jQuery Sum或Multiply值始终没有事件触发器

标签: javascript jquery sum blur multiplying

大家好我有一个动态表(从ajax请求中添加行),我总是需要求和和乘以值(没有触发事件)。

我已经有了一个使用事件(模糊)的功能,但我不想通过使用模糊触发器来实现它。

有办法吗?

我的代码:

$.fn.sumValues = function() {
  var sum = 0;
  this.each(function() {
    if ($(this).is(':input')) {
      var val = $(this).val();
    } else {
      var val = $(this).text();
    }
    sum += parseFloat(('0' + val).replace(/[^0-9-\.]/g, ''), 10);
  });
  return sum;
};

function totaliza() {
  var total_recep = $('input[name^="costot"]').sumValues();
  $('#total_art').val(total_recep);
}
var counter = 0;
$(document).on('click', '#bt_add', function(e) {
  counter++;
  var tr = '<tr id="art_' + counter + '">';
  tr = tr + '<td><button name="del_art' + counter + '" id="del_art' + counter + '" class="btn btn-default btn-xs del_art" type="button">DEL</button></td>';
  tr = tr + '<td><input name="cbarra' + counter + '" id="cbarra' + counter + '" class="form-control" value="02020202" readonly></td>';
  tr = tr + '<td><input name="art' + counter + '" id="art' + counter + '" class="form-control" value="ARTICULO" readonly></td>';
  tr = tr + '<td><select name="und' + counter + '" id="und' + counter + '" class="form-control list"></select></td>';
  tr = tr + '<td><input name="cal' + counter + '" id="cant' + counter + '" class="form-control numeric cal" value="0"></td>';
  tr = tr + '<td><input name="cal' + counter + '" id="costou' + counter + '" class="form-control numeric cal" value="0"></td>';
  tr = tr + '<td><input name="costot' + counter + '" id="costot' + counter + '" class="form-control cal" readonly value="0"></td>';
  tr = tr + '</tr>';
  $("#inv_recep_det tbody").append(tr);
  $('.form-control').change(function() {
    var number = this.name.replace('cal', '');
    var costot = ($('#cant' + number).val() * $('#costou' + number).val())
    $('input[name^="costot' + number + '"]').val(costot);
    totaliza();
  });
  $('.del_art').click(function() {
    var number = this.name.replace('del_art', '');
    $('#art_' + number).remove();
    totaliza();
  });
});

我认为答案可能更好用,而不是继续发表评论。目前,您使用:

 $(".form-control).change(...)

触发更新。某些浏览器可能会强制您失去对元素的关注以实际触发它。相反,将该行更改为:

$(".form-control").on("input", function(){ ... })
