    jquery ajax校验
 

 
/**************jquery ajax校验***************************************************/
function onclickXml(name){
              
     var hotelId=$("#hotelId").val();
     if(name.value ==''||name.value.length==0){
			alert('输入的用户名为空！');
	 		return false;
	 }
     else
     {
     alert("aaaaa");
         $.ajax({
		           type: "POST",
		           url: "<%=request.getContextPath()%>/hotelManage.do?method=ajaxValidateName",
		           data: "uname="+name.value,
		           success: function(msg){
			         alert(msg);			  
		           }
		        });
      }
    
  }

prototype ajax校验

 /**************prototype ajax校验***************************************************/ 
function validateName(name){
 
    var   url="<%=request.getContextPath()%>/hotelManage.do?method=ajaxValidateName";
   var pars="hotelId="+encodeURI(encodeURI($("#hotelId").val()))+"&name="+encodeURI(encodeURI(name.value));//解决中文乱码问题
        var myAjax = new Ajax.Request(
        url,
        {
        method: 'post',
        parameters: pars,
        onComplete: showResponse
        });
  }
function showResponse(originalRequest)
{
  // var tt = originalRequest.responseText;
   alert(originalRequest.responseText);
 // $("#loading").html("<font color='red'>该名称已存在!</font>");  
 //  $("#loading").show(); 
}

jsp代码

<input type="hidden" name="hotelId" id="hotelId" value="<c:out value='${hotelId}'/>"/>
  名称：<input name="name" id="name" value="" type="text" size="16" onblur="validateName(this);"/><!--onclickXml(this) -->

后台action

	public ActionForward ajaxValidateName(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws Exception
	{
		HotelBusIface service = (HotelBusIface) this.getObject();
		String name = URLDecoder.decode(request.getParameter("name"),"UTF-8");
		String hotelId = request.getParameter("hotelId");
		PrintWriter out = response.getWriter();
		System.out.println(name+"-----"+hotelId);

		if(service.existImageName(hotelId, name))
		{
			System.out.println("exist");
			out.println("exist");
		}else
		{
			System.out.println("noexist");
			out.println("noexist");
		}
        return  null;
	}
