Increment integer by 1; every 1 second

javascript, raphael, time

Solution

You can use `setInterval()` for that reason.

var i = 1;

var interval = setInterval( increment, 1000);

function increment(){
    i = i % 360 + 1;
}

edit: the code for your your followup-question:

var interval = setInterval( rotate, 1000);

function rotate(){
      percentArrow.rotate(1,150,150);
}

I'm not entirely sure, how your rotate works, but you may have to store the degrees in a var and increment those var too like in the example above.

Problem

My aim is to create identify a piece of code that increments a number by 1, every 1 second: We shall call our base number indexVariable, I then want to: indexVariable = indexVariable + 1 every 1 second; until my indexVariable has reached 360 - then I wish it to reset to 1 and carry out the loop again. How would this be possible in Javascript? - if it makes a difference I am using the Raphael framework. I have carried out research of JavaScript timing events and the Raphael delay function - but these do not seem to be the answer - can anyone assist?
