Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, as a first aspect of the present invention, there is provided a Bootstrap-based custom workflow flow designer for rail transit, including a flow design unit, a flow preview unit, and a flow save unit; the flow design unit comprises a definition flow design control, a flow designer layout design control and a visual designer control;
The method comprises the steps of defining a workflow design control, wherein the workflow design control is specifically used for defining a graphic representation of each action in the workflow, and the workflow is provided with a set of graphic representations of each action, such as starting, ending, flow processing, branch selection and the like. And meanwhile, a tooltip component is used, so that friendly function prompts are popped up for each function component, and convenience is brought to users.
The flow designer layout design control is used for designing function buttons by adopting a dynamic floating toolbar.
The process designer is not only used at the computer end, but also used at the mobile end, the screen sizes of the computer end and the mobile end are different, and the width and the resolution are greatly different, so that the design layout needs to be elastically designed:
Computer terminal layout:
The computer end is arranged as equipment with the screen width larger than 768px, as shown in fig. 2, the screen of the equipment is larger, the function buttons of the designer can be displayed completely, and the top and the bottom can be arranged in a row respectively, the top is used for icons in the process such as start, end, branch judgment and the like, and the bottom is used for auxiliary functions such as icon alignment, icon connecting lines and the like.
The top uses BootStrap grid system, set to col-md-12 for the flow icon, occupy 12 columns, place navbar components that can be automatically folded at the mobile end, while the middle design panel, occupy 12 columns, 12 rows, and the right side auxiliary tools, occupy 12 columns, also place navbar components that can be automatically folded at the mobile end.
Layout of mobile terminal:
the mobile terminal is arranged as a device with a screen width smaller than 768px, as shown in fig. 3, the screen of such a device is smaller, and the width may be narrower, if the designer elements are all displayed, the blank panel of the designer may be squeezed to become smaller, and the blank panel cannot be used.
In order to solve the problems, the invention adopts a dynamic floating toolbar design, the toolbar floats to the top and the bottom, and meanwhile, a blank panel is designed into a rolling bar, so that the rolling bar can roll on a screen, but the position of the toolbar is not changed, and along with the rolling, the position of the toolbar is automatically adjusted and always kept in the top, middle and the bottom of the current screen; because the use of the mobile terminal is considered in the computer terminal layout, the mobile terminal only needs to add a rolling following function to the icon bar at the top and the auxiliary tool bar at the bottom of the computer terminal layout.
The mobile terminal can complete the design of one flow by using a plurality of scrolling screens.
The visual designer control is used for visually designing events and operations of the flow icons, establishing corresponding flow logic according to flow rules, generating corresponding flow data and loading the corresponding flow data into LocalStorage of the browser;
The visual designer control needs to realize the functions of flow icon drag and drop, flow icon positioning, flow icon connection, flow icon alignment and the like, and meanwhile needs to perform logic processing according to a series of flow rules, such as branch selection, and needs to connect more than two components; the start and end can only occur once, etc. The method comprises the steps of processing and monitoring events such as selection, clicking, movement and the like of a browser, and logically judging and processing by Javascript class of a system; in order to accelerate the rendering speed of the interface, the LocalStorage technology of the HTML5 is used for loading a part of data to LocalStorage of the browser, the data can be read from the direct browser during rendering, repeated reading from a server side is avoided, and meanwhile, the designer is still available under special conditions of network disconnection, network blocking and the like.
The user designs the flow design definition file generated by each operation and stores the flow design definition file into LocalStorage, so that the problem that the designed flow is lost due to careless closing or exiting of the user under special conditions is avoided.
The process preview unit acquires process data and dynamically generates the process data into an image which can be displayed on the current interface.
In the above embodiment, after the process design is completed, a canvas component of Javascript and HTML5 may be used to dynamically generate an image that can be displayed on the current interface according to the process data stored in LocalStorage, and then the starting graphic is read first, and then the subsequent processing graphic, the branch graphic, etc. are sequentially read, all the graphic objects are connected on the interface according to the sequence, using the connecting lines to form the complete process graphic, and using the automatic image scaling function of Bootstrap to adapt to the display of various screens, where the image can be displayed in the Windows system, the android system, and the apple operating system.
The graphic representation represents only the processing flow and has no relation with the attributes such as the size, position, color and the like of the image, so that the final flow definition file can be generated according to the flow data stored in LocalStorage as long as the sequence of the graphic representation, the connecting line of the graphic representation and the type of the graphic representation are not wrong in the previewed image.
The process saving unit is used for generating process definition Json files from the process data and uploading the process definition Json files to the server, wherein the process files represent final design processes, and start nodes of the processes, processing nodes of the processes, selection and end nodes of the processes and the like are defined in the process files, so that the processing sequence and processing logic of a service are represented.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
