如果選中 - > addClass

Question

我輸入複選框

<label for="edit-panes-uc-termsofservice-agreement-checkout-tos-agree-agreed" class="option"><input type="checkbox" class="form-checkbox" value="agreed" id="edit-panes-uc-termsofservice-agreement-checkout-tos-agree-agreed" name="panes[uc_termsofservice_agreement_checkout][tos_agree][agreed]"> I agree with the terms above</label> 

，我想補充類元素befcontentleft 時，將被檢查。告訴我請解決方案。謝謝。

if($('input#edit-panes-uc-termsofservice-agreement-checkout-tos-agree-agreed').is(':checked') { 
    $('befcontentleft').addClass('green'); 
}

    } 
    else { 
     //do something else 
    } 
})
