Answer 1

这不是对坏 object 序列化的认可

如果您绝对必须使用这种格式的数据，您可以将单引号替换为双引号，以使其符合 JSON：

 const data = [ { "Name": "Martine of Martine's Table", "City": "Amsterdam", "Cuisine_Style": "['French', 'Dutch', 'European']", "Ranking": 1, "Rating": 5, "Number of Reviews": 136 }, { "Name": "De Silveren Spiegel", "City": "Amsterdam", "Cuisine_Style": "['Dutch', 'European', 'Vegetarian Friendly', 'Gluten Free Options']", "Ranking": 2, "Rating": 4.5, "Number of Reviews": 812 } ]; for (const item of data) item['Cuisine_Style'] = JSON.parse(item['Cuisine_Style'].replace(/'/g, '"')); console.log(data);

Answer 2

尝试这个。

 var arr_data = [{ "Name": "Martine of Martine's Table", "City": "Amsterdam", "Cuisine_Style": "['French', 'Dutch', 'European']", "Ranking": 1, "Rating": 5, "Number of Reviews": 136 }, { "Name": "De Silveren Spiegel", "City": "Amsterdam", "Cuisine_Style": "['Dutch', 'European', 'Vegetarian Friendly', 'Gluten Free Options']", "Ranking": 2, "Rating": 4.5, "Number of Reviews": 812 } ]; var y = JSON.stringify(arr_data); var x = y.toString(); console.log(x);
