Stagger js svg animation
Question
I'm using vivus.js to animate an svg which is repeated multple times (as part of a php loop).
i'm looking for a way to stagger the animation, so that svg id 'hexx--0' animates first and then when complete, svg id 'hexx--1' animates and so on. The ID number is being incremented in the php loop.
I've attempted to literally chain these in a function that fires when the first animation finishes, like so:
new Vivus('hexx--0', {
type: 'oneByOne',
duration: 100
}, function() {
new Vivus('hexx--1', {
type: 'oneByOne',
duration: 100,
});
});
which works, but a) means the svg is visible before the animation fires and b) is messy and unmaintainable across a loop which could have an arbitrary amount of svgs.
Is it possible to increment the IDs in JavaScript, and generate the new Vivus in a loop? Below is a fiddle which replicates the issue, note that the html is being generated via a php loop in the real case.
//all animating at same time new Vivus('hexx--0', { type: 'oneByOne', duration: 100, }); new Vivus('hexx--1', { type: 'oneByOne', duration: 100, }); //attempt at staggering new Vivus('hexx--2', { type: 'oneByOne', duration: 100 }, function() { new Vivus('hexx--3', { type: 'oneByOne', duration: 100, }); });
svg { stroke: #000000; }

I eventually figured this out, having secured a tumbleweed badge for my troubles.
Step 1: in JavaScript, increment the ids with a for loop:
//increment the ids
var i;
for (i = 0; i < 7; i++) {
new Vivus('hexx--' + i, {
type: 'scenario-sync'
});
}
I changed the type to 'scenario-sync' which means you can set the duration and delay using html data attributes.
Step 2: in PHP I added the data attributes to the path like so:
path data-delay="<?php echo $delay ?>" data-duration="<?php echo $duration ?>"
and incremented the values in a php loop accordingly.
