如何在IE8,9中获取上传文件的大小?

How to get size of uploaded file in IE8,9 ?

推荐答案

您将需要使用Active X，因为那些版本的IE不支持HTML5 File API.我在网上找到了一个可以实现此目的的代码段.

You will need to use Active X as those versions of IE do not support the HTML5 File API. I found a code snippet on the web that does that.

function getSize()
{
    var myFSO = new ActiveXObject("Scripting.FileSystemObject");
    var filepath = document.upload.file.value;
    var thefile = myFSO.getFile(filepath);
    var size = thefile.size;
    alert(size + " bytes");
}

请参考此有关详细信息. 另请查看IE的API参考中输入类型=文件|"的备注"部分. 此处.

Refer this for details. Also take a look at the Remarks Section in the API Reference of IE for |input type=file| here.
