I want to get a specific part of a url between the third and fourth slashes of a link on the page.
EDIT: Sorry I don't think I was clear the first time, I meant getting the specific part of the url OF A LINK found on the page.
var getSegment = function (url, index) {
return url.replace(/^https?:\/\//, '').split('/')[index];
}
Usage:
getSegment("http://domain.com/a/b/c/d/e", 4); // "d"
The replace makes sure that the first two slashes after the protocol (http or https) don't count.
Here's a working example of getting a particular path segment.
Code:
var url = "www.test.com/one/two/three?p1=v&p2=v#anc";
var file = url.split('?')[0];
var pathanddomain = file.split('/');
var path = pathanddomain.splice(1, pathanddomain.length-1);
var pathIndexToGet = 2;
document.write(path[pathIndexToGet]);
If you want to do this for the current page, use:
var url = window.location.href;
Also, if your url starts with http(s)://, you will need to remove this.
I'd suggest:
var link = 'http://www.example.com/directory1/directory2/directory3/directory4/index.html';
console.log(link.split('/')[5]);
JS Fiddle demo.
The reason we're using [5] not [4] is because of the two slashes at the beginning of the URL, and because JavaScript arrays are zero-based.
you should elaborate you question and should specify which is your domain, that means on what purpose you are asking that question ??
This may help you:
var urlValue = url.split("/");
Then store urlValue as array.
then pick up third and forth value of the urlvalue on array.

I'm trying to make a bookmarklet that will take part of an URL and redirect to the new URL, but I need to change two parts of the URL that are separate.
The base URL could be:
78.media.tumblr.com/fc87fac5ea0d88e1e22a214d25a169ee/tumblr_p3fjmdiF7f1r9qk1io1_1280.png
I need it to end like this:
s3.amazonaws.com/data.tumblr.com/fc87fac5ea0d88e1e22a214d25a169ee/tumblr_p3fjmdiF7f1r9qk1io1_raw.png
So I need to replace "78.media.tumblr.com" and "1280"
I've tried coming up with something using window.location.assign and location.href.replace but I'm pretty new and couldn't figure it out.
You can do this with regex and window.location.href. This is assuming you are only looking at tumbler though. If you're not, there would be another step in the regex.
// first get the url
var url = window.location.href;
// Use regex to keep only the parts we want and replace the others
var newUrl = url.replace(/.*(\.tumblr.*\_).*(\..*)/, 'http://s3.amazonaws.com/data$1raw$2')
// go to the new page
window.location.href = newUrl;
In general, you can just replace the parts of the string using String.prototype.replace. Depending on how flexible you need the matching to be you can adjust the regexes to be more or less 'matchy'.
const startUrl = '78.media.tumblr.com/fc87fac5ea0d88e1e22a214d25a169ee/tumblr_p3fjmdiF7f1r9qk1io1_1280.png'
const endUrl = 's3.amazonaws.com/data.tumblr.com/fc87fac5ea0d88e1e22a214d25a169ee/tumblr_p3fjmdiF7f1r9qk1io1_raw.png'
const tumblerRegex = /.*\.tumblr\.com/
const numberRegex = /_\d{4}/
function transform (start) {
return start.replace(tumblerRegex, 's3.amazonaws.com/data.tumblr.com').replace(numberRegex, '_raw')
}
console.log(transform(startUrl) == endUrl)
I need the whole parameter list as such , not one by one
var Url = "http://localhost/Home/Admin?param1=1¶m2=2$param3=3";
I want to get the whole parameter list from the url.
var params = "param1=1¶m2=2¶m3=3";
var Url = "http://localhost/Home/Admin?param1=1¶m2=2$param3=3";
var urlArray = url.split("?");
var params=urlArray[1];
You can see Using split() example of Mozilla Developer Network for more insight on using the split function.
Thanks for the support, I use this one for my need
var params = window.location.href.split('?')[1];
I have for example, https://www.example.com/test1/something?asd=1. Of this example URL I need to grab everything up until and included /test1/. So I would set var url = https://www.example.com/test1. The problem is that test1 is dynamic so I can not have any hard coded values.
How can I do this?
One way is to use a combination of split() and join():
var url = "https://www.example.com/test1/something?asd=1";
var result = url.split("/",4).join("/");
Here's a JSFiddle of it in action:
http://jsfiddle.net/msm3jsvw/
I have a url
/stars/planets/usa/en/universe/planet_stars.html
I need to get the planets_stars.html. How do I get that last portion alone?
Neither jQuery nor regex necessary here:
url.split('/').pop();
Using pure javascript:
var url = "/stars/planets/usa/en/universe/planet_stars.html";
var page = url.substring(url.lastIndexOf("/")+1);
Edit: second parameter of substring method optional and not required in this case. So, I removed it.
or just JavaScript.
var parts = url.split('/');
var lastpart = parts[parts.length -1];
You can use pop() as jmar said too, just remember that removes it from the array when you do it, so you can't use the pop method twice on the same array and get the same value.
How would I go about trimming/stripping the URL down to the page name...
So: http://www.BurtReynoldsMustache.com/whatever/whoever/apage.html
Would become: apage.html
Any ideas?
you do not need jquery:
var url = window.location.href;
var page = url.substring(url.lastIndexOf('/') + 1);
Edit: a good point of the possible query string:
// it might be from browser & / anywhere else
var url = window.location.href;
url = url.split('#').pop().split('?').pop();
var page = url.substring(url.lastIndexOf('/') + 1);
ok, if the location object is available, use pathname gives better result as show below, however, a url can be a string or something directly from text field or span/label. So above solution should have its place.
With location and any link (<a>) elements on the page, you get a load of properties that give you specific parts of the URL: protocol, host, port, pathname, search and hash.
You should always use these properties to extract parts of the URL in preference to hacking about with href and probably getting it wrong for corner cases. For example, every solution posted here so far will fail if a ?query or #fragment is present. The answers from Rob and digitalFresh attempt to cope with them, but will still fail if a / character is present in the query string or fragment (which is valid).
Instead, simply:
var pagename= location.pathname.split('/').pop();
Most of the solutions here are not taking advantage of the window.location object. The location object has this wonderful thing called pathname which returns just the path, no query string, host, protocol, hash, etc.
var mypage = window.location.pathname.split("/").pop();
You could do something like this:
document.location.href.split('/').pop();
Edit: you probably want to get rid of the query string if there is one also:
document.location.href.split('/').pop().split('?').shift();
Edit 2: this will also ignore an anchor in the url if there is one
document.location.href.split('/').pop().split(/\?|#/).shift();
This should also exclude query and hash values.
var path = location.href;
path = path.substring(path.lastIndexOf("/") + 1);
path = path.split("?")[0].split("#")[0];
console.debug(path);
Haven't tested so compeltely guessed, but I'm sure something like this will do :-)
var url = 'http://www.BurtReynoldsMustache.com/whatever/whoever/apage.html';
var page = url.split('/');
alert(page[page.length-1]);
EDIT Tested under jsfiddle and it was wrong, the above code should now work :-)
