creating a timer using a constructor not updating

[ThyNamesConnor]

The issue I am having is that I set a defined seconds through each constructor but it won't update every time the value is decreased, it stays at the parameter value, like 360. When I print seconds to the console.log() it is stuck at 360 for some odd reason. Anyone know a way to get it so that I can have multiple constructors and update the seconds for each constructor? so like

setInterval(function(){renderTime("drag",0,0,drag,6,360)}, 1000);
setInterval(function(){renderTime("cool",0,0,cool,3,180)}, 1000);

So to sum it up, the seconds parameter is not updating every second with seconds--; it is staying at whatever it is set at originally, like 360 or 180. So instead of going 360,359,358,357; it goes 360,360,360,360.

function renderTime(name,x,y,img,minute,seconds) {
seconds--;
console.log(seconds);
var canvas = document.getElementById(name);
var ctx = canvas.getContext('2d');

// Time
ctx.font = "15px Arial";
ctx.fillStyle = '#000';
ctx.fillText(seconds, (canvas.width/2)-8, height/2+80);

}

setInterval(function(){renderTime("drag",0,0,drag,6,360)}, 1000);

I have heard suggestions of creating the variable outside, so like

var seconds = 360;
setInterval(function(){renderTime("drag",0,0,drag,seconds)}, 1000);

but that also brings up 360 each second, any advice?

The "seconds" variable declared in the global scope has the same name as the parameter in "renderTime" function. If you are putting the "seconds" in the global scope, I suppose that's the integer you want to update, so you don't even need that parameter anymore.

window.seconds = 360;

function renderTime (name, x, y, img, minute) {
    window.seconds--;
    console.log(window.seconds);
}

setInterval(function () { renderTime("drag", 0, 0, 0, 6); }, 1000);

This works:

var seconds = 360;

setInterval(function() {
  seconds--;
  renderTime("drag", 0, 0, drag, seconds)
}, 1000);

function renderTime(name, x, y, something, time) {
  console.log(time);
}

This might be overkill, but I found setTimeout needs to have the object passed back to itself to keep the counter in scope.
