Exercise #1: Euler's Problem - Sum of Multiples

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000.

Html

<div class="result" id="func">
	<button onclick="euler1()">click</button>
</div>

Javascript

var euler1 = function() {
    var total = 0;
    for (var i = 0; i < 1000; i++){
        if (i % 3 === 0 || i % 5 === 0) {
        	total += i; 
        }
    }
    document.getElementById("func").innerHTML=total;
};

Result
