javascript - 如何根据数组的长度添加变量？

Question

我有一个值范围从A到Z的数组，我想将其转换为依赖于输入数据的变量，例如:

输入数据

362,232,113，这成为一个长度为3个单位的数组。

所以我想根据输入数组的长度分配变量的名称，但是在执行代码时，它很好地分配了数组索引，但是相同的索引执行输入数组的长度并且不分配变量如我所愿。事实上，在执行时会发生这种情况:

(3) 326显示矩阵被正确划分但相同的索引被执行了3次，总之我想要的是执行如下:

“A = 326”“B = 232”“C = 113”

提前感谢您的帮助

var asignLetter = ["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","Z","X","Y","Z"];

matrix =[326,232,113];

function divide(){
    xyz = matrix.split(",");
    console.log(matrix);
    for(var i = 0;i < xyz.length; i++){
        window[assignLetter[i]] = xyz[i];
        console.log(A); //(2) 326

    }
}

您有一个拼写错误 assignLetter 而不是 asignLetter (两个 s )，并且您需要传递一个 string到你的函数让它工作:

var assignLetter = ["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","Z","X","Y","Z"];

divide("326,232,113")// input data

function divide(matrix){
    xyz = matrix.split(",");
    for(var i = 0;i < xyz.length; i++){
        window[assignLetter[i]] = xyz[i];
    }
}

console.log({A,B,C});

您应该避免创建这样的全局变量，而是将它们放在一个对象中

var assignLetter = ["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","Z","X","Y","Z"];

var myVars = {};

divide("326,232,113")// input data

function divide(matrix){
    xyz = matrix.split(",");
    for(var i = 0;i < xyz.length; i++){
        myVars[assignLetter[i]] = xyz[i];
    }
}

console.log(myVars);
