分享表单验证的高难度问题。
<% for i=1 to 22 %>
<tr>
<td colspan="2">
<input type="text" name="txt_item_no<%= i %>" size="22">
</td>
<td width="17%">
<input type="text" name="txt_date_make<%= i %>" size="16">
</td>
<td width="17%">
<input type="text" name="txt_term_use<%= i %>" size="18">
</td>
<td width="8%">
<input type="text" name="txt_num<%= i %>" size="8">
</td>
</tr>
<% next %>
提交时，要求：
1、
name="txt_term_use<%= i %>" 输入的文件格式必须为日期型式，并且格式为2004-01-08，并且输入的日期至少为“当前日期＋7天”，请问，怎么做？
2、
name="txt_num<%= i %>"的格式必须为数字形式。

1、ASP自动生成就OK了，防止别人更改，可以使用一个hidden，提交的时候提交hidden里的值
2、用正则表达式
<script language="javascript">
function checkform() {
var reg=/\d/g;
alert(document.all.length);
for (i=0;i<document.all.length;i++) {
if (document.all[i].type=="text") {
if (reg.test(document.all[i].value)) {
alert("OK");
} else {
alert("请重新输入内容！");
document.all[i].focus();
return false;
}
}
}
}
</script>
2、用正则表达式
<script language="javascript">
function checkform() {
var reg=/\d/g;
alert(document.all.length);
for (i=0;i<document.all.length;i++) {
if (document.all[i].type=="text") {
if (reg.test(document.all[i].value)) {
alert("OK");
} else {
alert("请重新输入内容！");
document.all[i].focus();
return false;
}
}
}
}
</script>

数字形式的INPUT

日期格式的INPUT
