这篇文章主要介绍bootstrap-validator的使用示例，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
需要的js、css和img在下面都有说明，耐心点读！
需要的js文件: jquery.min.js，bootstrapValidator.min.js，bootstrap-validator-default.js（自定义的一个默认配置文件，是个人写的，非官方文件）
前两个文件cdn上都有，bootstrap-validator-default.js内容如下：
/*默认规则 start*///ip格式$.fn.bootstrapValidator.validators.ip = { //message: "ip格式不正确"
validate: function(validator, $field, options) { var value = $field.val(),

} return ipReg.test(value);
}
};//password格式$.fn.bootstrapValidator.validators.pw = { //message: "必须包含数字、英文字母、特殊字符"
validate: function(validator, $field, options) { var value = $field.val(),

} return true;
}
};//不允许有空格$.fn.bootstrapValidator.validators.noSpace = { //message: "必须包含数字、英文字母、特殊字符"
validate: function(validator, $field, options) { var value = $field.val(); if (typeof value != 'string' || value.indexOf(' ') > -1) { return false;
} return true;
}
};//网关格式$.fn.bootstrapValidator.validators.mask = { //message: "网关不可达"
validate: function(validator, $field, options) { var ipArr = $field.parent().parent().find('input[name="ip"]').val().split('.'),
gatewayArr = $field.parent().parent().find('input[name="gateway"]').val().split('.'),

len = 4,
i = 0; if (ipArr.length !== len || gatewayArr.length !== len || netmaskArr.length !== len) { return false;
} for (; i < len; i++) { if ((ipArr[i] & netmaskArr[i]) !== (gatewayArr[i] & netmaskArr[i])) { return false;
}
} return true;
}
};//邮箱 表单验证规则$.fn.bootstrapValidator.validators.mail = { //message: "邮箱格式不正确"

}
};//电话验证规则$.fn.bootstrapValidator.validators.phone = { //message: "0371-68787027"
validate: function(validator, $field, options) { var phone = /^0\d{2,3}-\d{7,8}$/,

}
};//区号验证规则$.fn.bootstrapValidator.validators.ac = { //message: "区号如：010或0371"
validate: function(validator, $field, options) { var ac = /^0\d{2,3}$/,

}
};//无区号电话验证规则$.fn.bootstrapValidator.validators.noactel = { //message: "电话格式如：68787027"
