您好,我的主要目标是从谷歌日历中获取所有事件,并在下方显示其名称以及日期(和时间,如果有)。我正在使用 javascript google calendar api v3,并且在获取每个事件的日期时遇到了麻烦。在我进一步解释我的问题之前,这里是当前代码:
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 将偶尔返回日期,但有时只是返回未定义。那我还能如何获取活动的日期呢?
我解决这个问题的想法是循环遍历每个月的每一天并获取当天的所有事件。但是,当我尝试为所需日期添加带有 RFC3339 时间戳的 timeMax 和 timeMin 参数时,它没有返回任何内容。有人可以为我提供一个实现这一目标的例子吗?
任何帮助是极大的赞赏。
