目前我有这个,但它一直返回“swapBKgnd is no defined”:
var interval = self.setInterval("swapBKgnd()", 9000);
function swapBKgnd() {
(direction === 'next') ? ++current : --current;
if (current === 0) {
current = imgsLenth;
direction = 'next';
} else if (current - 1 === imgsLenth) {
current = 1;
loc = 0;
}
transition(sliderUL, loc, direction);
};
谢谢。
