The plugin works correct only on desktop .. and only unfolds on ios 7.1.2 safari )
Thanx in advance!
That's the logic behind opening:
social_icons.addEventListener('click', socialOpen);
function socialOpen(e){
pluginStatus = 2;
social_icons.removeEventListener("click",socialOpen);
social_icons.addEventListener("click", iconClick, false);
window.addEventListener("click", clickOutEvent, false);
draw_icons();
}
function iconClick(e){
window.open(e.target.link);
}
function clickOutEvent(e){
if (e.target.parentNode.id !== "social-plugin"){
pluginStatus = 1;
window.removeEventListener("click",clickOutEvent)
social_icons.removeEventListener("click", iconClick);
social_icons.addEventListener("click", socialOpen, false);
draw_icons();
}
}
