/* the number of times to vote */
var times = 10;

/* The time in milliseconds between each vote.
   Sometimes if the voting is too slow, some errors would occur and less votes
   than specified would be given, so set this interval to something higher if
   that happens. */

/* The index number of the target upvote button in the array of upvote buttons
   present on page. This value must be changed if the target upvote button index
   isn't correct. The following call will return the array:

    document.getElementsByClassName("arrow up login-required access-required");

   Some browsers will show you the location of each element on screen when you
   hover the pointer over the returned array elements in the console.

   The reason the default is set to 25 is because there will usually be 26
   upvote buttons on screen once you load a post with no comments present. The
   post's upvote button in this case should be the last in the array. 25 of
   these buttons are present in chat, so the array will increase once more chat
   messages are loaded. */
var up_button_index = 25;

/* calls the click function at specified intervals */
var intID = setInterval(
    function(){
        /* simulate click on the upvote button */
        document.getElementsByClassName("arrow up login-required access-required")[up_button_index].click();
    },

/* sets the timeout before executing clearInterval, which would stop the
   execution of the clicking function */
