Checkbox input
[SINCE Orbeon Forms 2016.1]
The
fr:checkbox-input component displays a single checkbox and by default stores a value of true when selected and false when deselected.
NOTE: It differs from the (deprecated in Orbeon Forms 2016.1) Boolean Input field (obtained by binding an
xf:input to a field of xs:boolean type) in that the Checkbox Input displays the label right next to the checkbox.
Appearance
You use
fr:checkbox-input like a regular XForms controls. Example:<fr:checkbox-input ref="initially-open">
<xf:label>Initially Open</xf:label>
</fr:checkbox-input>
The datatype of the bound node is typically
xs:boolean but doesn't have to.The following attributes can be passed:
selected-value: value to store when the checkbox is selected, by defaulttruedeselected-value: value to store when the checkbox is deselected, by defaultfalse
Example:
<fr:checkbox-input
ref="whitespace"
selected-value="trim"
deselected-value="">
<xf:label>Trim leading and trailing spaces</xf:label>
</fr:checkbox-input>
The control works like
xf:select in that it adds and removes the selected value (by default true) into a space-separated list of tokens without affecting other tokens. With the following example, say the bound node initially contains:<whitespace>foo bar</whitespace>
When the user selects the checkbox. The node now contains:
<whitespace>foo bar trim</whitespace>
And when the user deselects the checkbox. The node contains again:
<whitespace>foo bar</whitespace>
NOTE: The control only store a value into the bound node when the user changes the checkbox selection. Say the data by default is blank: the control will not automatically change it to
false (or to the value set by deselected-value) until the user selects then deselects the value again.
