Open url in same tab AND 'document.write' after

问题

Half of my question was answered with this.

I need to open another url (or replace location/href/src, whatever) in the current tab and after that inject HTML via document.write (or innerHTML, whatever) into the new page.

The code will be used in a Chrome bookmarklet which will open an enhanced version of the new page.

Here is what I got so far:

javascript: window.open('https://stackoverflow.com/','_self').document.write('Page Booster 3000');

Any thoughts are appreciated.

P.S 1: the code partially works if the url parameter is empty (''), but it remains in the old page domain.

P.S 2: any way of achieving this in plain vanilla JS?

回答1:

I've reading some threads and just found that it is neither a document.write issue nor a cross origin limitation.

I will take what gion_13 wrote in one of the reference threads:

"it won't work. new page = new script. can't run a script in a different page that it's declared in."

References:

Javascript bookmarklet go to URL and execute

Load a page and apply javascript in a single bookmark

tampermonkey script stops working if I change the page
