Sorry if i post again, but it could be usefull for others, i guess.
After restarting from the ground. I managed to activate a part of "the play on viewport" function.
When imported in the HTML the OAM files create a folder Asset with inside the animation in an html page.
In this page, inside the animation script, i added 2 functions :
// TRIGGER THE FUNCTION WHEN ELEMENT IS IN VIEWPORT
$(function inviewport(){
$('animation_container').isInViewport(function init() {
if (status === 'entered') {
alert('Entered');
}
})(function (global, factory) {
typeof exports === 'object' && typeof module !== 'undefined' ? factory(require('jquery')) :
typeof define === 'function' && define.amd ? define(['jquery'], factory) :
(factory(global.jQuery));
}(this, (function ($) { 'use strict';
$ // expose isInViewport as a custom pseudo-selector= $ && $.hasOwnProperty('default') ? $['default'] : $;
// DETECT ELEMENT WHEN IT IS IN VIEWPORT
/**
* @author Mudit Ameta
*/
// expose isInViewport as a custom pseudo-selector
$.extend($.expr.pseudos || $.expr[':'], {
// if $.expr.createPseudo is available, use it
'in-viewport': $.expr.createPseudo
? $.expr.createPseudo(function (argsString) { return function (currElement) { return isInViewport(currElement, getSelectorArgs(argsString)); }; })
: function (currObj, index, meta) { return isInViewport(currObj, getSelectorArgs(meta[3])); }
});
// expose isInViewport as a function too
// this lets folks pass around actual objects as options (like custom viewport)
// and doesn't tie 'em down to strings. It also prevents isInViewport from
// having to look up and wrap the dom element corresponding to the viewport selector
$.fn.isInViewport = function(options) {
return this.filter(function (i, el) { return isInViewport(el, options); })
};
$.fn.run = run;
// lets you chain any arbitrary function or an array of functions and returns a jquery object
function run(args) {
var this$1 = this;
if (arguments.length === 1 && typeof args === 'function') {
args = [args];
}
if (!(args instanceof Array)) {
throw new SyntaxError('isInViewport: Argument(s) passed to .do/.run should be a function or an array of functions')
}
args.forEach(function (arg) {
if (typeof arg !== 'function') {
console.warn('isInViewport: Argument(s) passed to .do/.run should be a function or an array of functions');
console.warn('isInViewport: Ignoring non-function values in array and moving on');
} else {
[].slice.call(this$1).forEach(function (t) { return arg.call($(t)); });
}
});
return this
}
// gets the width of the scrollbar
function getScrollbarWidth(viewport) {
// append a div that has 100% width to get true width of viewport
var el = $('<div></div>').css({
width: '100%'
});
viewport.append(el);
// subtract true width from the viewport width which is inclusive
// of scrollbar by default
var scrollBarWidth = viewport.width() - el.width();
// remove our element from DOM
el.remove();
return scrollBarWidth
}
// Returns true if DOM element `element` is in viewport
function isInViewport(element, options) {
var ref = element.getBoundingClientRect();
var top = ref.top;
var bottom = ref.bottom;
var left = ref.left;
var right = ref.right;
var settings = $.extend({
tolerance: 0,
viewport: window
}, options);
var isVisibleFlag = false;
var $viewport = settings.viewport.jquery ? settings.viewport : $(settings.viewport);
if (!$viewport.length) {
console.warn('isInViewport: The viewport selector you have provided matches no element on page.');
console.warn('isInViewport: Defaulting to viewport as window');
$viewport = $(window);
}
var $viewportHeight = $viewport.height();
var $viewportWidth = $viewport.width();
var typeofViewport = $viewport[0].toString();
// if the viewport is other than window recalculate the top,
// bottom,left and right wrt the new viewport
// the [object DOMWindow] check is for window object type in PhantomJS
if ($viewport[0] !== window && typeofViewport !== '[object Window]' && typeofViewport !== '[object DOMWindow]') {
// use getBoundingClientRect() instead of $.Offset()
// since the original top/bottom positions are calculated relative to browser viewport and not document
var viewportRect = $viewport[0].getBoundingClientRect();
// recalculate these relative to viewport
top = top - viewportRect.top;
bottom = bottom - viewportRect.top;
left = left - viewportRect.left;
right = right - viewportRect.left;
// get the scrollbar width from cache or calculate it
isInViewport.scrollBarWidth = isInViewport.scrollBarWidth || getScrollbarWidth($viewport);
// remove the width of the scrollbar from the viewport width
$viewportWidth -= isInViewport.scrollBarWidth;
}
// handle falsy, non-number and non-integer tolerance value
// same as checking using isNaN and then setting to 0
// bitwise operators deserve some love too you know
settings.tolerance = ~~Math.round(parseFloat(settings.tolerance));
if (settings.tolerance < 0) {
settings.tolerance = $viewportHeight + settings.tolerance; // viewport height - tol
}
// the element is NOT in viewport iff it is completely out of
// viewport laterally or if it is completely out of the tolerance
// region. Therefore, if it is partially in view then it is considered
// to be in the viewport and hence true is returned. Because we have adjusted
// the left/right positions relative to the viewport, we should check the
// element's right against the viewport's 0 (left side), and the element's
// left against the viewport's width to see if it is outside of the viewport.
if (right <= 0 || left >= $viewportWidth) {
return isVisibleFlag
}
// if the element is bound to some tolerance
isVisibleFlag = settings.tolerance ? top <= settings.tolerance && bottom >= settings.tolerance : bottom > 0 && top <= $viewportHeight;
return isVisibleFlag
}
// get the selector args from the args string proved by Sizzle
function getSelectorArgs(argsString) {
if (argsString) {
var args = argsString.split(',');
// when user only gives viewport and no tolerance
if (args.length === 1 && isNaN(args[0])) {
args[1] = args[0];
args[0] = void 0;
}
return {
tolerance: args[0] ? args[0].trim() : void 0,
viewport: args[1] ? $(args[1].trim()) : void 0
}
}
return {}
}
})));
//# sourceMappingURL=isInViewport.js.map
});
Sadly :
- it work only one time. If you keep scrolling and come back it wont trigger the function again.
- it start at the top of the element.
- due to the final use i'll do with the animation, i'll have to ad an "if" to make it work only on small screens
If someone know how to improve it ?
I haven't managed to stop the autoplay to have the animation paused on the first key or the poster onload.
