<radio-button slot="radio-button" disabled>Tab Targeting</radio-button>
<radio-button slot="radio-button" checked value="yes" name="subtitles">Action Combat</radio-button>
</gameface-radio-group>
Updating the Attributes
You can update the attributes using JavaScript or the DOM APIs.
With JavaScript:
document.querySelector('gameface-radio-group').allButtons[0].<attribute> = <value>;
Where <attribute> ::= disabled | checked | value | name
<value> ::= true | false | string
Custom Buttons
You can add different styles for the radio buttons. Put the custom elements in the radio-button-content
slot:
<gameface-radio-group class="custom-buttons">
<radio-button slot="radio-button" checked>
<div slot="radio-button-content" class="inner-button"><span>OFF</span></div>
</radio-button>
<radio-button slot="radio-button">
<div slot="radio-button-content" class="inner-button"><span>ON</span></div>
</radio-button>
</gameface-radio-group>
You can put HTML elements or other components in the radio-button-content
slot.
Add the controls-disabled
attribute to the <radio-button>
element to hide the default radio button style:
<gameface-radio-group class="custom-buttons">
<radio-button checked controls-disabled>
<div slot="radio-button-content">OFF</div>
</radio-button>
<radio-button controls-disabled>
<div slot="radio-button-content">ON</div>
</radio-button>
</gameface-radio-group>
Usage
On top of using the radioButton.checked
and radioButton.checked
you can
get one of the <gameface-radio-group>
Elements and call radioGroup.allButtons
which will return an Array of all <radio-button>
Elements.
When a radio-button has a checked
attribute, this will be the initially checked
button.
Mouse focusing works as well as keyboard navigation and focusing using the arrow keys and Enter or Space keys.
To select a <radio-button>
using code, you can do the following:
const radioGroup = document.querySelector('gameface-radio-group');
radioGroup.value = {{SOME_RADIO_BUTTON_VALUE}};
If the value you've set doesn't match any of the available radio button values it will return a warning.
Checking Previous or Next Button
You can select adjacent <radio-button>
elements using the <gameface-radio-group>
methods:
checkPrev()
and checkNext()
.
If there are one or more following elements with the disabled
attribute, the methods will check
the next available one.
To select the previous or next available <radio-button>
, you can do the following:
const radioGroup = document.querySelector('gameface-radio-group');
radioGroup.checkNext();
//or
radioGroup.checkPrev();
If there are no available elements to select, the currently checked one will remain selected.
