jqueryvalidation 常用插件 *代表php暂时不支持 required:true 必须输入的字段。 remote:"check.php" 使用 ajax 方法调用 check.php 验证输入值。 email:true 必须输入正确格式的电子邮件。 url:true 必须输入正确格式的网址。 date:true 必须输入正确格式的日期。日期校验 ie6 出错,慎用。 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。 *** number:true 必须输入合法的数字(负数,小数)。 digits:true 必须输入整数。 creditcard: 必须输入合法的信用卡号。 *** equalTo:"#field" 输入值必须和 #field 相同。 *** accept: 输入拥有合法后缀名的字符串(上传文件的后缀)。 maxlength:5 输入长度最多是 5 的字符串(汉字算一个字符)。 minlength:10 输入长度最小是 10 的字符串(汉字算一个字符)。 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)。 range:[5,10] 输入值必须介于 5 和 10 之间。 max:5 输入值不能大于 5。 min:10 输入值不能小于 10。
