The java language operates normally in the x86 environment, but the Loongson CPU is based on the MIPS instruction set, so that the java version in the x86 environment cannot operate normally in the Loongson CPU environment, and a list designer is required to be opened based on the java version OpenJDK to enable the Java version to operate normally in the Loongson environment.

In one embodiment of the invention, the form designer has editing and typesetting functions, can design electronic forms in rich formats by means of mouse dragging, seeing and obtaining, and provides binding support functions for data sources. The form designer mainly comprises functions of control library management, form attribute and behavior definition, form layout design, form data verification definition, form field association/sub-form management, form control behavior management, event script definition and the like.

Function 1: control library management: and is mainly responsible for loading the control library according to the configuration file. The control library currently supports the following 14 common form controls: labels, multi-line text blocks, single-line text boxes, buttons, check boxes, radio boxes, drop-down boxes, date controls, tree controls, graphic control groups (lines, rectangular boxes, etc.), attachment control groups (single-field attachments, multi-record attachments), office groups (supporting documents such as Word, excel, powerPoint, WPS, etc.), picture controls, audit opinion fields.

Function 2: form attributes and behavior definitions: the method is mainly responsible for processing the definition of events such as the own attribute of the form, the form initialization, the template loading, the data checking, the data saving and the like.

Function 3: form layout design: the electronic form with rich format can be designed by means of mouse dragging and what you see is what you get.

Function 4: form control attribute definition: is mainly responsible for defining the extrinsic properties of the control.

Function 5: form data validation definition: defining rules requiring verification of fields supports not only regular expressions and some common verification rules built-in to the system, but also comparison of values between fields in complex situations.

Function 6: form field association/sub-form management: the association information between tables/forms, i.e., the primary key foreign key information, is defined.

Function 7: form control behavior definition: and the control value is mainly responsible for processing other edit box events caused by the change of the control value, such as linkage drop-down boxes, values returned from the selected value and assigned to other field edit boxes, hidden states of the other field edit boxes and the like.

Function 8: event script definition: the most popular scripting languages, such as Java Script or VB Script, are supported. Scripts for electronic forms are divided into two categories, global scripts and "event" based scripts. Global scripts refer to variables, functions, and code that can be used within the context of the current form page. "event" based scripts refer to programs driven by the corresponding form component, such as: when the form designer is used for designing button pressing control functions, many functions (complex data calculation, data verification and the like) of the form designer can be completed without simply defining a form, and some script programs are required to be written to achieve the purpose.

Form controls are the basic elements that implement the functionality of an electronic form designer. Two categories can be distinguished depending on the purpose of the control: non-data controls and data controls. The actions of the non-data controls include beautifying the document, providing entry cues to the data controls, and the like. The role of the data control includes binding the data to the table field relationship and submitting the data to the control associated fields and tables.

The form control mainly comprises three parts of attribute management, event management and verification management:

1. attribute management: consists of two parts, namely a display attribute and a data attribute. The display attribute is the external expression information of the control, including the font color, size, direction, position and other contents of the control. The data attribute is information such as a data table and a field associated with the control, a main foreign key of the data table, a source table and a field of the data item, and the like.

2. Event management: events generated by controlling the triggering actions of the mouse and the keyboard or events generated by changing the control values. For example: what actions need to be done when the mouse is clicked, and what actions need to be done when the control value changes.

3. And (3) checking and managing: and setting filling-in check rules for the control values, wherein the filling-in check rules can be regular expression check or common check (numerical value, normal character, mail, mobile phone number, amount and the like). The check rule is used for judging whether the filled contents are valid or not before the form data are submitted.

It should be noted that, for simplicity of description, the foregoing method embodiments are all described as a series of acts, but it should be understood by those skilled in the art that the present invention is not limited by the order of acts described, as some steps may be performed in other orders or concurrently in accordance with the present invention.

Fig. 9 shows a schematic block diagram of an electronic device that may be used to implement an embodiment of the invention. As shown, the device 900 includes a loongson CPU901 that can perform various suitable actions and processes in accordance with computer program instructions stored in a Read Only Memory (ROM) 902 or loaded from a storage unit 908 into a Random Access Memory (RAM) 903. In (RAM) 903, various programs and data required for the operation of the electronic device 900 can also be stored. Loongson CPU901, ROM 902, and RAM 903 are connected to each other via bus 904. An input/output (I/O) interface 905 is also connected to the bus 904.

Various components in device 900 are connected to I/O interface 905, including: an input unit 906 such as a keyboard, a mouse, or the like; an output unit 907 such as various types of displays, speakers, and the like; a storage unit 908 such as a magnetic disk, an optical disk, or the like; and a communication unit 909 such as a network card, modem, wireless communication transceiver, or the like. The communication unit 909 allows the device 900 to exchange information/data with other devices through a computer network such as the internet and/or various telecommunications networks.

The processing unit 901 performs the respective methods and processes described above, for example, the methods S100, S200, S300. For example, in some embodiments, the methods S100, S200, S300 may be implemented as a computer software program tangibly embodied on a machine-readable medium, such as the storage unit 908. In some embodiments, part or all of the computer program may be loaded and/or installed onto the device 900 via the ROM 902 and/or the communication unit 909. When the computer program is loaded into (RAM) 903 and executed by CPU901, one or more steps of the methods S100, S200, S300 described above may be performed. Alternatively, in other embodiments, loongson CPU901 may be configured to perform methods S100, S200, S300 by any other suitable means (e.g., by means of firmware).

The functions described above herein may be performed, at least in part, by one or more hardware logic components. For example, without limitation, exemplary types of hardware logic components that may be used include: a Field Programmable Gate Array (FPGA), an Application Specific Integrated Circuit (ASIC), an Application Specific Standard Product (ASSP), a system on a chip (SOC), a load programmable logic device (CPLD), etc.

Program code for carrying out methods of the present invention may be written in any combination of one or more programming languages. These program code may be provided to a processor or controller of a computer, special purpose computer, or other programmable data processing apparatus that loads the Loongson CPU, such that the program code, when executed by the processor or controller, causes the functions/operations specified in the flowchart and/or block diagram to be implemented. The program code may execute entirely on the machine, partly on the machine, as a stand-alone software package, partly on the machine and partly on a remote machine or entirely on the remote machine or server.

In the context of the present invention, a machine-readable medium may be a tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device. The machine-readable medium may be a machine-readable signal medium or a machine-readable storage medium. The machine-readable medium may include, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

Moreover, although operations are depicted in a particular order, this should be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In certain circumstances, multitasking and parallel processing may be advantageous. Likewise, while several specific implementation details are included in the above discussion, these should not be construed as limiting the scope of the invention. Certain features that are described in the context of separate embodiments can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable subcombination.

Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above. Rather, the specific features and acts described above are example forms of implementing the claims.
