应该在不使用任何验证控件的情况下进行验证
我的意思是形式被设计为
Textbox1(必填字段验证)
textbox2(电子邮件验证)
Textbox3(数值验证)
Textbox4(无特殊字符验证)
Textbox5(字母数字验证)
Textbox6(日期验证)
在这里，我需要在asp.net中使用Java脚本而不在工具箱中使用任何验证控件的代码.....
并给我有关如何在Asp.net中进行操作的信息
我已经尝试了很多，但是我没有得到解决方案，JavaScript代码应该写在哪里，asp.net代码应该写在哪里.它是如何工作的...

推荐答案
看看jQuery，它可以帮助您验证用户输入: http://docs.jquery.com/Plugins/Validation [
Take a peek at jQuery, which is able to help you validating user inputs : http://docs.jquery.com/Plugins/Validation[^]
必须将<script>块写在<head>内或<body>标记，您已将其保留在根目录中，这是无效的，将其移至head即可.
如果解决您的问题，则将其标记为答案，这会激发:)...
the<script>block must be written eighter inside<head>or<body>tag, you have kept it in root, which is invalid, shift it to head, it will work.
mark as answer if solves your problem, it motivates :)...
function checkEmpty()
{
if (document.getElementById("Textbox1").value=="")
{
alert("Please enter value in textbox1");
document.getElementById("Textbox1").focus();
return false;
}
}
function checkEmpty()
{
filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+
