问题在于您没有根据国家增加计数。现在正在做小提琴

编辑:

我已经更新了小提琴:

我基本上是将cntryCnt变成一个对象文字,它将国家id作为一个属性,并保持每个id的正确计数,如下所示:

var cnt      = 0;
var cntryCnt = {};

...

// The function now receives the country id and increments the specific country clicks only.
var incCntryCount = function(id) {
       cntryCnt[id] = cntryCnt[id] || 0;
       cntryCnt[id]++;
       return cntryCnt[id];        
}
其余的更改在模板中,基本上只在获取或增加计数时将国家id作为参数发送

此外,这不是一个角度特定的问题,而是一个编程一般问题
