jquery - 使用jQuery获取两个数组的比率

我正在尝试开发一个分数栏，用户可以在其中查看他的分数，还可以看到他可以赢得的最高奖金的进度。

问题是在这个酒吧有8个奖项，每个奖项都有不同的奖励点。您可以通过仅收集200点来赢得小奖，或者可以通过收集50000点来赢得旅行。

现在的问题是我必须在栏上显示所有八个奖项里程碑，并且每个奖项里程碑之间的间隔都相同

如您所见，图片用户赢得了7800分，他现在达到了7500的里程碑，主要问题是我必须获得这些点之间的比率才能将瓶子放置在我做不到的准确位置上:(我努力了，但是nothig发生了

最佳答案

看起来似乎不太困难，但是7800并不是一个值得测试的值，因为它在7500到15000的范围内几乎与7500无关。(因此在JSfiddle中，我将其更改为12700)。

http://jsfiddle.net/Udwq9/9/

我修改为第二个for循环，以在里程碑大于用户得​​分时中断。

for(var j=0; j < ArrayLength; j++)
{
    if(yourPoints >= MileStone[j])
    {
        pos = pos + milestonepos;
    }
    else
    {
        prevMilestone = j ? MileStone[j-1] : 0;
        pos += parseInt( (yourPoints-prevMilestone)/(MileStone[j]-prevMilestone) * milestonepos);
        break;
    }
}
