This paper introduces an interactive enhancement system for industrial control flowcharts based on JavaScript,aiming to reduce the implementation difficulty of complex interaction logic in flowcharts.In the field of industrial control,tra-ditional flowchart tools rely on predefined specifications and interface operations for graphical drawing and parameter config-uration,which limits their flexibility and scalability when dealing with complex conditional statements and operational flows.To address these issues,this system utilizes JavaScript technology to extend the interactivity and functionality of flowcharts.
