createObjectURL 在 Chrome 中返回未定义 [英] createObjectURL is returning undefined in Chrome
问题描述
尝试使用 createObjectDataURL 更改视频源文件.它在 Firefox 中运行良好，但在 Chrome(版本 12.0.742.122 m)中无法运行.代码不会引发任何错误，但会为 createObjectDataURL 返回未定义.我尝试了所有的可能性，但它总是返回未定义.
<!DOCTYPE html><html><头><title>检查 CreateObjectURL</title></头><脚本类型=文本/javascript"语言=javascript">窗口.URL = 窗口.URL ||窗口.webkitURL;函数更改属性(){var v = document.getElementById("myvideo");var file = document.getElementById("fileControl").files[0];v.setAttribute("src",window.URL.createObjectURL(file));}</脚本><身体><video id="myvideo" src="movie.ogg" 控件></video><输入类型="文件" id="文件控制"/><button id="btnprops" onClick="ChangeProperty()" >更新</button></div></身体></html>请帮助我.它已经花费了很多时间.提前致谢.
解决方案 我在 Chrome 中将页面作为本地文件打开时遇到了同样的问题.我必须使用 Apache 并通过 localhost 打开它.

<script type="text/javascript" language="javascript">
window.URL = window.URL || window.webkitURL;
function ChangeProperty()
{
var v = document.getElementById("myvideo");
var file = document.getElementById("fileControl").files[0];
v.setAttribute("src",window.URL.createObjectURL(file));
}
</script>
<body>
<div >
<video id="myvideo" src="movie.ogg" controls ></video>
<input type="file" id="fileControl" />
<button id="btnprops" onClick="ChangeProperty()" >update</button>
</div>
</body>

解决方案 I had the same problem, when I was opening the page as a local file in Chrome. I had to use Apache and open it through localhost.
