-

i realized there bug jquery draggable in chrome, doesn't exist in firefox , internet explorer. have div #drag-container /450x80/ , 3 draggable objects inside. /150x0/ , when move them lowest point ,let them , drag again lower position 0,80 + 14 = 0,94 px. let them , drag , 14 px lower again.

is there fix ?

working demo: http://jsfiddle.net/ucmqq/ here code:

<style>     .draggable { width: 150px; height: 0px; cursor:move; }     <?php if($userinfo->use_colors != '0'): ?>     #drag-container { width: 450px; height:80px; background-color:<?=$userinfo->background?>; }     <?php else: ?>     #drag-container { width: 450px; height:80px; background:url(/backgrounds/<?=$userinfo->image?>); }     <?php endif; ?>     </style>      <script language="javascript">      $(function() {         $( "#draggable" ).draggable({ cursor: "move",containment: 'parent', scroll: false,         stop: function() {         document.settings.np_x.value = $(this).css('left');         document.settings.np_y.value = $(this).css('top');          }                                     });         $( "#draggable2" ).draggable({ cursor: "move",containment: 'parent', scroll: false ,         stop: function() {         document.settings.artist_x.value = $(this).css('left');         document.settings.artist_y.value = $(this).css('top');          }                                      });         $( "#draggable3" ).draggable({ cursor: "move",containment: 'parent', scroll: false ,         stop: function() {         document.settings.other_x.value = $(this).css('left');         document.settings.other_y.value = $(this).css('top');          }                                      });     });      </script>   <div id="drag-container">     <div id="draggable" class="draggable" style="position:relative;top:5px;left:80px;">         .::[ nowplaying signature ]::.     </div>     <div id="draggable2" class="draggable" style="position:relative;top:25px;left:80px;">         artist - title     </div>     <div id="draggable3" class="draggable" style="position:relative;top:45px;left:80px;">         album: (year)         <br>         genre:     </div>  </div>

the problem height of draggable object 0. height 1 again it's buggy, without height @ it's ok.

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
