removeLastPart = function(url) 
{
        var lastSlashIndex = url.lastIndexOf("/");
        if (lastSlashIndex > url.indexOf("/") + 1)
{
            return url.substr(0, lastSlashIndex);
        } 
else 
{
            return url;
        }
    }

Answer 6

var filePath = "c:/Program File/Internet Explorer";
var displayUptoSpecifiedChar = filePath.lastIndexOf('/') + 1;
console.log(filePath.slice(0, displayUptoSpecifiedChar));
