Javascript that removes part of string / url query parameters

i use the code below to format some links. Where it can add either a suffix or a prefix to the link. But i have been researching how to remove part of the link.
Example, this link below.
https://www.torrid.com/product/boyfriend-straight-jean---vintage-stretch-medium-wash/14478822.html?cgid=Clothing_Jeans_Straight_Boyfriend#promo_id=210802_Jeans&promo_name=BoyfriendStraight_BoyfriendStraight&promo_creative=2107_FG_Denim_Boyfriend_Straight_277x702&promo_position=Jeans_Slide3&start=1
It has superfluous data, everything after
https://www.torrid.com/product/boyfriend-straight-jean---vintage-stretch-medium-wash/14478822.html
Isn't needed, how can i remove everything past that point when formatting the links, before adding the suffix or prefix. Thanks in advance for any help!
$("#btnGenerateLinks").on("click", function() {
var valNeed = $("#strngtime").val();
// if (valNeed.trim().length) { // For filter blank string
$('input[name="linktype1"]').each(function() {
$(this).val($(this).data("link") + valNeed);
});
$('input[name="linktype2"]').each(function() {
$(this).val(valNeed + $(this).data("link"));
});
// }
});
Update - Yes all query parameters
Update - Going with a simple split for now
var myArr = valNeed.split("?")[0];

you can use the URL constructor API
let url = "https://www.torrid.com/product/boyfriend-straight-jean---vintage-stretch-medium-wash/14478822.html?cgid=Clothing_Jeans_Straight_Boyfriend#promo_id=210802_Jeans&promo_name=BoyfriendStraight_BoyfriendStraight&promo_creative=2107_FG_Denim_Boyfriend_Straight_277x702&promo_position=Jeans_Slide3&start=1"
let instance = new URL(url);
let cleanURL = instance.origin + instance.pathname;
console.log(cleanURL);

Way to get full param value from an URL

I am try to get the data from the param in the URL
http://localhost:8080?test=1&redirectURL=http://localhost:8082/#/abc?param=1
I did
const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
const redirectURL = urlParams.get('redirectURL'); // result: http://localhost:8082
but currently, the URL contain the hash code inside URL so the value return just http://localhost:8082
Is there any way to get full url http://localhost:8082/#/abc?param=1 by getting the param redirectURL
Thank you very much

I hope the following is useful for you.
var url_string = window.location.href;
var url = new URL(url_string);
var paramsTest = url.searchParams.get("test");
var paramsRedirectURL = url.searchParams.get("redirectURL");
console.log(paramsRedirectURL)
console.log(paramsTest)
Example here: https://codepen.io/yasgo/pen/dypWKoM

Maybe this can work for you
var afterHash = window.location.hash;
var beforeHash = window.location.href;
var fullURL = beforeHash ;
if(afterHash != '') // if there is something after hash and hash is exists in url then add the afterHash value in full url
{
var fullURL = beforeHash +"#"+ afterHash ;
}
console.log(fullURL);

I think the biggest issue here is that your redirectURL is not encoded. It should be encoded before it ends up in the URL, because otherwise the params and hashes from the nested URL are going to spill into the parent URL.
I obviously don't know if it would make sense for your project, but I think I would use domurl.
Maybe you should just use encodeURIComponent and possibly decodeURIComponent later, but I wanted to point out that domurl handles encoding and decoding automatically. Just as an example:
var url = new Url("http://localhost:8080?test=1");
url.query.redirectURL = 'http://localhost:8082/#/abc?param=1';
console.log( url.toString() );
// http://localhost:8080/?test=1&redirectURL=http%3A%2F%2Flocalhost%3A8082%2F%23%2Fabc%3Fparam%3D1
So again, what the encoded URL does is it prevents params from spilling from the nested URL to the parent URL and enables you to read redirectURL as a single string that you can then parse again to see/edit whatever params it has. The other important point is that I'm removing the hashtag with replace('/#/','/') in order to read the params from redirectURL:
Here's a slimmer jsfiddle where I'm just extracting the param and leave everything else out.
You'll definitely want to check dev tools consode log instead of the one stackoverflow offers, to make any sense of the objects.
console.log('');
// I'm encoding the redirectURL here, but in the real world it should be encoded before it's added as a parameter.
var url = new Url("http://localhost:8080?test=1&redirectURL="+ encodeURIComponent("http://localhost:8082/#/abc?param=1"));
console.log('url', url);
// So now that I've separated `url.query.redirectURL`, I can read that URL and its params separately...
var redirectUrl = new Url( url.query.redirectURL.replace('/#/', '/') ); // The hashtag is removed
console.log('redirectUrl:', redirectUrl );
console.log('redirectUrl - (param):', redirectUrl.query.param );
console.log('redirectUrl - path:', redirectUrl.path );
// If you need to use redirectURL without modifications you can just take the url param as is:
console.log( 'redirectUrl - no edits:', url.query.redirectURL );
// If you need to edit the params, you could do that and put just back the hashtag
redirectUrl.query.param = 'changed the param';
redirectUrl.path = '/#' + redirectUrl.path
console.log('redirectUrl - edited:', redirectUrl.toString() );

How to get a specific portion of the url using javascript?

var url = window.location.href.toString();
the above line gives me the url of my current page correctly and my url is:
http://localhost/xyzCart/products.php?cat_id=35
However, using javascript how can i get only a portion of the url i.e. from the above url i just want
products.php?cat_id=35
How to accomplish this plz help.I have looked at similar questions in this forum but none were any help for me..

You can sliply use this:
var url = window.location.href.toString();
var newString = url.substr(url.lastIndexOf(".") + 1));
This will result in: php?cat_id=35
Good luck /Zorken17

You can use the location of the final /:
var page = url.substr(url.substr(0, (url + "?").indexOf("?")).lastIndexOf("/") + 1);
(This allows for / in a query string)

You can get your desired result by using javascript split() method.check this link for further detail

https://jsfiddle.net/x06ywtvo/
var urls = [
"http://localhost/xyzCart/products.php?cat_id=35",
"http://localhost/xyzCart/products.php",
"http://www.google.com/xyzCart/products.php?cat_id=37"
];
var target = $('#target');
for(var i=0;i<urls.length;i++){
var index = urls[i].indexOf("xyzCart");
var sub = urls[i].substring(index, urls[i].length);
target.append("<div>" + sub + "</div>");
}

Try the folowing javacript code to get the part you need. It splits up your url by the "/"s and takes the fourth part. This is superior to substr solutions in terms of descriptive clarity.
url.split("/")[4]
Or if url can contain more "/" path parts, then simply take the last split part.
var parts = url.split("/");
console.log( parts[parts.length-1] );

You will get all necessary values in window.location object.
Kindly check on following CodePen Link for proper output.
I have added parameter test=1
Link: http://codepen.io/rajesh_dixit/pen/EVebJe?test=1
Code
(function() {
var url = window.location.pathname.split('/');
var index = 1;
document.write("URL: ");
document.write(window.location.href);
document.write("<br/> Full Path: ");
document.write(window.location.pathname);
document.write("<br/> Last Value:")
// For cases where '/' comes at the end
if(!url[url.length - index])
index++;
document.write(url[url.length-index])
document.write("<br/> Query Parameter: ");
document.write(window.location.search.substring(1));
})()

Removing parameter values of a url in the next page using javascript only

I need to remove the values from the url after the ? in the next page the moment i click from my first page. I tried a lot of coding but could not get to a rite path. Need help.
The strings ex- Name, JobTitle and Date are dynamically generated values for ref.
Below are the links associated with the code:
Required url
file:///C:/Users/varun.singh/Desktop/www%20updated%2027.8.2015%20Old/www/Candidates/newOne.html?
Resultant url:
file:///C:/Users/varun.singh/Desktop/www%20updated%2027.8.2015%20Old/www/Candidates/newOne.html?Name=Name%201&JobTitle=Title%201&Date=Entered%20Date%201
listItem.onclick = function(){
var elementData=listData[this.id];
var stringParameter= "Name=" + elementData.name +"&JobTitle="+elementData.job_title+"&Date="+ elementData.entered_date;
//window.location.href = window.location.href.replace("ListCandidateNew", "newOne") + "?" + stringParameter;
window.location.href="file:///C:/Users/varun.singh/Desktop/www%20updated%2027.8.2015%20Old/www/Candidates/newOne.html?"
+ stringParameter;
}

This should work:
var url = file:///C:/Users/varun.singh/Desktop/www%20updated%2027.8.2015%20Old/www/Candidates/newOne.html?Name=Name%201&JobTitle=Title%201&Date=Entered%20Date%201
var index = url.lastIndexOf("?");
url = url.slice(0, index+1); // index+1 so that "?" is included

Thanks everond for trying and attempting to answer my problem. Well, i have found the solution using window.sessionStorage as i wanted by keeping the string parameter alive to pass the values. Here is the full code:
I have two pages for passing the value from one to another: ListCandidateNew.html and newOne.html
ListCandidateNew.html
listItem.onclick = function()
{
var elementData=listData[this.id];
var stringParameter= "Name=" + elementData.name +"&JobTitle="+elementData.job_title+"&Date="+ elementData.entered_date;
window.sessionStorage['Name'] = elementData.name;
window.sessionStorage['JobTitle'] = elementData.job_title;
window.sessionStorage['Date'] = elementData.entered_date;
**newOne.html**
function LoadCandidateDetail()
{
document.getElementById('Name').innerHTML = window.sessionStorage['Name'];
document.getElementById('JobTitle').innerHTML = window.sessionStorage["JobTitle"];
document.getElementById('Date').innerHTML = window.sessionStorage["Date"];
}

jQuery VAR in IF statement usage

I am sure that this will be a simple solution for someone well versed in jquery.
I am wanting to pass the path name into the if statement so
http://address.com/catalog/product <= catalog then gets passed into the if statment.
if (/\/catalog\//.test(window.location)) {
jQuery('#name-div').hide();
}
so it hides a div if its a child of http://address.com/catalog
var url = location.pathname.split("/")[1];
if (/\/url\//.test(window.location)) {
jQuery('#name-div').hide();
}

As I read your question, what you need is to create a RegExp object from a string since your want to pad with / characters:
var url = location.pathname.split("/")[1],
re = new RegExp('/' + url + '/'); // Create RegExp object from padded string
if (re.test(window.location)) {
jQuery('#name-div').hide();
}

You basically have the answer to your own problem.
$(function(){
var url = window.location.href;
if( /catalog/i.test(url) )
$('#name-div').hide();
});
Unless you have other URLS with catalog in them, there's no reason to dissect the URL any further. Just make sure you select your element after the DOM is ready as I did in my example.

you can do it in many way like:
if( window.location.indexOf(url) !== -1 )
or
if( window.location.search( /url/ig ) )
or
if( window.location.match( /url/ig ).length > 0 )
In this examples you don't even need to use jQuery. It is just normal javascript.
