【Flowchart Mode】What is a Flow Component
Abstract：This tutorial describes what a flow component is and how to use it.
The Flow Component is a set of programming modules used in ScrapeStorm Flowchart Mode, each component corresponding to an execution mode.
The process component consists of four:
Waiting, Loop, Judgment and End loop.
Components can be automatically generated by a click on a web page or manually dragged and dropped from the component window below. If you need to delete the component, just click the “X” in the upper right corner of the component to delete it.
Let’s take a closer look at each component.
The “Waiting” component is used for the timing wait process inserted between components.
For example, some web pages are slow to open. If you do not set the “Waiting” component, the results may be incomplete because some web page content is not loaded.
The default waiting time of the system is 1 second. You can set the waiting time according to your needs.
The “Loop” component is used to perform the operation of behavior component circularly. It can not be used alone and needs to be used in conjunction with the behavior component.
The “Loop” component added by the auxiliary click operation is complete and can be used directly by the user.
The “Loop” component that is dragged from the component window below is not complete. The dragged component contains only the “Loop Condition” subcomponent, and we need to drag in other behavior components to form a complete Loop component.
The “Judgment” component is used to conditionally perform the behavior of the behavior component, and like the “Loop” component, it cannot be used alone and needs to be used in conjunction with the behavior component.
The “Judgment” component added by the auxiliary click operation is complete and can be used directly by the user.
The “Judgment” component dragged from the component window below is not complete. The dragged component only contains the “Judgment condition” subcomponent, and we need to drag in other behavior components to form a complete “Judgment” component.

4. End loop
The “end loop” is usually nested inside the “loop” component to stop the current loop operation.
Normally, the Loop component loops through the task when the set loop condition is met until the loop condition ends.
If we want to end the loop ahead of time under certain conditions, we can set up a “Judgment” component and an “End loop” component.
