HTML5 AppCache 刷新 - 准确检测正在下载的文件
我通过注册事件来监视我的 HTML5 AppCache 事件，如下所示：
var appCacheEvents = ["checking", "error", "noupdate", "downloading", "progress", "updateready", "cached", "obsolete"];
for (var i = 0; i < appCacheEvents.length; i++) {
applicationCache.addEventListener(appCacheEvents[i], function (evt) {
// Code here to tell me the filename being downloaded???????
});
}
我对下载事件特别感兴趣。传递到函数中的 evt 对象似乎没有任何有关正在下载的文件的信息是否有办法检测正在下载的资源的名称？谢谢。
I am monitoring my HTML5 AppCache events by registering the events as follows:
var appCacheEvents = ["checking", "error", "noupdate", "downloading", "progress", "updateready", "cached", "obsolete"];
for (var i = 0; i < appCacheEvents.length; i++) {
applicationCache.addEventListener(appCacheEvents[i], function (evt) {
// Code here to tell me the filename being downloaded???????
});
}
I am particularly interested in the downloading event. The evt object that is passed into the function does not seem to have any info about the file being downloaded Is there anyway to detect the name of the resource being downloaded? Thanks.

您正在寻找“进度”事件，该事件会针对下载的每个文件而触发。

You're looking for the "progress" event, which fires for each file that is downloaded.
