使用jquery.validation+jquery.poshytip做表单验证--未完待续
jqueryValidate的具体使用方法很多，这里就不在赘述，这一次只谈一下怎样简单的实现表单验证。
整片文章目的，通过JQvalidation按表单属性配置规则验证，并将验证结果通过poshytip来更灵活的展示在不同的位置。
这里有个问题通过表单标签定义规则不能实现高级复杂的验证，所以复杂的验证还是要通过js去单个实现。
效果如下：
第一步：为表单配置验证属性，实现验证规则的随心所欲。
目的：通过js的引用配置，可以实现对自己定义的标签属性指定json格式的验证规则。
页面引入js
<script src="~/js/jquery-migrate-1.8.1.min.js"></script>
<script src="~/Scripts/jquery.validate.js"></script>
<script src="~/Scripts/jquery.metadata.js"></script>//封装了对validate更简洁的调用
简单验证方式
<input id="ssp" class="required" />
引用metadata之后就可以所有直接标签定义验证内容和错误消息
重点：这里注意 required 前后的空格，可以查看metadata中的规则，空格是一种书写格式必须保留。
<input class="{validate:{ required :true},messages:{ required:'请输入名称' }}" id="ssp" />
但这样会影响到表单正常的样式设置，所以可以通过metadata来修改。这样就支持在data-validation属性中使用json格式定义
1.修改metadata中属性初始化
metadata : {
defaults : {
type: 'attr',
name: 'data-validation',//修改原属性class为data-validation
cre: /({.*})/,
single: 'metadata'
},
setType: function( type, name ){
this.defaults.type = type;
this.defaults.name = name;
}
}
2.修改了这个后发现还是不能用，最后还要修改validation中的class定义
classRules: function(element) {
var rules = {};
var classes = $(element).attr('data-validation');//修改class为要定义的属性
if ( classes ) {
$.each(classes.split(' '), function() {
if (this in $.validator.classRuleSettings) {
$.extend(rules, $.validator.classRuleSettings[this]);
}
});
}
return rules;
},
==有些文档中讲到在文件尾部通过setType来设置，就可以实现，单在我这里并没有得到成功的结果。
$.metadata.setType("attr", "data-validation");
到这里 第一步完成可以实现在表单中通过扩展属性来书写验证规则
第二步：添加poshytip引用实现页面气泡提示效果
目的：完成对验证结果错误消息的接受并进行消息气泡形式显示
这里只添加引用还不行，需要对原版的JS和一些触发事件做一些修改才能完美实现我们想要的功能
<script src="~/plugs/poshytip/jquery.poshytip.js"></script>
<link href="~/plugs/poshytip/tip-twitter/tip-twitter.css" rel="stylesheet" />//样式也是必须要引入的，可以根据配置的皮肤选择引用样式文件
这里引用的jquery.poshytip.js是Poshy Tip jQuery plugin v1.0，针对JQuery1.9以上版本还存在一定的兼容问题出现以下异常
*$.browser这个api从jQuery1.9开始就正式废除，处理错误：Cannot read property ‘msie’ of undefined*/
为了兼容不同的jQuery版本我们需要在文件头加上这样一行代码就可以放心在各个jQuery版本下运行了
jQuery.browser = {}; (function () { jQuery.browser.msie = false; jQuery.browser.version = 0; if (navigator.userAgent.match(/MSIE ([0-9]+)./)) { jQuery.browser.msie = true; jQuery.browser.version = RegExp.$1; } })();
当然引入的样式文件要和配置文件里所配置的皮肤一致
poshytip配置：
$.fn.poshytip.defaults = {
content: '[title]', // content to display ('[title]', 'string', element, function(updateCallback){...}, jQuery)
className: 'tip-twitter', // class for the tips
bgImageFrameSize: 10, // 提示框背景图片的大小
showTimeout: 500, // timeout before showing the tip (in milliseconds 1000 == 1 second)
hideTimeout: 100, // timeout before hiding the tip
showOn: 'hover', // 触发何种事件显示提示框 ('hover', 'focus', 'none') - use 'none' to trigger it manually
alignTo: 'target', // 设置箭头位置('cursor', 'target')
alignX: 'right', // 水平对齐相对于鼠标光标或目标元素
// ('right', 'center', 'left', 'inner-left', 'inner-right') - 'inner-*' matter if alignTo:'target'
alignY: 'center', // 垂直对齐相对于鼠标光标或目标元素
// ('bottom', 'center', 'top', 'inner-bottom', 'inner-top') - 'inner-*' matter if alignTo:'target'
offsetX: 12, // 设置提示框横向偏移 - doesn't matter if alignX:'center'
offsetY: 18, // 设置提示框纵向偏移 - doesn't matter if alignY:'center'
allowTipHover: true, // 当鼠标悬在tip上时，不隐藏tip- matters only if showOn:'hover'
followCursor: false, //提示跟随光标移动- matters only if showOn:'hover' and alignTo:'cursor'
fade: true, // 使用fade动画
slide: true, // 使用slide动画
slideOffset: 8, // slide动画相抵消
showAniDuration: 300, // 显示动画时长 - set to 0 if you don't want show animation
hideAniDuration: 300, // 隐藏动画的持续时间 - set to 0 if you don't want hide animation
refreshAniDuration:1000 //异步更新提示时，动画的持续时间
};
从上边这些配置参数中，我们看到showOn属性有三个值的形式('hover', 'focus', 'none') ，但是这三个值对于原生poshytip来讲挺合理也够用了，但是我们现在需要在发生异常时显示tip的
错误提示，因此需要单独添加一个触发事件就可以解决问题。
这里我们加一个‘elemshow’用于在每个元素验证错误时弹出错误提示，最后一个触发事件为此次需要特别添加，并且制定提示框在3秒后自动消失。
switch (this.opts.showOn) {
case 'hover':
this.$elm.bind({
'mouseenter.poshytip': $.proxy(this.mouseenter, this),
'mouseleave.poshytip': $.proxy(this.mouseleave, this)
});
if (this.opts.alignTo == 'cursor')
this.$elm.bind('mousemove.poshytip', $.proxy(this.mousemove, this));
if (this.opts.allowTipHover)
this.$tip.hover($.proxy(this.clearTimeouts, this), $.proxy(this.hide, this));
break;
case 'focus':
this.$elm.bind({
'focus.poshytip': $.proxy(this.show, this),
'blur.poshytip': $.proxy(this.hide, this)
});
break;
//为指定元素tip提醒——刘自洋20160420
case 'elemshow':
this.showposition();
this.$tip.hover($.proxy(this.clearTimeouts, this), $.proxy(this.hide, this));
setTimeout($.proxy(this.hide, this),3000);
break;
}
到这里对poshytip和validate的改造就完成了，接下来我们考虑一下对于表单的验证，当鼠标离开文本框时或者键盘输入时都会用到验证，这里我们就要对validate的onfocusin,onfocusout
事件进行重写。
onfocusin: function (element) {
this.lastActive = element;
this.addWrapper(this.errorsFor(element)).hide();
var focusintip = $(element).attr('focusin');
if (focusintip && $(element).parent().children(".focusin").length === 0) {
//$(element).parent().poshytip({ content: focusintip, showOn: 'elemshow' });//tip光标选中后提示
}
// Hide error label and remove error class on focus if enabled
if (this.settings.focusCleanup) {
if (this.settings.unhighlight) {
this.settings.unhighlight.call(this, element, this.settings.errorClass, this.settings.validClass);
}
this.hideThese(this.errorsFor(element));
}
}
这里主要实现在用户选择输入框时给出填写提示，但是这东西很多时候也没啥必要，这里就注释掉了。
/*焦点离开*/
onfocusout: function (element) {
$(element).valid();
if ( !this.checkable( element ) && ( element.name in this.submitted || !this.optional( element ) ) ) {
this.element( element );
}
}
焦点离开时，给出验证并提示验证结果。
设置完触发事件并不能算完事，最重要的是要为错误提示指定显示位置和显示方式进行修改。
errorPlacement: function (error, element) {//错误信息显示位置
if ($(error).text() != "") {
$(element).poshytip({ content: $(error).text(), showOn: 'elemshow' });
//$(element).parent().poshytip({ content: $(error).text(), showOn: 'elemshow' });//父容器追加提示
}
}
通过前面定义的elemshow这里就派上用场了，错误信息展示。可以根据需要显示在当前目标元素为参照或者设置其父节点为参照。
至于显示位置不要忘了是通过poshytip的默认配置去调整。
第三步：开始验证
目的：为所有只要添加了data-validation标记并添加验证规则的表单做规则验证
为所有form表单添加验证，实现这一功能我们只需在全局js中添加以下代码就可实现。
/*指定表单加上验证才能提交*/
$(function () {
$("form").validate();
});
第四步：代码整理
上边说了这么多其实就是对这些插件的一些修改，看明白了意思就行。下面把各插件完整js奉上，可以直接放入项目应用。

这里的poshytip的皮肤文件不做任何修改，下载后可以直接引用，需要修改样式的单独修改poshytip对应皮肤文件吧。
--jquery.poshytip.js
--修改并添加对版本js的兼容
--为showOn添加elemshow可以在验证错误时显示错误消息提示。
/*
* 修改时间：2016-04-20
*修改人：Loyung
*说明：
*1.更新对JQuery9以上版本的兼容问题
*2.参数showOn添加"elemshow"，用作poshytip处理时使用。可以为任意元素创建showOn动作。

jquery.poshytip.js
我们自己重写定义的一些方法在这里比较综合，但也是结合validation和poshytip的关键。

/*修改默认validate提示信息*/

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"),
});
jquery.validate.tip.js
到这里已经基本算是完成了，后面会陆续优化一些bug。
疑难杂症分析：
1.如果提交表单时出现只验证第一个设置验证的元素，那么请检查标签是否配置了name属性或者配置了name属性相同了。
如果大家遇到哪些存在的bug都可以交流修改。
关于validation的具体详解对于新手来说可能好需要进一步了解，可以查看REX HE的博客 jQuery验证控件jquery.validate.js使用说明+中文API
