Question

我正在尝试创建一个JavaScript程序，它会提示用户输入一系列数字'3-6'，然后输出范围内每个数字的面积，半径和周长。

以下是我的代码到目前为止，我知道它目前无法正常工作，但有几个指针会很棒！

function circum() {
var radius = prompt("Enter the a range of numbers for the circle","");
var radiusanswer = 2 * Math.PI * radius;
var area = radius * radius * Math.PI;
var cube = radius * radius * radius
alert("The circumference is "+radiusanswer)
alert("The area is "+area)
alert("The cube is "+cube)

Answer 1

你很亲密。只需要正确循环所有数字，如下所示

＆＃13;

function circum() {
  var values = prompt("Enter the a range of numbers for the circle", "");
  var range = values.split("-");
  //range[0] = start value
  //range[1] = end value
  for (var i = range[0]; i <= range[1]; i++) {
    var radius = i;

    var radiusanswer = 2 * Math.PI * radius;
    var area = radius * radius * Math.PI;
    var cube = radius * radius * radius
    console.log("The circumference is " + radiusanswer)
    console.log("The area is " + area)
    console.log("The cube is " + cube)
  }

}
circum();

JavaScript周长，直径和多值的半径
