createElement and checkboxs

[Iain Downie]

Dear List,

I have a snippet of code below that creates a new input element for a
checkbox and sets some attributes.

var observationCheckbox = document.createElement('input');
observationCheckbox.setAttribute('type', 'checkbox');
observationCheckbox.setAttribute('id', 'observation.' + runningCount +
'.species');
observationCheckbox.setAttribute('name', 'observation.' + runningCount +
'.species');
observationCheckbox.setAttribute('value', 's' + speciesCode);

Question: Is it possible to set this checkbox to be 'checked' when it is
created? I'm not sure if this constitutes an attribute or not.

Thanks

Use
var observationCheckbox = document.createElement('input');
observationCheckbox.type = 'checkbox';
observationCheckbox.checked = observationCheckbox.defaultChecked = true;

Use
observationCheckbox.checked = observationCheckbox.defaultChecked = true;

Martin......
