I have some javascript inside a function that creates and populates an image carousel. It works fine after activating it in a pop up window the first 5 or 6 times, but then it eventually crashes the browser. I think there's some kind of leak, like something inside of it needs to be deleted before it gets created again. I know it's the carousel because if I get rid of that part of the script, it no longer crashes.
Here's the carousel script:
/* carousel */
var carousel,
el,
i,
page,
slides;
carousel = new SwipeView('#wrapper', {
numberOfPages: slides.length,
hastyPageFlip: true
});
// Load initial data
for (i=0; i<3; i++) {
page = i==0 ? slides.length-1 : i-1;
el = document.createElement('span');
el.innerHTML = slides[page];
carousel.masterPages[i].appendChild(el)
}
carousel.onFlip(function () {
var el,
upcoming,
i;
for (i=0; i<3; i++) {
upcoming = carousel.masterPages[i].dataset.upcomingPageIndex;
if (upcoming != carousel.masterPages[i].dataset.pageIndex) {
el = carousel.masterPages[i].querySelector('span');
el.innerHTML = slides[upcoming];
}
}
});
This script runs every time I click a link that launches a floating window.
I found out that I needed to clear my wrapper div. In the beginning of my function call:
document.getElementById('wrapper').innerHTML = "";
Seems to work.
