photo-sphere-viewer.js是一個基于three.js的全景插件
1、能添加熱點；
2、能呼叫陀螺儀；
3、操作簡單，提供一張全景圖片即可（大多數手機都可以拍攝）
官網：https://photo-sphere-viewer.js.org/
使用方法很簡單，直接去官網參考example和api使用檔案，github上下載原始碼即可，
建議不要找網上的，版本太老，api用法都不太一樣了，功能也沒有新版的完善，
1、直接訪問全景圖（移動端自動呼叫陀螺儀）

#viewer {

height: 100vh;
}
</style>
<script>var viewer = new PhotoSphereViewer.Viewer({
container: document.querySelector('#viewer'),
panorama: 'budi.jpg',
plugins: [
PhotoSphereViewer.GyroscopePlugin,
],
lang: {
gyroscope : 'Gyroscope',
},
});
// 如果是移動端
if(/Android|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)) {
viewer.once('ready', function(){
document.querySelector('.psv-gyroscope-button').click();
});
}
</script>
</body>
</html>
注意：Photo Sphere Viewer的陀螺儀必須在https下才能開啟，否則無效！！！
2、使用iframe訪問全景圖
這種情況下存在跨域iframe問題，需要使用post message進行父子組件通信
(1)【父組件】iframe.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>全景圖跨域iframe版-子組件</title>
<style>
*{
margin:0;
padding:0;
}
html,body,iframe {
width: 100%;
height: 100%;
}
</style>
</head>
<body>
<iframe id="iframe" frameborder="no" border="0" marginwidth="0" marginheight="0" src="https://xxx.xxx.com/vr.html" scrolling="no" allowTransparency="true"></iframe>
<script>
if (window.DeviceOrientationEvent) {
window.addEventListener("deviceorientation", handleOrientation, false); // 組件iframe層 -- VR iframe層
} else {
alert("您的瀏覽器不支持HTML5 DeviceOrientation介面");
}
function handleOrientation(orientData){
var absolute = orientData.absolute;
var alpha = orientData.alpha;
var beta = orientData.beta;
var gamma = orientData.gamma;
// Do stuff with the new orientation data
var val = {
"act": "gyroscope",
"val": {
alpha: alpha,
beta: beta,
gamma: gamma
}
};
//獲取iframe
var ifr = document.querySelector('#iframe');
//iframe的路徑
var url = 'https://xxx.xxx.com/vr.html';
ifr.contentWindow.postMessage(JSON.stringify(val), url);
}
</script>
</body>
</html>
(2)【子組件】vr.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>全景圖跨域iframe版-子組件</title>
<link rel="stylesheet" href="libs/photo-sphere-viewer.min.css"/>
<script src="libs/three.min.js"></script>
<script src="libs/browser.min.js"></script>
<script src="libs/photo-sphere-viewer.min.js"></script>
<script src="libs/gyroscope.js"></script>
<div id="viewer"></div>
<style>
/* the viewer container must have a defined size */
*{
margin:0;
padding:0;
}
#viewer {
width: 100vw;
height: 100vh;
}
</style>
<script>
// 接收訊息
if(top !== self) {
window.parent.postMessage("gyroscope", '*');
}
window.onmessage = function(event) {
var data = eval('(' + event.data + ')');
if (data.act === 'gyroscope') {
window.deviceOrientation = data.val;
}
}
var viewer = new PhotoSphereViewer.Viewer({
container: document.querySelector('#viewer'),
panorama: 'budi.jpg',
plugins: [
PhotoSphereViewer.GyroscopePlugin,
],
lang: {
gyroscope : 'Gyroscope',
},
});
// 如果是移動端
if(/Android|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)) {
viewer.once('ready', function(){
document.querySelector('.psv-gyroscope-button').click();
});
}
</script>
</body>
</html>
(3) 修改gyroscope.js （跟我需求一樣的小伙伴直接復制替換即可）
