Examples

There are some example usages that you can look at to get started. They can be found in the examples folder.

Options

rangeslide.js can accept an options object to alter the way it looks and behaves. If no options object is passed default values are used. The example of a structure of an options object is as follows:

{
  data: [
  	{ name: "example1", item: "Example text" },
  	{ name: "example2", item: "Another example text" },
  	{ name: "example3", item: function() { return "And yet another example text"; }
  ],
  showLabels: true,
  showTicks: true,
  labelsPosition: "alternate",
  startAlternateLabelsFromTop: true,
  startPosition: 0,
  thumbHeight: 16,
  thumbWidth: 16,
  handlers: {
    initialized: function(rangeslideElement) {},
    valueChanged: function(data, rangeslideElement) {},
    markerClicked: function(data, markerElement) {}
  }

Here is the explanation of options object:

Option	Type	Description	Default	Options
autoPlay	Boolean	Enable auto play mode	false
autoPlayDelay	Number	Delay (in miliseconds) between steps in auto play mode	1000
data	Array	Array of data objects (property 'name' is mandatory	[]
enableLabelClick	Boolean	Enable click on labels	true
enableMarkerClick	Boolean	Enable click on track markers	true
enableTrackClick	Boolean	Enable click on track	true
handlers	Object	Event handlers collection	{}
highlightSelectedLabels	Boolean	Enable highlighting of selected labels	false
labelsPosition	String	Position of labels on a rangeslide	'below'	'above', 'below', 'alternate'
labelsWidth	Number	Width of labels	60
leftLabel	String	Text to display on left side label	""
loop	Boolean	Enable loop when auto play mode is active	true
markerSize	Number	Size of track marker (pixels)	14
rightLabel	String	Text to display on right side label	""
showLabels	Boolean	Show/hide labels	false
sideLabelsWidth	Number	Width of left and right side labels	40
showTrackMarkersProgress	Boolean	Indicate progress on markers	false
showTicks	Boolean	Show/hide label ticks	false
showTrackMarkers	Boolean	Show/hide track markers	false
showTrackProgress	Boolean	Indicate progress on track	false
showValue	Boolean	Show/hide value indicator	false
startAlternateLabelsFromTop	Boolean	Show first label above if labelsPosition is 'alternate'	false
startPosition	Number	Initial position of rangeslide thumb	0
stepSize	Number	Size of rangeslider step	16
thumbHeight	Number	Height of thumb element (in pixels)	16
thumbWidth	Number	Width of thumb element (in pixels)	16
tickHeight	Number	Height of label's tick (in pixels)	16
trackHeight	Number	Height of rangeslide track (in pixels)	7
valueIndicatorOffset	Number	Value indicator offset from rangeslider thumb	5
valueIndicatorWidth	Number	Width of value indicator (in pixels)	32
valueIndicatorHeight	Number	Height of value indicator (in pixels)	32
valuePosition	String	Position of value indicator	'thumb'	'above', 'below', 'thumb'
valueSource	String	Source of data for value indicator	'index'	'index', 'name', 'item'

Data

Data collection for rangeslide is provided during instatiation or later using "data" attribute in options. Number of steps (markers) for a slider is equal to number of items passed in this attribute. Each data item is required to have at least "name" attribute (String). You can also pass additional data using "item" attribute. Below is an example of proper data setup:

rangeslide("#element" {
	data: [
    	{ name: "data1", item: "simple string data"},
        { name: "data2", item: ["data", "in", "a", "form", "of ", "an", "array"] },
        { name: "data3", item: function() { return "data in a form of a function"; } },
        { name: "data4", item: { "passing": "object", "as": "data" } },
        { name: "data5" }
    ]
})

Rangeslide constructed with the above data will have 3 steps (markers).

Methods

Methods are called on rangeslide instances. You shoud save the instances to variable to have further access to it.

Object getValue()

Get current rangeslide value.

var item = rangeslide.getValue();

DOMNode getElement()

Gets rangeslide's DOM node object.

var node = rangeslide.getElement();

void setValue(Number index)

Set rangeslide value by specifying data index.

rangeslide.setValue(2);

void setValueByName(String name)

Set rangeslide value by specifying data name. If multiple data items with the same names are found first one is set.

rangeslide.setValueByName("exampleName");

void setOption(String name, Object value)

Gets rangeslide's DOM node object.

rangeslide.setOption("autoPlay", true);

void refresh()

Manually refresh and redraw rangeslide. Invoked automatically when options change.

rangeslide.refresh();

Events

rangeslide.js provides custom events for some of it's actions. Appropriate callbacks can be specified in options.

Event	Description	Arguments
valueChanged	Fires after slider value is changed	dataItem, rangeslideElement
playStart	Fires when auto play is started	dataItem, rangeslideElement
playStop	Fires when auto play is stopped	dataItem, rangeslideElement
initialized	Fires after slider is initialized	rangeslideElement
refreshed	Fires after slider is refreshed	rangeslideElement
trackClicked	Fires after slider track is clicked	dataItem, trackElement
labelClicked	Fires after label is clicked	dataItem, labelElement
markerClicked	Fires after track marker is clicked	dataItem, markerElement
thumbDragStart	Fires when thumb dragging is initiated	dataItem, thumbElement
thumbDragged	Fires when thumb is being dragged	dataItem, thumbElement
thumbDraggedEnd	Fires when thumb is dropped	dataItem, thumbElement

Event handlers are passed in rangeslide options like in the example below:

rangeslide("#element" {
	handlers: {
    	"valueChanged": [function(data, element) { console.log(data); }],
        "labelClicked": [
        	function(data, element) { console.log(data); },
            function(data, element) { return data.name; },
            function(data, element) { element.style.backroundColor = "#e2e3e4"; },
        ]
    }
})
