将字符串数组 javascript 转换为整数数组 javascript

Question

我有一个数组，

var array = ["1","2","3","4","5"];

然后我需要转换为

var array = [1,2,3,4,5];

如何转换？

Answer 1

The map() method creates a new array with the results of calling a provided function on every element in this array.

The unary + acts more like parseFloat since it also accepts decimals.

参考this

试试这个片段：

var array = ["1", "2", "3", "4", "5"];
array = array.map(function(item) {
  return +item;
});
console.log(array);

Answer 2

将其映射到 Number 函数：

var array = ["1", "2", "3", "4", "5"];
array = array.map(Number);
array; // [1, 2, 3, 4, 5]
