javascript - 具有多个值的数组的 JavaScript 输出显示单词“对象，对象”

Question

var dynastyReign = [ 
{"San Dynasty": "MXLI"},
{"Viloria Dynasty": "MCCCIIII"},
{"Tan Dynasty": "MCCCXCVIII"},  
{"Bon Dynasty": "MCDXLV"},   
{"Maiko Dynasty": "MDCLXIV"}, 
{"Paul Dynasty": "MCMXLIX"},
{"Andre Dynasty": "MMMXICX"}
];

document.write(dynastyReign.toString());

我尝试使用 toString 输出这个数组，每个数组都有两个值，但输出只给了我[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object].

如何停止显示对象词，如果可能的话，我还希望只显示罗马数字部分，删除“王朝”。

尝试这个：

var dynastyReign = [ 
  {"San Dynasty": "MXLI"},
  {"Viloria Dynasty": "MCCCIIII"},
  {"Tan Dynasty": "MCCCXCVIII"},  
  {"Bon Dynasty": "MCDXLV"},   
  {"Maiko Dynasty": "MDCLXIV"}, 
  {"Paul Dynasty": "MCMXLIX"},
  {"Andre Dynasty": "MMMXICX"}
];

var text = dynastyReign.map(d => Object.values(d)[0])
document.write(text);
