1. Sum of odd numbers within 100

1.1 Operation process and ideas

This is to input the specified value inside the function, and calculate the sum of odd numbers through the loop of the for statement. and output the code. The specific thought process is as follows:

1.2 Code snippet

The code is as follows (example):

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<title></title>
		<script>
		var n=prompt("请输入数值：");	
        var sum=0;
        for (var i=1;i<=n;i++){
            if (i%2!=0){
                sum += i;
            }
        }
        document.write(sum);
    </script>
	</head>
	<body>
	</body>
</html>

1.3 JavaScript statement code

The code is as follows (example):

<script>
		var n=prompt("请输入数值：");	
        var sum=0;
        for (var i=1;i<=n;i++){
            if (i%2!=0){
                sum += i;
            }
        }
        document.write(sum);
    </script>

1.4 Run screenshot

The running results are as follows (example):
