I have a string that looks like this "/testpress/about/" and I need to convert it to "about".
I can easily remove testpress by doing the following:
var slug=relativeUrl.replace("testpress", "");
I have not had luck with removing the slashes:
noslash = slug.replace(/\\/g, '');
How can I go about this so I am left with the desired slug?
It is because you are using the wrong slashes
noslash = slug.replace(/\//g, '');
Look here:
> "/testpress/about/".replace(/\//g, '')
'testpressabout'
I like the RegEx method. That way you can see all the path components.
var path = "/testpress/about/";
var pathComponents = path.match(/([^\/]+)/g);
// to get current page... (last element)
var currentPageSlug = pathComponents[pathComponents.length - 1];
This will work regardless of the trailing slash. The good thing is that no matter how deep the URL structure is, you can always get the path components by referencing them as pathComponents[0], pathComponents[1], pathComponents[2], etc ...
With the RegEx method you also do not need to define 'testpress' in the replace/match/split function. That way it makes your code more reusable.
Why don't you use
"testpress/about/".split('\/')
which will yield
["testpress", "about", ""]
and there you have it: second element of the array.
You could also use a regular expression to match everything after the slash but before the end of the string, like so:
var text = "testpress/about";
var slug = text.match(/([^\/]+)\/?$/)[1];
//slug -> "about"
I like #Michael Coxon's answer but the accepted solution doesn't take into account query parameters or things like '.html'. You could try the following:
getSlugFromUrl = function(url) {
var urlComponents = url.match(/([^\/]+)/g),
uri = urlComponents[urlComponents.length - 1];
uri = uri.split(/[\.\?\&]/g);
if (uri.length) {
slug = uri[0];
}
return slug;
};
This should return only the slug and not anything afterwards.

I have a url like the following
http://localhost:8000/test/
What is the tidiest way of getting test from this using plain javascript/jQuery?
You can do it easily like following using split() method.
var str = 'http://localhost:8000/test/';
var arr = str.split('/');
console.log(arr[arr.length-2])
The section of the URL you are referring to is called the path, in Javascript this can be accessed by reading the contents of the location.pathname property.
You can then use a regular expression to access only the final directory name (between the last two slashes).
Don't you guys like regex? I think it is simpler.
s = 'http://localhost:8000/test/';
var content = s.match(/\/([^/]+)\/[^/]*$/)[1];
JS split() function does magic with location.pathname .
var str = location.pathname.split('/');
var requiredString = str[str.length -2];
requiredString will contain required string, you may console log it by console.log(requiredString) or use it anywhere else in the program.
let arr = link.split('/');
let fileName = arr[arr.length - 2] + "/" + arr[arr.length - 1];
It will return all data after second last /.
You can use :
window.location.pathname
returns the path and filename of the current page.
with the split() function
To learn more about window.location in w3 School :
https://www.w3schools.com/js/js_window_location.asp
//window.location.pathname return /test
var path=window.location.pathname.split("/");
var page=path[0]; //return test`
How do I get the last segment of a url? I have the following script which displays the full url of the anchor tag clicked:
$(".tag_name_goes_here").live('click', function(event)
{
event.preventDefault();
alert($(this).attr("href"));
});
If the url is
http://mywebsite/folder/file
how do I only get it to display the "file" part of the url in the alert box?
You can also use the lastIndexOf() function to locate the last occurrence of the / character in your URL, then the substring() function to return the substring starting from that location:
console.log(this.href.substring(this.href.lastIndexOf('/') + 1));
That way, you'll avoid creating an array containing all your URL segments, as split() does.
var parts = 'http://mywebsite/folder/file'.split('/');
var lastSegment = parts.pop() || parts.pop(); // handle potential trailing slash
console.log(lastSegment);
window.location.pathname.split("/").pop()
The other answers may work if the path is simple, consisting only of simple path elements. But when it contains query params as well, they break.
Better use URL object for this instead to get a more robust solution. It is a parsed interpretation of the present URL:
Input:
const href = 'https://stackoverflow.com/boo?q=foo&s=bar'
const segments = new URL(href).pathname.split('/');
const last = segments.pop() || segments.pop(); // Handle potential trailing slash
console.log(last);
Output: 'boo'
This works for all common browsers. Only our dying IE doesn't support that (and won't). For IE there is a polyfills available, though (if you care at all).
Just another solution with regex.
var href = location.href;
console.log(href.match(/([^\/]*)\/*$/)[1]);
Javascript has the function split associated to string object that can help you:
const url = "http://mywebsite/folder/file";
const array = url.split('/');
const lastsegment = array[array.length-1];
Shortest way how to get URL Last Segment with split(), filter() and pop()
function getLastUrlSegment(url) {
return new URL(url).pathname.split('/').filter(Boolean).pop();
}
console.log(getLastUrlSegment(window.location.href));
console.log(getLastUrlSegment('https://x.com/boo'));
console.log(getLastUrlSegment('https://x.com/boo/'));
console.log(getLastUrlSegment('https://x.com/boo?q=foo&s=bar=aaa'));
console.log(getLastUrlSegment('https://x.com/boo?q=foo#this'));
console.log(getLastUrlSegment('https://x.com/last segment with spaces'));
Works for me.
Or you could use a regular expression:
alert(href.replace(/.*\//, ''));
var urlChunks = 'mywebsite/folder/file'.split('/');
alert(urlChunks[urlChunks.length - 1]);
Returns the last segment, regardless of trailing slashes:
var val = 'http://mywebsite/folder/file//'.split('/').filter(Boolean).pop();
console.log(val);
I know, it is too late, but for others:
I highly recommended use PURL jquery plugin. Motivation for PURL is that url can be segmented by '#' too (example: angular.js links), i.e. url could looks like
http://test.com/#/about/us/
or
http://test.com/#sky=blue&grass=green
And with PURL you can easy decide (segment/fsegment) which segment you want to get.
For "classic" last segment you could write:
var url = $.url('http://test.com/dir/index.html?key=value');
var lastSegment = url.segment().pop(); // index.html
Get the Last Segment using RegEx
str.replace(/.*\/(\w+)\/?$/, '$1');
$1 means using the capturing group. using in RegEx (\w+) create the first group then the whole string replace with the capture group.
let str = 'http://mywebsite/folder/file';
let lastSegment = str.replace(/.*\/(\w+)\/?$/, '$1');
console.log(lastSegment);
Also,
var url = $(this).attr("href");
var part = url.substring(url.lastIndexOf('/') + 1);
Building on Frédéric's answer using only javascript:
var url = document.URL
window.alert(url.substr(url.lastIndexOf('/') + 1));
If you aren't worried about generating the extra elements using the split then filter could handle the issue you mention of the trailing slash (Assuming you have browser support for filter).
url.split('/').filter(function (s) { return !!s }).pop()
window.alert(this.pathname.substr(this.pathname.lastIndexOf('/') + 1));
Use the native pathname property because it's simplest and has already been parsed and resolved by the browser. $(this).attr("href") can return values like ../.. which would not give you the correct result.
If you need to keep the search and hash (e.g. foo?bar#baz from http://quux.com/path/to/foo?bar#baz) use this:
window.alert(this.pathname.substr(this.pathname.lastIndexOf('/') + 1) + this.search + this.hash);
To get the last segment of your current window:
window.location.href.substr(window.location.href.lastIndexOf('/') +1)
you can first remove if there is / at the end and then get last part of url
let locationLastPart = window.location.pathname
if (locationLastPart.substring(locationLastPart.length-1) == "/") {
locationLastPart = locationLastPart.substring(0, locationLastPart.length-1);
}
locationLastPart = locationLastPart.substr(locationLastPart.lastIndexOf('/') + 1);
var pathname = window.location.pathname; // Returns path only
var url = window.location.href; // Returns full URL
Copied from this answer
// Store original location in loc like: http://test.com/one/ (ending slash)
var loc = location.href;
// If the last char is a slash trim it, otherwise return the original loc
loc = loc.lastIndexOf('/') == (loc.length -1) ? loc.substring(0,loc.length-1) : loc.substring(0,loc.lastIndexOf('/'));
var targetValue = loc.substring(loc.lastIndexOf('/') + 1);
targetValue = one
If your url looks like:
http://test.com/one/
or
http://test.com/one
or
http://test.com/one/index.htm
Then loc ends up looking like:
http://test.com/one
Now, since you want the last item, run the next step to load the value (targetValue) you originally wanted.
var targetValue = loc.substr(loc.lastIndexOf('/') + 1);
// Store original location in loc like: http://test.com/one/ (ending slash)
let loc = "http://test.com/one/index.htm";
console.log("starting loc value = " + loc);
// If the last char is a slash trim it, otherwise return the original loc
loc = loc.lastIndexOf('/') == (loc.length -1) ? loc.substring(0,loc.length-1) : loc.substring(0,loc.lastIndexOf('/'));
let targetValue = loc.substring(loc.lastIndexOf('/') + 1);
console.log("targetValue = " + targetValue);
console.log("loc = " + loc);
Updated raddevus answer :
var loc = window.location.href;
loc = loc.lastIndexOf('/') == loc.length - 1 ? loc.substr(0, loc.length - 1) : loc.substr(0, loc.length + 1);
var targetValue = loc.substr(loc.lastIndexOf('/') + 1);
Prints last path of url as string :
test.com/path-name = path-name
test.com/path-name/ = path-name
I am using regex and split:
var last_path = location.href.match(/./(.[\w])/)[1].split("#")[0].split("?")[0]
In the end it will ignore # ? & / ending urls, which happens a lot. Example:
https://cardsrealm.com/profile/cardsRealm -> Returns cardsRealm
https://cardsrealm.com/profile/cardsRealm#hello -> Returns cardsRealm
https://cardsrealm.com/profile/cardsRealm?hello -> Returns cardsRealm
https://cardsrealm.com/profile/cardsRealm/ -> Returns cardsRealm
I don't really know if regex is the right way to solve this issue as it can really affect efficiency of your code, but the below regex will help you fetch the last segment and it will still give you the last segment even if the URL is followed by an empty /. The regex that I came up with is:
[^\/]+[\/]?$
I know it is old but if you want to get this from an URL you could simply use:
document.location.pathname.substring(document.location.pathname.lastIndexOf('/.') + 1);
document.location.pathname gets the pathname from the current URL.
lastIndexOf get the index of the last occurrence of the following Regex, in our case is /.. The dot means any character, thus, it will not count if the / is the last character on the URL.
substring will cut the string between two indexes.
if the url is http://localhost/madukaonline/shop.php?shop=79
console.log(location.search); will bring ?shop=79
so the simplest way is to use location.search
you can lookup for more info here
and here
You can do this with simple paths (w/0) querystrings etc.
Granted probably overly complex and probably not performant, but I wanted to use reduce for the fun of it.
"/foo/bar/"
.split(path.sep)
.filter(x => x !== "")
.reduce((_, part, i, arr) => {
if (i == arr.length - 1) return part;
}, "");
Split the string on path separators.
Filter out empty string path parts (this could happen with trailing slash in path).
Reduce the array of path parts to the last one.
Adding up to the great Sebastian Barth answer.
if href is a variable that you are parsing, new URL will throw a TypeError so to be in the safe side you should try - catch
try{
const segments = new URL(href).pathname.split('/');
const last = segments.pop() || segments.pop(); // Handle potential trailing slash
console.log(last);
}catch (error){
//Uups, href wasn't a valid URL (empty string or malformed URL)
console.log('TypeError ->',error);
}
I believe it's safer to remove the tail slash('/') before doing substring. Because I got an empty string in my scenario.
window.alert((window.location.pathname).replace(/\/$/, "").substr((window.location.pathname.replace(/\/$/, "")).lastIndexOf('/') + 1));
Bestway to get URL Last Segment Remove (-) and (/) also
jQuery(document).ready(function(){
var path = window.location.pathname;
var parts = path.split('/');
var lastSegment = parts.pop() || parts.pop(); // handle potential trailing slash
lastSegment = lastSegment.replace('-',' ').replace('-',' ');
jQuery('.archive .filters').before('<div class="product_heading"><h3>Best '+lastSegment+' Deals </h3></div>');
});
A way to avoid query params
const urlString = "https://stackoverflow.com/last-segment?param=123"
const url = new URL(urlString);
url.search = '';
const lastSegment = url.pathname.split('/').pop();
console.log(lastSegment)
I have the following link:
sitename.com/Default.aspx?PageID=13078494
I want to grab the following: "PageID=13078494". This is what I have so far:
var url = "sitename.com/Default.aspx?PageID=13078494";
urlmatch = url.match([PageID=13078494]);
urlmatch[0];
Is this the proper expression for what I'm trying to do?
Your regex and its syntax are wrong.
A better way would be to not use a regex at all. Use .split() instead:
var urlmatch = url.split('?')[1];
Here's the fiddle: http://jsfiddle.net/qpXNU/
var myregexp = /[?&]PageID=(\d+)/i;
var match = myregexp.exec(url);
if (match != null) {
//This is if your match it successful
result = match[1];
} else {
//This is if url doesn't match
result = "";
}
This one will work regardless of where PageID is. It will match
sitename.com/Default.aspx?PageID=13078494
anything.org/Default.aspx?PageID=13078494
sitename.com/Default.aspx?foo=bar&PageID=13078494
sitename.com/Default.html?foo=bar&PageID=13078494&bar=foo
Default.html?foo=bar&PageID=13078494&bar=foo
Importantly, it WON'T match
sitename.com/Default.aspx?NotThePageID=13078494
Or without the checking, simply
url.match(/[?&]PageID=(\d+)/i)[1], but I'd advice against that unless your SURE it will always match.
Try the following regex, which will extract the PageID and place it in the first match group:
var url = "sitename.com/Default.aspx?PageID=13078494";
urlmatch = url.match(/PageID=(\d+)/);
alert(urlmatch[1]); // 13078494
If you are matching specific value, then it's fine, otherwise use below to match any number of digits in pageID:
/PageID=\d+/
as:
var url = "sitename.com/Default.aspx?PageID=13078494";
var urlmatch = url.match(/PageID=\d+/);
alert(urlmatch[0]);
or to match 8 exact digits in pageID, use:
/PageID=\d{8}/
as:
var url = "sitename.com/Default.aspx?PageID=13078494";
var urlmatch = url.match(/PageID=\d{8}/);
alert(urlmatch[0]);
When it comes to handling URLs, the browser is pretty good.
You should convert your string to an actual URL like so:
var toURL = function (href) {
var a = document.createElement('a');
a.href = href;
return a;
};
Now use the browser's built-in parsing capabilities:
var url = toURL('sitename.com/Default.aspx?PageID=13078494');
alert(url.search);
Let's say I have a URL:
http://something.com/somethingheretoo
and I want to get what's after the 3rd instance of /?
something like the equivalent of indexOf() which lets me input which instance of the backslash I want.
If you know it starts with http:// or https://, just skip past that part with this one-liner:
var content = aURL.substring(aURL.indexOf('/', 8));
This gives you more flexibility if there are multiple slashes in that segment you want.
let s = 'http://something.com/somethingheretoo';
parts = s.split('/');
parts.splice(0, 2);
return parts.join('/');
Try something like the following function, which will return the index of the nth occurrence of the search string s, or -1 if there are n-1 or fewer matches.
String.prototype.nthIndexOf = function(s, n) {
var i = -1;
while(n-- > 0 && -1 != (i = this.indexOf(s, i+1)));
return i;
}
var str = "some string to test";
alert(str.nthIndexOf("t", 3)); // 15
alert(str.nthIndexOf("t", 7)); // -1
alert(str.nthIndexOf("z", 4)); // -1
var sub = str.substr(str.nthIndexOf("t",3)); // "test"
Of course if you don't want to add the function to String.prototype you can have it as a stand-alone function by adding another parameter to pass in the string you want to search in.
If you want to stick to indexOf:
var string = "http://something/sth1/sth2/sth3/"
var lastIndex = string.indexOf("/", lastIndex);
lastIndex = string.indexOf("/", lastIndex);
lastIndex = string.indexOf("/", lastIndex);
string = string.substr(lastIndex);
If you want to get the path of that given URL, you can also use a RE:
string = string.match(/\/\/[^\/]+\/(.+)?/)[1];
This RE searches for "//", accepts anything between "//" and the next "/", and returns an object. This object has several properties. propery [1] contains the substring after the third /.
Another approach is to use the Javascript "split" function:
var strWord = "me/you/something";
var splittedWord = strWord.split("/");
splittedWord[0] would return "me"
splittedWord[1] would return "you"
splittedWord[2] would return "something"
It sounds like you want the pathname. If you're in a browser, keep an a element handy...
var _a = document.createElement('a');
...and let it do the parsing for you.
_a.href = "http://something.com/somethingheretoo";
alert( _a.pathname.slice(1) ); // somethingheretoo
DEMO: http://jsfiddle.net/2qT9c/
In your case, you could use the lastIndexOf() method to get the 3rd forward slash.
Here's a very cool way of handling this:
How can I remove all characters up to and including the 3rd slash in a string?
My preference of the proposed solutions is
var url = "http://blablab/test/page.php";
alert(url.split("/")[3]);
//-> "test"
Inestead of using indexOf it is possible to do this this way:
const url = 'http://something.com/somethingheretoo';
const content = new URL(url).pathname.slice(1);
Is there a way to remove everything after a certain character or just choose everything up to that character? I'm getting the value from an href and up to the "?", and it's always going to be a different amount of characters.
Like this
/Controller/Action?id=11112&value=4444
I want the href to be /Controller/Action only, so I want to remove everything after the "?".
I'm using this now:
$('.Delete').click(function (e) {
e.preventDefault();
var id = $(this).parents('tr:first').attr('id');
var url = $(this).attr('href');
console.log(url);
}
You can also use the split() function. This seems to be the easiest one that comes to my mind :).
url.split('?')[0]
jsFiddle Demo
One advantage is this method will work even if there is no ? in the string - it will return the whole string.
var s = '/Controller/Action?id=11112&value=4444';
s = s.substring(0, s.indexOf('?'));
document.write(s);
Sample here
I should also mention that native string functions are much faster than regular expressions, which should only really be used when necessary (this isn't one of those cases).
Updated code to account for no '?':
var s = '/Controller/Action';
var n = s.indexOf('?');
s = s.substring(0, n != -1 ? n : s.length);
document.write(s);
Sample here
var href = "/Controller/Action?id=11112&value=4444";
href = href.replace(/\?.*/,'');
href ; //# => /Controller/Action
This will work if it finds a '?' and if it doesn't
May be very late party :p
You can use a back reference $'
$' - Inserts the portion of the string that follows the matched substring.
let str = "/Controller/Action?id=11112&value=4444"
let output = str.replace(/\?.*/g,"$'")
console.log(output)
It works for me very nicely:
var x = '/Controller/Action?id=11112&value=4444';
var remove_after= x.indexOf('?');
var result = x.substring(0, remove_after);
alert(result);
If you also want to keep "?" and just remove everything after that particular character, you can do:
var str = "/Controller/Action?id=11112&value=4444",
stripped = str.substring(0, str.indexOf('?') + '?'.length);
// output: /Controller/Action?
You can also use the split() method which, to me, is the easiest method for achieving this goal.
For example:
let dummyString ="Hello Javascript: This is dummy string"
dummyString = dummyString.split(':')[0]
console.log(dummyString)
// Returns "Hello Javascript"
Source: https://thispointer.com/javascript-remove-everything-after-a-certain-character/
if you add some json syringified objects, then you need to trim the spaces too... so i add the trim() too.
let x = "/Controller/Action?id=11112&value=4444";
let result = x.trim().substring(0, x.trim().indexOf('?'));
Worked for me:
var first = regexLabelOut.replace(/,.*/g, "");
It can easly be done using JavaScript for reference see link
JS String
EDIT
it can easly done as. ;)
var url="/Controller/Action?id=11112&value=4444 ";
var parameter_Start_index=url.indexOf('?');
var action_URL = url.substring(0, parameter_Start_index);
alert('action_URL : '+action_URL);
