3. if you want to validate the relationship between two fields, you should provide the methods by yourself. the validate.js will provide the method to define the error message and some methods to help you do that, such as constructdate, commonvalidatenumberr. if self defined validation is used in several jsps, you can put these validations into commonvalidation.js file. here is the method lists:
methods used to process error:
1) errorprocess(errorfield, errormessage)
description: write the errormessage in the specified division by yourself and tell user which field data is invalid;
parameters: errorfield — the name of error elements, you can pass one element name, or a array of element name;
errormessage — the displayed message;
return: void;
example: show as below;
2) checkerror(form)
description: check the array which contains the error fields, if the array is empty,
return true, else return false;
parameters: form — the name of form;
return: true or false;
example:show as below;
methods used to help you apply self defined validation rules:
1) commonvalidatenumberr(field,lb,ub)
description: valid integers within specified bounds;
parameters: field — the data you wanna validate
lb — the minimum number
ub — the maximum number;
return: true or false;
example: commonvalidatenumberr(hour,0,23), if hour < 0 or hour > 23, return false, else return ture;
2) constructdate(dayobj,monthobj,yearobj)
description: construct the date obj according the input field data;
