显示对话框以便向HTML表添加新行
Display Dialog Box In Order to Add New Row to HTML Table
所以我目前有一个HTML表，我可以在表的末尾添加行。将出现一个新行，其中包含文本框，您可以输入信息。
然而，我想要取消它并使用一种新方法。我想要它，当单击add row按钮时，会弹出一个dialog box，并为我提供添加行信息的选项。然后它使用validation来确保行是好的，然后将行添加到表中。
我怎么能做到这一点?
你可以看到演示…

你可以使用模态弹出。看看它:如何使用javascript创建一个模态弹出窗口
你必须在那个模态上创建一个单独的div，把所有需要的输入字段放在那个子div中。
所有你需要做的就是触发弹出的"添加行"按钮点击，获得用户输入，关闭弹出窗口，验证代码，并注入到表。
我已经为你写了这段代码，希望对你有所帮助
