javascript数组到多维数组

Question

我有一个跟在这个线程后面的问题。它是跟随这个答案。

Google Apps Script Spreadsheets - Write Array to cells

我如何得到

var employees=["Adam","Barb","Chris"]; 

到这个样子？

var employees=[["Adam"],["Barb"],["Chris"]]; 

Answer 1

你可以使用map()：

var employees=["Adam","Barb","Chris"]; 

var newEmployees = employees.map(function(item){ return [ item ]; }); 

Answer 2

var employees = ["Adam", "Barb", "Chris"]; 

for (var i = employees.length; i--;) { 
    employees[i] = [employees[i]]; 
}
