Bookmarlet: Take number from end of URL and put it in a new URL?

I want to create a bookmarklet that will take something like this;
http://www.site1.com/some/random/path/12345
And change it into this, then reload the page;
http://www.site1.com/new/path12345?value=true
Unfortunately I haven't tried much, because I know absolutely nothing about Javascript. I tried to copy a bit of code that does a search and replace on the URL and then tried to add the functions for appending a string, but that didn't work because I had no idea what I was doing or even the proper syntax I was supposed to use. Javascript seems to have about a dozen different ways to alter the current URL and I have no idea when to use each one.

try this,
var urlArray = [];
var myURL= http://www.site1.com/some/random/path/12345;
urlArray = myURL.split('/');
var newURL = "http://www.site1.com/new/"+urlArray[urlArray.length-2]+""+urlArray[urlArray.length-1] +""+"?value=true";
var myPageLink = document.createElement('a');
myPageLink .setAttribute('target', '_blank');
myPageLink .href = newURL;
document.body.appendChild(myPageLink );
myPageLink .click();

Javascript Add Current Domain Name to URL Parameter

How can I retreive a domain name of the current page with javascript, and add it to url parameter like this before redirecting:
http://redirecturl.com?domain={domain}

Quick and easy answer below. However, I little research would have yielded the same without stackoverflow
let url = `http://redirecturl.com?domain=${document.location.hostname}`;
console.log( url );

You can use a simple location.hostname:
const redirectURL = `http://redirecturl.com?domain=${location.hostname}`;
console.log(redirectURL);
ES5:
var redirectURL = "http://redirecturl.com?domain=" + location.hostname;
console.log(redirectURL);
Note: The above return stacksnippets.net because that's where StackOverflow run their snippets (as you will see if you visit the website

jQuery: How to get hotlink from url / hash?

I'm trying to obtain a hotlink from a url a user gets to via a link in an email
Everything after the ? below:
http://localhost:6547/m/intro/inbox/100003120?hotlink=8095cb20284c935d9ff32c0ed61b28f1&codekitCB=400521239.247318
I need to save that hotlink into a variable to POST to a new url, however my code isn't retrieving the hash or hotlink:
jQuery:
$(document).ready(function () {
// MOBILE HACKS
var path = window.location.pathname;
var hash = window.location.hash;
console.log('dashboard.init: path = '+path);
console.log('dashboard.init: hash = '+hash);
Console:
How would you get the hash/hotlink after the ? in the url above?

You can use window.location.search
That will return everything from the ? on, and then you can parse that as needed.

Theres probably a better answer out there, but I've always just used
window.location.href.split('?')
index [1] will be everything after the ?

Read #hash from URL with jQuery

How can I return the hash value of website.com/#something (something) from the URL with jQuery?

window.location.hash
its that simple.
donot use all those methods which consume CPU and effects performance.
If DOM provides something predefined use it first.
To pass value to PHP please do and ajax call to php.
var hash = window.location.hash;
$.ajax({
url: 'someurl.php',
data: {hash: hash},
success: function(){}
})

You can use the location.hash property to grab the hash of the current page:
var hash = window.location.hash;

update
As there is a built in method to get the hash via DOM above answer is not appropriate
var hashTag = window.location.hash
alert(hashTag);
will do the magic.
Old answer
You can do something as below if you have multiple hashes in your url
//var href = location.href; // get the url in real worl scenario
var href = "www.bla.com#myhashtag"; // example url
var split = href.split("#"); // split the string; usually there'll be only one # in an url so there'll be only two parts after the splitting
var afterSplit = "Error parsing url";
if(split[1] != null){
afterSplit = split[1];
}
// If everything went well shows split[1], if not then de default error message is shown
alert(afterSplit);
Here is an example Live Fiddle

You could use this
h=new URL(location).hash.split`&`.find(e=>/hash_name/.test(e)).split`=`[1]

how to remove a part of a url from a url using jquery?

I have a javascript variable
var url = http://www.abc.it/it/security/security.aspx?security=pdfcompare&../securitycomparepdf/default.aspx?SecurityTokenList=blab]2]0]blab$ALL|blab]2]0]blab$ALL|blab]2]0]blab$ALL;
I need to remove the part "../securitycomparepdf/default.aspx?" from it using jquery, so that the variable becomes
http://www.abc.it/it/security/security.aspx?security=pdfcompare&SecurityTokenList=blab]2]0]blab$ALL|blab]2]0]blab$ALL|blab]2]0]blab$ALL;
Can someone please suggest?
Thanks

Made a demo for you: http://jsfiddle.net/B3Uwj/27/ (from #tats_innit)
url = url.replace("../securitycomparepdf/default.aspx?", "");

Use the following JS
var url = "http://www.abc.it/it/security/security.aspx?security=pdfcompare&../securitycomparepdf/default.aspx?SecurityTokenList=blab]2]0]blab$ALL|blab]2]0]blab$ALL|blab]2]0]blab$ALL";
url = url.replace("../securitycomparepdf/default.aspx?","");
​alert(url);​
