創建基於另一個JSON作為鍵和值的JSON嗎？

Question

我有json之類的

SampJson= [
    {
        data: "50",
        cIndex: "column0",rowno:"1"
    },
    {
        data: "5",
        cIndex: "column1",rowno:"1"
    },
    {
        data: "80",
        cIndex: "column0",rowno:"2"
    },
    {
        data: "65",
        cIndex: "column1",rowno:"2"
    }

]。

我需要創建一個JSON

[
    {
        rowno:1,
        column0:50,
        column1:5
    },
    {
        rowno:2,
        column0:80,
        column1:65
    }
];

提前致謝...

您應該這樣做：

 sampJson = [ { data: "50", cIndex: "column0", rowno: "1" }, { data: "5", cIndex: "column1", rowno: "1" }, { data: "80", cIndex: "column0", rowno: "2" }, { data: "65", cIndex: "column1", rowno: "2" } ]; var results = []; sampJson.forEach(function(el) { if (results[+el.rowno - 1] == null) { results[+el.rowno - 1] = new Object(); } results[+el.rowno - 1].rowno = +el.rowno; results[+el.rowno - 1][el.cIndex] = +el.data; }); console.log(results);
