<html>
<head>
<script type="text/javascript">
function suffixalWord(){
var len = document.getElementById("file").value.length;
if(document.getElementById("file").value.substring(len-3,len) != "doc"){
document.getElementById("form").reset();
alert("上传的文档不是Word，请重新选择");
}else document.getElementById("form").submit();
}
</script>
