JavaScript将数组转换成CSV格式

JavaScript中数组对象的valueOf方法可以将数组的值输出为逗号分割的字符串，下面的代码演示了如何将数组抓换成逗号和竖线分割的字符串

var fruits = ['apple', 'peaches', 'oranges', 'mangoes'];
// http://www.75271.com  
var str = fruits.valueOf();
  
//输出结果: apple,peaches,oranges,mangoes

如果希望使用竖线|分割

var fruits = ['apple', 'peaches', 'oranges', 'mangoes'];
// http://www.75271.com
var str = fruits.join("|");
  
//print str: apple|peaches|oranges|mangoes

完整演示代码如下
