把一个数组遍历倒序放到另一个数组中，数组取值是c：out value

 1 var year = "<c:out value="${year}" />";
 2
 3 var years = [];
 4
 5             var yearDataArray = [];
 6 //遍历year，放进yearDataArray中
 7             $("#year option[value!=‘‘]").each(function(){
 8                 yearDataArray.push($(this).text());
 9             });
10 //yearDataArray排序
11             yearDataArray = yearDataArray.sort(function(a,b){
12                 return a-b;
13                 })
14 //对yearDataArray 的每一个值加上后缀,放进years中
15              $.each(yearDataArray, function(i, d){
16                 years.push(yearDataArray[i]+"-01-01");
17             });
