## Input Checked Attribute
|
||
|
|
|
||
|
|
The checked attribute is a boolean attribute.
|
||
|
|
|
||
|
|
When present, it specifies that an <input> element should be pre-selected (checked) when the page loads.
|
||
|
|
|
||
|
|
The checked attribute can be used with <input type="checkbox"> and <input type="radio">.
|
||
|
|
|
||
|
|
The checked attribute can also be set after the page load, through JavaScript.
|
||
|
|
|
||
|
|
## Take a look at the following example:
|
||
|
|
```html
|
||
|
|
<form action="/action_page.php">
|
||
|
|
<input type="checkbox" name="vehicle" value="Bike"> I have a bike<br>
|
||
|
|
<input type="checkbox" name="vehicle" value="Car" checked> I have a car<br>
|
||
|
|
<input type="submit" value="Submit">
|
||
|
|
</form>
|
||
|
|
```
|
||
|
|
|
||
|
|
In the example above when the web page is loaded by default the first checkbox will come automatically selected due to the checked attribute.
