How to select all friends at once to invite friends on Facebook:-

Hi,,guyzz while I am surfing the net I come to knew a fine and best trick for facebook user which was give by aumkar thakur,,,
                                        I think it that its an a huge problem for all of us as that I am having quit good no. of  friends on Facebook and It to hard to maintain all :p Whenever I create a Facebook event Its to hard to invite all my friends, It just waste my lot of time. 
                                                                                                                 Then one day I shared this problem with my good Friend Deepak . Then he told me that "You can select all friends at once to invite friends on Facebook" with the help of JavaScript. So When  i started learning JavaScript, i came to know that we can easily select all check boxes by making a small JavaScript command line. Today I am sharing this trick with you all.

How to invite all freinds:-

• Open Google Chrome 
• Now open any event etc. where you can invite your friends.
• Now scroll down until all your friends appears in the box.

• Press CTRL+SHIFT+J 
• A window will open in bottom of the browser
• Paste this line of JavaScript code in the console

javascript:elms=document.getElementsByName("checkableitems[]");for (i=0;i<elms.length;i++){if (elms[i].type="checkbox" )elms[i].click()}; 

Note-After pasting click enter, now wait for a minute and and when all friends are selected click on send, if you have large number of friends it may take about 1 - 2 minutes for successfully sending the invites .
