javascript - 如何计算对象的值

Question

这是我的对象，我怎样才能获得所有 N 计数和所有 S 计数。至少我如何从该数组访问 N 和 Y 变量。

DoctorD:"N", DoctorE:"N", DoctorF:"N", DoctorG:"N", DoctorH:"N", DoctorI:"N", DoctorJ:"N", DoctorK:"N", DoctorL:"N", DoctorM:"N", DoctorN:"N", DoctorO:"N", DoctorP:"N", DoctorQ:"N", DoctorR:"N", DoctorS:"N", DoctorT:"N", DoctorU:"N", DoctorV:"Y", DoctorW:"N", DoctorX:"N", DoctorY:"N", DoctorZ:"N", DoctorAA:"N", DoctorAB:"N", DoctorAC:"N", DoctorAE:"N", DoctorAF:"N", DoctorAG:"N", DoctorAH:"N", DoctorAI:"N", DoctorAJ:"N", DoctorAK:"N", DoctorAL:"N", DoctorAM:"N", DoctorAN:"Y", DoctorAO:"Y", DoctorAP:"Y", DoctorA:"Y", DoctorAQ:"Y", DoctorAR:"Y", DoctorAS:"Y", DoctorAT:"N", DoctorAU:"Y", DoctorAV:"Y", DoctorAW:"Y", DoctorAX:"Y", DoctorB:"Y", DoctorAY:"Y", DoctorAZ:"Y", DoctorBA:"Y", DoctorBB:"Y", DoctorBC:"Y", DoctorC:"Y", DoctorBD:"Y", DoctorBE:"Y", DoctorBF:"Y"

在 javascript 中。任何帮助将不胜感激。这可能吗？或者还有其他解决方案来做到这一点？

您有一个关联数组，要迭代它，您可以使用 for in 循环。

var ary = { DoctorD:"N", DoctorE:"N", DoctorF:"N", DoctorG:"N", DoctorH:"N", DoctorI:"N", DoctorJ:"N", DoctorK:"N", DoctorL:"N", DoctorM:"N", DoctorN:"N", DoctorO:"N", DoctorP:"N", DoctorQ:"N", DoctorR:"N", DoctorS:"N", DoctorT:"N", DoctorU:"N", DoctorV:"Y", DoctorW:"N", DoctorX:"N", DoctorY:"N", DoctorZ:"N", DoctorAA:"N", DoctorAB:"N", DoctorAC:"N", DoctorAE:"N", DoctorAF:"N", DoctorAG:"N", DoctorAH:"N", DoctorAI:"N", DoctorAJ:"N", DoctorAK:"N", DoctorAL:"N", DoctorAM:"N", DoctorAN:"Y", DoctorAO:"Y", DoctorAP:"Y", DoctorA:"Y", DoctorAQ:"Y", DoctorAR:"Y", DoctorAS:"Y", DoctorAT:"N", DoctorAU:"Y", DoctorAV:"Y", DoctorAW:"Y", DoctorAX:"Y", DoctorB:"Y", DoctorAY:"Y", DoctorAZ:"Y", DoctorBA:"Y", DoctorBB:"Y", DoctorBC:"Y", DoctorC:"Y", DoctorBD:"Y", DoctorBE:"Y", DoctorBF:"Y"};

for (var key in ary) {
    if (ary.hasOwnProperty(key)) {
        var value = ary[key];
        console.log(value);
    }
}
