jquery - CSS perspective and translateZ not working properly in FF and Safari -

-

i have created cover flow using css3 perspective , translatez, demo here

it has transition effect when clicking through. works perfect on chrome , ie10, mobile safari 7. however, has few problems on firefox , desktop safari.

  1. on firefox(latest 29.0.1), clicking on image not put 0 position (flat view). cannot click through layers below. when first image current image, cannot click on third 1 directly, unless click second , make current first.
  2. on desktop safari (5, on both pc , mac), transition works partly, not smooth acceptable. main problem no matter image clicks, triggers downloads immediately, while code supposed download when image current one.

structure simple: html

<div class="product-download">     <div id="product-image">         <img src="//placehold.it/360x259" /> <span class="download-title">product image</span>      </div>     <div id="in-situ-image">         <img src="//placehold.it/360x259" /> <span class="download-title">in-situ image</span>      </div>     <div id="product-flyer">         <img src="//placehold.it/360x259" /> <span class="download-title">product flyer</span>      </div>     <div id="data-sheet">         <img src="//placehold.it/360x259" /> <span class="download-title">data sheet</span>      </div> </div>

css

body {     width:100%; } .product-download {     position:relative;     width:900px !important;     height:397px;     margin: 0 auto;     transform: perspective(0px) rotatey(0deg) translatez(0px);     -ms-transform: perspective(0px) rotatey(0deg) translatez(0px);     -moz-transform: perspective(0px) rotatey(0deg) translatez(0px);     -webkit-transform: perspective(0px) rotatey(0deg) translatez(0px);     cursor:pointer;     margin-top:50px;     margin-left:30px; } .product-download > div {     width:360px;     height:289px;     position:absolute;     display:inline-block;     transition: 1s; } #product-image {     z-index:9999;     transform: perspective(0px) rotatey(0deg) translatez(0px);     -ms-transform: perspective(0px) rotatey(0deg) translatez(0px);     -moz-transform: perspective(0px) rotatey(0deg) translatez(0px);     -webkit-transform: perspective(0px) rotatey(0deg) translatez(0px); } #in-situ-image {     transform: perspective(600px) rotatey(-30deg) translatez(-100px);     -ms-transform: perspective(600px) rotatey(-30deg) translatez(-100px);     -moz-transform: perspective(600px) rotatey(-30deg) translatez(-100px);     -webkit-transform: perspective(600px) rotatey(-30deg) translatez(-100px);     z-index:5;     left:150px; } #product-flyer {     transform: perspective(600px) rotatey(-30deg) translatez(-100px);     -ms-transform: perspective(600px) rotatey(-30deg) translatez(-100px);     -moz-transform: perspective(600px) rotatey(-30deg) translatez(-100px);     -webkit-transform: perspective(600px) rotatey(-30deg) translatez(-100px);     z-index:4;     left:330px; } #data-sheet {     transform: perspective(600px) rotatey(-30deg) translatez(-100px);     -ms-transform: perspective(600px) rotatey(-30deg) translatez(-100px);     -moz-transform: perspective(600px) rotatey(-30deg) translatez(-100px);     -webkit-transform: perspective(600px) rotatey(-30deg) translatez(-100px);     z-index:3;     left:510px; } .download-title {     width:300px;     height:30px;     font: italic bold 18px/30px helvetica, serif;     position:absolute;     text-align:center;     display:none; } #product-image >span {     display:block; }

jquery

$('.product-download div').click(function () {     $(this).fadeto('slow').css({         'transform': 'perspective( 0px ) rotatey( 0deg ) translatez(0px)',             '-ms-transform': 'perspective( 0px ) rotatey( 0deg ) translatez(0px)',             '-webkit-transform': 'perspective( 0px ) rotatey( 0deg ) translatez(0px)'     }).css('z-index', '9999');     $(this).prevall().fadeto('slow').css({         'transform': 'perspective( 600px ) rotatey( 30deg ) translatez(-100px)',             '-ms-transform': 'perspective( 600px ) rotatey( 30deg ) translatez(-100px)',             '-webkit-transform': 'perspective( 600px ) rotatey( 30deg ) translatez(-100px)'     }).css('z-index', '1');      $(this).nextall().each(function (index) {         $(this).fadeto('slow').css({             'transform': 'perspective( 600px ) rotatey( -30deg ) translatez(-100px)',                 '-ms-transform': 'perspective( 600px ) rotatey( -30deg ) translatez(-100px)',                 '-webkit-transform': 'perspective( 600px ) rotatey( -30deg ) translatez(-100px)'         }).css('z-index', '-' + index);      });     $('.download-title').css('display', 'none');     $(this).children('span').eq(0).css('display', 'block');     event.preventdefault();      if ($(this).css('z-index') == 9999) {         event.preventdefault();         window.open('//placehold.it/200x200&text=download', '_blank');     } });

your applying z-index: 9999 immediately, why tests true , triggers download (although why varies browser isn't clear).

you could:

  • move z-index declaration fadeto function
  • move if test before transitions (this easiest way)
  • test on other z-index, perhaps use class explicitly identify 'current' item, rather relying on browser implementations of z-indexing

php - render data via PDO::FETCH_FUNC vs loop -

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
