Weird one but is it possible to make Link work without the text helloworld.com being in the source?
Long story but I have function breaking helloworld because it matches it and I remember back to my AOL days where you could "encode" a url to look completely different text but it still took you to that url? Note I dont mean encoding the ? or = etc - but the actual text of domain name... have I completely imagined this?

To what end? If you want to totally prevent users from figuring out the URL before they click the link, no that's impossible. If instead you just want to prevent that URL from being picked up by scrapers that don't run JavaScript, then yes that is entirely possible.
What I would do in that case is add a data attribute to the link with an encoded version of the URL.
Link
Then in your JavaScript, decode. Untested jQuery example to get you started:
$('a[data-href-rot13]').each(function (index, el) {
$(this).attr('href', rot13($(this).attr('data-href-rot13')));
});
Of course, you might want a different algorithm than rot13. You could use AES and base-64 encode the output for use in the tag. In case you do want rot13, see this post: https://stackoverflow.com/a/15747894/362536
You can url encode your URL:
(here just on the 'l' character)
Hello World !
It's not an encryption, but a simple encoding. Url cannot use all characters inside of them, so special chars can be passed with the form %XX where XX is the hexadecimal representation of the char.
You browser will decode it, before using it. This coding is normally seen after the url for params and path (ie: url.com/this%20space), but it is also available inside the domain name.
You can encode an url like that with this short javascript:
var encodeUrl = function(url) {
return url.split('//')[0] + '//'
+ url.split('//')[1]
.replace(/[a-z ]/gi, function(c) {
return '%' + c.charCodeAt(0).toString(16);
});
}
url = 'http://www.helloworld.com/';
encodedUrl = encodeUrl(url)
document.body.innerHTML = 'Raw url: <pre>' + url + '</pre>EncodedUrl: <pre>' + encodedUrl + '</pre>Result: TEST';

I am trying to change url with pushstate in java script and my url doesn't have any space or bad character for url but java script encode it and add some character in it.
my code is:
name= name.trim();
const nextState = { additionalInformation: name };
window.history.pushState(nextState, "", my_domain()+"/brands/" + name);
my url is:
http://localhost/brands/Brilliance
but it show as:
http://localhost/brands/Brilliance%E2%80%8C
The '%E2%80%8C' at the end of your URL is an invisible Unicode/ASCII character that you are likely copying when you have pasted in the URL, or maybe a package is causing it. In either case, here are two ways you can solve this:
You can paste your link into a hex editor and remove the invisible character manually before copy-pasting back into your code editor.
You can use this javascript solution to remove the characters:
function remove_non_ascii(str) {
if ((str===null) || (str===''))
return false;
else
str = str.toString();
return str.replace(/[^\x20-\x7E]/g, '');
}
console.log(remove_non_ascii('äÄçÇéÉêHello-WorldöÖÐþúÚ'));
The provided code has no reason to not work, but I have a suspicion that in fact name is malformed. If I get the %E2%80%8C suffix in the URL and run it trough decodeURI, I get an empty string. However, if I manually convert it to the string \xe2\x80\x8c, I get the following: â\x80\x8C. This most probably means corrupted data.
Change your URL using encodeURIComponent
const nextState = encodeURIComponent('http://localhost/brands/Brilliance');
history.pushState({}, '', nextState);
This will change your url and the URL will not have any spaces and bad characters
Having an issue with the following code, it displays the full URL of the current page, (eg, example.com/dir1) however I am looking to display the sub directories only (eg, /dir1/). Also having an issue where it does not display spaces properly, spaces show in html encoding %20. I have very little programming experience and any help would be greatly appreciated.
<p3><script>document.write(location.href);</script></p3>
EDITworking on the following script, however am having trouble implementing it
<script>str.replace("%20", " ")</script>any thoughts?
EDIT - answer which suited my needs, many thanks to brettc
var url = location.href;
url = url.split("examle.com").pop();
url = decodeURIComponent(url);
document.write(url);
This may not be the best way, but a way none the less.
You could just split the string by the ”/“ and take the last occurrence.
Also, decodeURIComponent() will decode the %20 to a space, as found here.
<script>
var url = location.href;// get url, put in url variable
url = url.split("/").pop();// get last element separated by “/“
url = decodeURIComponent(url);// remove any %20
alert(url);
</script>
Note: this will alert everything past the last “/“.
I'm doing some work with a chrome extension that needs to use the google chrome results URLs, which are redirects, and convert those to ordinary URLs for use.
Examples:
me Googling Google: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwi6w8WR4ZzSAhUZHGMKHRntAv0QFggaMAA&url=https%3A%2F%2Fwww.google.com%2F&usg=AFQjCNFePWT_Lkni-D9ikX7wC3eYuDMQYQ&sig2=gPD7xuE6nstkxWFhSh2QLQ&bvm=bv.147448319,d.cGw
What I want: https://www.google.com
I've tried using string.split().pop(), but that just used EVERYTHING after the inputted text. For a basic example, I want a way to reliably turn testHItestBYE into HIBYE. What would be the best way to do this?
Redirect URLs seem to have target URL in the url parameter, so we can split the string using '&url=' as delimiter, pop the last element, split it using '&' as the delimiter, get the first element. It is URL-encoded, so we'll have to decode it.
var findURL = function findURL(url){
return decodeURIComponent(url.split('&url=').pop().split('&')[0]);
}
//example call
result = findURL( 'https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwi6w8WR4ZzSAhUZHGMKHRntAv0QFggaMAA&url=https%3A%2F%2Fwww.google.com%2F&usg=AFQjCNFePWT_Lkni-D9ikX7wC3eYuDMQYQ&sig2=gPD7xuE6nstkxWFhSh2QLQ&bvm=bv.147448319,d.cGw' );
console.log(result);
There are other ways to do it.
$.ajax({
url: "/api/v1/cases/annotations/" + case_id + "/" + encodeURIComponent(current_plink),
I am using encodeURIComponent to escape slash. But it does not work for me. This code convert "slash" to "%2F" but apache does not recognize it.
My php part like this :
$app->get('/cases/annotations/:case_id/:prep_name', 'authenticatePathologist', function($case_id, $prep_name) use ($app) {
If i try to send parameter which include slash, it returns page not found.
But if i try to send parameter which does not include slash, it returns OK.
You should encode it twice with encodeURIComponent, i.e. encodeURIComponent(encodeURIComponent(current_plink)). If you encode it only once, the server decodes it, and it's the same as not encoding it at all.
you should follow
AllowEncodedSlashes Directive
I too had a similar issue with url like:
?filters=new:item:text
where it required to escape the colons. for that I tried replacing it to format
?filters/:items/:text but that couldn't work as the Chrome was NOT encoding the '/' value.
Tried the js [escape() method][1] and it worked like charm.
let url = 'https://dev.test.something?filters=';
let filterString = 'new:item:text';
url = url + escape(filterString);
Output:
https://dev.test.something?filters=new%3Aitem%3Atext
Hope this finds helpful!!
I have a Spring-MVC application with Freemarker as the view component.
In my templates, several links are generated which point back to my application and which include URL parameters containing a hash key (#).
Example:
parameter: Q#106368 11
URL generated by Freemarker with encoded param: testurl.html?key=Q%23106368%2011
I use JavaScript to redirect to this URL (reason: I use JS to manage loading of 2 frames at the same time).
The redirect method is simple:
function redir(url) {
window.location.href = url;
}
The JS call generated by Freemarker looks like
test
My problem is that the browser / Javascript converts back the URL encoded parameter, thinks there is a # and cuts off there.
When I use window.location.href='http://...' directly it works. Only when using the method parameter it seems to be magically URL decoded and then the redirect fails because the URL gets cut off at the #.
Is there an easy way to transmit the parameter correctly?
I am aware that I could replace the #, e.g. with $$$hash$$$, in the template and do the replacement on the server side again. But there are so many places I would have to change...
As Marc B commented, it is necessary to URL encode again. The method would be encodeURI(). However, this method does not encode the # sign. For my specific use case, I have to replace the # sign with %23 after the encoding.
The redirect JS method finally looks like:
function redir(url) {
url = encodeURI(url);
url = url.replace(/#/g, '%23');
window.location.href = url;
}
Comparing escape(), encodeURI(), and encodeURIComponent()
encodeURIComponent/decodeURIComponent is more thorough than just encodeURI, it will decode/encode '#' and event '/'
What browser are you using? I'm trying FireFox 5 and it doesn't convert %23 back into # in my testing. When you mouse over the link or copy the link location, what does that have? Are you sure whatever is outputting the link isn't doing the conversion?
Update
This isn't ideal, but it seems like it solves the problem:
<a onclick="url = 'http://localhost:8080/testappp/testurl.html?key=Q%23106368%2011';" href="javascript:redir(url);">test</a>
It seems like the href attribute is decoded. When I mouse over it I seen the # instead of the %23.
