The "Progress Bar and Slider Widgets" Lesson is part of the full, jQuery Plugins and jQuery UI course featured in this preview video. Here's what you'd learn in this lesson:
This widget visually indicates progress status by setting the range using the “max” option and the “current value” (value option). There is a plan to make the progress support a false value, making this widget indeterminate for instances when the end value is not yet clear. Slider is useful whenever you need to input a number value and precision isn’t important. It can have single or multiple handles (ie: to input a range), highlighting the area between the two handles. The “orientation” option lets you display it vertically or horizontally and its “step” option lets you control the values for more granular inputs.
