app.controller（'organization\u drill\u down'、['$scope'、'$firebaseArray'、'$firebaseObject'，'FBURL'，函数（$scope，$firebaseArray，$firebaseObject，FBURL）{

var mm=today.getMonth（）+1；
var yyyy=today.getFullYear（）；
如果（dd看起来像（从我可以通过识别和一些观察收集到的）您正在更新
users.orderByChild（）.equalTo（）部分之外的变量

Firebase函数（如您使用的函数）始终是承诺，在本例中，承诺将结束，然后运行
on（'value'，函数（snap）{

由于这是一个异步承诺，您可能会将空值保存到要在模式中使用的变量中。在尝试多次后，它最终会给承诺足够的时间来执行，以便获得正确的值

此外，请记住，在
上使用
将向firebase节点添加一个侦听器（在“值”更改的条件下），该侦听器将在每次满足条件时（而不仅仅是第一次调用代码时）运行您放入其中的任何代码.
您能建议我需要做哪些更改才能使其正常工作吗？我已经检查了您的代码，似乎您正在更新
部分的
中的变量。标识有点参差不齐，所以很难说（我建议改进它）.至于如何使它工作…如果我的答案是对的，那么你应该找到一种方法，将变量赋值放在第二个
on
函数中。另一方面，如果我错了，而你已经在那里了，那么不幸的是，我不知道是什么错了。
