I tried to iterate through the array and print the sum. But the output am getting is elements of the array.
<p id="ans"></p>
<script>
var text = "the mean is ";
function mean() {
var sum = 0;
var input = document.getElementsByName("values");
for (var i = 0; i < input.length; i++) {
sum += input[i].value;
text = text + sum;
}
document.getElementById("ans").innerHTML = text;
}
</script>
Parse the string values into integers and then sum it. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/parseInt This is because in javascript if you adding a number to a string it will be casted to a string. For example:
0 + '1' + '2' // 012
But with parse int:
0 + parseInt('1') + parseInt('2') // 3
Or you can cast to int with a simple plus also:
0 + (+'1') + (+'2') // 3
