[英]I need to convert an array of arrays into an arrays of objects
I am trying to convert an array of arrays into an array of objects, I am working with Angular and TypeScript, this is the code:我正在尝试将 arrays 数组转换为对象数组,我正在使用 Angular 和 TypeScript,这是代码:
look(data: [][]){
const found = data.flatMap( element => element ).find(element => element == this.codigo );
console.log(found);
const dataobj = data.map(function(row){
return {
a: row[0],
b: row[1],
c: row[2],
d: row[3],
e: row[4],
f: row[5],
g: row[6],
}
});
console.log(dataobj);
console.log(this.datos);
}
And I am getting this error: src/app/hojaexcel/hojaexcel.component.ts:61:16 - error TS2493: Tuple type '[]' of length '0' has no element at index '0'.我收到此错误:src/app/hojaexcel/hojaexcel.component.ts:61:16 - 错误 TS2493:长度为“0”的元组类型“[]”在索引“0”处没有元素。
61 a: row[0], ~ 61 a: 行 [0], ~
The type []
is a tuple type and not an array type. []
类型是元组类型,而不是数组类型。 You can have [number]
, [number, string]
etc... these are all tuple types.你可以有
[number]
, [number, string]
等等......这些都是元组类型。 []
would be a tuple with no elements. []
将是一个没有元素的元组。 [][]
is a tuple of a tuple with no elements, literally [[]]
. [][]
是没有元素的元组的元组,字面意思是[[]]
。
You need to declare a type for it to be an array of an array.您需要声明一个类型以使其成为数组的数组。 I'm not sure what
data
is supposed to be, but let's assume it is a number:我不确定
data
应该是什么,但我们假设它是一个数字:
look(data: number[][]) {
