Display control information generation
View Patent ↗Provides a Web server for generating display control information for dividing and displaying a form in a style conforming to a client device used by a user, which includes a HTTP request reception unit for receiving a form request from the client device, an application code database for storing a screen definition of the form subjected to the form request and a code of a validator for executing validation of an input value inputted into an input item in the form, a form division unit for dividing the form in conformity to the acquired terminal capacity by use of the read-out screen definition of the form and the read-out code of the validator, and a screen generation unit for generating screen information to be displayed on the client device by use of a result of division.
1. A display control information generation method comprising:
using an input/output device receiving a request for a form from a terminal used by a user, said form comprising input fields to be populated with input values supplied by said user;
using a processor device for:
acquiring a terminal capacity of the terminal transmitting the form request;
initializing an internal state of a web page;
dividing the form in conformity to the acquired terminal capacity by use of a read-out screen definition of the form and read-out validators in order to generate sub-form pages, wherein the dividing step comprises steps of:
deriving a reference relation between the validators and input items;
grouping the input items into input item groups in the sub-form pages to categorize an input item of the input items referenced by a same validator in a same input item group such that input fields to be referenced by one validator do not belong to two or more divided forms; and
dividing the input item groups into sizes not exceeding a predetermined size determined by the terminal capacity;
for any groups that exceed the pre-determined size, performing:
selecting one of the groups exceeding the pre-determined size;
within the selected group, identifying the input items referenced by two or more validators in said selected group;
selecting the input item referenced by the most validators from the input items referenced by two or more validators;
copying the selected input item in duplicate; and
modifying the reference relation to reference an original field and a copied field by different validators independently;
using the input/output device for transmitting the sub-form pages obtained by division to the terminal;
in response to the transmission, receiving a processing request from the terminal, said processing request comprising values of input items in the sub-form pages, and any determination of navigation processing to a different sub-form page;
retrieving the validators corresponding to the input items;
validating input values according to the retrieved validators and the navigation processing; and
updating the internal state of the web page using the validated input values.
2. The display control information generation method according to claim 1 , further comprising:
a division adjustment step of adjusting the groups, in terms of the groups obtained by grouping in the dividing step, so as to allow a result obtained by merging all adjacent groups to exceed the terminal capacity.
3. The display control information generation method according to claim 1 , further comprising the step of:
generating a user interface for acquiring an input for an input item of the sub-form by a user, and for indicating the status of the validator having a reference relation with the input item to the user.
4. A computer program product embodied on a computer readable recording medium, and enabling a computer to perform steps of:
receiving a request for a form from a terminal used by a user, said form comprising input fields to be populated with input values supplied by said user;
acquiring a terminal capacity of the terminal transmitting the form request;
initializing an internal state of a web page;
dividing the form in conformity to the acquired terminal capacity by use of a read-out screen definition of the form and read-out validators in order to generate sub-form pages, wherein the dividing step comprises steps of:
deriving a reference relation between the validators and input items;
grouping the input items into input item groups in the sub-form pages to categorize an input item of the input items referenced by a same validator in a same input item group such that input fields to be referenced by one validator do not belong to two or more divided forms; and
dividing the input item groups into sizes not exceeding a predetermined size determined by the terminal capacity;
for any groups that exceed the pre-determined size, performing:
selecting one of the groups exceeding the pre-determined size;
within the selected group, identifying the input items referenced by two or more validators in said selected group;
selecting the input item referenced by the most validators from the input items referenced by two or more validators;
copying the selected input item in duplicate; and
modifying the reference relation to reference an original field and a copied field by different validators independently;
transmitting the sub-form pages obtained by division to the terminal;
in response to the transmission, receiving a processing request from the terminal, said processing request comprising values of input items in the sub-form pages, and any determination of navigation processing to a different sub-form page;
retrieving the validators corresponding to the input items;
validating input values according to the retrieved validators and the navigation processing; and
updating the internal state of the web page using the validated input values.
