如何從ID在JavaScript中獲得複選框值

Question

jQuery的

$(document).ready(function(){ 
    $("#cityshow").click(function(){ 
    $("#citybox").toggle(); 
    }); 

    $('#citybox input[type=radio]').click(function(){ 
     var buttonValue = $(this).val(); 
     $("#citybox").toggle(); 
     $('#cityshow').html(buttonValue);

     <div id="cityshow" class="citybox">Sikar</div> 
     <div id="citybox" class="citycollection"> 
     <div style="height:0px; border-bottom:1px solid #333; width:62.5%; margin:0px; float:right "></div> 
     <div style="width:100%; padding:20px 15px;">

      <li><input id="danta" type="radio" name="sikar" value="Danta Ramgarh"> <label for="danta">Danta Ramgarh</label></li> 
      <li><input id="sikar" type="radio" name="sikar" value="Sikar"> <label for="sikar">Sikar</label></li>

     </div>

如何從id得到的值在JavaScript/jQuery的？

Answer 1

使用.val()

$('#yourid').val(); 

Answer 2

此外，這是真正的好：

$('#yourid').is(':checked'); 

對於語義，這個人是更廣泛的應用。
