这样的字符串如何转换成一个数组？

Question

 var arrData='["2015-06-02 13:23:30","2015-06-02 13:22:30","2015-06-03 13:23:30","2015-06-04 13:23:30","2015-06-05 13:23:30",]';

我想最终的效果是这个新数组A[0]的值为2015-06-02 13:23:30

Answer 1

 var arrData='["2015-06-02 13:23:30","2015-06-02 13:22:30","2015-06-03 13:23:30","2015-06-04 13:23:30","2015-06-05 13:23:30",]'
 var arr = eval('('+arrData+')');
 for(var i=0;i<arr.length;i++){
   alert(arr[i]);
 }
