我有 Basic Idea使用此UI Dynamic form on Laravel在我的表单上实现，因此我想让Kode在Text Kode上有效（onChanged）在每个Text Input上输入名称Product＆HNA。
我想用javascript实现，但我不知道。因为输入数字3之后的字段是用javascript创建的。
这是我的HTML和javascript：
var pitem = 2;
function add_baris()
{
if(pitem<=10)
{
//Tambah inner baris html
$("#tambahan").append('<tr><td>'+pitem+'.</td><td><input type="text" class="form-control input-sm" name="kode[]"></td><td><input type="text" class="form-control input-sm" name="material[]" readonly></td><td><input type="text" class="form-control input-sm" name="hna[]"></td><td><input type="text" class="form-control input-sm" name="qty[]"></td><td><input type="text" class="form-control input-sm" name="value[]"></td><td><input type="text" class="form-control input-sm" name="persen[]"></td><td><input type="text" class="form-control input-sm" name="biaya[]"></td><td><button class="btn btn-sm btn-danger" title="Hapus"><span class="fa fa-trash"></span></button></td></tr>');
//Tambah baris
pitem++;
//Hapus baris
$("#tambahan").find("button").on('click',function(){
$(this).parent().parent().remove();
if(pitem!=2){
document.getElementById('jitem').value=pitem-1;
pitem=pitem-1;
}
});
}
else{
alert('Produk tidak boleh lebih dari 10 item');
}
