Jquery验证只能验证表单吗，能验证表单里指定的DIV吗

   我现在要在注册页面上用Jquery写个验证，在网上看了好像都是整个表单的验证，我的页面里一个form分三步显示，用DIV分成3个注册步骤（第一个填写结束后点击下一步，验证成功的话，第一个DIV会被隐藏，显示第二个DIV的内容，每个DIV里面是一张表），怎样不提交表单，只验证 第一个DIV（步骤一）的内容呢？
  步骤一的内容有商家名称，密码，重复密码，email，qq等。

4 个解决方案

#1

都在表单中验证，如果是对前两个div的验证，全return false就可以了，第一个div通过，了第二个display设为block，第一个为none，第二个同样
只有第三个才检验是否正的通过，通过return true

#2

谢谢1楼的回答先，这是我从jsp页面简化出来的代码，这是form里DIV和table的分布，有点多

这是一段script代码，写进页面为什么会没反应，要改什么，插件已经引用

// JavaScript Document

$(document).ready(function()
{
	$("#regForm").validate(
	{
		//指定触发效验的方式
		event:"kryup" || "blur",
		//制定验证规则
		rules:{
			ei_CompanyName:{
				required:true,
				maxlength:100
			},
			ei_Name:{	
				required:true,
				maxlength:40
			},
			ei_Amount:	{
				requied:true,
				digits: true,
				range:[1,99]
			},
			ei_Address:	"required",
			ei_Pass:{ 	
				required:true, 
				rangelength:[5,20]
			},
			ei_Pass1:{ 	
				required:true, 
				equalTo:"#ei_Pass" 
			},
			ei_Mobile:{ 
				required:true, 
				Mobile:true,
				maxlength:15
			},
			ei_QQ:{ 	
				QQ:true 
			},
			ei_Email:{ 	
				email:true 
			},
			ei_Tel:{ 	
				Phone:true 
			},
			//自定义提示消息
			messages:{

				},

				},
				ei_Amount:{
					required:"请输入门店数量",

				},

				ei_Email:{ email:"Email格式有误" },
				ei_Paass1:{ required:"请输入确认密码", 
							equalTo:"两次输入的密码不一致" 
				},
				ei_Pass:{ 
					required:"请输入密码", 
					minlength:jquery.format("密码不能小于{0}位"), 
					maxlength:jquery.format("密码不能超过{1}位") 
				},
				ei_Mobile:{ 
					required:"请输入如手机号码", 
					Mobile:"手机号码格式有误",
					maxlength:jquery.format("最长不得超过15位")
				}
			},
			//验证消息放置的位置
			errorPlacement:function(){
				error.appendTo(element.parent("td").next("td"));
			},
			//对验证的表单设置高亮
			highlight:function(){

			}
		}
	});
})

只要指定到具体的id属性就行了
