Javascript 未使用IE8触发Jquery事件

我正在使用blueimp的fileupload javascript小部件和jQuery 1.9.0将文件上载到服务器，我在IE8中没有触发一个事件，IE8是我的项目所需的浏览器之一

因此，由于这个原因，我无法打开窗口浏览文件。如果我从IE8控制台执行$（'#fileupload'）。click（），它会工作，但代码没有成功

我认为这是因为事件的泡沫，但我向你们展示了自己决定的代码。我还认为样式对这个问题很重要，因为我在真正的fileupload小部件上使用的样式按钮可能与它重叠。也许像不透明度和位置这样的css样式很重要

这已经开放足够长的时间了。看起来@Sampson是对的，IE8不支持文件的JSAPI。

哪个版本的jQuery？只有1.x版本支持IE8。老IE和新IE之间的attachEvent/addEventListener差异可能存在问题。jQuery的版本是1.9.0@jonathansampson您能在JSFIDLE上安装一个复制程序让我们直接调试吗？您必须在更新版本的IE或其他浏览器中构建复制。@JonathanSampson单击“浏览”为我打开文件上载窗口。除此之外，如果你想获得IE8支持，你应该知道，

files

属性直到IE10才得到支持。
