如何使 JQuery 在 HTA 应用程序中工作

Question

我想将我的 Web 应用程序转换为 HTA 应用程序。

这是我的整个 HTA 文件:

<!DOCTYPE html>
<html lang="en-US">
<HTA:APPLICATION applicationname="Test" border="no" caption="yes" showintaskbar="no" singleinstance="yes" sysmenu="yes" selection="no" innerborder="no" scroll="yes"/>



<head>
<title>Test</title>
<meta http-equiv="x-ua-compatible" content="ie=11"/>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript">

var numRows = 2,
  ti = 5;
var tableCount = 1;
var index = 1;

window.standBy = function() {
  var sum = 0;
  $(".Standby").each(function(index, stand) {
    sum += parseFloat($(stand).val());
  })

  $(".grandtotal").val(sum)
}

function calculate() {
  var tr = $(this).closest('tr');

  var hours = parseInt($(".Time2", tr).val().split(':')[0], 10) - parseInt($(".Time1", tr).val().split(':')[0], 10);
  if (hours < 0) hours = 24 + hours;
  $(".Hours", tr).val(hours);

  if (hours <= 4) $(".Standby", tr).val("0.5");
  if (hours == 4) $(".Standby", tr).val("0.5");
  if (hours > 4 && hours < 8) $(".Standby", tr).val("1");
  if (hours == 8) $(".Standby", tr).val("1");
  if (hours > 8 && hours < 12) $(".Standby", tr).val("1.5");
  if (hours == 12) $(".Standby", tr).val("1.5");
  if (hours > 12 && hours < 16) $(".Standby", tr).val("2");
  if (hours == 16) $(".Standby", tr).val("2");
  if (hours > 16 && hours < 20) $(".Standby", tr).val("2.5");
  if (hours == 20) $(".Standby", tr).val("2.5");
  if (hours > 20 && hours < 24) $(".Standby", tr).val("3");
  if (hours == 24) $(".Standby", tr).val("3");
  if (hours > 24) alert("You cannot exceed a 24 hour period.");



}
$('#table').on('change', ".Time1,.Time2", calculate);
$('#table').find(".Time1").trigger('change')


window.addTime = function() {
  tableCount++;
  $('#timeTable').clone().attr('id', "timeTable" + tableCount).appendTo('#table');
  $('#timeTable' + tableCount).find("input").val("");
  index++;
  $('#timeTable' + tableCount + ' .increment').html(tableCount);

};


$(document).on('click', 'button.removeTime', function() {
  var closestTable = $(this).closest('table');
  if (closestTable.attr('id') != "timeTable") {
    closestTable.remove();
  }
  tableCount--;
  if (tableCount < 1) {
    tableCount = 1;
  }

  standBy();
  return false;
});
</script>
</head>

我还有一个正在运行的 Web 应用程序 JSFiddle，我想将其转换为 HTA 应用程序：https://jsfiddle.net/32u1vuoc/

HTA 文件中 JQuery 的全部功能都可以完美运行，唯一不能运行的是小时计算。这意味着每当我输入待机开始时间和待机结束时间时，总时数和补偿时数都显示为“0”。它不计算任何东西。

我想知道这个社区中是否有人知道解决这个问题的方法。

感谢您的宝贵时间！

您需要在正文之后而不是之前添加脚本，这就是它不起作用的原因。

    }

    window.addTime = function() {

        tableCount = 1;
      }

      standBy();
      return false;
    });
    </script>

    </html>

或者在附加事件处理程序时使用 on document ready，因为现在您尝试将事件添加到 DOM.

中尚不存在的元素

$(document).ready(function(){
  $('#table').on('change', ".Time1,.Time2", calculate);
  $('#table').find(".Time1").trigger('change')
});
