<!--下段js引用的-->
<script type="text/javascript">
function checkType() {
var fileName = document.getElementById("FileUpLoad1").value;
var seat = fileName.lastIndexOf(".");
var extension = fileName.substring(seat).toLowerCase();
var allowed = [".jpg", ".gif", ".png", ".bmp", ".jpeg"];
for (var i = 0; i < allowed.length; i++) {
if (!(allowed[i] != extension)) {
return true;
}
}
alert("不支持" + extension + "格式");
return false;
}
</script>
