First of all, the setInterval Method needs a function as first parameter, not "function()". For example:

setInterval(function() {
    console.log("hello");
}, 1000);

You can also use the following syntaxe to declare your function ouside the timer:

function yourfunc() {
    // ...
}
setInterval(yourfunc, 1000);

Also, I think that what you are trying to do is to stop something when your input is clicked or when your page is loaded. If so, the timer is not a good way to do that. You should use an event listener instead.

I hope it helped
