javascript - 为什么这个标记为 javaScript 继续不起作用？

Question

我正在使用这段代码来防止一些圆圈重叠:

iCantThinkOfAGoodLabelName:
x = genX(radius);
y = genY(radius);
for(i in circles) {
  var thisCircle = circles[i];
  if(Math.abs(x-thisCircle["x"])+Math.abs(y-thisCircle["y"])>radius*2) { //No overlap
    continue;
  } else { //Overlap
    continue iCantThinkOfAGoodLabelName; //<- Line 256
  }
  thisCircle = [];
}

但是当到达 continue 语句时，chrome 的开发者控制台给了我这个:client.html:256 Uncaught SyntaxError: Undefined label 'iCantThinkOfAGoodLabelName'

Answer 1

标签应该紧接在循环之前

x = genX(radius);
y = genY(radius);

iCantThinkOfAGoodLabelName:
for(i in circles) {
