我正在使用這個(gè)jquery 中繼器。我對(duì)表單的每次加法使用自定義計(jì)算，例如將一個(gè)輸入與另一個(gè)輸入相乘，然后得出乘法結(jié)果的總和。問(wèn)題是，當(dāng)我們單擊刪除時(shí)，它只是隱藏該行，但不刪除該項(xiàng)目的值，當(dāng)我們刪除另一個(gè)項(xiàng)目時(shí)，它將刪除隱藏的第一個(gè)項(xiàng)目，并且我的計(jì)算得到更新。我檢查刪除項(xiàng)目時(shí)的類(lèi)數(shù)，第一次刪除時(shí)它不會(huì)減少，第二次刪除時(shí)它總是減少，如何完全刪除該行及其值？var _CalTotal = function () {console.log($(".billitem_quantity").length );//Calculate total of quantityvar total_quantity = 0;$(".billitem_quantity").each(function(){    total_quantity += parseFloat($(this).val()); });$('#itemquantity_total').val(total_quantity.toFixed(2));**//Calculate total of amount**var total_amount = 0;$(".billitem_total").each(function(){    total_amount += parseFloat($(this).val());});$('#bill_total').val(total_amount.toFixed(2));console.log('test');}下面是隱藏的代碼，hide: function(deleteElement) {      Swal.fire({    title: "Are you sure to cancel this order?",    text: "You will not able to revert this",    icon: "question",    showCancelButton: true,    confirmButtonText: "Yes, delete it!",    cancelButtonText: "No, revert it!",    reverseButtons: true,    }).then(function(result) {    if (result.value) {        $(this).slideUp(deleteElement);                 //I guess something is missing here to delete that item with first delete fire.              _CalTotal();  //Here i am calling calltotal function.    } else if (result.dismiss === "cancel") {    }});                                                  },
