formvalidation的ajax验证

 jQuery插件之表单验证插件validationEngine


普通验证的例子：http://www.position-relative.net/creation/formValidator/

ajax验证的例子：http://www.position-relative.net/creation/formValidator/demoSubmit.html

这个插件支持大部分的浏览器，但由于有使用到了css3的阴影和圆角样式，所以在IE浏览器下无法看到圆角和阴影效果(万恶的IE)。

插件包含三个文件：

jquery.validationEngine.js //插件主JS文件

jquery.validationEngine-cn.js //验证规则JS文件

validationEngine.jquery.css //样式表文件



使用方法：

( 1 ) 引入jquery和插件js、css文件

---------------------------------------------------------------------------------------------------------------------

<link rel="stylesheet" href="css/validationEngine.jquery.css" type="text/css" media="screen" charset="utf-8" />

<script src="js/jquery.js" type="text/javascript"></script>

<script src="js/jquery.validationEngine-cn" type="text/javascript"></script>

<script src="js/jquery.validationEngine.js" type="text/javascript"></script>

---------------------------------------------------------------------------------------------------------------------



( 2 ) 初始化插件

在页面head区域加入如下代码：

---------------------------------------------------------------------------------------------------------------------

$(document).ready(function() {

$("#formID").validationEngine() ; //formID是你要验证的表单ID

})

---------------------------------------------------------------------------------------------------------------------



( 3 ) 添加表单元素验证规则

验证规则写在表单元素的class属性内即可。如验证text文本框：

---------------------------------------------------------------------------------------------------------------------

<input value="" class="validate[required,custom[noSpecialCaracters],length[0,20],ajax[ajaxUser]]" type="text" name="user" id="user" />

---------------------------------------------------------------------------------------------------------------------

注：本例使用4个验证规则，各规则之间以“,”分隔。

required：不可为空

custom[noSpecialCaracters]：不能有特殊字符(这是一个自定义规则，自定义规则格式为custom[自定义规则名]，其中自定义规则在jquery.validationEngine-cn文件中定义。

length[0,20]：长度必须在0-20位之间。

ajax[ajaxUser]：这是一个Ajax验证，后面详细说明。



( 4 ) 验证触发

你可以在点击提交按钮后才触发验证

---------------------------------------------------------------------------------------------------------------------

$("#formID").validationEngine({

inlineValidation: false, //在这里修改

success : false,

failure : function() { callFailFunction() }

})

---------------------------------------------------------------------------------------------------------------------



默认的是在鼠标失去焦点后才开始验证，也就是绑定的是blur事件，可修改。

---------------------------------------------------------------------------------------------------------------------

$("#formID").validationEngine({

validationEventTriggers:"keyup blur", //这里增加了个keyup，也就是键盘按键起来就触发验证

success : false,

failure : function() { callFailFunction() }

})

---------------------------------------------------------------------------------------------------------------------



( 5) 修改错误提示层位置

---------------------------------------------------------------------------------------------------------------------

$("#formID").validationEngine({

promptPosition: "topRight", // 有5种模式 topLeft, topRight, bottomLeft, centerRight, bottomRight

success : false,

failure : function() {

})

---------------------------------------------------------------------------------------------------------------------



( 6) Ajax验证

---------------------------------------------------------------------------------------------------------------------

<input name="login_name" type="text" class="validate[ajax[ajaxUser]] text" id="login_name" >

---------------------------------------------------------------------------------------------------------------------

此验证要实现：在文本框中输入用户名，文本框失去焦点时检测用户名是否已被注册，如果已被注册显示提示“用户名已被使用”，如果还没有被注册则显示提示“用户名可以使用”。



此处使用了验证规则ajax[ajaxUser] ，看看jquery.validationEngine-cn中验证规则定义：

---------------------------------------------------------------------------------------------------------------------

"ajaxUser":{

"file":"validateUser.asp" //后台脚本文件，插件会POST三个参数：validateError；validateId；validateValue，后台脚本直接 request即可

"alertTextOk":"* 用户名可以使用.",

"alertTextLoad":"* 检查中, 请稍后...",

"alertText":"* 用户名已被使用."

},

---------------------------------------------------------------------------------------------------------------------

说明：后台脚本文件必须返回json格式数据。

插件官方提供的示例为php脚本，代码如下：

---------------------------------------------------------------------------------------------------------------------

<?php

$validateValue=$_POST['validateValue']; //获取post参数：文本框值

$validateId=$_POST['validateId']; //获取post参数：文本框ID

$validateError=$_POST['validateError'];

$arrayToJs = array(); //定义json返回数组，顺序必须为validateId、validateError、returnValue

$arrayToJs[0] = $validateId;

$arrayToJs[1] = $validateError;

if($validateValue =="karnius"){ //如果输入值=karnius

$arrayToJs[2] = "true"; // 返回 TRUE

echo '{"jsonValidateReturn":'.json_encode($arrayToJs).'}'; // 验证成功返回json数组

}else{

for($x=0;$x<1000000;$x++){

if($x == 990000){

$arrayToJs[2] = "false"; // 返回 TRUE

echo '{"jsonValidateReturn":'.json_encode($arrayToJs).'}'; // 验证失败返回json数组

}

}

}

?>

---------------------------------------------------------------------------------------------------------------------

由于本人程序使用的是ASP，参考官方提供的php后台脚本编写ASP代码如下：

---------------------------------------------------------------------------------------------------------------------

<%

validateValue = request("validateValue")

validateId = request("validateId")

validateError = request("validateError")

sql="select * from Cms_Personnel where login_name='"&validateValue&"'"

dbCon.sqlStr = sql

set rs = dbCon.rsDB()

if not rs.eof then

response.Write("{'jsonValidateReturn':['"&validateId&"','"&validateError&"','false']}")

else

response.Write("{'jsonValidateReturn':['"&validateId&"','"&validateError&"','true']}")

end if

%>

---------------------------------------------------------------------------------------------------------------------

说明：php的json_encode(mixed $value )函数能对变量进行JSON 编码。

asp中只要Rsponse

{"jsonValidateReturn":["validateId","validateError","returnValue"]}

形式字串即可。

注意response的JSON数组元素顺序，必须是validateId、validateError、returnValue 。

---------------------------------------------------------------------------------------------------------------------

再附一段JAVA的Ajax后台脚本代码:

---------------------------------------------------------------------------------------------------------------------

public String vali() {

ActionContext ac = ActionContext.getContext();

HttpServletRequest request = (HttpServletRequest) ac.get(ServletActionContext.HTTP_REQUEST);

String validateId = request.getParameter("validateId"); //获取插件post参数validateId

logger.info("vali() - String validateId=" + validateId);

String validateValue = request.getParameter("validateValue"); //获取插件post参数validateValue

String validateError = request.getParameter("validateError"); //获取插件post参数validateError

logger.info("vali() - String validateError=" + validateError);

jsonValidateReturn.add(validateId);

jsonValidateReturn.add(validateError);

if(validateValue.equals("chen"))

jsonValidateReturn.add("true");

else

jsonValidateReturn.add("false");

return SUCCESS;

}

----------------------------------
struts2-json-plugin的配置问题
JSON（Java Script Object Notation），是一种语言无关的数据交换格式。JSON插件是Structs 2 的Ajax插件，通过利用JSON插件，开发者可以很方便，灵活的利用Ajax进行开发。Json是一种轻量级的数据交换格式，JSon插件提供了一种名为json的Action ResultType 。一旦为Action指定了该结果处理类型，JSON插件就会自动将Action里的数据序列化成JSON格式的数据，并返回给客户端物理视图的JavaScript。简单的说，JSON插件允许我们在JavaScript中异步的调用Action，而且Action不需要指定视图来显示Action的信息显示。而是由JSON插件来负责具体将Action里面具体的信息返回给调用页面。

Json的数据格式可简单如下形式： person = { name: 'Jim',age: 18,gender: 'man'}。

如果action的属性很多，我们想要从Action返回到调用页面的数据。这个时候配置includeProperties或者excludeProperties拦截器即可。而这2个拦截器的定义都在struts2的json-default包内，所以要使用该拦截器的包都要继承自json-default。

Xml代码

<struts>  
     <constant name="struts.objectFactory" value="spring"/>        
     <include file="struts-admin.xml"></include>   
     <package name="default" extends="json-default">   
         <action name="person" class="com.person.PersonAction" method="view">  
         <result type="json">  
            <param name="includeProperties">              
             person\.name,persoon\.age,person\.gender              
            </param>>              
         </result>  
         </action>  
     </package>          
</struts> 
利用Struts 2的支持的可配置结果，可以达到过滤器的效果。Action的处理结果配置支持正则表达式。

但是如果返回的对象是一个数组格式的Json数据。比如peson Bean中有对象persion1...person9，而我只要person1的json数据，则可以用如下的正则表达式。

Xml代码

<struts>  
     <constant name="struts.objectFactory" value="spring"/>        
     <include file="struts-admin.xml"></include>   
     <package name="default" extends="json-default">   
         <action name="person" class="com.person.PersonAction" method="view">  
         <result type="json">  
            <param name="includeProperties">              
             person\[\d+\]\.person1   
            </param>>              
         </result>  
         </action>  
     </package>          
</struts> 
excludeProperties拦截器的用法与此类同，如果拦截的仅仅是一个对象，如果拦截掉person Bean的整个对象。

Xml代码

<struts>  
     <constant name="struts.objectFactory" value="spring"/>        
     <include file="struts-admin.xml"></include>   
     <package name="default" extends="json-default">   
         <action name="person" class="com.person.PersonAction" method="view">  
         <result type="json">  
            <param name="excludeProperties">              
             person   
            </param>>              
         </result>  
         </action>  
     </package>          
</struts> 
需要注意的是,如果用JSON插件把返回结果定为JSON。而JSON的原理是在ACTION中的get方法都会序列化，

所以前面是get的方法只要没指定不序列化，都会执行。

如果该方法一定要命名为get*（比如实现了什么接口），

那么可以在该方法的前面加注解声明该方法不做序列化。

注解的方式为：@JSON(serialize=false)

除此之外，JSON注释还支持如下几个域：

serialize：设置是否序列化该属性

deserialize：设置是否反序列化该属性。

format：设置用于格式化输出、解析日期表单域的格式。例如"yyyy-MM-dd'T'HH:mm:ss"。

//使用注释语法来改变该属性序列化后的属性名

@JSON(name="newName")

public String getName()

{

return this.name;

}

需要引入 import com.googlecode.jsonplugin.annotations.JSON;

@JSON(serialize=false)

public User getUser() {

    return this.User;

}

@JSON(format="yyyy-MM-dd")

public Date getStartDate() {

    return this.startDate;

}
