使用CSS attribute selector,input[value="green"]
,获取.querySelectorAll()
的所有人。它将生成一个数组,因此您可以读取其length
属性。
更具体地说,您也可以将其与[type="radio"]
结合使用:
input[type="radio"][value="green"]
<强>更新:强>
根据要求,要选中仅选中,请使用CSS :checked
input[value="green"][type="radio"]:checked
console.log(document.querySelectorAll('input[value="green"][type="radio"]:checked').length)
<tr id="1">
<td style="color : blue;"><b>President Staff</b></td>
<td class="text-center" style="padding-left:40px;"><input type="radio" class="form-check-input" name="jabatan1" value="green" onClick="green('1')" required></td>

</tr>

使用@wscourge提到的Document QuerySelector属性尝试此操作, 这将记录选定的绿色和红色无线电
location /apis/master/ {
# Reroutes /apis/master/* to /apis/FreeTierSmall/master/* correctly!
proxy_pass http://localhost:80/apis/FreeTierSmall/master/;
}
&#13;
window.addEventListener("load", function() {
var radioOption = document.querySelectorAll('input[type=radio][name^="jabatan"]');
radioOption.forEach(function(e) {
e.addEventListener("click", function() {
console.clear();
console.log('Green : ' + document.querySelectorAll('input[type=radio][value="green"]:checked').length + '\nRed : ' + document.querySelectorAll('input[type=radio][value="red"]:checked').length);
});
});
});
