Re: [Skunkworks] Tiny script for WhatsApp Web on Chrome

18 Nov 2016


      I've no experience with chrome extensions, if it's easy to do then you can
give it a try. The script is fairly basic and the only required lib is
jQuery.

Hi John,
Why can't you make it a chrome/firefox/edge extension? It's will be much
easier for devs & non-devs. I can help with this.
Kind regards,
Joseph.

Hi,
Not sure if I'm alone here, but I use WhatsApp web on chrome like all
day, and one thing that really bothers me is accidentally sending a message
to the wrong group. We've all seen the consequences online, for some it's
just a funny mistake, for others it's disastrous.
So I wrote a tiny little script that you can inject into chrome that
prompts a confirmation before you send a message to any group. You'll need
to install a chrome extension
<https://chrome.google.com/webstore/detail/custom-javascript-for-web/poakhlngfciodnhlhhgnaaelnpjljija>
that can inject javascript into the web page, and enable jQuery 2.xxx.
Here's the script, hope someone else finds it useful. Improvements &
suggestions, are welcome. It's very brittle since I rely on class names to
find out what's going on in the page, but at least for now it works.
Note: Once you "Save" the script in the extension, reload the page,
noticed that jQuery fails to load 1st time round, after that it's ok.
//----------------Script start
jQuery.noConflict();
jQuery(document).keydown(function(e) {
    var groupIconCount = jQuery('.pane-chat .icon-group-default').length;
    if(groupIconCount > 0 ){
        var groupName = jQuery('.pane-chat .chat-title
.emojitext:first').text();
if(e.which == 13) {
            if(confirm('Are you sure you want to send that message to '
+ groupName + '?')==false){
                 e.preventDefault();
                 e.stopPropagation();
                 jQuery('.input-placeholder .input').text('');
                 return false;
            }
        }
    }
    else{
        console.log('Not in group, confirm aborted!');
    }
});
jQuery(document).click(function(){
    var groupName = jQuery('.pane-chat .chat-title
.emojitext:first').text();
    jQuery('.input-emoji .input-placeholder').html('Type a message to
<b style="color:' + getRandomColor() + '">' + groupName.toUpperCase() +
'</b>.');
})
function getRandomColor() {
    var letters = '0123456789ABCDEF';
    var color = '#';
    for (var i = 0; i < 6; i++ ) {
        color += letters[Math.floor(Math.random() * 16)];
    }
    return color;
}
//--------------------Script End

John K.
