jQuery:Looping all radio buttons inside an HTML table

I have an HTML table having n rows and each rows contain one radiobutton in the Row.Using jQuery , How can i look开发者_Go百科 thru these radio buttons to check which one is checked ?

---

$('#table tbody tr input[type=radio]').each(function(){
 alert($(this).attr('checked'));
});

HTH.

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

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

---

There are many ways to do that, e.g., using .each and the .is traversal method:

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

$('.my-radio-class:checked')

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

$('table input:radio:checked')

Reference: :radio, :checked

---

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

---

$("table tr input[type=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();
