The <htmlform> element contains the elements of an HTML form.
<htmlform>元素嵌套了HTML表单元素。
The <htmlform> Element
<html>元素
By adding an <htmlform /> element after the <database> element, the AppML Form Service will generate an HTML input form based on the SQL defined in the <database> element. An empty record will be displayed, ready to be filled with data. New/Submit/Delete buttons will automatically be added.
通过在<database>元素之后添加一个<htmlform />元素，该AppML报告服务将产生一个基于定义在<database>元素中SQL的HTML报告；将显示一个空记录，可以在其中书写数据； “New [新添] / Submit [提交] / Delete [删除] ”按钮将会自动被添加进去。
Note: When working with HTML lists and forms, the <keyfield> and <maintable> elements must be presented in the <database> element:
注意：当与HTML列表和表单一起运行时，<keyfield> 和 <maintable>元素必须存在于<database>元素：
<?xml version="1.0" ?> <appml> <database> <htmlform /> </appml> |

However, when working with data, it is more probable that the user wants to see the data in a list and have the opportunity to modify existing data and add new data to the database. Therefore we add the <htmllist> element. The user will now view the data in a list, but a folder image is added to the left of each record. An input form will open when clicking on the folder image. The user may now modify the data or enter new records (by clicking on the new button in the list OR in the input form):
然而，当伴随数据运行时，大多数用户都希望看到列表中的数据，并且，他们都希望修改现存的数据，并向数据库中添加新数据。因此，我们添加<htmllist>元素。用户将在列表中查看数据，文件夹图像将被放置到每条记录的左边。当点击文件夹图像时，将会打开一个输入表单。用户将可以修改当前数据或输入新的记录（通过点击输入表单中列表的“新添”按钮）：
<?xml version="1.0" ?> <appml> <database> <htmllist /> </appml> |
