var aUsage = { "int":"^([+-]?)//d+$", "int+":"^([+]?)//d+$", "int-":"^-//d+$", "num":"^([+-]?)//d*//.?//d+$", "num+":"^([+]?)//d*//.?//d+$", "num-":"^-//d*//.?//d+$", "float":"^([+-]?)//d*//.//d+$", "float+":"^([+]?)//d*//.//d+$", "float-":"^-//d*//.//d+$", "email":"^//w+((-//w+)|(//.//w+))*//@[A-Za-z0-9]+((//.|-)[A-Za-z0-9]+)*//.[A-Za-z0-9]+$", "color":"^#[a-fA-F0-9]{6}", "url":"^http[s]?://////([//w-]+//.)+[//w-]+([//w-./?%&=]*)?$", "chinese":"^[//u4E00-//u9FA5//uF900-//uFA2D]+$", "ascii":"^[//x00-//xFF]+$", "zipcode":"^//d{6}$", "mobile":"^0{0,1}13[0-9]{9}$", "ip4":"^/(([0-1]?//d{0,2})|(2[0-5]{0,2}))//.(([0-1]?//d{0,2})|(2[0-5]{0,2}))//.(([0-1]?//d{0,2})|(2[0-5]{0,2}))//.(([0-1]?//d{0,2})|(2[0-5]{0,2}))$", "notempty":"^[^ ]+$", "picture":"(.*)//.(jpg|bmp|gif|ico|pcx|jpeg|tif|png|raw|tga)$", "rar":"(.*)//.(rar|zip|7zip|tgz)$", "date":"^//d{4}(//-|///|/.)//d{1,2}//1//d{1,2}$" };
