数组从参数值推送数据[重复]

Question

这是我到目前为止所做的

function setcanvas(ID,Count,Count1,Count2,Count3,Count4,Count5,Count6,Count7,Count8,Count9,Count10){
  var ctx = document.getElementById(ID).getContext('2d');
  ctx.canvas.width = 350;
  ctx.canvas.height = 300;
  var arr=[];
  var y=1;
  var str = "Count";
  while(y <= Count){
    var str2 = str + y;
    arr.push(str2);
    y++;
  }
}

我希望我的数组的值是参数上的值，但它不是。相反，我看到的值是 Count1、Count2、Count3 ...。有人可以向我解释一下吗？有什么方法可以实现这个目标吗？

找到解决方案

感谢下面的评论。我想出了这个解决方案。

  function setcanvas(ID,Count,Count1,Count2,Count3,Count4,Count5,Count6,Count7,Count8,Count9,Count10){
  var ctx = document.getElementById(ID).getContext('2d');
  ctx.canvas.width = 350;
  ctx.canvas.height = 300;
  var myBarChart = new Chart(ctx, {
    type: 'horizontalBar',
    data: {
        labels: ["Analytics 1", "Analytics 2", "Analytics 3", "Analytics 4", "Analytics 5"],
        datasets: [{
            label: "Count",
            data: getCountByArguments(Count1, Count2, Count3, Count4, Count5, Count6, Count7, Count8, Count9, Count10),
            backgroundColor: setUpBC(Count)
        }]
    },
    options: {}
  });

  function getCountByArguments(){
    var arr = [];
    var i=0; 
    while(i < Count) {
        arr.push(arguments[i]);
        i++;
    }
    return arr;
  }

 }

添加函数 getCountByArguments

使用可以使用arguments 对象来获取参数，类似于下面的代码

function setcanvas(ID,Count,Count1,Count2,Count3,Count4,Count5,Count6,Count7,Count8,Count9,Count10){

  var arr=[];
for (var i=2; i < arguments.length; i++) {
        arr.push(arguments[i])
    }
    console.log(arr);
}

setcanvas(1,10,"a","b","c","d","e","f","g","h","i","j");

setcanvas(1,3,"a","b","c");
