pushing values to array nodejs
提问by Ben Scarberry
I need to display all events of user from his calendars. I get a list of all calendars and then loop through each one get events and try to store them in an array.
我需要从他的日历中显示用户的所有事件。我得到所有日历的列表，然后遍历每个获取事件并尝试将它们存储在一个数组中。
app.get('/getEventsList/', function (req, res) {
newArray = [];
function Done(){
console.log(newArray);
}
function getEventsforOneCalendar(token,calid){
gcal(token).events.list(calid, function(err, eventsList) {
newArray.push(eventsList);
});
}
function getEventsList(token) {
gcal(token).calendarList.list(function (err, calendarList) {
if (err) {
//handle error
} else {
calendars = calendarList.items;
forEach(calendars, function (item, index) {
getEventsforOneCalendar(token,item.id);
}, Done);
}
});
}
getEventsList('xxxxxxxxxxxtoken');
});
});
Problem is: that line newArray.push(eventsList);
问题是：那行 newArray.push(eventsList);
Any value even static passed in this line doesn't go like newArray.push('test'); and no error is thrown. if I log it I see it in the console, but it's never added to the array.
在这一行中传递的任何值甚至是静态的都不会像 newArray.push('test'); 并且不会抛出任何错误。如果我记录它，我会在控制台中看到它，但它从未添加到数组中。
What's possibly wrong?
可能有什么问题？

I simplest way can be like this. All it depends on how you want to show it.
我最简单的方法可以是这样。这一切都取决于你想如何展示它。
app.get('/getEventsList/', function (req, res) {
var newArray = [];
var total;
function display() {
console.log(newArray);
}
function getEventsforOneCalendar(token,calid){
gcal(token).events.list(calid, function(err, eventsList) {
newArray.push(eventsList);
if (total == newArray.length)
display();
});
}
function getEventsList(token) {
gcal(token).calendarList.list(function (err, calendarList) {
if (err) {
//handle error
} else {
calendars = calendarList.items;
total = calendars.length
forEach(calendars, function (item, index) {
getEventsforOneCalendar(token,item.id);
}, Done);
}
});
}
getEventsList('xxxxxxxxxxxtoken');
});
