js将字符串'ALD001022100494'、'ALD001022100494,ALD001022100494'、'ALD001022100494,ALD001022100494,ALD001022100494'等以','分割成数组

可以使用JavaScript中的split()方法将字符串以逗号为分隔符分割成数组。具体实现方法如下：

var str = 'ALD001022100494,ALD001022100494,ALD001022100494';
var arr = str.split(',');
console.log(arr);

运行结果为：

["ALD001022100494", "ALD001022100494", "ALD001022100494"]
