>我需要从数组对象中获取一个唯一值。例如，我有以下数据，

   var empDetails =[
{"name":"dinesh","age":"24","companyName":"ABC","designation":"developer"},
{"name":"dinesh","age":"24","companyName":"ABC","designation":"developer"},{"name":"dinesh","age":"24","companyName":"ABC","designation":"TestEngr"},
{"name":"Ramesh","age":"24","companyName":"ABC","designation":"developer"}];

从这个对象中，我想获得唯一的数组详细信息。输出应如下所示：

uniqueDet = [
{"name":"dinesh","age":"24","companyName":"ABC","designation":"developer"},
 {"name":"dinesh","age":"24","companyName":"ABC","designation":"TestEngr"},
    {"name":"Ramesh","age":"24","companyName":"ABC","designation":"developer"}]

根据公司名称和名称，我想获得独特的详细信息。你能给我解决这个问题的解决方案吗？提前谢谢。

var uniqueDet = empDetails.filter(function(x, i) {
    return empDetails.map(function(e) { 
        return JSON.stringify(e)
     }).indexOf(JSON.stringify(x)) == i;
});
