Question

I have a multiple rows of radio boxes like this

<input id="m_0" type="radio" value="m" name="c_0">
<input id="f_0" type="radio" value="f" name="c_0">

<input id="m_1" type="radio" value="m" name="c_1">
<input id="f_1" type="radio" value="f" name="c_1">

<input id="m_2" type="radio" value="m" name="c_2">
<input id="f_2" type="radio" value="f" name="c_2">

So, I want to validate if the radio has been selected in each row

I tried this way – if ($('input:radio[name="c_"+i]:checked').val()) {

where i = 0,1,2… but it didn’t work

any idea how can I change it to work? thanks.

val returns a string which is always true, you should use length property instead:

if ($('input:radio[name=c_'+i+']:checked').length) {

Note that you are concatenating the variable’s value incorrectly.
