问题描述
我的问题是计算工作正常,但是当删除该行时,计算不会根据创建新行并执行计算后的值进行更新。请帮助我纠正此问题。 / p>
My problem is the calculations are working fine but when the row is removed the calculations are not updating according to that after creating a new row and after performing calculation only the values are updating..please help me to rectify this problem.
$(document).on('change', 'tr td:nth-child(6), tr td:nth-child(5), tr td:nth-child(4)', .
'remove3'
function() {
var total = 0;
var sqty = 0;
var tr = $(this).parent();
var qty = tr.find('td:nth-child(4)').find('input').val();
var rate = tr.find('td:nth-child(5)').find('input').val();
var amount = qty * rate;
tr.find('td:nth-child(6)').find('input').val(amount);
var tbody = tr.parent();
$(tbody).find('tr').each(function() {
total += Number($(this).find('td:nth-child(6)').find('input').val());
sqty += Number($(this).find('td:nth-child(4)').find('input').val());
});
$('#TieTotal').val(total);
$('#SQty').val(sqty);
$('#Grandtot').val(total);
})
自动创建下一行的脚本:
Script to create a next row automatically:
$('.tb3').on('keydown', 'input', function(e) {
var keyCode = e.keyCode;
if (keyCode !== 9) return;
var $this = $(this),
$lastTr = $('tr:last', $('.tb3')),
$lastTd = $('td:last', $lastTr);
if (($(e.target).closest('td')).is($lastTd)) {
var cloned = $lastTr.clone();
cloned.find('input').val('');
$lastTr.after(cloned);
}
});
删除行的脚本:
$(document).on('click', '.remove3', function() {
var trIndex = $(this).closest("tr").index();
if (trIndex > 0) {
$(this).closest("tr").remove();
} else {
alert("Sorry!! Can't remove first row!");
}
});
推荐答案
$(document).on('change', 'tr td:nth-child(6), tr td:nth-child(5), tr td:nth-child(4)', .
'remove3'
function() {
var total = 0;
var sqty = 0;
var tr = $(this).parent();
var qty = tr.find('td:nth-child(4)').find('input').val();
var rate = tr.find('td:nth-child(5)').find('input').val();
var amount = qty * rate;
tr.find('td:nth-child(6)').find('input').val(amount);
var tbody = tr.parent();
$(tbody).find('tr').each(function() {
total += Number($(this).find('td:nth-child(6)').find('input').val());
sqty += Number($(this).find('td:nth-child(4)').find('input').val());
});
$('#TieTotal').val(total);
$('#SQty').val(sqty);
$('#Grandtot').val(total);
})

$('.tb3').on('keydown', 'input', function(e) {
var keyCode = e.keyCode;

if (($(e.target).closest('td')).is($lastTd)) {
var cloned = $lastTr.clone();
cloned.find('input').val('');
$lastTr.after(cloned);
}
});
Script to delete row:
$(document).on('click', '.remove3', function() {
var trIndex = $(this).closest("tr").index();
if (trIndex > 0) {
$(this).closest("tr").remove();
$('.Qty').trigger('change');
} else {
alert("Sorry!! Can't remove first row!");
}
});
