vue中使用FileSaver.js，怎么导出多条数据的vcf文件

var file = new File([
                      "BEGIN:VCARD"+"\n"  +
                      "VERSION:3.0"+"\n" +
                      "N:"  + "张三"+"\n" + 
                      "FN:" + "张三"+"\n" + 
                      "TEL;TYPE=CELL:" + "13838380438"+"\n"+
                      "END:VCARD"
                     ], {type: "text/plain;charset=utf-8"});
                    
                    FileSaver.saveAs(file, "hello.vcf");

那循环 一下 导出
