css - Jquery to change div background color when radio button selected? -


i have 2 separate sets of radio buttons , want its' divs' color change when selected. behavior want quite straightforward, if radio button selected, corresponding div should change color. (and change original color if deselected).

however, issue if radio button in set selected, first set's div changes original color though 1 of radio buttons still selected. how fix this?

see demo here

jquery used:

$(document).ready(function(){     $('input:radio').change(function(){         $('div.highlight').removeclass('highlight');         $(this).closest('div').addclass('highlight');     }); });

for 2nd issue need wrap your's inputs block separate wrapper , change bit of code..

js

$(document).ready(function(){     $('input:radio').change(function(){         var $this = $(this);         // remove class in specific `box` contains radio         $this.closest('.box').find('div.highlight').removeclass('highlight');         $this.closest('.q').addclass('highlight');     }); });

html

<div class="box"> 1st set     <div class="q">         <input type="radio" id="1" name="11" />         <label 1>a</label>     </div>     <div class="q">         <input type="radio" id="2" name="11" />         <label 2>b</label>     </div> </div> <div class="box">     <hr> 2nd set     <div class="q">         <input type="radio" id="3" name="22" />         <label 3>a</label>     </div>     <div class="q">         <input type="radio" id="4" name="22" />         <label 4>b</label>     </div> </div>

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
