为什么此代码导致无限循环？

Question

我不能为我的生活找出为什么这不起作用。

var refP = []; 
var distance = function (p1, p2) { 
    return dist(p1.x, p1.y, p2.x, p2.y); 
} 
while (refP.length < 24) { 
    var pusher = { 
     x: -1, 
     y: -1, 
     closestRefP: 9999999 
    }; 
    pusher.x = (random(0, 400)); 
    pusher.y = (random(0, 400)); 
    for (var d = 0; d < refP.length; d++) { 
     if (distance(pusher, refP[d]) < pusher.closestRefP) { 
      pusher.closestRefP = distance(pusher, refP[d]); 
     } 
    } 
    if (pusher.closestRefP > 2) { 
     refP[refP.length] = pusher; 
    } 
} 

当我删除最后一条if语句并且无条件地将推送器推送到refP时，它不会给我循环。

谢谢。请让我知道是否应该清理此代码，或者尝试用较少的代码隔离问题。

您确定您的random和dist功能正常吗？

var distance = function (point1, point2) { 
    var xs = 0; 
    var ys = 0; 

    xs = point2.x - point1.x; 
    xs = xs * xs; 

    ys = point2.y - point1.y; 
    ys = ys * ys; 

    return Math.sqrt(xs + ys); 
} 

和您的通话random(0, 400)此：

与更换您的distance功能

pusher.x = Math.floor(Math.random() * 400); 
pusher.y = Math.floor(Math.random() * 400);
