I have below url
Input
url1 = https://www.example1.com/xyz/abc/123
I need modified above url and replace only domain to https://www.modifiedexample.com/
Output url2= https://www.modifiedexample.com/xyz/abc/123
This should work in all the browser
How to achieve this in Javasript in simple and efficient way

You can try URL API:
const url = new URL('https://www.example1.com/xyz/abc/123');
url.hostname = 'www.modifiedexample.com';
console.log(url.href); // https://www.modifiedexample.com/xyz/abc/123

How to make a script redirect only once every time an appropriate page loads?

I have the current script to amend a link in the URL bar
(function() {
'use strict';
location.replace(location.href.replace("www.reddit.com", "old.reddit.com"));
})();
I'd want it to check if the URL has the word "old" before running the remainder of the script. How do I do this?

You can check the index of the word old by considering the URL as a normal string.
if(location.href.indexOf('old') > -1) {
// do something
}
It is simple as that.

how to avoid the link to be blocked by browser popup?

http://plnkr.co/edit/m8m2I9dqE2kF1H1nzxJT

Added value, key to CB function args and used that to get at the link value, also added the window name attribute telling open function to open blank window each time:
angular.forEach($scope.links, function(value, key){
$window.open("link.html/?" + value.link, '_blank');
});
$scope.links.link was returning "undefined" in that location.

Encode URL in JavaScript
(22 answers)
Closed 8 years ago.
I want to load another page via Javascript like this
$("#resultarea").load("searchresults.php?searchstring=" + $("#searchbox").val());
in searchresults.php, a single statement
echo $_GET["searchstring"];
what I type in searchbox appears when searchresults.php is loaded except when I add space and another word, no thing appear at all. I heared it can be done by encoding or somewhat, I searched but didn't find a solution.

Try encodeURIComponent:
var encodedValue = encodeURIComponent($("#searchbox").val());
$("#resultarea").load("searchresults.php?searchstring=" + encodedValue);
