例如有 str="../../test.jsp"或.doc .txt .thml
如何取.jsp做判断,认定文件类型
<INPUT TYPE="file" name=vvv>
<INPUT TYPE="button" onclick=aaa()>
<script>
function aaa()
{
str = document.all.vvv.value;
dd=str.indexOf(".")
alert(document.all.vvv.value.substring(dd+1, str.length)+"文件");
}
</script>
num = str.lastIndexOf(".");
fileType = str.substr(num);
