javascript - How do I append list items <li> from an Unordered list <ul> between four other Unordered lists based upon their content -


i have list of brand names dynamically pulled page , need segmented between 4 lists based upon brand name. example 1 column hold begins number. second column hold brands begin letters thru h. third column i-p. fourth column q-z. trying use .map() function in jquery traverse list , pull items out , append respective list having difficulty. appreciated!

(note: not actual brand list... have 50 brands in final list.)

here html:

<div class="brand-directory-body">   <ul class="brand-directory-list" style="display:none;">      <li class="brand">37 signals</li>      <li class="brand">apple</li>      <li class="brand">bmg</li>      <li class="brand">cartoon network</li>      <li class="brand">disney</li>      <li class="brand">enews</li>      <li class="brand">nike</li>      <li class="brand">adidas</li>      <li class="brand">frito</li>      <li class="brand">coke</li>      <li class="brand">adobe</li>      <li class="brand">hostess</li>      <li class="brand">dominoes pizza</li>      <li class="brand">honest co</li>      <li class="brand">z brand</li> </ul> <div class="brand-directory-column">      <h3 class="column-title">#</h3>      <ul class="brand-directory-list-num"></ul> </div> <div class="brand-directory-column">      <h3 class="column-title">a-h</h3>      <ul class="brand-directory-list-ah"></ul> </div> <div class="brand-directory-column">      <h3 class="column-title">i-p</h3>      <ul class="brand-directory-list-ip"></ul> </div> <div class="brand-directory-column">      <h3 class="column-title">q-z</h3>      <ul class="brand-directory-list-qz"></ul> </div> 

var lists = {     numbers: [],     ah: [],     ip: [],     qz: [] };  $('.brand').each(function () {     var letter = $.text(this).substr(0, 1);      if ( /\d/.test(letter) ) {         lists.numbers.push(this);     }     else if ( /[a-h]/i.test(letter) ) {         lists.ah.push(this);     }     else if ( /[i-p]/i.test(letter) ) {         lists.ip.push(this);     }     else if ( /[q-z]/i.test(letter) ) {         lists.qz.push(this);     } });  $('.brand-directory-list-num').append( lists.numbers ); $('.brand-directory-list-ah').append( lists.ah ); $('.brand-directory-list-ip').append( lists.ip ); $('.brand-directory-list-qz').append( lists.qz );

here's fiddle: http://jsfiddle.net/q697n/

if want make code little dryer, can store regular expressions in map object:

var lists = {     numbers: [],     ah: [],     ip: [],     qz: [] };  var map = {     numbers: /\d/,     ah: /[a-h]/i,     ip: /[i-p]/i,     qz: /[q-z]/i }  $('.brand').each(function () {      var el = this, letter = $.text(this).substr(0, 1);      $.each(map, function (key, regex) {         if ( regex.test(letter) ) {             lists[key].push(el);             return false;         }     }); });  $('.brand-directory-list-num').append( lists.numbers ); $('.brand-directory-list-ah').append( lists.ah ); $('.brand-directory-list-ip').append( lists.ip ); $('.brand-directory-list-qz').append( lists.qz );

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)...
