添加粘滞便笺一个接一个

标签： javascript jquery html html5 css3

在此先感谢，我正在尝试一个接一个地添加粘性图像，如下图所示，但我得到的结果是另一个。最新添加的便利贴应该在最前面，所有其他注释都应该在最新的后面。任何帮助都会受到启发。

定位粘性并将其放入容器中。然后根据left计数分配.sticky值。请查看下面的代码段。

$('#addProblem').click(function() {
  $('.sticky').after('<div class="sticky"><textarea placeholder="Type the problem here..."></textarea><br></div>');
  var stickyCount = $('.sticky').length - 1;
  $('.sticky').each(function() {
    $(this).css('left', stickyCount * 100);
    stickyCount--;
  });
});

这是我的版本

HTML：

<section class="sticky-wrapper">
   <div class="sticky">
   <textarea placeholder="Type the problem here..."></textarea>             
   </div>
</section>
<br/>
<div id="spin_btn_div">
  <div class="btn-container">
  <a class="btn pink pink-button shooter-btn" id="addProblem">Add problem</a>
</div>

CSS 

.sticky-wrapper {
   position: relative;
   min-height: 300px;
}

.pink{
   background:#f05f9d;
   border:1px solid #f05f9d;
   color:#fff;
   font-weight:600;
}

.pink:hover{
   background:#f05f9d;
   border:1px solid #f05f9d;
   color:#fff;
   font-weight:600;
}
.pink-button{
   padding: 10px 11px;
   border-radius: 14px;
   font-weight: 600;
   font-size: 16px;
}
.sticky {
   position: absolute;
   margin: 0;
   padding: 8px 24px;
   width:200px;
   height:200px;
   font-size: 1.4em;
   border:1px #E8Ds47 solid;
   -moz-box-shadow:0px 0px 6px 1px #333333;
   -webkit-box-shadow:0px 0px 6px 1px #333333;
   box-shadow:0px 0px 6px 1px #333333;
   background: #fefdca;
   background: -moz-linear-gradient(top, #fefdca 0%, #f7f381 100%);
   background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#fefdca), color-stop(100%,#f7f381)); 
   background: -webkit-linear-gradient(top, #fefdca 0%,#f7f381 100%);
   background: -o-linear-gradient(top, #fefdca 0%,#f7f381 100%);
   background: -ms-linear-gradient(top, #fefdca 0%,#f7f381 100%);
   filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#fefdca', endColorstr='#f7f381',GradientType=0 ); 
   background: linear-gradient(top, #fefdca 0%,#f7f381 100%);
}
 .sticky p {
   text-align: center;
}
.sticky textarea {
   width:160px;
   height:170px;
   background: #fefdca;
   background: -moz-linear-gradient(top, #fefdca 0%, #f7f381 100%);
   background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#fefdca), color-stop(100%,#f7f381)); 
   background: -webkit-linear-gradient(top, #fefdca 0%,#f7f381 100%);
   background: -o-linear-gradient(top, #fefdca 0%,#f7f381 100%);
   background: -ms-linear-gradient(top, #fefdca 0%,#f7f381 100%);
   filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#fefdca', endColorstr='#f7f381',GradientType=0 );
   background: linear-gradient(top, #fefdca 0%,#f7f381 100%);
   border-bottom:none !important;
}
.sticky ol {
   margin: 12px;
}

JavaScript的：

var zIndex = 0;
var currentXPosition = 0;

$('#addProblem').click(function(){

   zIndex++;

  $('.sticky-wrapper').append('<div class="sticky" style="z-index: ' + zIndex +'; left: 0px"><textarea placeholder="Type the problem here..."></textarea><br></div>');


   $(".sticky-wrapper").find(".sticky:not(:last-child)").each(function (i, item) {
       var itemLeftPos = parseInt(item.style.left || 0);
       currentXPosition = 100; 
       item.style.left = (itemLeftPos + currentXPosition) + "px";
    });

});

注意：我已经添加了类.sticky-wrapper的包装元素。 Link to JSFiddle
