如何使用 javascript 将以下格式更改为 json 格式

Question

我想转换这种数据格式：

"color;blue:36 ,red:27"

以下JSON格式：

{
  "Record": [
    {
      "type": "color",
      "data": "blue",
      "total": "36"
    },
    {
      "type": "color",
      "data": "red",
      "total": "27"
    }
  ]
}

Answer 1

这个提议首先用分号分割字符串以获得type和数据，用' ,'分隔。然后用冒号分割 data 和 total.

var data = 'color;blue:36 ,red:27',
    parts = data.split(';'),
    object = {
        Record: parts[1].split(' ,').map(function (a) {
            var p = a.split(':');
            return { type: parts[0], data: p[0], total: p[1] };
        })
    };

console.log(object);

.as-console-wrapper { max-height: 100% !important; top: 0; }

Answer 2

很难理解给定输入的确切问题，但这应该足够了：

    var input = "color;blue:36 ,red:27";

    // Reassignment is bad, but will shorten the example
    input = input.split(";");

    var attributeName = input[0];

    // No length validations, also bad
    var attributes = input[1].split(",");

    var results = {"Record": attributes.map(function(a) {
        a = a.split(":");
        return {"type":attributeName,
            "data":a[0].trim(),
            "total": a[1].trim()}
    })};

    console.log(results)

Answer 3

这是我的做法

var dataFormat = "color;blue:36 ,red:27"
var splitFormat = dataFormat.split(";");
var type = splitFormat[0];
var colors = splitFormat[1].split(",");
var results = [];
_.each(colors, function(color) {
console.log(color)  
  var obj = {
    "type": type,
    "data": color.split(":")[0],
    "total":color.split(":")[1]
  }
  results.push(obj);
});
var final = {
  "Result": results
};
$("#result").html(JSON.stringify(final));
