JS实现图片延时启动与定时闪动效果

var inter={};
var i=0;
$(document).ready(function(){
$("a").each(function(index,item){
$(this).bind().click(function(){
i=index;
if(inter!=null || inter.length>0){
window.clearInterval(inter);
}

window.setTimeout(function(){
inter=window.setInterval(function(){ $("img").eq(i).show().fadeOut(100).fadeIn(100);},500);
window.setTimeout(function(){
window.clearInterval(inter);
},5000);
},5000);

});

});
window.setTimeout(function(){
inter=window.setInterval(function(){ $("img").eq(i).show().fadeOut(100).fadeIn(100);},500);
window.setTimeout(function(){
window.clearInterval(inter);
},5000);
},5000);
});
