你好，我一直在努力学习jitsi。在我研究的一个特定部分，我必须截屏并在img对象上显示它。但不幸的是，我无法做到这一点。如果你们能帮助我，我将不胜感激。这对我来说至关重要。
先谢谢你
这就是我想在其中展示的img对象
var image = document.createElement('img');
image.src=url;
image.width=1000;
image.height=1000;
image.alt="here should be some image";
document.body.appendChild(image);
});下面是代码块：
myapp1js
function StartMeeting(){
const domain = 'meet.jit.si';
const options = {
roomName: 'alper2323',
width: 700,
height: 700,
parentNode: document.querySelector('#jitsi-meet-conf-container')
};
apiObj = new JitsiMeetExternalAPI(domain, options);
}
function HangupCall(){
apiObj.captureLargeVideoScreenshot().then(data => {
// data is an Object with only one param, dataURL
data.dataURL = "data:image/png;base64,iVBORw0KalpoAAAANSUhEUgAABQAA"
var blob = new Blob([data.dataURL], {type: "image/png"}),
url = URL.createObjectURL(blob),
img = new Image();
img.onload = function() {
URL.revokeObjectURL(this.src); // clean-up memory
document.body.appendChild(this); // add image to DOM
}
alert(url);
var image = document.createElement('img');
image.src=url;
image.width=1000;
image.height=1000;
image.alt="here should be some image";
document.body.appendChild(image);
});
