bootstrap-validator使用详解
2019年11月30日
作者：佚名
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){varvalue=$field.val(),
ipReg=/^(?:25[0-5]|2[0-4]d|1d{2}|[1-9]?d).(?:25[0-5]|2[0-4]d|1d{2}|[1-9]?d).(?:25[0-5]|2[0-4]d|1d{2}|[1-9]?d).(?:25[0-5]|2[0-4]d|1d{2}|[1-9]?d)$/;if(value===''){returntrue;
}returnipReg.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){varvalue=$field.val(),
ipReg=/.*(?=.*d)(?=.*[a-zA-Z])(?=.*[~!@#$%^&*_])./;
if(typeofvalue!='string'||!ipReg.test(value)){returnfalse;
}returntrue;
}
};//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){varvalue=$field.val();if(typeofvalue!='string'||value.indexOf('')>-1){returnfalse;
}returntrue;
}
};//网关格式$.fn.bootstrapValidator.validators.mask={//message:"网关不可达"
validate:function(validator,$field,options){varipArr=$field.parent().parent().find('input[name="ip"]').val().split('.'),
gatewayArr=$field.parent().parent().find('input[name="gateway"]').val().split('.'),
value=$field.val(),
netmaskArr=value.split('.'),
len=4,
i=0;if(ipArr.length!==len||gatewayArr.length!==len||netmaskArr.length!==len){returnfalse;
}for(;i<len;i++){if((ipArr[i]&netmaskArr[i])!==(gatewayArr[i]&netmaskArr[i])){returnfalse;
}
}returntrue;
}
};//邮箱表单验证规则$.fn.bootstrapValidator.validators.mail={//message:"邮箱格式不正确"
validate:function(validator,$field,options){varmail=/^[a-z0-9._%-]+@([a-z0-9-]+.)+[a-z]{2,4}$/,
value=$field.val();returnmail.test(value);
}
};//电话验证规则$.fn.bootstrapValidator.validators.phone={//message:"0371-68787027"
validate:function(validator,$field,options){varphone=/^0d{2,3}-d{7,8}$/,
value=$field.val();returnphone.test(value);
}
};//区号验证规则$.fn.bootstrapValidator.validators.ac={//message:"区号如：010或0371"
validate:function(validator,$field,options){varac=/^0d{2,3}$/,
value=$field.val();returnac.test(value);
}
};//无区号电话验证规则$.fn.bootstrapValidator.validators.noactel={//message:"电话格式如：68787027"
