基于prototype.js验证框架(validation.js)的三个应用
最近对prototype.js用的比较多,同时发现了一个基于prototype.js的验证框架: [url=http://tetlaw.id.au/view/blog/really-easy-field-validation-with-prototype]validation.js really easy field validation with prototype[/url],下面是我在开发中用到的三个例子.前提条件:
首先要在html页面中引入几个js
Html代码
<
script type
=
'text
/
javascript' src
=
'..
/
script
/
prototype.js'
></
script
>
< script type = 'text / javascript' src = '.. / script / validation.js' ></ script >
< script type = 'text / javascript' src = '.. / script / effects.js' ></ script >
(可选)
< script type = 'text / javascript' src = '.. / script / validation.js' ></ script >
< script type = 'text / javascript' src = '.. / script / effects.js' ></ script >
加几段css
Html代码
input.disabled
{}
{
border: 1px solid #F2F2F2;
background-color: #F2F2F2;
} input.required, textarea.required {} {
border: 1px solid #00A8E6;
} input.validation-failed, textarea.validation-failed {} {
border: 1px solid #FF3300;
color : #FF3300;
}
input.validation-passed, textarea.validation-passed {} {
border: 1px solid #00CC00;
color : #000;
} .validation-advice {} {
margin: 5px 0;
padding: 5px;
background-color: #FF3300;
color : #FFF;
font-weight: bold;
}
应用一:该例子仅使用前台脚本进行验证
border: 1px solid #F2F2F2;
background-color: #F2F2F2;
} input.required, textarea.required {} {
border: 1px solid #00A8E6;
} input.validation-failed, textarea.validation-failed {} {
border: 1px solid #FF3300;
color : #FF3300;
}
input.validation-passed, textarea.validation-passed {} {
border: 1px solid #00CC00;
color : #000;
} .validation-advice {} {
margin: 5px 0;
padding: 5px;
background-color: #FF3300;
color : #FFF;
font-weight: bold;
}
需求:
查询条件
当CSO NO、AGREEMENT NO、流水号中任一项有值时,其他项都可为空
2. 当CSO NO、AGREEMENT NO、流水号三项都为空时,TARIFF CODE为必输,其他项选输
Javascript代码
window.onload
=
function
()
{
// 注册查询按钮事件
Event.observe("search", "click", function(){
var validator = Validation.get("IsEmpty");
if ([$F("csoNumber"), $F("agreementNumber"), $F("sequenceNumber")].all(validator.test)){
["required"].all(Validation.test.bind($("tariffCode")));
} });
应用二: 该例子通过ajax结合后台来进行验证
// 注册查询按钮事件
Event.observe("search", "click", function(){
var validator = Validation.get("IsEmpty");
if ([$F("csoNumber"), $F("agreementNumber"), $F("sequenceNumber")].all(validator.test)){
["required"].all(Validation.test.bind($("tariffCode")));
} });
需求:
sapid和password必输
且必须从后台数据库找到sapid和password对应的记录, 否则登陆不成功,并给出提示信息
Html代码
<
form
method
=post
action
="requisition.html"
id
= "frmLogin"
>
< table align = "center" style = "height:100%" >
< tr >
< td >
< fieldset style = "padding:10px" >
< legend > Login </ legend >
< table >
< tr >< td colspan = "2" >< input type = "hidden" id = "errMsg" ></ td ></ tr >
< tr >
< td class = "label" >< span class = "requiredFlag" > * </ span > SAP ID </ td >
< td >< input type ="text" name ="sapId" id = "sapId" class = "required" ></ td >
</ tr >
< tr >
< td class = "label" >< span class = "requiredFlag" > * </ span > Password </ td >
< td >< input type ="password" name ="password" id = "password" class = "required" ></ td >
</ tr >
< tr >
< td colspan = "2" align = "center" >< input type = "submit" class = "submit" value = "Login" >
< button class = "submit" onclick = "Login.goRegister()" > Register </ button ></ td >
</ tr >
</ table >
</ fieldset >
</ td >
</ tr >
</ table >
</ form >
Javascript代码
< table align = "center" style = "height:100%" >
< tr >
< td >
< fieldset style = "padding:10px" >
< legend > Login </ legend >
< table >
< tr >< td colspan = "2" >< input type = "hidden" id = "errMsg" ></ td ></ tr >
< tr >
< td class = "label" >< span class = "requiredFlag" > * </ span > SAP ID </ td >
< td >< input type ="text" name ="sapId" id = "sapId" class = "required" ></ td >
</ tr >
< tr >
< td class = "label" >< span class = "requiredFlag" > * </ span > Password </ td >
< td >< input type ="password" name ="password" id = "password" class = "required" ></ td >
</ tr >
< tr >
< td colspan = "2" align = "center" >< input type = "submit" class = "submit" value = "Login" >
< button class = "submit" onclick = "Login.goRegister()" > Register </ button ></ td >
</ tr >
</ table >
</ fieldset >
</ td >
</ tr >
</ table >
</ form >
window.onload
=
function
()
{
// 自定义验证器并注册到Validation中
var validatorName = "validate-login-info";
Validation.add(validatorName, "", function(){return false;}); // 验证器初始化
var validator = new Validation('frmLogin', {stopOnFirst:true, immediate:true}); // 提交前进行后台验证
Event.observe("frmLogin", "submit", function(ev){
var result = validator.validate();
if (result){
var request = new Ajax.Request(
"http://localhost:8080/agreement/CheckLoginInfo", // 提交的URL
{
method: 'get',
asynchronous: false,
parameters: Form.serialize("frmLogin"),
});
// 验证不通过,显示出错信息, 并中止提交操作!
var transport = request.transport;
if (transport.responseText != ""){
Validation.get(validatorName).error = transport.responseText;
[validatorName].all(Validation.test.bind($("errMsg")));
Event.stop(ev);
}
}
})
}
应用三:
// 自定义验证器并注册到Validation中
var validatorName = "validate-login-info";
Validation.add(validatorName, "", function(){return false;}); // 验证器初始化
var validator = new Validation('frmLogin', {stopOnFirst:true, immediate:true}); // 提交前进行后台验证
Event.observe("frmLogin", "submit", function(ev){
var result = validator.validate();
if (result){
var request = new Ajax.Request(
"http://localhost:8080/agreement/CheckLoginInfo", // 提交的URL
{
method: 'get',
asynchronous: false,
parameters: Form.serialize("frmLogin"),
});
// 验证不通过,显示出错信息, 并中止提交操作!
var transport = request.transport;
if (transport.responseText != ""){
Validation.get(validatorName).error = transport.responseText;
[validatorName].all(Validation.test.bind($("errMsg")));
Event.stop(ev);
}
}
})
}
需求:典型注册应用, 密码和确认密码的一致性验证
Html代码
<

< table align = "center" style = "height:100%" >
< tr >
< td >
< fieldset style = "padding:10px" >
< legend > Register </ legend >
< table >
< tr >
< td class = "label" >< span class = "requiredFlag" > * </ span > SAP ID </ td >
< td >< input type ="text" name ="sapId" id = "sapId" class = "required" ></ td >
</ tr >
< tr >
< td class = "label" >< span class = "requiredFlag" > * </ span > Password </ td >
< td >< input type ="password" name ="password" id ="password" class = "required" ></ td >

< td >< input type ="password" name ="repassword" id ="repassword" class = "validate-identical" ></ td >
</ tr >
< tr >
< td colspan = "2" align = "center" >< input type = "submit" class = "submit" value = "Register" ></ td >
</ tr >
</ table >
</ fieldset >
</ td >
</ tr >
</ table >
</ form >
< table align = "center" style = "height:100%" >

< legend > Register </ legend >
< table >
< tr >
< td class = "label" >< span class = "requiredFlag" > * </ span > SAP ID </ td >

< td >< input type ="password" name ="repassword" id ="repassword" class = "validate-identical" ></ td >
</ tr >
< tr >

</ tr >
</ table >
</ fieldset >
</ td >
</ tr >
</ table >
</ form >
Javascript代码
window.onload
=
function
()
{
// 添加password一致性验证
Validation.add("validate-identical", "the value of password and repassword must be identical", function(v){
return !Validation.get('IsEmpty').test(v) && v == $F("password");
}) // 验证器注册
var validator = new Validation('frmRegister', {stopOnFirst:true, immediate:true});
}
