扩展easyui 的表单验证 （转）

From:http://www.cnblogs.com/gengaixue/archive/2012/07/14/2591054.html

easyui 的validatebox()提供了自定义验证的方法，为此我把一些常用的数据验证汇总了一下，代码如下：

$.extend($.fn.validatebox.defaults.rules, {
    CHS: {
        validator: function (value, param) {
            return /^[\u0391-\uFFE5]+$/.test(value);
        },
        message: '请输入汉字'
    },
    ZIP: {
        validator: function (value, param) {
            return /^[1-9]\d{5}$/.test(value);
        },
        message: '邮政编码不存在'
    },
    QQ: {
        validator: function (value, param) {
            return /^[1-9]\d{4,10}$/.test(value);
        },
        message: 'QQ号码不正确'
    },
    mobile: {
        validator: function (value, param) {
            return /^((\(\d{2,3}\))|(\d{3}\-))?13\d{9}$/.test(value);
        },
        message: '手机号码不正确'
    },
    loginName: {
        validator: function (value, param) {
            return /^[\u0391-\uFFE5\w]+$/.test(value);
        },
        message: '登录名称只允许汉字、英文字母、数字及下划线。'
    },
    safepass: {
        validator: function (value, param) {
            return safePassword(value);
        },
        message: '密码由字母和数字组成，至少6位'
    },
    equalTo: {
        validator: function (value, param) {
            return value == $(param[0]).val();
        },
        message: '两次输入的字符不一至'
    },
    number: {
        validator: function (value, param) {
            return /^\d+$/.test(value);
        },
        message: '请输入数字'
    },
    idcard: {
        validator: function (value, param) {
            return idCard(value);
        },
        message:'请输入正确的身份证号码'
    }
});

/* 密码由字母和数字组成，至少6位 */
var safePassword = function (value) {
    return !(/^(([A-Z]*|[a-z]*|\d*|[-_\~!@#\$%\^&\*\.\(\)\[\]\{\}<>\?\\\/\'\"]*)|.{0,5})$|\s/.test(value));
}

var idCard = function (value) {
    if (value.length == 18 && 18 != value.length) return false;
    var number = value.toLowerCase();
    var d, sum = 0, v = '10x98765432', w = [7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2], a = '11,12,13,14,15,21,22,23,31,32,33,34,35,36,37,41,42,43,44,45,46,50,51,52,53,54,61,62,63,64,65,71,81,82,91';
    var re = number.match(/^(\d{2})\d{4}(((\d{2})(\d{2})(\d{2})(\d{3}))|((\d{4})(\d{2})(\d{2})(\d{3}[x\d])))$/);
    if (re == null || a.indexOf(re[1]) <) return false;
    if (re[2].length == 9) {
        number = number.substr(0, 6) + '19' + number.substr(6);
        d = ['19' + re[4], re[5], re[6]].join('-');
    } else d = [re[9], re[10], re[11]].join('-');
    if (!isDateTime.call(d, 'yyyy-MM-dd')) return false;
    for (var i = 0; i < 17; i++) sum += number.charAt(i) * w[i];
    return (re[2].length == 9 || number.charAt(17) == v.charAt(sum % 11));
}

var isDateTime = function (format, reObj) {
    format = format || 'yyyy-MM-dd';
    var input = this, o = {}, d = new Date();
    var f1 = format.split(/[^a-z]+/gi), f2 = input.split(/\D+/g), f3 = format.split(/[a-z]+/gi), f4 = input.split(/\d+/g);
    var len = f1.length, len1 = f3.length;
    if (len != f2.length || len1 != f4.length) return false;
    for (var i = 0; i < len1; i++) if (f3[i] != f4[i]) return false;
    for (var i = 0; i < len; i++) o[f1[i]] = f2[i];
    o.yyyy = s(o.yyyy, o.yy, d.getFullYear(), 9999, 4);
    o.MM = s(o.MM, o.M, d.getMonth() + 1, 12);
    o.dd = s(o.dd, o.d, d.getDate(), 31);
    o.hh = s(o.hh, o.h, d.getHours(), 24);
    o.mm = s(o.mm, o.m, d.getMinutes());
    o.ss = s(o.ss, o.s, d.getSeconds());
    o.ms = s(o.ms, o.ms, d.getMilliseconds(), 999, 3);
    if (o.yyyy + o.MM + o.dd + o.hh + o.mm + o.ss + o.ms < 0) return false;
    if (o.yyyy < 100) o.yyyy += (o.yyyy > 30 ? 1900 : 2000);
    d = new Date(o.yyyy, o.MM - 1, o.dd, o.hh, o.mm, o.ss, o.ms);
    var reVal = d.getFullYear() == o.yyyy && d.getMonth() + 1 == o.MM && d.getDate() == o.dd && d.getHours() == o.hh && d.getMinutes() == o.mm && d.getSeconds() == o.ss && d.getMilliseconds() == o.ms;
    return reVal && reObj ? d : reVal;
    function s(s1, s2, s3, s4, s5) {
        s4 = s4 || 60, s5 = s5 || 2;
        var reVal = s3;
        if (s1 != undefined && s1 != '' || !isNaN(s1)) reVal = s1 * 1;
        if (s2 != undefined && s2 != '' && !isNaN(s2)) reVal = s2 * 1;
        return (reVal == s1 && s1.length != s5 || reVal > s4) ? -10000 : reVal;
    }
};

页面中要引入jquery.js 和 easyui.min.js

html 代码中使用如下

<table class="grid" id="uiform">
<tr><td>登录名：</td><td><input  required="true" id="txtUsername" type="text" class="txt03" /></td><td>真实姓名：</td><td><input id="txtTruename" validType="CHS" required="true" type="text" class="txt03" /></td></tr>
<tr><td>登录密码：</td><td><input validType="safepass"  required="true" id="txtPassword" name="password" type="password" class="txt03" /></td><td>Email：</td><td><input id="txtEmail" name="email"  validType="email" type="text" class="txt03" /></td></tr>
<tr><td>身份证号：</td><td><input validType="idcard" id="txtIdcard" name="idcard" type="text" class="txt03" /></td><td>QQ：</td><td><input validType="QQ" id="txtQq" name="qq" type="text" class="txt03" /></td></tr>
<tr><td>手机：</td><td><input validType="mobile" id="txtMobile" name="mobile" type="text" class="txt03" /></td><td>电话：</td><td><input id="txtTel" name="tel" type="text" class="txt03" /></td></tr>
<tr><td>家庭住址：</td><td colspan="3"><input validType="equalTo[txtMobile]" style="width:80%" id="txtHomeaddr" name="homeaddr" type="text" class="txt03" /></td></tr>
<tr><td>备注：</td><td colspan="3"> <input type="text" style="width:80%" class="txt03" id="txtRemark"></textarea></td></tr>
<tr><td>&nbsp;</td><td colspan="3"><input id="Checkbox1" type="checkbox" /><label>超级管理员</label>&nbsp;&nbsp;<input id="Checkbox2" type="checkbox" /><label>禁用</label></td></tr>
</table>

这一段JS 是必不可少的

$(function(){
  $('#uiform input').each(function () {
            if ($(this).attr('required') || $(this).attr('validType'))
                $(this).validatebox();
        })
 });

这样就ok了

如果在提交时验证表单有没有通过验证，则可使用下面的代码

var flag = true;

$('#uiform input').each(function () {
    if ($(this).attr('required') || $(this).attr('validType')) {
    if (!$(this).validatebox('isValid')) {
        flag = false;
        return;
    }
    }
})

if (flag)
    alert('验证通过！');
else
    alert('验证失败！');

为了防止表单验证未通过时进行提交，必须：

<script type="text/javascript">
        $(function(){
            $('#ff').form({
                url:'form3_proc.php',
                onSubmit:function(){
                    return $(this).form('validate');
                },
                success:function(data){
                    $.messager.alert('Info', data, 'info');
                }
            });
        });
    </script>

jQuery EasyUI中进行表单验证主要是通过validatebox插件，看一个例子：

<h2>Form Validation Demo</h2>
    <div class="demo-info" style="margin-bottom:10px">
        <div class="demo-tip icon-tip">&nbsp;</div>
        <div>The form will not be submitted unless all the input value is valid.</div>
    </div>

    <div style="width:230px;background:#fafafa;padding:10px;">
        <div style="padding:3px 2px;margin-bottom:10px;border-bottom:1px solid #ccc">Form Validation</div>
        <form id="ff" method="post">
            <div>
                <label for="name">Name:</label>
                <input class="easyui-validatebox" type="text" name="name" required="true"></input>
            </div>
            <div>
                <label for="email">Email:</label>
                <input class="easyui-validatebox" type="text" name="email" required="true" validType="email"></input>
            </div>
            <div>
                <label for="subject">Subject:</label>
                <input class="easyui-validatebox" type="text" name="subject" required="true"></input>
            </div>
            <div>
                <label for="message">Message:</label>
                <textarea name="message" style="height:60px;"></textarea>
            </div>
            <div>
                <input type="submit" value="Submit">
            </div>
        </form>
    </div>
