Google Calendar javascript api - 添加多个事件 [英] Google Calendar javascript api - Add multiple events

问题描述

我试图通过javascript v3 api将多个事件添加到Google Calendar时遇到了问题。

我有一个数组，其中有条目事件如下：

  newEvent = {
summary：response [i] .name +BDay !!，
start：{
dateTime：date 
}，
end：{
dateTime：date 
} 
}; 
 
 events [i] = newEvent; 
  

之后，我打电话给Google Calendar api，以便添加事件：

  var request; 
 for（var j = 0; j< events.length; j ++）{
 
 console.log（events [j]）; 
 
 request = gapi.client.calendar.events.insert（{$ b $'calendarId'：calendarId，
'resource'：events [j] 
}）; 
 request.execute（function（resp）{
 console.log（resp）; 
}）; 
} 
  

然而，事实证明，所有事件都放置在同一日期日历（实际上是数组事件[]中的最后一个日期）。我相信这可能是因为请求是回调函数，但我不确定。

感谢您的帮助！

解决方案

事件[j] 正在for循环的每次迭代中被反弹。尝试使用匿名函数绑定到正确的事件：

  var request; 
 for（var j = 0; j< events.length; j ++）{
 
 console.log（events [j]）; 
 
 request = function（resource）{//返回请求的函数。 
 return gapi.client.calendar.events.insert（{$ b $'calendarId'：calendarId，
'resource'：resource 
}）; 
}（events [j]）; //绑定到当前事件。 
 request.execute（function（resp）{
 console.log（resp）; 
}）; 
 
 
 
 $ b $ p 
 $ b

以下是一个易于阅读的上述代码版本，它将所有处理过程转换为函数： 
 
 
  var makeRequest = function（resource）{
 console.log（resource）; 
 var request = gapi.client.calendar.events.insert（{$ b $'calendarId'：calendarId，
'resource'：resource 
}）; 
 request.execute（function（resp）{
 console.log（resp）; 
}）; 
}; （var j = 0; j< events.length; j ++）{
 makeRequest（events [j]）; 
 
 
} 
  
 
I've been facing a problem when I'm trying to add multiple events to a Google Calendar via javascript v3 api.


I have an array which entries are events like these:

newEvent = {
    "summary": response[i].name+" BDay!!",
    "start": {
      "dateTime": date
    },
    "end": {
      "dateTime": date
    }
  };

  events[i]=newEvent;

After, I make a call to Google Calendar api in order to add the events:
var request;
for(var j = 0; j<events.length; j++) {

  console.log(events[j]);

  request = gapi.client.calendar.events.insert({
    'calendarId': calendarId,
    'resource': events[j]
  });
  request.execute(function(resp) {
   console.log(resp);
 });
}
However, it turns out that all the events are placed in the same date into the calendar(which actually is the last date in array events[]). I believe that it could be because the requests are callback functions, but I'm not sure. 

Would appreciate the help!
解决方案
events[j] is being rebound on each iteration of the for loop. Try using an anonymous function to bind to the correct event:
var request;
for(var j = 0; j<events.length; j++) {

  console.log(events[j]);

  request = function(resource) {  // Function that returns a request.
    return gapi.client.calendar.events.insert({
      'calendarId': calendarId,
      'resource': resource
    });
  }(events[j]);  // Bind to the current event.
  request.execute(function(resp) {
    console.log(resp);
  });
}
See the following question for more details on JavaScript arrays and closures: JavaScript closure inside loops – simple practical example

Here is an easier-to-read version of the code above that moves all the processing into a function: 
var makeRequest = function(resource) {
  console.log(resource);
  var request = gapi.client.calendar.events.insert({
    'calendarId': calendarId,
    'resource': resource
  });
  request.execute(function(resp) {
    console.log(resp);
  });
};

for(var j = 0; j<events.length; j++) {
  makeRequest(events[j]);
}
