使用浏览器开发者工具查看这个js是否404还是200或304
发布网站通过http协议访问，而且确保你的swf没有被浏览器禁用，默认flash不是最新版本是被浏览器禁用的，需要人工点击允许运行后，刷新页面才会注册capture这个方法var source = '<object id="XwebcamXobjectX" type="application/x-shockwave-flash" data="'+webcam["swffile"]+'" width="'+webcam["width"]+'" height="'+webcam["height"]+'"><param name="movie" value="'+webcam["swffile"]+'" /><param name="FlashVars" value="mode='+webcam["mode"]+'&quality='+webcam["quality"]+'" /><param name="allowScriptAccess" value="always" /></object>'; if (null !== webcam["extern"]) {
$(webcam["extern"])[webcam["append"] ? "append" : "html"](source);
} else {
this[webcam["append"] ? "append" : "html"](source);
} var run = 3;
(_register = function() {
var cam = document.getElementById('XwebcamXobjectX'); if (cam && cam["capture"] !== undefined) { /* Simple callback methods are not allowed :-/ */
webcam["capture"] = function(x) {
try {
return cam["capture"](x);
} catch(e) {}
}

jquery attr prop 区别
document.getElementById('XwebcamXobjectX').capture();
document.getElementById('XwebcamXobjectX').save();
就不报错了
document.getElementById('XwebcamXobjectX').capture();
document.getElementById('XwebcamXobjectX').save();还是会报错
