Question

我目前正在尝试从另一个文件中提取一个函数，当我单击一个按钮时，该函数可用于对HTML进行更改（这将提供向您自己的Google日历添加事件信息的选项）。在我之前编写代码的人员使用Django的压缩程序来处理其他文件，而我试图弄清楚如何使用以下代码来调用函数。代码如下：

{% compress js file event-add %}
  <script src="{% static 'js/event/add.js' %}"></script>
{% endcompress %}
<script async defer src="https://apis.google.com/js/api.js"
  onload="this.onload=function(){};handleClientLoad()"
  onreadystatechange="if (this.readyState === 'complete') 
  this.onload()">
</script>

当我尝试时，我在控制台中收到错误

Uncaught ReferenceError: handleClientLoad is not defined
at HTMLScriptElement.onload

具体来说，我的handleClientLoad函数位于我的add.js文件中，必须与Google日历API的脚本一起使用，但是我一直在努力使该函数失效。

add.js文件设置如下（简称为仅显示我需要的功能）：

const AddEventForm = {
googleCalendar: () => {
const CLIENT_ID = 'my client id here';
const API_KEY = 'my api key here';

const SCOPES = "https://www.googleapis.com/auth/calendar.readonly";

const googleButton = document.getElementById('btn-gcalendar');

function handleClientLoad() {
  gapi.load('client:auth2', initClient);
}

function initClient() {
  gapi.client.init({
    apiKey: API_KEY,
    clientId: CLIENT_ID,
    scope: SCOPES
  }).then(function () {
    // Listen for sign-in state changes.

gapi.auth2.getAuthInstance().isSignedIn.listen(updateSigninStatus);

    // Handle the initial sign-in state.

updateSigninStatus(gapi.auth2.getAuthInstance().isSignedIn.get());
    googleButton.onclick = handleAuthClick;
  }, function(error) {
    appendPre(JSON.stringify(error, null, 2));
  });
}

function updateSigninStatus(isSignedIn) {
  if (isSignedIn) {
    googleButton.style.display = 'block';
  } else {
    googleButton.style.display = 'block';
  }
}

function handleAuthClick(event) {
  gapi.auth2.getAuthInstance().signIn();
}

function appendPre(message) {
  const pre = document.getElementById('main-content');
  const textContent = document.createTextNode(message + '\n');
  pre.appendChild(textContent);
}

function listUpcomingEvents() {
  gapi.client.calendar.events.list({
    'calendarId': 'primary',
    'timeMin': (new Date()).toISOString(),
    'showDeleted': false,
    'singleEvents': true,
    'maxResults': 10,
    'orderBy': 'startTime'
  }).then(function(response) {
    let events = response.result.items;
    appendPre('Upcoming events:');

    if (events.length > 0) {
      for (i = 0; i < events.length; i++) {
        let event = events[i];
        let when = event.start.dateTime;
        if (!when) {
          when = event.start.date;
        }
        appendPre(event.summary + ' (' + when + ')')
      }
    } else {
      appendPre('No upcoming events found.');
    }
  });
   }
  }
 }
