        $("#tgl").val("");
        $("#idpembelian").val("");
        $("#idbarangpembelian").val("");
        $("#namabarangpembelian").val("");
        $("#kemasan").val("");
        $("#jumlah").val("");
        $("#harga").val("");
        $("#isi").val("");
        $("#total").val("");
        $("#pembelian").load("proses.php", "op=pembelian");
    }
});

Answer 1

错字：

"&isi=" + isi = "

=应为+

harga + "&isi=" + isi + "&total=" + total,
