As a kind of improvement project of input system, also on interface, show exercise question switching push button in described functional control module, during click exercise question switching push button, other exercise questions in database are presented in operation display window by exercise question display module.
As a kind of improvement project of input system, answer code module shows the content regenerated in code frame.
An input method for special character, comprises the steps:
Building database, stores special character in database, and each special character all has the unique string mated with it;
Exercise question is presented in operation display window by exercise question display module, and student's editor module shows editor on interface, and special character module shows all types of special character buttons that can be clicked on interface;
Input answer in the editing window, click corresponding special character button when typing special character, show corresponding special character picture or content in editor thereupon, in code frame, show the unique string of coupling;
Answer code module regenerates the content inputted in editor, and special character is wherein replaced by the character string of mating with it;
Click on submission button, the content in answer code module stores by functional control module again.
As a kind of improvement project of input method, when described answer code module regenerates input content, it is shown in code frame.
Compared with prior art, the present invention can realize the input of special character without the need to any formula editors, the input step of student is enormously simplify by special character button, input speed and fast response time, storage code is few, save storage space, improve operational efficiency, and lay the foundation for system is corrected further to the answer of student.
