JQuery表单验证
jquery.validate.js 是 jquery 旗下的一个验证插件，借助 jquery 的优势，我们可以迅速验证一些常见的输入 , 并且可以自己扩充自己的验证方法。
举个例子，有这么一个表单：
view plaincopy to clipboardprint?
<form id="signupForm" method="get" action="">
<fieldset>
<legend>Validating a complete form</legend>
<p>
<label for="firstname">Firstname</label>
<input id="firstname" name="firstname" class="required"/>
</p>
<p>
<label for="lastname">Lastname</label>
<input id="lastname" name="lastname" />
</p>
<p>
<label for="username">Username</label>
<input id="username" name="username" />
</p>
<p>
<label for="password">Password</label>
<input id="password" name="password" type="password" />
</p>
<p>
<label for="confirm_password">Confirm password</label>
<input id="confirm_password" name="confirm_password" type="password" />
</p>
<p>
<label for="email">Email</label>
<input id="email" name="email" />
</p>
<p>
<input class="submit" type="submit" value="Submit"/>
</p>
</fieldset>
</form>
<form id="signupForm" method="get" action="">
<fieldset>
<legend>Validating a complete form</legend>
<p>
<label for="firstname">Firstname</label>
<input id="firstname" name="firstname" class="required"/>
</p>
<p>
<label for="lastname">Lastname</label>
<input id="lastname" name="lastname" />
</p>
<p>
<label for="username">Username</label>
<input id="username" name="username" />
</p>
<p>
<label for="password">Password</label>
<input id="password" name="password" type="password" />
</p>
<p>
<label for="confirm_password">Confirm password</label>
<input id="confirm_password" name="confirm_password" type="password" />
</p>
<p>
<label for="email">Email</label>
<input id="email" name="email" />
</p>
<p>
<input class="submit" type="submit" value="Submit"/>
</p>
</fieldset>
</form>
在这个表单中，有名、姓、用户名、密码、确认密码和 email 。他们都为非空，并且电子邮件需要是格式正确的地址、确认密码和密码一致。使用 jQuery 验证最简单的方式是引入 jquery.js 和 jquery validation.js 两个 js 文件。然后分别在 input 中加入 class 即：
view plaincopy to clipboardprint?
<input id="firstname" name="firstname" class="required"/>
<input id="lastname" name="lastname" class="required"/>
<input id="username" name="username" class="required"/>
<input id="password" name="password" type="password" class="required"/>
<input id="confirm_password" name="confirm_password" type="password" class="required" equalTo="#password"/>
<input id="email" name="email" class="required email"/>
<input id="firstname" name="firstname" class="required"/>
<input id="lastname" name="lastname" class="required"/>
<input id="username" name="username" class="required"/>
<input id="password" name="password" type="password" class="required"/>
<input id="confirm_password" name="confirm_password" type="password" class="required" equalTo="#password"/>
<input id="email" name="email" class="required email"/>
以下列出 validate 自带的默认验证
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: jQuery.format(" 请输入一个长度最多是 {0} 的字符串 "),
minlength: jQuery.format(" 请输入一个长度最少是 {0} 的字符串 "),
rangelength: jQuery.format(" 请输入一个长度介于 {0} 和 {1} 之间的字符串 "),
range: jQuery.format(" 请输入一个介于 {0} 和 {1} 之间的值 "),
max: jQuery.format(" 请输入一个最大为 {0} 的值 "),
min: jQuery.format(" 请输入一个最小为 {0} 的值 ")
然后，在 document 的 read 事件中，加入如下方法：
<script>
$(document).ready(function(){
$("#signupForm").validate();
}
</script>
这样，当 form 被提交的时候，就会根据 input 指定的 class 来进行验证了。如果失败， form 的提交就会被阻止。并且，将提示信息显示在 input 的后面。
不过，这样感觉不好，因为验证规则侵入了我们的 html 代码。还有一个方式，便是使用“ rules” 。我们将 input 的那些验证用 class 删除掉。然后修改 document 的 ready 事件响应代码：
$(document).ready(function(){
$("#signupForm").validate({
rules:{
firstname:"required",
lastname:"required",
username:"required",
password:"required",
confirm_password:{
required:true,
equalTo:"#password"
},
email:{
required:true,
email:true
}
}
});
})
这样以来，也能达到相同的效果。
那么，接下的问题，就是显示的错误提示是默认的。我们需要使用自定义的提示：
$(document).ready(function(){
$("#signupForm").validate({
rules:{
firstname:"required",
lastname:"required",
username:"required",
password:"required",
confirm_password:{
required:true,
equalTo:"#password"
},
email:{
required:true,
email:true
}
},
messages:{
firstname:" 必填项",
lastname:" 必填项",
username:" 必填项",
password:" 必填项",
confirm_password:{
required:" 必填项",
equalTo:" 密码不一致"
},
email:{
required:" 必填项",
email:" 格式有误"
}
}
});
})
如果你还想在错误信息上显示特别的样式 ( 比如字体为红色 ) 即可通过添加：
<style type="text/css">
#signupForm label.error {
padding-left: 16px;
margin-left: 2px;
color:red;
background: url(img/unchecked.gif) no-repeat 0px 0px;
}
</style>
继续添加对输入密码长度的验证规则：
$(document).ready(function(){
$("#signupForm").validate({
rules:{
firstname:"required",
lastname:"required",
username:"required",
password:{
required:true,
minlength:4,
maxlength:15
},
confirm_password:{
required:true,
equalTo:"#password"
},
email:{
required:true,
email:true
}
},
messages:{
firstname:" 必填项",
lastname:" 必填项",
username:" 必填项",
password:{
required:" 必填项",
minlength:jQuery.format(" 密码长度不少于 {0} 位 "),
maxlength:jQuery.format(" 密码长度不超过 {0} 位 ")
},
confirm_password:{
required:" 必填项",
equalTo:" 密码不一致"
},
email:{
required:" 必填项",
email:" 格式有误"
}
}
});
})
使用remote
可以通过 event 指定触发效验方式（ 可选值有 keyup( 每次按键时 ) ， blur( 当控件失去焦点时 ) ，不指定时就只在按提交按钮时触发 ）
$(document).ready(function(){
$("#signupForm").validate({
event:"keyup" || "blur"
})
})
如果通过指定 debug 为 true 则表单不会提交只能用来验证 ( 默认为提交 ) ，可用来调试
$(document).ready(function(){
$("#signupForm").validate({
debug:true
})
})
如果在提交前还需要进行一些自定义处理使用 submitHandler 参数
$(document).ready(function(){
$("#signupForm").validate({
SubmitHandler:function(){
alert( "success");
}
})
})

jquery.validate.js 是 jquery 旗下的一个验证插件，借助 jquery 的优势，我们可以迅速验证一些常见的输入 , 并且可以自己扩充自己的验证方法。
举个例子，有这么一个表单：
view plaincopy to clipboardprint?
<form id="signupForm" method="get" action="">
<fieldset>
<legend>Validating a complete form</legend>
<p>
<label for="firstname">Firstname</label>
<input id="firstname" name="firstname" class="required"/>
</p>
<p>
<label for="lastname">Lastname</label>
<input id="lastname" name="lastname" />
</p>
<p>
<label for="username">Username</label>
<input id="username" name="username" />
</p>
<p>
<label for="password">Password</label>
<input id="password" name="password" type="password" />
</p>
<p>
<label for="confirm_password">Confirm password</label>
<input id="confirm_password" name="confirm_password" type="password" />
</p>
<p>
<label for="email">Email</label>
<input id="email" name="email" />
</p>
<p>
<input class="submit" type="submit" value="Submit"/>
</p>
</fieldset>
</form>
<form id="signupForm" method="get" action="">
<fieldset>
<legend>Validating a complete form</legend>
<p>
<label for="firstname">Firstname</label>
<input id="firstname" name="firstname" class="required"/>
</p>
<p>
<label for="lastname">Lastname</label>
<input id="lastname" name="lastname" />
</p>
<p>
<label for="username">Username</label>
<input id="username" name="username" />
</p>
<p>
<label for="password">Password</label>
<input id="password" name="password" type="password" />
</p>
<p>
<label for="confirm_password">Confirm password</label>
<input id="confirm_password" name="confirm_password" type="password" />
</p>
<p>
<label for="email">Email</label>
<input id="email" name="email" />
</p>
<p>
<input class="submit" type="submit" value="Submit"/>
</p>
</fieldset>
</form>
在这个表单中，有名、姓、用户名、密码、确认密码和 email 。他们都为非空，并且电子邮件需要是格式正确的地址、确认密码和密码一致。使用 jQuery 验证最简单的方式是引入 jquery.js 和 jquery validation.js 两个 js 文件。然后分别在 input 中加入 class 即：
view plaincopy to clipboardprint?
<input id="firstname" name="firstname" class="required"/>
<input id="lastname" name="lastname" class="required"/>
<input id="username" name="username" class="required"/>
<input id="password" name="password" type="password" class="required"/>
<input id="confirm_password" name="confirm_password" type="password" class="required" equalTo="#password"/>
<input id="email" name="email" class="required email"/>
<input id="firstname" name="firstname" class="required"/>
<input id="lastname" name="lastname" class="required"/>
<input id="username" name="username" class="required"/>
<input id="password" name="password" type="password" class="required"/>
<input id="confirm_password" name="confirm_password" type="password" class="required" equalTo="#password"/>
<input id="email" name="email" class="required email"/>
以下列出 validate 自带的默认验证
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: jQuery.format(" 请输入一个长度最多是 {0} 的字符串 "),
minlength: jQuery.format(" 请输入一个长度最少是 {0} 的字符串 "),
rangelength: jQuery.format(" 请输入一个长度介于 {0} 和 {1} 之间的字符串 "),
range: jQuery.format(" 请输入一个介于 {0} 和 {1} 之间的值 "),
max: jQuery.format(" 请输入一个最大为 {0} 的值 "),
min: jQuery.format(" 请输入一个最小为 {0} 的值 ")
然后，在 document 的 read 事件中，加入如下方法：
<script>
$(document).ready(function(){
$("#signupForm").validate();
}
</script>
这样，当 form 被提交的时候，就会根据 input 指定的 class 来进行验证了。如果失败， form 的提交就会被阻止。并且，将提示信息显示在 input 的后面。
不过，这样感觉不好，因为验证规则侵入了我们的 html 代码。还有一个方式，便是使用“ rules” 。我们将 input 的那些验证用 class 删除掉。然后修改 document 的 ready 事件响应代码：
$(document).ready(function(){
$("#signupForm").validate({
rules:{
firstname:"required",
lastname:"required",
username:"required",
password:"required",
confirm_password:{
required:true,
equalTo:"#password"
},
email:{
required:true,
email:true
}
}
});
})
这样以来，也能达到相同的效果。
那么，接下的问题，就是显示的错误提示是默认的。我们需要使用自定义的提示：
$(document).ready(function(){
$("#signupForm").validate({
rules:{
firstname:"required",
lastname:"required",
username:"required",
password:"required",
confirm_password:{
required:true,
equalTo:"#password"
},
email:{
required:true,
email:true
}
},
messages:{
firstname:" 必填项",
lastname:" 必填项",
username:" 必填项",
password:" 必填项",
confirm_password:{
required:" 必填项",
equalTo:" 密码不一致"
},
email:{
required:" 必填项",
email:" 格式有误"
}
}
});
})
如果你还想在错误信息上显示特别的样式 ( 比如字体为红色 ) 即可通过添加：
<style type="text/css">
#signupForm label.error {
padding-left: 16px;
margin-left: 2px;
color:red;
background: url(img/unchecked.gif) no-repeat 0px 0px;
}
</style>
继续添加对输入密码长度的验证规则：
$(document).ready(function(){
$("#signupForm").validate({
rules:{
firstname:"required",
lastname:"required",
username:"required",
password:{
required:true,
minlength:4,
maxlength:15
},
confirm_password:{
required:true,
equalTo:"#password"
},
email:{
required:true,
email:true
}
},
messages:{
firstname:" 必填项",
lastname:" 必填项",
username:" 必填项",
password:{
required:" 必填项",
minlength:jQuery.format(" 密码长度不少于 {0} 位 "),
maxlength:jQuery.format(" 密码长度不超过 {0} 位 ")
},
confirm_password:{
required:" 必填项",
equalTo:" 密码不一致"
},
email:{
required:" 必填项",
email:" 格式有误"
}
}
});
})
使用remote
可以通过 event 指定触发效验方式（ 可选值有 keyup( 每次按键时 ) ， blur( 当控件失去焦点时 ) ，不指定时就只在按提交按钮时触发 ）
$(document).ready(function(){
$("#signupForm").validate({
event:"keyup" || "blur"
})
})
如果通过指定 debug 为 true 则表单不会提交只能用来验证 ( 默认为提交 ) ，可用来调试
$(document).ready(function(){
$("#signupForm").validate({
debug:true
})
})
如果在提交前还需要进行一些自定义处理使用 submitHandler 参数
$(document).ready(function(){
$("#signupForm").validate({
SubmitHandler:function(){
alert( "success");
}
})
})
