I'm currently trying to retrieve the email from an encoded url similar to this:
https://www.madeupwebsite.com/state=%7B%22application%22:%22SOMETHING%22,%22email%22:%22SOMETHING#madeup.com%22,%22subdomain%22:%22YES%22%7D
I tried decodeURI like this:
const str = 'https://www.madeupwebsite.com/state=%7B%22application%22:%22SOMETHING%22,%22email%22:%22SOMETHING#madeup.com%22,%22subdomain%22:%22YES%22%7D';
const result = decodeURI(str);
but console.log returns this:
"https://www.madeupwebsite.com/state={\"application\":\"SOMETHING\",\"email\":\"SOMETHING#madeup.com\",\"subdomain\":\"YES\"}"
Is there a better way to get the email? Do I have to use regex?
A crude first cut at extracting the email address would be:
JSON.parse(decodeURIComponent(str.substring(str.indexOf('state=') + 6))).email
This yields:
SOMETHING#madeup.com
You have to be more sophisticated, of course, if there are possible multiple parameters besides state in the URL, if you want to do error checking, etc.
Here the solution I came up with:
const decodedUrlObj = decodeURI(str).split("state=").pop();
const formatToJSON = JSON.parse(decodedUrlObj);
console.log("formatToJSON2: ", formatToJSON.username);
// "formatToJSON2: SOMETHING#madeup.com

Before I go on, let me say that I've looked through a number of threads already and can't find an answer that works for me.
Basically, I've built a custom link shortener and I'm using URLSearchParams to pull the URL to be shortened and the custom slug from the URL search query as follows:
var e = window.location.search;
const urlParams = new URLSearchParams(e);
const url = urlParams.get("url");
const slug = urlParams.get("slug");
Where the format for a query is: ?url=https://google.com&slug=customslug
After the parameters are handled, the URL string is treated with trim() to remove any whitespace. The final output is encoded with encodeURIComponent() when the API I'm using (https://short.io) is called.
However, I want to be able to pass URLs with &, like so: ?url=https://google.com/&testing&slug=customslug. My ideal solution would simply treat any & that isn't part of the &slug parameter as a part of the URL contained within the &url parameter. Currently, the & character is ignored if it isn't attached to a valid parameter (url or slug).
I have tried encoding the query input using encodeURIComponent(), but that results in a failure to pick up on either defined parameter. I have also tried splitting the input using split("&slug",1), but that results in an array and I cannot pass arrays to the Short.io API.
Any suggestions?
You should use the URL Encoded ampersand symbol %26.
var e = "?url=https://google.com/%26testing&slug=customslug";
const urlParams = new URLSearchParams(e);
const url = urlParams.get("url");
const slug = urlParams.get("slug");
console.log(url);
console.log(slug);
I solved my issue by building off of #CherryDT's comment about using window.location.hash to get my URL string. Ultimately, I chose to forgo the idea of a slug in the address bar, since it would cause further problems with my script.
While this solution is only applicable for my purposes, I'm detailing the solution because it functions as a workaround for the issue of not being able to encode a passed URL string from the address bar. Might be useful to someone, someday.
var e = window.location.href.replace(window.location.hash, '');
if (e.endsWith("?") === true) {
var url = window.location.hash.substr(1);
if (url === "") {
// Error code
} else {
console.log("A URL to be shortened was provided via hash.");
// Pass url to rest of script
}
}
I'm changing current user's path through a function:
function setSomeValue(someValues) {
var query = '';
for (var i = 0; i < someValues.length; i++) {
query += someValues[i] + ',';
}
if ('URLSearchParams' in window) {
var searchParams = new URLSearchParams(window.location.search);
searchParams.set("paramName", query);
var newRelativePathQuery = window.location.pathname + '?' + searchParams.toString();
history.pushState(null, '', newRelativePathQuery);
}
}
As you can see, I'm adding to user's location new words and want new location to be like this:
www.site.com?paramName=value1,value2,
But browser converts my commas into %2C so I get this:
www.site.com?paramName=value1%2Cvalue2%2C
What should be done to make pushing commas to URL possible?
(copy & paste from several comments)
It might be due to URLSearchParams and its toString method implementation - but we can’t know, because you have not shown us what that actually is. If that is not deliberately encoding the comma, and the browser simply does it automatically - then there’s little you can do about that.
If newRelativePathQuery contains the encoded versions already, maybe they could be replaced back to normal commas. But if history.pushState does it, then “other ways” to create the URL itself won’t help you much.
Since a debug output showed that newRelativePathQuery contains the encoded commas already, you can try and replace them back to commas, and see if that “survives” being pushed to the history then.
It's a little hacky, but here's one solution. Let's say we want to use URL's searchParams.set() to set ids=1,2,3,4 in our query string.
If you just do url.searchParams.set("ids", "1,2,3,4"), the URL will have ids=1%2C2%2C3%2C4. To avoid that encoding, first set ids=LIST_OF_IDS_PLACEHOLDER, get the URL as a string, and then replace LIST_OF_IDS_PLACEHOLDER with 1,2,3,4, like this:
const myList = [1,2,3,4],
url = new URL(document.location.href); // or however you get your URL object
url.searchParams.set("ids", "LIST_OF_IDS_PLACEHOLDER");
const newUrlString = url.toString().replace("LIST_OF_IDS_PLACEHOLDER", ids.join(','));
console.log(newUrlString); // this will include: ids=1,2,3,4
I have a website like below:
localhost:3000/D129/1
D129 is a document name which changes and 1 is section within a document.
Those two values change depends on what user selects.
How do I just extract D129 part from the URL using javascript?
window.location.pathname.match(/\/([a-zA-Z\d]*)/)[1]
^ that should get you the 1st string after the slash
var path = "localhost:3000/D129/1";
alert(path.match(/\/([a-zA-Z\d]*)/)[1])
You can use .split() and [1]:
a = "localhost:3000/D129/1";
a = a.split("/");
alert(a[1]);
This works if your URLs always have the same format. Better to use RegEx. Wanted to answer in simple code. And if you have it with http:// or something, then:
a = "http://localhost:3000/D129/1";
a = a.split("/");
alert(a[3]);
ps: For the RegEx version, see Tuvia's answer.
When placing the "key" variable inside of this string, it displays 'simplelogin%3A5' instead of 'simplelogin:5'. Is there a way to just pass in the latter?
var populateTasks = function(date, key){
$scope.ref = new Firebase("https://myfirebase.firebaseio.com/users/"+key+"/tasks");
};
results in: https://myfirebase.firebaseio.com/users/simplelogin%3A5/tasks
I need: https://myfirebase.firebaseio.com/users/simplelogin:5/tasks
var uri = "//what you need to convert";
var uri_dec = decodeURIComponent(uri);
var res = uri_dec;
Where does the value of key come from? If you get it from a URL, it makes sense that you see %3A.
A : has a special meaning in a URL, so it is escaped. And the URL escape sequence for a : is %3A.
To convert the %3A back to : you simply unescape it like this:
unescape(key)
Or use decodeURIComponent, which in this case accomplishes the same. The best way to decode the value depends on why it was encoded in the first place, hence my initial question.
Have you tried trimming key before concatenating it to the URL?
key = key.trim();
I have one one hidden paramter in form whose value is
custAddress=CustomerAddress.do?fisrtName=scott&lastName=Miles
I want to encode it before sending it and so that characters like & can be replaced with %26 etch
i tried using javascript built-in encodeURI("urlToencode") but does not encode characters like &?
Try this code line,
encodeURIComponent("fisrtName=scott&lastName=Miles");
Use https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/encodeURIComponent
You need to call that on each dynamic part (name and value) of the URL query string. So the question is what is the URI component in custAddress=CustomerAddress.do?fisrtName=scott&lastName=Miles That doesn't really look like a URL because you have the = before the ?
The most sense that I can make is that the full URL is something like
http://myserver/file.do?custAddress=CustomerAddress.do?fisrtName=scott&lastName=Miles
In which case, you should build your URL like
var custAddress = "CustomerAddress.do?fisrtName=scott&lastName=Miles";
var initialPath= "/path/to/file.do?";
var url = initialPath + "custAddress=" + encodeURIComponent(custAddress);
Since you mentioned jQuery, you can use a $.param, looks cleaner and does the encoding for you, and you can give it multiple query parameters at once
var url = initialPath + $.param({
custAdrress: custAddress,
otherParam: "paramVal",
// Both the param name and value need to be encoded and $.param does that for you
"funny Name & Param": "funny & value ="
});
