[英]JavaScript declared global variable can't assign in method
I have some JavaScript code where I have a variable that I've declared outside the function however I can't seem to assign it. 我有一些JavaScript代码,其中有一个已在函数外部声明的变量,但是似乎无法分配它。
I've looked around and am doing the generally accepted thing of assigning outside the function but still have issues. 我环顾四周,正在做通常接受的在函数外部分配的事情,但是仍然有问题。
Any ideas? 有任何想法吗?
var numberPeopleSignedIn;
function setWaitTime(id, currentTimeToMinus){
var peopleAvailable = [];
hoodie.store.findAll('barber')
.done(function(object) {
object.forEach(function(barber) {
if (barber.statusInOut == "signedIn") {
peopleAvailable.push(barber);
}
numberPeopleSignedIn = peopleAvailable.length;
});
});
console.log(numberPeopleSignedIn); //This is returning undefined
}
findAll()
is returning a delegate. findAll()
返回一个委托。 Meaning the console.log is being called before the .done()
function when numberPeopleSignedIn
is still undefined. 这意味着当
numberPeopleSignedIn
仍未定义时,在.done()
函数之前调用console.log。
