new Process(step, contextopt)
A Process is a list of steps that are called in sequence. The step can be a number, a jQuery promise, or a function:
- number: the process will wait for the specified number of milliseconds before proceeding.
- promise: the process will continue to the next step when the promise is successfully resolved or stop if the promise is rejected.
- function: the process will execute the function. The process will stop if the function returns
either a boolean
falseor a promise that is rejected; if the function returns a number, the process will wait for that number of milliseconds before proceeding.
If the process fails, an error is generated. Depending on how the error is configured, users can dismiss the error and try the process again, or not. If a process is stopped, its remaining steps will not be performed.
