Question

I want to create a bookmarklet that sets the page to be editable, that is, to run this code:

javascript:document.body.contentEditable=true; 

When I made a bookmark of that, I could see that the page becomes editable very briefly and then the whole thing is replaced with the word ‘true’.

Answer 1

Bookmarklets have to evaluate to void for the browser stay on the same page. Just end it with a void(0):

javascript:document.body.contentEditable=true;void(0);
