A very simple countdown timer

Requires jQuery

Just download countdown.js or countdown.min.js from dist dir and load it in your page.

First, create an element with data-time or data-seconds attribute (You can override attribute names through options if needded).

Like this:

<div class="timer" data-seconds="60">

The attribute provided specifies the behavior of countdown:

• data-time - Specify seconds from unix epoch.

  This mode counts down seconds till time specified is reached.

• data-seconds - Specify number of seconds to count down

  This mode counts down from specified amount of seconds till 0.

Note: Don't specify both attributes. If you do, the data-seconds attribute will be used.

And then just new-up the class, pass the elements and options if needed and You're done.

Like this:

// Let's query our elements
var elements = $('.timer');
// And start the countdown
new Countdown(elements, {initText: 'Please wait...'});

• endTimeAttr: (default: 'data-time')

  The attribute name to parse end time from.

• secondsAttr: (default: 'data-seconds')

  The attribute name to parse seconds from.

• dayTextAttr: (default: 'data-text')

  Attribute to parse day text from. Overrides daySingle option.

  Note: Use this attribute with usePlurals option disabled.

• useDayTextAttr: (default: true)

  Enable to use day text attribute. If disabled day text will be parsed from daySingle option.

• initText: (default: '---')

  Text to be displayed on the element while the first tick is hit.

• endedText: (default: '---')

  Text to be displayed on the element when the time is up.

• usePlurals: (default: false)

  Use plural text for days, hours, minutes and seconds. I.e. when seconds is 20 the text after will be parsed from secondPlural option, while if seconds is 1 - the text after will be parsed from secondSingle option and so on.

  If this option is disabled Countdown will use Single form for all texts (i.e. from option hourSingle for hours).

• showZeroDays: (default: true)

  Show or hide day portion of the output when days is 0.

• dayGenitive: (default: ' d. ')

  Text to be displayed after days portions of output when days count is more than 1 or i.e. 20 ("dienų" in lithuanian)

  Note: usePlurals must be enabled for this to work.
