使用javascript google calendar api v3从某一天获取活动

您好我的主要目标是从谷歌日历中获取所有活动,并在下方显示其日期(如果可用的话)的名称.我正在使用javascript google calendar api v3并且遇到了抓住每个事件的日期的麻烦.在我进一步解释我的问题之前,这里是当前的代码：

var clientId = '200816328603.apps.googleusercontent.com';
var apiKey = 'AIzaSyD3rbV__d8u6r9u5GioBU0oVwa-53YXRqM';
var scopes = 'https://www.googleapis.com/auth/calendar';

function handleClientLoad() {
  gapi.client.setApiKey(apiKey);
  window.setTimeout(checkAuth,1);
  checkAuth();
}

function checkAuth() {
  gapi.auth.authorize({client_id: clientId, scope: scopes, immediate: true},
      handleAuthResult);
}

function handleAuthResult(authResult) {
  var authorizeButton = document.getElementById('authorize-button');
  if (authResult) {
    authorizeButton.style.visibility = 'hidden';
    makeApiCall();
  } else {
    authorizeButton.style.visibility = '';
    authorizeButton.onclick = handleAuthClick;
   }
}

function handleAuthClick(event) {
  gapi.auth.authorize(
      {client_id: clientId, scope: scopes, immediate: false},
      handleAuthResult);
  return false;
}

//document.createTextNode(resp.items[i].summary)

function makeApiCall() {

  gapi.client.load('calendar', 'v3', function() {
    var request = gapi.client.calendar.events.list({
      'calendarId': 'pvhs.k12.nj.us_r6jaor04o80hpsaldf17civeio@group.calendar.google.com'
    });

    request.execute(function(resp) {
      for (var i = 0; i < resp.items.length; i++) {

        //---------nodes for html elements
        var title = document.createTextNode(resp.items[i].summary); //titles are undefined so I'm using the summary as title instead
        //var description = document.createTextNode(resp.items[i].description); //there are no descriptions apparently
        var date = document.createTextNode('Start: ' + resp.items[i].start.date + ' End: ' + resp.items[i].end.date); //resp.items[i].date returns undefined

        //---------html elements
        var div = document.createElement('div');
        div.className = resp.items[i].summary;

        var h1 = document.createElement('h1');
        h1.appendChild(title);
        div.appendChild(h1);

        //loop is to filter out all the undefined
        if (date.textContent != 'Start: undefined End: undefined') {
          var p = document.createElement('p');
          p.appendChild(date);
          div.appendChild(p);
        }

        document.body.appendChild(div);
      }
    });
  });
}

现在resp.items [i] .start.date和resp.items [i] .end.date会偶尔返回日期,但有时只返回undefined.那我怎么能抓住活动的日期呢？

我想解决这个问题的方法是在每个月的每一天进行循环并抓住当天的所有事件.但是,当我尝试使用RFC3339时间戳添加timeMax和timeMin参数时,它没有返回任何内容.有人能为我提供一个实现这个目的的例子吗？

任何帮助是极大的赞赏.

解决方法:

为了使用timeMin或timeMax,你需要将’singleEvents’设置为true,我相信它会返回重复事件的个别实例,而不是事件组.

var request = gapi.client.calendar.events.list({
        'calendarId': 'pvhs.k12.nj.us_r6jaor04o80hpsaldf17civeio@group.calendar.google.com',
        'singleEvents': true, /* required to use timeMin */ 
        'timeMin': '2013-02-01T11:43:22.000Z'
    });

希望有所帮助.
