progress

progress tag defines the progress (process) of a running task.

Properties

Properties	Value	Description
max	number	Specifies the maximum value to be accomplished
value	number	Specifies the current value of the process
position	float	ReturnProgress bar 's current position
labels	-	Returns the progress bar's label list (if any)

maxThe default progress value range is from 0.0~1.0, if set to max=100 , then the progress value range is from 0~100.
##value specifies the current value, if max=100 ,value=50, then the progress is exactly half. The existence of the value attribute determines whether the progress progress bar has determinism. When When there is no value, the browser progress bar will loop infinitely. However, once there is a value attribute (even if there is no value), it is considered to be certain.
position is a read-only attribute, which reflects the current progress position, which is the value of value/max.
labels is also a read-only attribute, and what is obtained is the label elements pointing to the progress element.
