Abstract

The invention provides an Angular-based flow chart editor implementation method, belongs to the technical field of computers, and aims to establish graphical flow chart editing of real-time response of nodes and connection flow lines through mouse dragging. According to a flow chart editor, the angular framework is used, modular components are used, module splitting of the flow chart editor is achieved, and the coupling of codes is reduced; the draggable node assembly is utilized, so that nodes are created by dragging from the toolbar to any position point of the canvas, the interactivity of the flow chart editor is enhanced, and the experience effect is optimized; bidirectional data binding of angular is utilized, dom operation is reduced, and the response efficiency of the flow chart editor is improved; the node information is stored after being orderly processed, so that the subsequent flow chart data design process is facilitated.

Description

technical field [0001] The invention relates to computer technology, in particular to an Angular-based flow chart editor implementation method. Background technique [0002] The flow chart editor developed based on the native javascript and using the ES5 standard has problems such as poor compatibility, high coupling, and high redundancy, and there are many inconveniences in implementation, operation and maintenance, and reuse. The Angular framework has features such as modularity, MVC, dependency injection, semantic tags, two-way data binding, and typescript object-oriented programming; dependency injection, semantic tags, object-oriented programming, etc. make it more readable, while modules Modernization and MVC make the development more efficient and have good reconfiguration, which is convenient for later maintenance and reuse. [0003] The existing system uses the click method to create nodes, which has poor interactivity, the flow chart drawing process is rigid, and ...
