如何访问数组数组中的每个元素？

  • 772

我需要处理每个坐标，但事实证明我指的是第一个和第二个子数组。正确吗？

    let rings =   
[[2279206.7663000003, 6068865.9603 ],
[ 2279208.3274999997, 6068823.1731 ],
[ 2279207.6547, 6068793.376 ],
[ 2279205.1052, 6068771.1369 ],
[ 2279039.6064, 6068432.769099999 ]]

rings.forEach(function() {     
    let point = { x: rings[0], y: rings[1] }; 
    console.log(point)
});

    let rings = [
  [ 2279206.7663000003, 6068865.9603 ],
  [ 2279208.3274999997, 6068823.1731 ],
  [ 2279207.6547, 6068793.376 ],
  [ 2279205.1052, 6068771.1369 ],
  [ 2279039.6064, 6068432.769099999 ]
];

rings.forEach(function(item) {     
  let point = { x: item[0], y: item[1] }; 
  console.log(point)
});
