There are many ways to do that, e.g., using .eachand the .istraversal method:

有很多方法可以做到这一点，例如使用.each和.is遍历方法：

$("table tbody tr td input[name=something]:radio").each(function() {
    if($(this).is(":checked")) {
        $(this).closest("tr").css("border", "1px solid red");
    } else {
        // do something else
    }
});

To loop through all the radio checked radio buttons, you can also do this:

要遍历所有选中的单选按钮，您还可以执行以下操作：

$('input:radio:checked').each(function() {
    //this loops through all checked radio buttons
    //you can use the radio button using $(this)
});

Do you want to process every radio button or do you only need the checked ones? If the latter, it is quite easy:

您是要处理每个单选按钮还是只需要选中的单选按钮？如果是后者，那就很容易了：

$('table input:radio:checked')

Reference: :radio, :checked

参考：:radio，:checked

var checked = $('#table :radio:checked');

//get the checked radio input, put more specificity in the selector if needed
var $checkedRadio = $("input[type=radio]:checked");

//if you want the value of the checked radio...
var checkedRadioVal = $checkedRadio.val();
