使用forEach向二维数组添加值

Question

我正在尝试在Google Apps脚本中向2D数组添加值。以下代码运行，但不是数组所需的输出。

function fruitList() {
var fruitArray = [['apple'], ['banana'], ['cherry']];
var newArray = [];
fruitArray.forEach(function(value) {
newArray.push([value, "name"]);
});
}

我的代码产生以下输出：

[ [ [ 'apple' ], 'name' ], [ [ 'banana' ], 'name' ], [ [ 'cherry' ], 'name' ] ]

我想要的输出是：

[ [ 'apple', 'name' ], [ 'banana', 'name' ], [ 'cherry', 'name' ] ]

Answer 1

value是一个数组。不是字符串/基元值。您可以使用析构函数赋值来获得实际值：

fruitArray.forEach(function([/*destructure 1D array*/value]) {
newArray.push([value, "name"]);
});

/*<ignore>*/console.config({maximize:true,timeStamps:false,autoScroll:false});/*</ignore>*/ 
function fruitList() {
var fruitArray = [['apple'], ['banana'], ['cherry']];
var newArray = [];
fruitArray.forEach(function([value]) {
newArray.push([value, "name"]);
});
console.info(newArray)
}
fruitList()

Answer 2

添加一个值：

function fruitList() {
var fruitArray = [['apple'], ['banana'], ['cherry']];
var newArray = [];
fruitArray.forEach(function(value) {
newArray.push([value[0], "name"]);
});
Logger.log(JSON.stringify(newArray))
}
Execution log
3:27:33 PM  Notice  Execution started
3:27:34 PM  Info    [["apple","name"],["banana","name"],["cherry","name"]]
3:27:34 PM  Notice  Execution completed
