功能不響應按鈕單擊
[英]function not responding to button click
問題描述
我試圖在單擊按鈕時加載以下功能：
<button onclick="generateUpload()">Upload</button>
<script type="text/javascript" src="https://apis.google.com/js/api.js?onload=onApiLoad"></script>
<script type="text/javascript">
function generateUpload()
{
// The Browser API key obtained from the Google Developers Console.
var developerKey = 'ID';
// The Client ID obtained from the Google Developers Console.
var clientId = 'ID';
// Scope to use to access user's photos.
var scope = ['https://www.googleapis.com/auth/photos'];
var pickerApiLoaded = false;
var oauthToken;
// Use the API Loader script to load google.picker and gapi.auth.
function onApiLoad() {
gapi.load('auth', {'callback': onAuthApiLoad});
gapi.load('picker', {'callback': onPickerApiLoad});
}
function onAuthApiLoad() {
window.gapi.auth.authorize(
{
'client_id': clientId,
'scope': scope,
'immediate': true
},
handleAuthResult);
}
function onPickerApiLoad() {
pickerApiLoaded = true;
createPicker();
}
function handleAuthResult(authResult) {
if (authResult && !authResult.error) {
oauthToken = authResult.access_token;
createPicker();
}
}
// Create and render a Picker object for picking user Photos.
function createPicker() {
if (pickerApiLoaded && oauthToken) {
var picker = new google.picker.PickerBuilder().
enableFeature(google.picker.Feature.MULTISELECT_ENABLED).
addView(google.picker.ViewId.PDFS).
setOAuthToken(oauthToken).
setDeveloperKey(developerKey).
setCallback(pickerCallback).
build();
picker.setVisible(true);
}
}
// A simple callback implementation.
function pickerCallback(data) {
var url = 'nothing';
if (data[google.picker.Response.ACTION] == google.picker.Action.PICKED) {
var doc = data[google.picker.Response.DOCUMENTS][0];
url = doc[google.picker.Document.URL];
var message = 'The following(s) were stored in Parse: ' + url;
document.getElementById('result').innerHTML = message;
}
}
addOnOnApiLoadedCallback(onApiLoad); // register API load
}
var gapi_loaded = false, gapi_buffered_callbacks = [];
function onApiLoad() { // this function gets called by the Google API
gapi_loaded = true;
// run buffered callbacks
for (var i = 0; i < gapi_buffered_callbacks.length; i += 1) {
gapi_buffered_callbacks();
}
}
function addOnOnApiLoadedCallback(callback) {
if (gapi_loaded) {
callback(); // api is loaded, call immediately
} else {
gapi_buffered_callbacks.push(callback); // add to callback list
}
}
</script>
但是，它沒有響應，並且控制台上沒有顯示任何錯誤。 任何幫助將不勝感激。 我不知道它是如何被調用的，但是控制台上不會顯示任何錯誤提示，所以我不確定問題出在哪里。 該按鈕位於正文中，腳本位於標題中。

在generateUpload您要聲明函數，但不要從某個地方調用它們。 我認為您應該刪除所有這些函數，並從generateUpload內部調用它們。 例如
function generateUpload()
{
// The Browser API key obtained from the Google Developers Console.
var developerKey = 'ID';
// The Client ID obtained from the Google Developers Console.
var clientId = 'ID';
// Scope to use to access user's photos.
var scope = ['https://www.googleapis.com/auth/photos'];
var pickerApiLoaded = false;
var oauthToken;
// Use the API Loader script to load google.picker and gapi.auth.
//just call the function
onApiLoad();
//call the rest of your functions
}
在generateUpload之外實現oauthToken函數
function onApiLoad() {
gapi.load('auth', {'callback': onAuthApiLoad});
gapi.load('picker', {'callback': onPickerApiLoad});
}
按鈕不響應使用JQuery的單擊
