jQuery.unique在Microsoft Edge中不起作用

Question

positions_list = [
  "M.pharm", 
  "pharmaceutical sales", 
  "pharmacist", 
  "druggist", 
  "MPharm", 
  "pharmaceutical sales", 
  "pharmacist", 
  "druggist", 
  "MPharm"
];

然后使用jQuery.unique(positions_list);，我在Google Chrome（56.x）中获得此结果：

["M.pharm", "pharmaceutical sales", "pharmacist", "druggist", "MPharm"]

然而，MS Edge的结果是：

["M.pharm", "pharmaceutical sales", "pharmacist", "druggist", "MPharm", "pharmaceutical sales", "pharmacist", "druggist", "MPharm"]

您可以看到MS Edge中的结果与原始列表相同。如何在MS Edge中删除列表？

Answer 1

如jquery.unique（）doc所示（@brian Graham在此答案中引用

描述：将一个DOM元素的数组分为原位，并删除了重复项。请注意，这仅适用于DOM元素的数组，而不适用于字符串或数字。
