JOS : Animation Library (v0.9.2)

Whats New :

• Added new Stagger Animations #25

  • Add the data-jos_stagger=animation_name attribute to the parent element along with jos class
  • data-jos_stagger_anchor=true would auto asign id for parent element & use it as a anchor for child elements.
  • data-jos_stagger_anchor=#id would use the given id as a anchor for child elements.
  • not using data-jos_stagger_anchor make the element independent of the parent element.
  • data-jos_stagger_seq is used to set the delay between each element in the sequence (to trigger one after other) whereas data-jos_stagger_delay total delay for each element as a whole.
  • learn more about staggering animation & its options here

JOS : Animation Library (v0.8.8)

Change Log

Description -

This version of JOS is a rewritten version based on the previous release, with numerous optimizations and a wealth of new features. The code has undergone significant improvements, including modularization, aimed at enhancing performance and providing useful features. We strive to deliver better performance and enhanced functionality with every update of JOS.

[v0.8.8] - 18/07/2023 -

• Fixed RootMargin calc bug (10% 10% 10% 10% would now be interpreted as 10% 10% -10% -10% automatically).

• Patched jos class forcing display:block;.

• Added jos-no-transition class to disable transition (must be added to class list).

• jos-animation now can be npm installed as a separate package.

  • jos-animation is now a separate package, which can be installed using npm i jos-animation.
  • still needs work to be done on the npm auto import, but it is functional.

• jos class now has lower priority over other user defined classes. (to ensure user can define their own classes without interference from jos)

  • due use !important to overide
  • define transition property specifically, exmaple : transition: opacity 0.5s ease-in-out, transform 0.5s ease-in-out;
  • You have to manually set transition property for custom animation classes, this is to ensure that jos transition property does not interfere with other transition properties for the element.

• Added new scrollCallback feature to get scroll progress.

  • scrollCallback is a function that is called on every scroll event.

  • returns element.jos as a parameter which contains all the jos data including scrollProgress.

  • an html element id is mandatory for this feature to work. So ensure that you have an id set for the element.

    • element.jos.windowScroll (gets scroll progress with respect to the entire window)
    • element.jos.rootScroll (gets scroll progress with respect to the root (rootMargin) of the element)
    • element.jos.scroll (same as rootScroll but values within 0 - 1)

  Exmaple -

  <!-- Scroller observer exmaple elements -->
  <div id="elem1" class="jos" data-jos_scroll="your_callbackFunction">
    Elemen 1
  </div>
  <div id="elem2" class="jos" data-jos_scroll="your_callbackFunction_2">
    Elemnt 2
  </div>
  <div id="elem3" class="jos" data-jos_scroll="your_callbackFunction_3">
    Elemnt 3
  </div>

  your_callbackFunction = (element) => {
    console.log(element.id, element.jos.scrollProgress);
    element.style.opacity = element.jos.scrollProgress;
  };
  
  your_callbackFunction_2 = (element) => {
    let percent = element.jos.windowScroll * 100 + "%";
    console.log(element.id, percent);
    element.style.width = percent;
  };
  
  your_callbackFunction_3 = (element) => {
    let deg = element.jos.rootScroll * 360 + "deg";
    console.log(element.id, deg);
    element.style.transform = deg;
  };

  Note -

  • scrollCallback is called on every scroll event, so it is recommended to use it only if required for better performance. (It is still better than other scroll event listeners as it uses IntersectionObserver API)

  • Scroll callback functions are called only if the element is in the viewport.

  • Custom Functions from demo/above example ( such as scrollWidth(), scrollOpacity(), scrollRotate(), etc) are not available with the package & are to be implemented by the user.

    • This is to ensure full customizability. (refer to the demo/example for implementation)

  • This feature leverages greater customizability & performance for the developer to implement complex animations without having to include other heavy resources.
