我有一个包含 3 个选择选项值的表格；airdate_year、airdate_month 和 airdate_day。还有一个名为 episode_airdate[] 的隐藏字段来存储所有 3。这里的问题是表 tr 是使用 javascript 克隆的，因此这些值没有正确发送到 episode-airdate，有什么想法吗？
这是我用来组合 3 个选择值以生成隐藏字段值的脚本。
<script>
function datepopulate(){
var day = document.getElementById('airdate_day').value;
var month = document.getElementById('airdate_month').value;
var year = document.getElementById('airdate_year').value;
var completedate = day+'-'+month+'-'+year;
document.getElementById('episode_airdate[]').value = completedate;
alert(document.getElementById('episode_airdate[]').value);
return true;
}
</script>
