I wrap the href to URL, and try to remove one component, remove with delete, but component does not disappear. Do you know why?
let url = new URL(window.location.href);
let p = url.searchParams['postId'+$(".selected").length];
delete p;
window.location = url.toString();
I tried this:
const filteredItems = url.searchParams.filter(key => url.searchParams[key] == postID);
let key = filteredItems.keys.first;
url.searchParams.delete(key);
but it says
Uncaught TypeError: url.searchParams.filter is not a function
I tried now this expression, but filter does not work, do you have any idea why?
function togglePost(postID) {
let url = new URL(window.location.href);
const filteredItems = Object.keys(url.searchParams).filter(key =>
url.searchParams[key] == postID
);
let key = filteredItems.keys.first;
The delete operator deletes properties from objects.
You are trying to delete a variable. This fails silently.
To delete something from a URLSearchParams object, use the delete method:
let url = new URL('http://example.com/foo.cgi?a=1&b=2');
console.log(url.toString());
url.searchParams.delete('a');
console.log(url.toString());
