javascript - 如何在javascript中动态合并数组？

Question

var series = 
[
    [{
        Name: "A",
        Type: "SC"
    }, {
        Name: "B",
        Type: "SC"
    }, {
        Name: "C",
        Type: "SC"
    }, {
        Name: "D",
        Type: "SC"
    }], 
    {
        ColumnName: "Target",
        Type: "Line"
    },
    {
        ColumnName: "bar",
        Type: "Line"
    }
];

我想按如下方式合并数组

var series = [ { Name: "A", Type: "SC" }, { Name: "B", Type: "SC" }, { Name: "C", Type: "SC" }, { Name: "D", Type: "SC" }, { ColumnName: "Target", Type: "Line" }, { ColumnName: "bar", Type: "Line" } ];

非常感谢任何帮助。

JS 有 Array.flat()可以展平数组的方法:

const series = [[{"Name":"A","Type":"SC"},{"Name":"B","Type":"SC"},{"Name":"C","Type":"SC"},{"Name":"D","Type":"SC"}],{"ColumnName":"Target","Type":"Line"},{"ColumnName":"bar","Type":"Line"}];

const flattened = series.flat();

console.log(flattened);

旧答案:

Spread数组变成Array.concat() :

const series = [[{"Name":"A","Type":"SC"},{"Name":"B","Type":"SC"},{"Name":"C","Type":"SC"},{"Name":"D","Type":"SC"}],{"ColumnName":"Target","Type":"Line"},{"ColumnName":"bar","Type":"Line"}];

const flattened = [].concat(...series);

console.log(flattened);
