How to simulate click and paste link on form input using javascript?

Question

JavaScript

I want to simulate clicking and pasting a link in an input form using javascript.

(There are sites that, when inserting a link to a video, show detailed information, but through the code it simply inserts, detailed information does not pop up).

On the VKontakte site, if you try to add a video from youtube (i.e. when you insert the youtube link into the form for adding a VKontakte video with the mouse, additional information comes out, and if through javascript, then it simply inserts the youtube link, but additional information does not come out)


If with the mouse insert a link:

If through the code:



I tried to do this with the jQuery library:

$("input").val("111"); 
jQuery("body *").blur();
jQuery("body *").focus();

etc. focus, but does not respond. What else can be added so that everything is the same as if done through the mouse?

Answer 1

Depends on what exactly the form developers are checking, in each case.
If they check isTrusted , then you can't fake it at all, unless you modify your browser with a file.

Answer 2

I do not quite understand the task
of clicking, you can do this $(element).trigger('click');
