第一种方法：在form表单页面判断：
<SCRIPT LANGUAGE="JavaScript">
<!--
function check()
{
if(checkspace(document.表单名称.控件名.value)) {
document.表单名称.控件名.focus();
alert("请输入！");
return false;
}

}
function checkspace(checkstr) {
var str = '';
for(i = 0; i < checkstr.length; i++) {
str = str + ' ';
}
return (str == checkstr);
}
//-->
</SCRIPT>

<input type="submit" value="确定" name="submit" onClick="return check();"/>
第二种方法在执行sql语句页面判断：
<%
if strName="" then
response.Write"<script language=javascript> alert(""请输入!"");history.go(-1)</script>"
end if
%>
