AppML HTML Forms

With AppML, the <htmlform> element defines an HTML form.

HTMLForm Sub Elements

The <htmlform> element can have the following sub elements:

• title
• stylesheet
• script
• onload
• commands
• sql
• elements
• header
• form
• footer

The Title Element

An AppML <title> element inside an <htmlform> element has the same function as the title element inside the <appml> element.

If this element is omitted the application will use the default title from the <appml> element.

The Stylesheet Element

An AppML <stylesheet> element inside an <htmlform> element has the same function as the stylesheet element inside the <appml> element.

If this element is omitted the application will use the default stylesheet from the <appml> element.

The Script Element

The AppML <script> element provides a method for adding standard HTML scripts to the application.

Any legal script code can go inside the <script> element.

Example:

<script type="text/javascript">

<!--
function message()
{
alert("This alert box was called with the onload event")
}
// -->

</script>

The Onload Element

The AppML <onload> element defines a script to be executed when the AppML application loads in a browser.

This example will execute the Javascript "message()" when the AppML page loads.

<onload>javascript:message()</onload>

The Commands Element

The AppML <commands> element provides a method for substituting the standard AppML commands with another set of commands.

Example:

<commands>

<input type="button" class="cmd"
onclick="javascript:db_putrecord('update')"
value="Submit" />

<input type="button" class="cmd"
onclick="javascript:db_putrecord('delete')"
value="Delete" />

</commands>

The SQL Element

The AppML <sql> element defines the SQL statement to be used to extract data from the database.

If this element is omitted, the input form will use the default <sql> element from database description.

The Header Element

The AppML <header> element is used to define an additional output that will be displayed before the actual input form on a page.

Any HTML code may be included inside the <header> element.

The Footer Element

The AppML <footer> element is used to define an additional output that will be displayed after the actual input form on a page.

Any HTML code may be included inside the <footer> element.

The Elements Element

The <elements> element can have the following sub elements:

• required
• submit
• type
• format
• value
• onchange

The Form Element

The AppML <form> element is used to define the layout of the input form. If this element is omitted, a default layout is used.

Any legal HTML form elements can be put inside the <form> elements. If this element is used, each input field inside the form must have an id attribute that corresponds with the name of the data fields in the underlying recordset.

Example:

<htmlform>

<sql>
Select CompanyName,ContactName,City from Suppliers
</sql>

<form>
<table class='input' width='100%'>
<tr>
<td valign='center'>Company Name</td>
<td>
<input size='41' id='companyname' value='' />
</td>
</tr>
<tr>
<td valign='center'>Contact Name</td>
<td>
<input size='31' id='contactname' value='' />
</td>
</tr>
<tr>
<td valign='center'>City</td>
<td>
<input size='16' id='city' value='' />
</td>
</tr>
</table>
</form>

</htmlform>

HTMLForm Attributes

The <htmlform> element has the following attributes:

• name
• src
• new
• delete

The Name attribute

The name attribute is used to name the <htmlform> element. This enables an AppML Form Service to run a number of different input forms from the same AppML description.

Example:

<htmlform name="Suppliers">

The Src attribute

The src attribute provides a reference to an <htmlform> element stored in an external AppML description file.

Example:

<htmlform name="Suppliers" src="suppliers_input">

The New and Delete attributes

The new and delete attribute can be used to disable the NEW and DELETE buttons from the AppML HTML Form.

Example:

<htmlform new="false" delete="false">
