【1】、id是唯一的,一个元素只能有一个,不能重复class可以重复
<div> <img src="" width="100%"/> <div class="duihao" id="duihao11"> <img id="duihao1" name='A' src="" /> </div> <div class="duihao" id="duihao22"> <img id="duihao2" name='B' src="" /> </div> <div class="duihao" id="duihao33"> <img id="duihao3" name='C' src="" /> </div> <div class="duihao" id="duihao44"> <img id="duihao4" name='D' src="" /> </div> <div class="duihao" id="duihao55"> <img id="duihao5" name='E' src="" /> </div> <div class="duihao" id="duihao66"> <img id="duihao6" name='F' src="" /> </div> </div> <script> $(function(){ $(".duihao").click(function(){ $(this).children().css("visibility","visible"); var a = $(this).children().attr("name"); setTimeout(function(){ window.location="url?func=cha&pubid={$pubid}&type="+a; },1000); }); }) </script>
