[Tut]How to invite all facebook friends to a page/Event in one click [mass invitation on facebook]

Ever had a facebook page / Event where you wanted to invite all your friends in the FB friends list ?
Isnt it boring/time consuming to keep inviting them one after another by clicking invite button ch time?

Well here is a quick solution to this.

For a facebook page:

1) Click on "See All" under Invite friends tab
2) Make sure the list is by "Srch all friends"
3) scroll down to the bottom of the list (this is required so all "invite" buttons are loaded up and hence would be clicked by scrip)
4) Right click and select "Inspect Element"
5) Click on Console tab
6)paste this script:

var inputs = document.getElementsByClassName('uiButton _1sm');
for(var i=0; i<inputs.length;i++) {
inputs[i].click();
}

press enter.
7) wait for 2 minutes until it says invite sent for all.
