将对象打印为字符串

Question

我已将 json 响应转换为字符串以附加 pdf。summary_data是我想要转换为字符串并附加到 pdf 中的响应。const summary_data=[{Geo: "US West", MeetingHash: "Hold/Uncategorized", count: 65},    {Geo: "NSU", MeetingHash: "Hold/Uncategorized", count: 9},      {Geo: "US East", MeetingHash: "Hold/Uncategorized", count: 3}];           var str="";     $.each(summary_data, function (key, entry) {              str=str.entry."<br>";            });             console.log(str);<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

Answer 1

您可以使用 JSON 方法 stringify()

       constsummary_data=[

        {

          Geo: "US West",

          MeetingHash: "Hold/Uncategorized",

          count: 65

        },

        {

          Geo: "NSU",

          MeetingHash: "Hold/Uncategorized",

          count: 9

        },

        {

          Geo: "US East",

          MeetingHash: "Hold/Uncategorized",

          count: 3

       }

     ];

     console.log(JSON.stringify(summary_data));

您的 JSON 将被转换为字符串。

Answer 2

您可以使用JSON.stringify

试试这个代码：

const summary_data=[{Geo: "US West", MeetingHash: "Hold/Uncategorized", count: 65},{Geo: "NSU", MeetingHash: "Hold/Uncategorized", count: 9}, {Geo: "US East", MeetingHash: "Hold/Uncategorized", count: 3}];

var str = JSON.stringify(summary_data)

       

console.log(str)

Answer 3

尝试使用JSON.stringify

const summary_data=[{Geo: "US West", MeetingHash: "Hold/Uncategorized", count: 65},

{Geo: "NSU", MeetingHash: "Hold/Uncategorized", count: 9},{Geo: "US East", MeetingHash: "Hold/Uncategorized", count: 3}];

// prints as string

console.log(JSON.stringify(summary_data));

// prints as formatted string

console.log(JSON.stringify(summary_data, null, 4));

// prints as <br> concatenated string

var str = "";

$.each(summary_data, function(key, entry) {

  str += JSON.stringify(entry) + "<br>";

});

console.log(str);
