这是促销页面: http: //www.apple.com/itunes/50-billion-app-countdown/
它链接了一个js: http: //www.apple.com.cn/v/itunes/50-billion-app-countdown/a/scripts/counter.js
AC.onDOMReady(function() {
var e = "j", t = new Counter({
container: AC.Element.selectAll(".counter")[0],
dataURL: "/itunes/store/counters/il6ark7ec." + e + "s",
staticImagePath: "http://images.apple.com/itunes/shared/counter/images/counter_noscript.png",
targetCount: 50000000000,
stopAtTargetCount: true
});
});
所以拼接字符串
var e="j"
"/itunes/store/counters/il6ark7ec." + e + "s"
至
http://www.apple.com.cn/itunes/store/counters/il6ark7ec.js
有用吗?还是只是为了好玩..?
