Question

我正在尝试将随机数添加到数组中，该数组被分配给不断添加数字的函数。

function getMiNumber(number){
    var value = Math.floor(Math.random() * 10) + 1 ;
    value.push(value.value);

    var myArray = someCalc([0]);
    console.log(myArray);
    function showMe(val) {
      var presentMe = document.getElementById('someId');
      presentMe.innerHTML = val;
    }
    showMe(myArray);

            function someCalc(list) {
      var total = 0;
      for(var i = 0; i < list.length; i++){
        total += list[i];
      }
      return total;
    }

}

重新阅读问题并确定需要累计总数，因此本演示将：

生成1到10的随机数。
- 显示该号码。
将该数字添加到数组中。
- 显示该数组。
添加所有数组元素。
- 显示总数。

在此演示var xArray = [23, 8, 90, 7];

中预先确定了数组

＆＃13;

function randomNumber(xArray){
    var value = Math.floor(Math.random() * 10) + 1 ;
    xArray.push(value);
		return xArray;
}
    var xArray = [23, 8, 90, 7];
    var total = calc(randomNumber(xArray));
    console.log(total);
    function output(total) {
      var out1 = document.getElementById('out1');
      out1.value = total;
    }
    

 function calc(list) {
      var total = 0;
      for(var i = 0; i < list.length; i++){
        total += list[i];
      }
      return total;
    }

output(total);

＆＃13;

<output id="out1"></output>

如何将变量的值添加到数组函数？
