Why the progeny selector doesn't work?

for (var i = 0; I < 2; iPP) {

$("-sharpactivity_time"+i+" a").removeClass("buy_button");

} 

<input type="hidden" name="activity_time" id="activity_time0" value="2018/4/25 16:13:59" />
<a href="-sharp" class="buy_button"></a>

< / div > 

<input type="hidden" name="activity_time" id="activity_time1" value="2018/4/25 16:13:59" />
<a href="-sharp" class="buy_button"></a>

< / div >
