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:

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 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"; },
        ]
    }
})
