jQuery Validate验证框架详解

jQuery校验官网地址:http://bassistance.de/jquery-plugins/jquery-plugin-validation

一、导入js库

<script type="text/javascript" src="<%=path %>/validate/jquery-1.6.2.min.js"></script>
<script type="text/javascript" src="<%=path %>/validate/jquery.validate.min.js"></script>

注:<%=request.getContextPath() %>返回web项目的根路径。

二、默认校验规则

复制代码
(1)、required:true               必输字段
(
2)、remote:"remote-valid.jsp" 使用ajax方法调用remote-valid.jsp验证输入值
(
3)、email:true 必须输入正确格式的电子邮件
(
4)、url:true 必须输入正确格式的网址
(
5)、date:true 必须输入正确格式的日期,日期校验ie6出错,慎用
(
6)、dateISO:true 必须输入正确格式的日期(ISO),例如:2009-06-23,1998/01/22 只验证格式,不验证有效性
(
7)、number:true 必须输入合法的数字(负数,小数)
(
8)、digits:true 必须输入整数
(
9)、creditcard:true 必须输入合法的信用卡号
(
10)、equalTo:"#password" 输入值必须和#password相同
(
11)、accept: 输入拥有合法后缀名的字符串(上传文件的后缀)
(
12)、maxlength:5 输入长度最多是5的字符串(汉字算一个字符)
(
13)、minlength:10 输入长度最小是10的字符串(汉字算一个字符)
(
14)、rangelength:[5,10] 输入长度必须介于 5 和 10 之间的字符串")(汉字算一个字符)
(15)、range:[5,10] 输入值必须介于 5 和 10 之间
(16)、max:5 输入值不能大于5
(17)、min:10 输入值不能小于10
复制代码

三、默认的提示

复制代码
messages: {
required:
"This field is required.",
remote:
"Please fix this field.",
email:
"Please enter a valid email address.",
url:
"Please enter a valid URL.",
date:
"Please enter a valid date.",
dateISO:
"Please enter a valid date (ISO).",
dateDE:
"Bitte geben Sie ein g眉ltiges Datum ein.",
number:
"Please enter a valid number.",
numberDE:
"Bitte geben Sie eine Nummer ein.", digits: "Please enter only digits",
creditcard:
"Please enter a valid credit card number.",
equalTo:
"Please enter the same value again.",
accept:
"Please enter a value with a valid extension.",
maxlength: $.validator.format(
"Please enter no more than {0} characters."),
minlength: $.validator.format(
"Please enter at least {0} characters."),
rangelength: $.validator.format(
"Please enter a value between {0} and {1} characters long."),
range: $.validator.format(
"Please enter a value between {0} and {1}."),
max: $.validator.format(
"Please enter a value less than or equal to {0}."),
min: $.validator.format(
"Please enter a value greater than or equal to {0}.")
},
复制代码

如需要修改,可在js代码中加入:

复制代码
$.extend($.validator.messages, {
required:
"必选字段",
remote:
"请修正该字段",
email:
"请输入正确格式的电子邮件",
url:
"请输入合法的网址",
date:
"请输入合法的日期",
dateISO:
"请输入合法的日期 (ISO).",
number:
"请输入合法的数字",
digits:
"只能输入整数",
creditcard:
"请输入合法的信用卡号",
equalTo:
"请再次输入相同的值",
accept:
"请输入拥有合法后缀名的字符串",
maxlength: $.validator.format(
"请输入一个长度最多是 {0} 的字符串"),
minlength: $.validator.format(
"请输入一个长度最少是 {0} 的字符串"),
rangelength: $.validator.format(
"请输入一个长度介于 {0} 和 {1} 之间的字符串"),
range: $.validator.format(
"请输入一个介于 {0} 和 {1} 之间的值"),
max: $.validator.format(
"请输入一个最大为 {0} 的值"),
min: $.validator.format(
"请输入一个最小为 {0} 的值")
});
复制代码

推荐做法,将此文件放入messages_cn.js中,在页面中引入

<script type="text/javascript" src="<%=path %>/validate/messages_cn.js"></script>

四、使用方式
1、metadata用法,将校验规则写到控件中

复制代码
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":"
+ request.getServerPort() + path + "/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>

<head>

<base href="<%=basePath%>">

使用class="{}"的方式,必须引入包:jquery.metadata.js;
可以使用如下的方法,修改提示内容:class="{required:true,minlength:5,messages:{required:'请输入内容'}}";
在使用equalTo关键字时,后面的内容必须加上引号,如下代码:class="{required:true,minlength:5,equalTo:'#password'}"。

2、将校验规则写到js代码中

五、常用方法及注意问题
1、用其他方式替代默认的submit

复制代码
$(function(){
$("#signupForm").validate({
submitHandler:function(form){
alert("submit!");
form.submit();
}
});
});
复制代码

可以设置validate的默认值,写法如下:
$.validator.setDefaults({
submitHandler: function(form) { alert("submit!"); form.submit(); }
});

如果想提交表单,需要使用form.submit(),而不要使用$(form).submit()

2、debug,只验证不提交表单
如果这个参数为true,那么表单不会提交,只进行检查,调试时十分方便

$(function(){
$("#signupForm").validate({
debug:true
});
});

如果一个页面中有多个表单都想设置成为debug,用
$.validator.setDefaults({
debug: true
})

3、ignore:忽略某些元素不验证
ignore: ".ignore"

4、更改错误信息显示的位置
errorPlacement:Callback

Default: 把错误信息放在验证的元素后面
指明错误放置的位置,默认情况是:error.appendTo(element.parent());即把错误信息放在验证的元素后面
errorPlacement: function(error, element) {
     error.appendTo(element.parent());
}

//示例

复制代码
<tr>
<td class="label"><label id="lfirstname" for="firstname">First Name</label></td>
<td class="field"><input id="firstname" name="firstname" type="text" value="" maxlength="100" /></td>
<td class="status"></td>
</tr>
<tr>
<td style="padding-right: 5px;">
<input id="dateformat_eu" name="dateformat" type="radio" value="0" />
<label id="ldateformat_eu" for="dateformat_eu">14/02/07</label>
</td>
<td style="padding-left: 5px;">
<input id="dateformat_am" name="dateformat" type="radio" value="1" />
<label id="ldateformat_am" for="dateformat_am">02/14/07</label>
</td>
<td></td>
</tr>
<tr>
<td class="label">&nbsp;</td> <td class="field" colspan="2">
<div id="termswrap">
<input id="terms" type="checkbox" name="terms" />
<label id="lterms" for="terms">I have read and accept the Terms of Use.</label>
</div>
</td>
</tr>

errorPlacement: function(error, element) {

if (element.is(":radio"))

error.appendTo(element.parent().next().next());

else if (element.is(":checkbox"))

error.appendTo(element.next());

else

error.appendTo(element.parent().next());

}

复制代码

代码的作用是:一般情况下把错误信息显示在<td class="status"></td>中,如果是radio显示在<td></td>中,如果是checkbox显示在内容的后面

errorClass:String Default: "error"
指定错误提示的css类名,可以自定义错误提示的样式

errorElement:String Default: "label"
用什么标签标记错误,默认的是label你可以改成em

errorContainer:Selector
显示或者隐藏验证信息,可以自动实现有错误信息出现时把容器属性变为显示,无错误时隐藏,用处不大
errorContainer: "#messageBox1, #messageBox2"

errorLabelContainer:Selector
把错误信息统一放在一个容器里面。

wrapper:String
用什么标签再把上边的errorELement包起来

一般这三个属性同时使用,实现在一个容器内显示所有错误提示的功能,并且没有信息时自动隐藏
errorContainer: "div.error",
errorLabelContainer: $("#signupForm div.error"),
wrapper: "li"

5、更改错误信息显示的样式
设置错误提示的样式,可以增加图标显示,在该系统中已经建立了一个validation.css专门用于维护校验文件的样式

复制代码
input.error { border: 1px solid red; }
label.error {
background:url("./demo/images/unchecked.gif") no-repeat 0px 0px;
padding-left: 16px;
padding-bottom: 2px;
font-weight: bold;
color: #EA5200;
}
label.checked {
background:url("./demo/images/checked.gif") no-repeat 0px 0px;
}
复制代码

6、每个字段验证通过执行函数
success:String,Callback

要验证的元素通过验证后的动作,如果跟一个字符串,会当做一个css类,也可跟一个函数

success: function(label) {
// set
&nbsp; as text for IE
label.html("
&nbsp;").addClass("checked");
//label.addClass("valid").text("Ok!")
}

添加"valid"到验证元素, 在CSS中定义的样式<style>label.valid {}</style>
success: "valid"

7、验证的触发方式修改
下面的虽然是boolean型的,但建议除非要改为false,否则别乱添加。
a.onsubmit:Boolean Default: true
提交时验证. 设置唯false就用其他方法去验证
b.onfocusout:Boolean Default: true
失去焦点是验证(不包括checkboxes/radio buttons)
c.onkeyup:Boolean Default: true
在keyup时验证.
d.onclick:Boolean Default: true
在checkboxes 和 radio 点击时验证
e.focusInvalid:Boolean Default: true
提交表单后,未通过验证的表单(第一个或提交之前获得焦点的未通过验证的表单)会获得焦点
f.focusCleanup:Boolean Default: false
如果是true那么当未通过验证的元素获得焦点时,移除错误提示。避免和focusInvalid一起用

8、异步验证
remote:URL
使用ajax方式进行验证,默认会提交当前验证的值到远程地址,如果需要提交其他的值,可以使用data选项

复制代码
示例一:
remote: "check-email.php"
示例二:
remote: {
url:
"check-email.php", //后台处理程序
type: "post", //数据发送方式
dataType: "json", //接受数据格式
data: { //要传递的数据
username: function() {
return $("#username").val();
}
}
}
复制代码

远程地址只能输出"true"或"false",不能有其它输出。

9、添加自定义校验
addMethod:name, method, message
自定义验证方法

复制代码
// 中文字两个字节
jQuery.validator.addMethod(
"byteRangeLength",
function(value, element, param) {
var length = value.length;
for(var i = 0; i < value.length; i++){
if(value.charCodeAt(i) > 127){
length
++;
}
}
return this.optional(element) || (length >= param[0] && length <= param[1]);
}, $.validator.format(
"请确保输入的值在{0}-{1}个字节之间(一个中文字算2个字节)")
);

// 邮政编码验证

jQuery.validator.addMethod("isZipCode", function(value, element) {

var tel = /[1]{6}$/;

return this.optional(element) || (tel.test(value));

},
"请正确填写您的邮政编码");

复制代码

1.要在additional-methods.js文件中添加或者在jquery.validate.js添加
建议一般写在additional-methods.js文件中

2.在messages_cn.js文件添加:isZipCode: "只能包括中文字、英文字母、数字和下划线",
调用前要添加对additional-methods.js文件的引用。

10、radio和checkbox、select的验证

复制代码
1.radio的required表示必须选中一个
<input  type="radio" id="gender_male" value="m" name="gender" class="{required:true}" />
<input type="radio" id="gender_female" value="f" name="gender"/>

2.checkbox的required表示必须选中
<input type="checkbox" class="checkbox" id="agree" name="agree" class="{required:true}" />

checkbox的minlength表示必须选中的最小个数,maxlength表示最大的选中个数,rangelength:[2,3]表示选中个数区间

<input type="checkbox" id="spam_email" value="email" name="spam[]" class="{required:true, minlength:2}" />

<input type="checkbox" id="spam_phone" value="phone" name="spam[]" />
<input type="checkbox" id="spam_mail" value="mail" name="spam[]" />

3.select的required表示选中的value不能为空

<select id="jungle" name="jungle" title="Please select something!" class="{required:true}">

<option value=""></option>

<option value="1">Buga</option>

<option value="2">Baga</option>
<option value="3">Oi</option>

</select>

select的minlength表示选中的最小个数(可多选的select),maxlength表示最大的选中个 数,rangelength:[2,3]表示选中个数区间

<select id="fruit" name="fruit" title="Please select at least two fruits" class="{required:true, minlength:2}" multiple="multiple">

<option value="b">Banana</option>

<option value="a">Apple</option>

<option value="p">Peach</option>

<option value="t">Turtle</option>
</select>

复制代码
