php - 如何选中/取消选中单个单选按钮

Question

$('.ssn_byphone').click(function(){
    var ssn_role = document.getElementById('ssn_byphone').checked;                     
    if(ssn_role==true)
    {
        $('#ssn-div').hide();
        $('.ssn_byphone').css('display','block');
        $('#ssn').val('');
    }
    else
    {
        $('#slideUp').show();
    }
});

<input id="ssn_byphone" class="ssn_byphone" type="radio" name="pi[ssn_byphone]" value="Yes"><label for="radio1"> I will provide SSN by phone</label>

我想在单击此单选按钮时选中/取消选中它，并相应地设置条件。

试试这个:

var checked=false;
$('.ssn_byphone').click(function(){
    checked=!checked;
    $(this).prop("checked",checked);
    if($(this).is(':checked'))
    {
        $('#ssn-div').hide();
        $('.ssn_byphone').css('display','block');
        $('#ssn').val('');
    }
    else
    {
        $('#slideUp').show();
    }
});

<input id="ssn_byphone" class="ssn_byphone" type="radio" name="pi[ssn_byphone]" value="Yes"><label for="radio1"> I will provide SSN by phone</label>
