将序列号从字符串或txt文件复制到列表框

# 从字符串复制序列号到列表框

serial_numbers = serial_numbers_str.split(", ")
for sn in serial_numbers:

# 从txt文件复制序列号到列表框

// 从字符串复制序列号到列表框
var serialNumbersStr = "SN1, SN2, SN3";
var serialNumbers = serialNumbersStr.split(", ");
serialNumbers.forEach(function(sn) {
    listbox.addItem(sn);
});

// 从txt文件复制序列号到列表框
fetch("serial_numbers.txt")
    .then(response => response.text())
    .then(serialNumbersStr => {
        var serialNumbers = serialNumbersStr.split("\n");
