Can I write this javascript more efficiently with jquery?

Question

Do you think jquery could help me get the following script work faster? Thanks!

window.onload=function colorizeCheckedRadios(){                     
    var inputs = document.getElementsByTagName("input");
    if (inputs) {
        for (var i = 0; i < inputs.length; ++i) {
            if(inputs[i].checked&&inputs[i].type=="radio"){
                inputs[i].parentNode.parentNode.style.backgroundColor='#FCE6F4';
            }
        }       
    }
}

Faster, I don't know. Cleaner and cross browser: yes

$(function() {
    $('input:radio:checked').parent().parent().css('background-color', '#FCE6F4');
});
