Basic Form Input edit
One of the most common user interface controls in a web form is a simple, one-line text area. In this example we have a very simple form with two input fields. Each input has its own label to the left of the input field.

Program Structure edit
Our program has two parts, a model and a view. The model has instance data in it to store the values that the user enters in the form. The view is part of the presentation in the body of the HTML document.
Sample Program edit
<html
xmlns="http://www.w3.org/1999/xhtml"
xmlns:xf="http://www.w3.org/2002/xforms">
<head>
<title>XForms inputs with labels</title>
<xf:model>
<xf:instance xmlns="">
<data>
<guru/>
<PersonSurName/>
</data>
</xf:instance>
</xf:model>
</head>
<body>
<p>Enter your first name, and last name.</p>
<xf:input ref="PersonGivenName" incremental="true">
<xf:label>Input First-Name:</xf:label>
<xf:hint>Also known as given name.</xf:hint>
</xf:input>
<br/>
<xf:input ref="PersonSurName" incremental="true">
<xf:label>Input Last Name:</xf:label>
<xf:hint>Also known as sur name or family name.</xf:hint>
</xf:input>
<br/>
<br/>
Output First Name: <b><xf:output ref="PersonGivenName"/></b>
<br/>
Output Last Name: <b><xf:output ref="PersonSurName"/></b>
<p>Note that as you type the model output will be updated.</p>
</body>
</html>
Hints edit
You can also provide the user with data entry hints using the <xf:hint> element.
Discussion edit
Notice that as you type, the output gets immediately updated. This is because the XForms input control has an incremental="true" attribute.
Our model is simple, just the first and last name of a person.
Note that the label and hint tags are nested INSIDE the input tags.
