JavaScript数据转换问题

Question

如何用JavaScript把 var string = "112312312312100,112312312312103,112312312312105-111,112312312312106,112312312312102";
转换成类似 [{"earMark":"112312312312100"},{"earMark":"112312312312103"},{"earMark":"112312312312105-111"},{"earMark":"112312312312106"},{"earMark":"112312312312102"}]
