Abstract

An electronic device includes processing circuitry; and a memory storing computer-executable instructions that cause the processing circuitry to instruct, by a web application operating in a web browser, a job executor to start executing a job by using a library; send a report of an execution state of the job executed by the job executor; and prevent a termination operation of terminating the web application that is displayed in the web browser, until the job instructed to start is terminated.

First claim

What is claimed is:

1. An electronic device comprising
a processor, and
a memory storing computer-executable instructions that cause the processor to:
instruct, by a web application operating in a web browser, a job executor to start executing a job by using a library;
send a report of an execution state of the job executed by the job executor; and
store menu non-display information in a storage provided in the electronic device, so as to prevent a termination operation of terminating the web application that is displayed in the web browser, until the job instructed to start is terminated, said processor storing the menu-non-display information after a start button is pressed by a user of the electronic device, and also after a parameter setting button is pressed before the start button is pressed,

wherein the processor prevents the termination operation of terminating the web application while the menu non-display information is stored in the storage.

2. The electronic device according to claim 1 , wherein the processor prevents the termination operation of terminating the web application that is displayed in the web browser, according to an instruction to prevent the termination operation given by the library, the library being instructed to prevent the termination operation by the web application.

3. The electronic device according to claim 1 , wherein the processor prevents the termination operation of terminating the web application that is displayed in the web browser, according to an instruction to prevent the termination operation given by the library, the library being instructed to start the job by the web application.

4. The electronic device according to claim 1 , wherein the processor prevents the termination operation of terminating the web application that is displayed in the web browser, according to an instruction to prevent the termination operation given by the web browser, the web browser being notified that the job has started by receiving the report.

5. The electronic device according to claim 1 , wherein the processor processing circuitry prevents the termination operation of terminating the web application, by not displaying a menu of the web application.

6. The electronic device according to claim 1 , wherein the processor prevents the termination operation of terminating the web application, by displaying a menu of the web application in a state such that an operation by a user cannot be accepted.

7. The electronic device according to claim 1 , wherein the processor prevents the termination operation of terminating the web application, by not displaying a button for accepting, from a user, an operation of displaying a menu of the web application.

8. The electronic device according to claim 1 , wherein the processor prevents the termination operation of terminating the web application, from when an operation to display a parameter setting screen of the web application is accepted from a user, to when the job instructed to start is terminated.

9. The electronic device according, to claim 1 , wherein the processor cancels the preventing of the termination operation of terminating the web application, upon detecting that cancellation of the job instructed to start is selected.

10. The electronic device according to claim 1 , wherein the processor stops a prevention of the termination operation of terminating the web application by storing menu display information in the storage.

11. An information processing system comprising:
a processor; and
a memory storing computer-executable instructions that cause the processor to:
instruct, by a web application operating in a web browser included in an information processing terminal, a job executor included in an electronic device to start executing a job by using a library;
send a report of an execution state of the job executed by the job executor; and
prevent a termination operation, of terminating the web application that is displayed in the web browser, until the job instructed to start is terminated by storing menu non-display information in a storage provided in the electronic device after a start button is pressed by a user of the electronic device, and also after a parameter setting button is pressed before the start button is pressed,

wherein the processor prevents the termination operation of terminating the web application while the menu non-display information is stored in the storage.

12. A method for preventing a termination operation, the method comprising:
instructing, by a web application operating in a web browser, a job executor included in an electronic device to start executing a job by using a library;
sending a report of an execution state of the job executed by the job executor; and
preventing the termination operation of terminating the web application that is displayed in the web browser, until the job instructed to start is terminated by storing menu non-display information in a storage provided in the electronic device after a start button is pressed by a user of the electronic device, and also after a parameter setting button is pressed before the start button is pressed,
wherein the preventing prevents the termination operation, of terminating the web application while the menu non-display information is stored in the storage.
