Is this a valid URL? i.e is it fine to have two '?' separators in the URL?
Note: Due to limitations, I can not add '&' to internal-abhishek-jwt=random_string

It isn't. You have to URL encode the second one if you want to use it as a parameter or use '&' symbol instead if you wanna separate your arguments (which seems to be the case here).
Some further explanation here

The ? still indicates the start of the query string.
Segments of the query string are separated by & characters.
This will be parsed as:
key: audience
value: testingting?internal-abhishek-jwt=random_string

Creating a URL (and not necessarily a parameter list) using jQuery or JavaScript [duplicate]

Encode URL in JavaScript

I am communicating to a REST server which is expecting something like http://example.com/1.0/editor/5/bla/26 along with body parameters of x, y, and z. Or maybe instead of /1.0/editor/5/bla/26, it should be 1.0/editor/5/bla/what about item #26, but of course with what about item #26 escaped.
There are many post describing how to use jQuery.param() to encode parameters, however, that is not my question. How chould the actual url be created using jQuery of JavaScript?
$.ajax({
type:'PUT',
url:'/1.0/editor/'+$('#id').val()+'/bla/'+$('#wha').data('id'),
data:{x:x,y:y,z:z},
success: function (error){}
});

Can you write a javascript RegEx function to replace all spaces with a known character? Or replace it with its HTML equivalent. Then in your backend, just look for that escape character and replace them with the spaces again. It's kind of a work around but depending on your situation it could work.

Is there any way to return the thrown away part of the split operation? [duplicate]

How can I get query string values in JavaScript?

I'm building a basic application which lets the user to share or continue their search status between sessions with # parameters in Javascript (I'm building this as a SPA so GET parameters won't always necessarily work).
In my app I could have a URI like: /items#rarity=rare,common,uncommon&cost=ascending&category=primary
If I wanted to check what state to set the cost filter in my react component, I'd want to extract asecnding and then check the ascending checkbox to set the state on page load.
If I use Javascript's split function combined with regex, I can capture all information on cost by doing:
var hash = window.location.hash;
hash = hash.split(/cost.*&/);
Right now, this will obviously return an array in two parts the first being /items#rarity=rare,common,uncommon& and category=primary as the split function will split on the condition supplied which in my case matches the string from regex.
Is there any way I can capture the extracted string from the split function so I can then parse the cost string?

No way. Oh, there is! Just wrap your regex in the capture group.
var s = '/items#rarity=rare,common,uncommon&cost=ascending&category=primary';
r = s.split(/(cost.*&)/);
console.log(r[0]);
console.log(r[1]); //there is the "thrown" part
console.log(r[2]);

To achieve expected result, use below
var x="/items#rarity=rare,common,uncommon&cost=ascending&category=primary";
console.log(x.split('cost=')[1].substring(0,x.split('cost=')[1].indexOf("&")));

Using ‘&’ in POST variables [duplicate]

ajax post special characters
I am building my own post parameters and passing them via ajax; however, my POST contains an & symbol. How can I post these and escape the special characters so it posts as text only and doesn't split up my value?
Ex:
Thing=lala&lalala
Should be thing = 'lala&lalala' but what I get is thing = 'lala' and ='lalala' where the second key is blank.

You should use encodeURIComponent on your parameters before sending them to the server. It will properly escape everything in your parameters.
Quick example:
var s = 'Thing=' + encodeURIComponent('lala&lalala');
Please note that every value should be encoded separately (so you should not simply use it on the whole query string).

How to validate url?
I have a textbox in a form where user can enter any website url. i want to check that url, whether it is valid or not through regular expression. it will accept only like this "http://www.google.com" or "www.google.co.in".
I have using a expression like
/((http|https|ftp):\/\/(www|WWW)|(www|WWW))\.[A-Za-z]{3}/ .
it is working but when i enter wwww.google.co.in, it says valid.
can any one help me please.

Do a request server side and check for 200 OK. Don't trust the client.

We needed it in our project a couple of weeks ago, and I think we used this one
function isUrl(s) {
var regexp = /(ftp|http|https):\/\/(\w+:{0,1}\w*#)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%#!\-\/]))?/
return regexp.test(s);
}
UPDATE:
I'm still working on it:
(ftp|http|https):\/\/([\-\w]+\.)+\w{2,3}(\/[%\-\w]+(\.\w{2,})?)*(([\w\-\.\?\\/+#&#;`~=%!]*)(\.\w{2,})?)*\/?
