How to search/replace text being copied before sending to clipboard using Javascript/jQuery? -

-

i managed add text what's being copied using code in this answer(the second option). however, when change string concatenation , add call replace, error "replace not function".

copytext = window.getselection().replace(/some pattern/, 'replace value'); // fails

the "selection" object seems complex , can't find text inside it. call tostring on that's not option because i'm copying html contenteditable div , need preserve formatting.

i'm trying because have relative links in div's content , they're being converted absolute links in copied text reason. happens when accessing my demo rawgit. locally, works normally.

any ideas on how accomplish this?

update

here's jsfiddle current setup: https://jsfiddle.net/8kx8v8pb/

you need cast string (getselection() returns selection object). either append "" or cast string .tostring() before executing .replace()

so in case, code should this:

copytext = (window.getselection() + "").replace(/some pattern/, 'replace value');

or

copytext = (window.getselection().tostring()).replace(/some pattern/, 'replace value');
