如何在jquery中将逗号分隔的字符串转换为数字（整数）数组

Question

我需要将具有多个数字的字符串转换为jQuery中的数组。我的字符串如下：

var strVal = "901,235,342,421,345,745,544,324,445,123,232,986,345,678";

Answer 1

您可以将String.split与','一起使用，然后将Array#map与Number转化后的值

一起使用

＆＃13;

var strVal = "901,235,342,421,345,745,544,324,445,123,232,986,345,678",
    numbers = strVal.split(',').map(Number);

console.log(numbers);

＆＃13;

.as-console-wrapper { max-height: 100% !important; top: 0; }

＆＃13;

＆＃13;
