If you refer to a checkbox, you can do it as follows:

HTML example:

<form action="">
<input type="checkbox" id="my_checkbox" value="Bike">Checkbox<br>
</form>

JavaScript:

var myCheckbox = document.getElementById('my_checkbox');
myCheckbox.checked = true;

Accessing within an iframe:

var myFrame = document.getElementById('my_frame');
var myCheckbox = myFrame.contentDocument.getElementById('my_checkbox');
myCheckbox.checked = true;
