下面就是客戶端的JS的功夫了(selectfile.asp)

??? 里面還有一個小文件blank.htm用來定義文件和文件夾顯示的樣式

???? 調用的時候用以下函數，就可以實現以假亂真的服務器端選擇文件的效果
function selectfile()
{
var arr = showModalDialog("selectfile.asp?temp="+Math.random(), "", "dialogWidth:453px; dialogHeight:252px; status:0;help:1");
? if (arr != null)?
? {
?? return arr
? }
}
?????? 該函數最后返回的是選中的文件名,函數里面所使用的幾張圖片大家就自已從文件選擇框上抓了：）
