jq调用数据库,该怎么处理

var zjl = false;
			var num = 0;
			var goon = true;
			$(function() {
				$("#scratchpad").wScratchPad({
					width: 150,
					height: 40,
					color: "#a9a9a7",
					scratchMove: function() {
						num++;
					 if (num == 2) {
					  var a = "一等奖";
					  var b = "二等奖";
					  var c = "三等奖";
					  var e = "幸运奖";
					  var d = "谢谢参与";
					  var aa = 0.000;//一等奖的概奖
					  var bb = 0.001;//二等奖的概率
					  var cc = 0.004;//三等奖的概率
					  var ee = 0.996;//幸运奖的概率
					  var dd = 0.000;//未中奖的概率
					
					  var shows = [a, b, c,d,e];
					  var prob = [aa, bb, cc,dd,ee];
					  var len = 1000;
					  var probLen = [len*aa, len*bb, len*cc, len*dd, len*ee];
					  var ran = Math.random() * len;
					  for(var i = 0; i < probLen.length; i++){
					   var ranStart = 0;
					   for(var j = 0; j < i; j++){
						ranStart += probLen[j];
					   }
					   var ranEnd = ranStart + probLen[i];
					
					   if(ran > ranStart && ran <= ranEnd){
						
								var award = shows[i];
								if(shows[i]!='谢谢参与')
								{
									zjl = true;
								}
								
								document.getElementById('prize').innerHTML = award;
								$("#theAward").html(award);

    $data = '{"aa":1,"bb":2,"cc":3,"dd":4}' // 这里也可以从db获取
?>
