添加/删除表行时更新计算

Question

我正在尝试使用jAutoCalc插件对数字进行一些计算 没关系，计算正确。

但是当我尝试使用jquery.repeater插件向表中添加行时， 新行不计算在内。 另外，当我删除行表格时，总金额未更新！

有什么帮助吗？

在表中进行任何修改后，您应该调用 autoCalcSetup（）函数。

示例： https://jsfiddle.net/214umqL6/

/** autoCalc **/
$(document).ready(function() {
  function autoCalcSetup() {
    $('table').jAutoCalc('destroy');
    $('table tr').jAutoCalc({
      keyEventsFire: true,
      decimalPlaces: 2,
      emptyAsZero: true
    });
    $('table').jAutoCalc({
      decimalPlaces: 2
    });
  }

  autoCalcSetup();

/** confirm delete row **/

  $('#deleteRow').on('shown.bs.modal', function(e) {
    // store the clicked element as data on the confirm button
    $('#confirmDeleteBtn').data('triggered-from', e.relatedTarget);
  });

  $('#confirmDeleteBtn').click(function() {
    // retrieve the button that triggered the action and use it
    var trigger = $(this).data('triggered-from');
    autoCalcSetup(); // call the function

    $(trigger).closest('tr').remove();
    $('#deleteRow').modal('hide');
  });
});

<div class="repeater">
  <table class="table table-striped table-bordered table-hover mb-0" data-repeater-list="category-group">

        <th>delete</th>
