javascript - 使用java脚本将数组转换为矩阵的最简单方法

Question

我已经写下了我的第一个 JavaScript 代码来在网页中进行一些动态渲染:

var c_names = ["Canada", "USA", "israel"]
var c_ids = [1, 2, 3]
var c_domaain = ["www.canada.com", "www.usa.com", "www.israel.com"]

var data_1 = []
var C_data = [
  ['Country', 'ids', 'Domain']
]
var x = 1


for (i = 0; i == 3; i++) {
  var x = x + 1
  data_1.push(c_name[x], c_ids[x], c_domain[x])
  for (i = 0; i < c_name.length; i++) {
    C_data.push(data_1)
  }
}

console.log(C_data)

我期待这样的输出:

 data = [ ['Country', 'ids', 'Domain'],
           ['USA', 1, 'www.usa.com'],
           ['Canada', 2, 'www.usa.com'],
           ['Israel', 3, 'www.usa.com'],
]

Answer 1

遍历其中一个数组，然后追加相应的项目。

var names   = ["Canada", "USA", "israel"]
var ids     = [1, 2, 3]
var domains = ["www.canada.com", "www.usa.com", "www.israel.com"]

var data = [
    ["Country", "ID", "Domain"]
]

names.forEach ((name, idx) => {
    data.push ([ name, ids [idx], domains [idx]]);
});

console.log(data)
