高分求救,firefox,jsp文件上传
纯jsp项目,无servlet
在firefox浏览器里如何获得上传文件路径。。。
求代码。。。能用的

------解决方案--------------------
探讨

<input type="file" id="file"/>
var 文件路径 = document.getElementById("file").value

------解决方案--------------------
一般的真不行还是你代码有误,说实话以前还真没注意过。莫非firefox还不支持html的file标签了....
------解决方案--------------------
FF3现在好像是不支持了。 要改为通用的有些麻烦。
在网上找了一个。可用
