以下就是小米搶購時的JS代碼，分析一下就可以用它實現一個紅米搶購軟件，大家根據這個代碼實現自己想要的功能吧！

復制代碼 代碼如下:

hdcontrol({"stime":1381645438,"status":{"allow":false,"miphone":{"hdstart":false,"hdstop":false,"hdurl":"","duration":null},"mibox":{"hdstart":false,"hdstop":false,"hdurl":"","duration":null}}})

復制代碼 代碼如下:

function forNum(a){
return 10>a?"0"+a:a
}
function countdown(a,b){
varc=newDate(b).getTime()/1e3,
d=c-a,
e=parseInt(d%60),
f=parseInt(d/60%60),g=parseInt(d/3600%24),
h=parseInt(d/3600/24),
i=[e.toString(),
f.toString(),
g.toString()];

return0>=d?["00小時00分00秒",!0]:h>0?(window._timestr=h+"天"+forNum(i[2])+"時"+forNum(i[1])+"分"+forNum(i[0])+"秒",[h+"<span>天</span>"+forNum(i[2])+"<span>時</span>"+forNum(i[1])+"<span>分</span>"+forNum(i[0])+"<span>秒</span>",!1]):(window._timestr=forNum(i[2])+"時"+forNum(i[1])+"分"+forNum(i[0])+"秒",[forNum(i[2])+"<span>時</span>"+forNum(i[1])+"<span>分</span>"+forNum(i[0])+"<span>秒</span>",!1])}
functionWebEventTrigger(a,b){
try{
if(WE&&WE.trigger)
return"string"!=typeofb&&(b=JSON.stringify(b)),WE.trigger(a,b)
}catch(c){}
return!1
}
functionisApp(){
try{
if(WE)return!0
}catch(a){}
return!1
}
