    Reset to default 12

    There is a difference between attributes and properties. To get the attribute, use getAttribute("token").

    Many (predefined) attributes are mapped to properties (or the other way around, I don't know). So for example if you set a cell's colSpan property, you will also affect its colspan attribute.

    However sometimes the two are very different. Most notably, the value attribute of an input will NOT change if you type in the box. However the value property will. This means that you can always reset a textbox with elem.value = elem.getAttribute("value").

    As a general rule, you should always use get/setAttribute to change an elements attributes, because you can't rely on the property being there.

    Side-note: Those "attributes" should be data:

    <a id="buy" data-owner="789" data-token="1000" data-wrapper="purchase" name="oname">

    You'll need to use .getAttribute('token') instead of .token, since "token" isn't a valid HTML attribute.

    <script>
document.write("You Have: ");
document.write(document.getElementById('buy').getAttribute("token"));
</script>
