如何使用jQuery在发票中使用总计数折扣值和总GST值以及总计数行使用

问题描述

我正在尝试使用jQuery在发票中使用总计数“ DCS折扣”值和总“ gst”值以及总计数“行”。

示例

我在jQuery代码中尝试过此方法，但是它不起作用

$('tbody').delegate('.quantity,.price,.gst,.dsc','keyup',function() {
  var tr = $(this).parent().parent();
  var quantity = tr.find('.quantity').val();
  var price = tr.find('.price').val();
  var gst = tr.find('.gst').val();
  var dcs = tr.find('.dcs').val();
  var totalprice = quantity * price;
  var totaldiscount = (totalprice * dcs) / 100;
  var totalvatable = totalprice - totaldiscount;
  var totalvat = (totalvatable * gst) / 100;
  var totalamount = totalvatable + totalvat;


  tr.find('.totalamount').val(totalamount);
  total();
});

function total() {
  var total = 0;
  $('.totalamount').each(function(i,e) {
    var totalamount = $(this).val() - 0;
    total += totalamount;
  });
  $('.total').val(total + ".00");
} 

我的观点

<table>
  <tbody>
    <tr>
      <td> <input style="text-align:center;" type="text" class="text-danger  input-lg form-control quantity" name="qty[]" id="validationServer01" placeholder="QTY" value="" required pattern="[1-2-3-4-3-5-6-7-8-9-10-12]+" numbers="onlynumbers" autocomplete="off"></td>
      <td> <input style="text-align:center;" type="text" class="text-danger  input-lg form-control gst " name="gst_amount[]" id="validationServer01" placeholder="GST" value="" required pattern="[1-2-3-4-3-5-6-7-8-9-10-12]+" numbers="onlynumbers" autocomplete="off"></td>
      <td> <input style="text-align:center;" type="text" class="text-danger  input-lg form-control dcs " name="dcs_amount[]" id="validationServer01" placeholder="DCS" value="" required pattern="[1-2-3-4-3-5-6-7-8-9-10-12]+" numbers="onlynumbers" autocomplete="off"></td>
      <td> <input style="text-align:center;" type="number" class="text-danger  input-lg form-control price" name="purchase_rate[]" id="validationServer01" placeholder="RATE" value="" required pattern="" numbers="" autocomplete="off"></td>
      <td> <input style="text-align:center;" type="text" class="text-danger  input-lg form-control totalamount" name="" id="validationServer01" placeholder="AMOUNT" value="" required pattern="[1-2-3-4-3-5-6-7-8-9-10-12]+" numbers="onlynumbers" disabled></td>
    </tr>
  </tbody>
</table>

解决方法

嗨，我认为这可能会解决您的问题，将其放在您的控制器中，然后在刀片服务器模板中调用它

$total_amount = YOURMODEL::all()->sum('THECOLUMN');
or
$total_amount= YOURMODEL::all()->pluck('THECOLUMN')->sum();

让我知道是否仍然存在问题
