 Function: A pair of form labels under a multiple (including a) Form need to submit, use JS accurate to determine the current button on those elements to judge the use: Under the form label to find the current form of the container to give class= "form", the current form of the submit button to give class= "check" The element that needs to be validated as empty gives class= "Notnull" nullmsg= xx cannot be empty!
 "Hint, the form that needs to be logically judged gives the class=" need "the type of judgment that gives class=" num "(only a number) validation logicmsg=" XX can only be number "give class=" errormessage "Display error message Block Give class= "warn" Display error message does not use the JS object-oriented programming logic judgment, does not pass in the need identity, directly gives the regular expression attribute (custom) regex= "/^\d$/" to make the judgment in the exterior realization Global.submitcallback
