Options

Option	Type	Default	Description
animating_css_class	string	nst-animating	the css class to be used when the slider is to be animated (this happens when a certain min/max value is being set for example).
touch_tolerance_value_bar_x	number	15	the horizontal tolerance in pixels by which a handle of the slider should be grabbed if the user touches outside the slider bar area.
touch_tolerance_value_bar_y	number	30	the vertical tolerance in pixels by which a handle of the slider should be grabbed if the user touches outside the slider bar area.
left_grip_selector	string	.nst-slider-grip-left	the selector of the left grip handle. The left grip element must exist in the page when the slider is initialized.
right_grip_selector	string	undefined	the selector of the right grip handle. This is optional. A single handler bar is assumed if this selector is not specified.
value_bar_selector	string	undefined	the selector of the value bar. If not specified assumes a value bar representing the selection is not wanted.
rounding	object or number	1	the rounding for a certain value displayed on the slider. This rounds the values returned in the value_changed_callback as roundedValue : int(actualValue / rounding) * rounding. The rounding parameter can be a number (i.e., fixed rounding) or can depend on actualValue (i.e., dynamic rounding). To perform dynamic rounding an object must be passed instead of a value. For example, passing rounding : { '1' : '100', '10' : '1000', '50' : '10000' } will use rounding = 1 when actualValue <= 100, rounding = 10 when 100 < actualValue <= 1000 and so on...
crossable_handles	boolean	true	Allow handles to cross each other while one of them is being dragged. This option is ignored if just one handle is used.
value_changed_callback	function	function(cause, curMin, curMax, prevMin, prevMax) { return; }	a callback called whenever the user drags one of the handles.
user_mouseup_callback	function	function(vmin, vmax, left_grip_moved) { return; }	a callback called whenever the mouse button pressed while dragging a slider grip is released
user_drag_start_callback	function	function () { return; }	a callback called before the user drags one of the handles

Methods

When calling methods, use positional arguments. For example, for the set_position method, call:

$(".mySlider").nstSlider("set_position", 10 /* min */, 90 /* max */);

do not call:

$(".mySlider").nstSlider("set_position", { min: 10, max: 90 });

unless the documentation says that the first argument is an object.

Method	Arguments (positional)	Description
get_range_min	None	return the current minimum range of the slider
get_range_max	None	return the current maximum range of the slider
get_current_min_value	None	return the current minimum value of the slider
get_current_max_value	None	return the current maximum value of the slider
is_handle_to_left_extreme	None	return a boolean indicating whether or not the left handler is moved all the way to the left
is_handle_to_right_extreme	None	return a boolean indicating whether or not the right handler is moved all the way to the right

enable	None	enable the slider (i.e., user can move the handles)
is_enabled	None	return a boolean indicating whether or not the slider can be moved by the user
set_position	min: number, max: number	set the handles at the specified min and max values
set_step_histogram	histogram : array of numbers	use a non-linear step increment for the slider that is stretched where the histogram provided counts more items
unset_step_histogram	None	use a linear scale of increments for the slider
set_range	rangeMin : number, rangeMax : number	set the minimum and the maximum range of values the slider
set_rounding	rounding: number or object	set the rounding for the slider
get_rounding	None	return the current rounding of the slider
teardown	None	remove all data stored in the slider
