以下是代码部分，测试过，浏览器支持getUserMedia方法的。我实在找不出错误，两个回调函数函数都没有进入。求解！！！<!DOCTYPE html><html><head><meta charset="UTF-8"><title>WebRTC通信</title></head><body><h1>访问本地摄像头</h1><video id="myVideo" width="1024" height="888" autoplay="true"></video></body><script type="text/javascript">window.onload = function(){navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia;window.URL = window.URL || window.webkitURL;navigator.getUserMedia({video:true, audio:true}, //访问本地设备成功时的回调函数//stream为同步媒体数据流function(stream) {var video = document.getElementById('myVideo');if (window.URL) {video.src = window.URL.createObjectURL(stream);}else{video.src = stream;}},//访问本地设备失败时的回调函数function (err) {console.log(err);});}</script></html>
