本文介紹了在 javascript 中使用 API v3 檢索 Google 日歷事件的處理方法，對大家解決問題具有一定的參考價值，需要的朋友們下面隨著小編來一起學(xué)習(xí)吧！
問題描述
去年我使用的是這里找到的代碼 http://gdata-javascript-client.googlecode.com/svn/trunk/samples/calendar/simple_sample/simple_sample.html 從公共 Google 日歷的現(xiàn)在"檢索所有事件，然后顯示結(jié)果在一個網(wǎng)頁中.我修改了該代碼以滿足我的需要(請參閱下面的代碼).
last year I was using the code found here http://gdata-javascript-client.googlecode.com/svn/trunk/samples/calendar/simple_sample/simple_sample.html to retrieve all events from "now" of a public Google Calendar and then display the results in a webpage. I modified that code to match my needs (see the code below).
現(xiàn)在，使用 API v3，代碼不再工作，我無法理解哪些代碼行已被棄用以及如何更新它們.有人可以幫我處理這段代碼嗎?
Now, with API v3, the code doesn't work anymore and I'm not able to understand which lines of the code are deprecated and how to update them. Could please someone help me with this code?
非常感謝你:-)

已解決 :-) 這是使用 Google Calendar API v3 訪問和顯示 PUBLIC google Calendars 即將發(fā)生的事件的 javascript 代碼.
SOLVED :-) here's the javascript code to access and show upcoming events of PUBLIC google Calendars, with Google Calendar API v3.
