使用arraw函数的Matt Zeunert版本(ES6)

const nums = a.split(',').map(x => parseInt(x, 10));

你可以在一行中将字符串数组转换为数字数组:

const arrayOfNumbers = arrayOfStrings.map(e => +e);

一个更简短的解决方案:映射并传递参数给Number:

Var a = "1,2,3,4"; Var b = a.s split('，'); console.log (b); var c = b.map(Number); console.log (c);

这很简单。如:

["1", "2", "3", "4"].map(i=>Number(i))

您可以运行演示。 让结果=(“1”、“2”、“3”、“4”). map (i = > (i)); console.log(结果);

let ar = [ '682',    '874',    '906',    '11168',  '73714',
  '74377',  '74034',  '138860', '138891', '139161', '139562',
  '139733', '139560', '74049',  '139759', '139934', '140104',
  '141335', '141356', '141334', '141337', '141360', '141358',

  '240770', '678151', '678950', '678985'];
let arry=[]
ar.map(arr=>{
arry.push(parseInt(arr))
});

console.log(arry);

将其映射为整数:

a.split(',').map(function(i){
    return parseInt(i, 10);
})

Map查看每个数组项，将其传递给所提供的函数，并返回一个包含该函数返回值的数组。map在旧的浏览器中是不可用的，但是大多数库，如jQuery或underscore都有一个跨浏览器版本。

或者，如果你喜欢循环:

var res = a.split(",");
for (var i=0; i<res.length; i++)
{
    res[i] = parseInt(res[i], 10);
}
