javascript - 附加的新行不像前一行(行)




jquery html-table (2)

您可以在此案例标记中指定元素选择器目标。 创建新的DOM元素后,必须再次添加侦听器。

我有一个HTML表格,我有几个 td 作为 input 字段,我的表是动态的,当页面加载我附加到我的表的第一行,并 focus 于第一个输入字段,在我的情况下,即 Item Name

我的行中有3个输入字段,分别是 Item NameUnit QtyDisc%

  • 当用户在 ItemName 输入字段中单击时,我正在从数组中搜索项目名,该数据是数组中的对象以填充项目名称
  • 选择 Item NAme 我将我的焦点移动到下一个输入字段,即 Unit Qty 然后将焦点转移到下一个输入字段,即之间的一些计算中的 Disc% ,以计算 Total Amount
  • 然后,当用户从 Disc% 焦点出来时,我正在追加一个新行,实际上我有一个函数,其中我有代码来附加行,所以我在焦点上调用该函数的 Disc%
  • 在焦点离开 Disc% 我希望我的焦点应该转到新行的 ItemName ,并且应该表现得像它的行为(就像从数据中搜索一样)等等

我已经评论了代码中的行,以便更好地了解用户在哪里发生的事情

在我身边,我认为我使用错误的方法来完成这项任务

注意: - 在将来每次关注时我可能会做一些计算,所以请以这种方式帮助我

我提供了所有信息,如果还不够,那么你们都可以在评论中问我

编辑

根据 Wils's 回答,从 Disc% 焦点出来后,新行正在追加,焦点也会转移到新行的 Item Name 但问题是当新行附加时, autocomplete 在第一行中最初没有工作当页面加载时我在 Item Name 输入字段包含 m 所有项目名称显示为下拉列表但第二行未显示

有人在这里请帮帮我


您的代码有几个问题

最重要的两个是

  • 您使用具有相同 id 多个元素。 但是 id 必须是唯一的。 如果多个元素具有相同的(CSS不同),JavaScript / jQuery将始终使用带有id的第一个元素。 我在这里用 name 而不是 id
  • 您可以向元素添加事件侦听器,这些元素在运行时不存在。 当您收听 focusout 事件时,仅创建第一个输入行。 我在整个文档上听取 focusout 事件。 如果您关注输入,事件将冒泡到 document ,我根据事件的 target 属性决定做什么。

我重新编写了一些代码并进行了一些改进,但它远非完美。
