Submit initial selection in dropdown list

I have a dropdown list which runs the javascript function printResult when the default selection is changed:

<form action="">
<select name="list" onChange="printResult();">
    <option value="1"> Option 1</option>
    <option value="2" selected> Option 2</option>
    <option value="3"> Option 3</option>
</select>
</form>

I would like the form to submit the option that is selected as default when the page loads, as well as when another option is selected. All tutorials I can find only cover onchange, rather than what I want.

Is this possible?

Solution

if you want to call a function on page load do this:

<body onload="printResult();">

<form action="">
<select name="list" onChange="printResult();">
    <option value="1"> Option 1</option>
    <option value="2" selected> Option 2</option>
    <option value="3"> Option 3</option>
</select>
</form>
</body>

or in jquery you can postpone the load function anywhere in the page :

$(window).on("load",function(){ printResult(); })

or on document ready:

$(document).ready(function(){printResult();})
