Parameters

Returns

This function does not return a value.

Usage

The cfprogressbar tag creates the HTML markup; at runtime, you use this function to initiate the progress bar object. On initialization, ColdFusion calls the underlying CFC, which is defined using a bind expression, at specified intervals. The CFC returns the progress status, which is passed to the underlying Ext progress bar object to update the progress bar value. The progress status object that the CFC returns must have STATUS and MESSAGE properties. The STATUS property has a numeric value from 0.0 to 1.0.
