jQuery獲得谷歌驗證碼的值詠歎調檢查

我怎樣才能從詠歎調查的屬性值爲假？我想檢查詠歎調檢查真或假。jQuery獲得谷歌驗證碼的值詠歎調檢查

我試過，但不起作用：

console.log($("#recaptcha-anchor").attr("aria-checked").val());

使用'$（ '：複選框'）。ATTR（ '詠歎調覈對'）'刪除'.VAL（） '它不是一個值它是一個attr – guradio

它的一個不是一個checbox，我想檢查 – Bas

更新答案 – guradio

console.log($('#recaptcha-anchor').attr('aria-checked'))

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<span class="recaptcha-checkbox goog-inline-block recaptcha-checkbox-unchecked rc-anchor-checkbox" role="checkbox" aria-checked="false" id="recaptcha-anchor" tabindex="0" dir="ltr" aria-labelledby="recaptcha-anchor-label">

刪除.val()它不是一個值，它是一個屬性。
使用$(':checkbox').attr('aria-checked')

更新

返回undefined console.log（$（「：checkbox」）。attr（'aria-checked'）） ;它的一個範圍 – Bas

'$（「spanidhere」）。attr（'aria-checked'）'使用這個。更新答案@Bas – guradio

仍然得到未定義的console.log（$（'＃recaptcha-anchor'）。attr（'aria-checked'））; @guradio – Bas
