Jquery gets an instance of a radio value

This article is an example of how to get the value of radio from jquery. The details are as follows:

Radio group:

$("input[@type=radio][@checked]").val();

Radio group:

$("input[@type=radio]").attr("checked",'2');// Set up the value=2 Is the currently selected item 

Gets the values of a set of selected items of radio

var item = $('input[@name=items][@checked]').val();

The second element of the radio radio group is the currently selected value

$('input[@name=items]').get(1).checked = true

The old version of jquery

var_name = $("input[@name='radio_name']:checked").val();

Jquery 1.3 later

var_name = $("input[name='radio_name']:checked").val();

Get a jquery instance of the radio value:

function getra(){
var_name = $("input[name='isspecialcnt']:checked").val();

//alert(var_name);

if(var_name=='1'){

$("#isspecialcntyes").show();

$("#isspecialcntno").hide();

}

if(var_name=='0'){

$("#isspecialcntyes").hide();

$("#isspecialcntno").show();

}

}
