JavaScript & Checkboxes - More efficient way of storing values of each checkbox?

Is there a more efficient way of storing my checkbox values?

Each checkbox has an assigned value, I was wondering if there was a better way of storing these links? (for scalability when there are many checkboxes)

HTML page extract:

    <form>
        <label for="checkbox1">Link #1</label>
        <input type="checkbox" id="checkbox1" value="http://ift.tt/1BrEgTq">
        <label for="checkbox2">Link #2</label>
        <input type="checkbox" id="checkbox2" value="http://ift.tt/1N89zEu">
        <label for="checkbox3">Link #3</label>
        <input type="checkbox" id="checkbox3" value="http://ift.tt/1BrEk5y">

        <input type="button" value="open links" id="open_link"/>
    </form>

Javascript file extract:

$("#open_link").click(function() {
    performOpenLink();
})

function performOpenLink(){
$("input[type=checkbox]").each(function() {
        if (this.checked) {
            window.open(this.value)
        }
    });
}
