[英]JavaScript / Google Script - Transpose “Row” Array into “Column” Array
Good afternoon,下午好,
I am attempting transpose a "row" array (or 1D array) into a "column" array (or array that is one array containing individual arrays within it) to allow me to set values to a single column (downward multiple rows) instead if it being one row across multiple columns我正在尝试将“行”数组(或一维数组)转置为“列”数组(或数组,该数组是一个包含单个 arrays 的数组),以允许我将值设置为单个列(向下多行),而不是如果它是跨多列的一行
I attempted using a push loop and a map function but neither attempt succeeded:我尝试使用推送循环和 map function 但均未成功:
function myFunction2() {
var ss=SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Source1");
var lastColumn = ss.getLastColumn()
var endRange = lastColumn-3
//Retrieve values into array named "items"
var items = ss.getRange(16,4,1,endRange).getValues()
Transpose attempt # 1:转置尝试#1:
var colArray = [];
for (var i=0; i<items.length; i++)
{
colArray.push([items[i]]);
}
}
Output for Attempt # 1: Output 用于尝试#1:
[[[item1, item2, item3, item4, item5]]]
Transpose attempt # 2:转置尝试#2:
var colArray = items.map(function (el){
return [el];
});
Output for attempt # 2: Output 用于尝试#2:
[[[item1, item2, item3, item4, item5]]]
The intended output I would like to have is:我想要的预期 output 是:
[[item1], [item2], [item3], [item4], [item5]]
Would there be a way to achieve the intended output?有没有办法实现预期的 output?
In your script of var items = ss.getRange(16,4,1,endRange).getValues()
, items
is 2 dimensional array like [[value1, value2, value3,,,]]
.在您的var items = ss.getRange(16,4,1,endRange).getValues()
脚本中, items
是二维数组,如[[value1, value2, value3,,,]]
。 So, when your script is modified, it becomes as follows.所以,当你的脚本被修改时,它变成如下。
var colArray = [];
for (var i=0; i<items.length; i++)
{
colArray.push([items[i]]);
}
}
var colArray = [];
for (var i = 0; i < items[0].length; i++) {
colArray.push([items[0][i]]);
}
And,和,
var colArray = items.map(function (el){
return [el];
});
var colArray = items[0].map(function (el){
return [el];
});
Or, when you want to transpose the values including the several rows and columns, you can also use the following script.或者,当您想要转置包括多行和多列的值时,您还可以使用以下脚本。
const colArray = items[0].map((_, i) => items.map(row => row[i]));
