invite all your friends to an event in a single click and that too using your smartphone

You can also invite all your friends to an event in a single click and that too using your smartphone. So let's move onto trick.

Step (1) Open puffin browser and login to your Facebook id.
try going to desktop mode 

Step (2) Open home page of any event, click on invite. After that your friends list will be loaded. I would recommend you to select  only 100-150 friends at once, because puffin can't bear the load of this script, and possibly your page may reload.

Step (3) Now copy the script and paste it in the url box and hit enter. Your friends will be selected. Now click on send invites to send invite in bulk.

javascript:var inputs = document.getElementsByClassName('_1pu2');for(var i=0;i<inputs.length;i++){ inputs[i].click(); }
