Want to use this effect without jQuery? We've got you covered with a pure JavaScript version!

initNovacancy('#no', {});

initNovacancy('#no', {
  'reblinkProbability': 0.1,
  'blinkMin': 0.2,
  'blinkMax': 0.6,
  'loopMin': 8,
  'loopMax': 10,
  'color': '#ffffff',
  'glow': ['0 0 80px #ffffff', '0 0 30px #008000', '0 0 6px #0000ff'],
  'off': 1,
  'blink': 1,
  'classOn': 'on',
  'classOff': 'off',
  'element': 'span', // 'data' is not a valid interactive element, use 'span' instead
  'autoOn': true
});

document.getElementById('no').dispatchEvent(new CustomEvent('blinkOn'));

document.getElementById('no').dispatchEvent(new CustomEvent('blinkOff'));

The vanilla version returns an array of Novacancy instances, allowing more control:

// Initialize and store instances
const instances = initNovacancy('.neon-text', options);

// Update options after initialization
instances[0].setOptions({
  'color': 'GREEN',
  'glow': ['0 0 80px GREEN', '0 0 30px LIME', '0 0 6px #AAFF00']
});

// Clean up resources when no longer needed
instances[0].destroy();
