在过去的几天时间里面，我主要集中精力实现Contest 的的Rank以及Status功能
Rank实现代码####
###前端
<br>
<table class="table table-bordered table-hover text-center" id = "rank_table">
<thead>
</thead>
<tbody>
</tbody>
</table>
<script type="text/javascript">
function str_pad_left(string,pad,length) {
return (new Array(length+1).join(pad)+string).slice(-length);
}
function secondsToTime(secs)
{
var hours = Math.floor(secs / (60 * 60));
var divisor_for_minutes = secs % (60 * 60);
var minutes = Math.floor(divisor_for_minutes / 60);
var divisor_for_seconds = divisor_for_minutes % 60;
var seconds = Math.ceil(divisor_for_seconds);
return hours + ":" + str_pad_left(minutes,'0',2)+':'+str_pad_left(seconds,'0',2);;
}
function refreshRankList(){
$.ajax({
type: "post",
url: "/contest/" + {{ contest.id }} + "/rank/",
dataType: "json",
success: function(data){
$("#rank_table tr").remove();
thHTML = "<tr><th class=\"text-center\">Rank</th><th class=\"text-center\">ID</th><th class=\"text-center\">Solve</th><th class=\"text-center\">Penalty</th>"
$.each(data.statsinfo, function(i, item){
thHTML += "<th class=\"text-center\">" + item.probid + "</th>";
});
thHTML += "</tr>";
$("#rank_table thead").append(thHTML);
rank_num = 0;
var last_solved = -1;
var last_penalty = -1;
var rank_list=[];
$.each(data, function(i, item) {
if (item != data.statsinfo) {
rank_list.push(item);
}
});
rank_list.sort(function(a,b){return a.solved==b.solved?a.penalty-b.penalty:b.solved-a.solved;});
$.each(rank_list, function(i, item) {
if (item != data.statsinfo) {
if(item.solved!=last_solved || item.penalty!=last_penalty)
rank_num += 1;
last_solved=item.solved;
last_penalty=item.penalty;
trHTML = "<tr><td style=\"align:center;\">" + rank_num +
"</td><td class=\"text-center\">" + item.name +
"</td><td>" + item.solved +

$.each(item.probs, function(i, pitem){

} else {

}
}
});
trHTML += "</tr>"
$("#rank_table tbody").append(trHTML);
}
});
thHTML = "<tr><td></td><td></td><td></td><td></td>";
$.each(data.statsinfo, function(i, item){
thHTML += "<td style=\"background-color: #D0D0D0;\">" + item.acNum + "/" + item.tryNum + "</td>";
});
thHTML += "<tr>"
$("#rank_table tbody").append(thHTML);
}
});
}
$(document).ready(function () {
refreshRankList();
//setInterval(function(){refreshRankList();},10000);
})
</script>

Status实现代码####
###前端
