在做系统时经常会用到数据校验，数据校验可以自己写，也可以用现在成的，现在记录下两种类库使用方法，
validator
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/html4/strict.dtd">

<!--加载jquery类-->
<script src="http://lib.sinaapp.com/js/jquery/1.7.2/jquery.min.js"></script>
<script>
if (!window.jQuery) {
var script = document.createElement('script');
script.src = "js/jquery-1.7.1.min.js";
document.body.appendChild(script);
}
</script>
<!--加载样式，可不加-->
<link rel="stylesheet" href="validator-0.7.0/jquery.validator.css">
<!--加载validator类-->
<script type="text/javascript" src="validator-0.7.0/jquery.validator.js"></script>
<script type="text/javascript" src="validator-0.7.0/local/zh_CN.js"></script>
</head>
<body style="background:#fff;">
<form role="form" action="user/updatesUser" enctype="multipart/form-data" method="post" validate="true" >
<input type="text" id="a" data-rule="required"/><br/>
<input type="text" id="b" data-rule="required ID_card"/><br/>
<input type="text" id="c" data-rule="required"/><br/>
<input type="text" id="d" data-rule="required email"/><br/>
<input type="text" id="e" data-rule="tel"/><br/>
<input type="text" id="f" data-rule="doubles"/><br/>
<input type="text" id="g" data-rule="digits"/><br/>
<input type="submit"/>
</form>
</body>
</html>
如要加新的校验类型只要在 zh_CN.js文件中添加正则表达式即可。
如下（部分代码）
rules: {
digits: [/^\d+$/, "请输入整数数字"]
,doubles:[/^[0-9]*[.]{0,1}[0-9]*$/,"请输入数字"]
,positiveinteger:[/^[1-9][0-9]*$/,"请输入正整数"]
,letters: [/^[a-z]+$/i, "{0}只能输入字母"]
,tel: [/^(?:(?:1[3-9]\d{9})|(?:0\d{2,3}[- ]?[1-9]\d{6,7})|(?:[48]00[- ]?[1-9]\d{6}))$/, "联系电话格式不正确"]
,mobile: [/^1[3-9]\d{9}$/, "手机号格式不正确"]
,email: [/^(?:[a-z0-9]+[_\-+.]?)*[a-z0-9]+@(?:([a-z0-9]+-?)*[a-z0-9]+\.)+([a-z]{2,})+$/i, "邮箱格式不正确"]
,qq: [/^[1-9]\d{4,}$/, "QQ号格式不正确"]
,date: [/^\d{4}-\d{1,2}-\d{1,2}$/, "请输入正确的日期,例:yyyy-mm-dd"]
,time: [/^([01]\d|2[0-3])(:[0-5]\d){1,2}$/, "请输入正确的时间,例:14:30或14:30:00"]
,ID_card: [/^[1-9]\d{5}[1-9]\d{3}((0\d)|(1[0-2]))(([0|1|2]\d)|3[0-1])((\d{4})|\d{3}[A-Z]|\d{3}[a-z])$/, "请输入正确的身份证号码"]
,url: [/^(https?|ftp):\/\/[^\s]+$/i, "网址格式不正确"]
,postcode: [/^[1-9]\d{5}$/, "邮政编码格式不正确"]
,chinese: [/^[\u0391-\uFFE5]+$/, "请输入中文"]
,contentsixty: [/^.[1-60]+$/, "不于大于60个字"]
,username: [/^\w{3,12}$/, "请输入3-12位数字、字母、下划线"]
,password: [/^[0-9a-zA-Z]{6,16}$/, "密码由6-16位数字、字母组成"]
,accept: function (element, params){
if (!params) return true;
var ext = params[0];
return (ext === '*') ||
(new RegExp(".(?:" + (ext || "png|jpg|jpeg|gif") + ")$", "i")).test(element.value) ||
this.renderMsg("只接受{1}后缀", ext.replace('|', ','));
}
}
});html代码如下
