Acting like a user?

[Robert]

Hi all,

I am wondering if it could be possible that my script acts like the user itself? Well. It is one thing to modify the page. Attach handlers ecc. But what I'd like to do is something like pressing a button (so that the same happens like the user presses the button). So that I need not take care to find out what is done to do it myself.

Something like "GM_click(id)".

Or is there already a way to do this? (The site I want to interact with attaches onclick-handlers and it is not os easy for me to find out what they are really doing. So the easiest way would be to just hit that damned button by my userscript! :))) )


I know it is possible to act like the user, e.g. iMacros does do it:

• https://addons.mozilla.org/de/firefox/addon/imacros-for-firefox/

Well, I do not need iMacro. But just a way to simulate a click.



Regards,
Robert

Ah! Great! Tnx!

This seems to be what I want:

var evt = document.createEvent("MouseEvents");
evt.initEvent("click", true, true);
el.dispatchEvent(evt);

Cheers,
Robert

I have written a more generic function the perfectly fits my needs. So if someone is interessted, feel free to use it.


    // simulate mouse click on element
    function $click( elm, root ) {
        // create mouseclick element

        var evt = document.createEvent( 'MouseEvents' );
        evt.initEvent( 'click', true, true );
       

        // id, class, tag, name or node itself?
        var node;
        if( typeof elm == 'string' ) {
            if( elm[0] == '#' ) node = $( elm, root )
            else                node = $( elm, root )[0];
        } else                  node = elm;
       
        // click node
        node.dispatchEvent( evt );
    }
   
   
    // Get Elements
    function $( q, root, single ) {
        if( root && typeof root == 'string' ) {
            root = $( root, null, true );
            if( !root ) { return null; }
        }

        root = root || document;
        if( q[0] == '#' ) { return root.getElementById(q.substr(1)); }
        else if( q[0] == '/' || ( q[0] == '.' && q[1] == '/' ) ) {
            if( single ) { return document.evaluate(q, root, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue; }
            return document.evaluate(q, root, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null);
        } else  if( q[0] == '.' ) { return root.getElementsByClassName(q.substr(1)); }
        else    if( q[0] == ':' ) { return root.getElementsByName(     q.substr(1)); }
        else    if( q[0] == '<' ) { return root.getElementsByTagName(  q.substr(1)); }

        return root.getElementsByTagName(q);
    }


Regards,

Robert
