Answer 1

Try this.

To check Radio button using Value use this.

$('input[name=type][value=2]').attr('checked', true); 

Or

$('input[name=type][value=2]').attr('checked', 'checked');

Or

$('input[name=type][value=2]').prop('checked', 'checked');

To check Radio button using ID use this.

$('#radio_1').attr('checked','checked');

Or

$('#radio_1').prop('checked','checked');

Answer 2

The $.prop way is better:

$(document).ready(function () {                            
    $("#radio_1").prop('checked', true);        
});

and you can test it like the following:

$(document).ready(function () {                            
    $("#radio_1, #radio_2", "#radio_3").change(function () {
        if ($("#radio_1").is(":checked")) {
            $('#div1').show();
        }
        else if ($("#radio_2").is(":checked")) {
            $('#div2').show();
        }
        else 
            $('#div3').show();
    });        
});

Answer 3

function rbcitiSelction(e) {
     debugger
    $('#trpersonalemail').hide();
    $('#trcitiemail').show();
}

function rbpersSelction(e) {
    var personalEmail = $(e).val();
    $('#trpersonalemail').show();
    $('#trcitiemail').hide();
}

$(function() {  
    $("#citiEmail").prop("checked", true)
});

Answer 4

If property name does not work don't forget that id still exists. This answer is for people who wants to target the id here how you do.

$('input[id=element_id][value=element_value]').prop("checked",true);

Because property name does not work for me. Make sure you don't surround id and name with double/single quotations.

Cheers!

Answer 5

I've just have a similar problem, a simple solution is to just use:

.click()

Any other solution will work if you refresh radio after calling function.

$("input[name=inputname]:radio").click(function() {
    if($(this).attr("value")=="yes") {
        $(".inputclassname").show();
    }
    if($(this).attr("value")=="no") {
        $(".inputclassname").hide();
    }
});
