jquery – 使用html和css创建动态Tank level / meter

我目前在项目中创建“储罐计量系统”时遇到了问题.我正在使用MVC并使用以下标记,我已经实现了这个：

通过使用：

#container {
    position:absolute;
    margin:0;
    margin-top:-50px;    
    width:100%;
    padding:0;    
    -moz-perspective: 1000px; /*required to make cylinder shape*/
    -webkit-perspective: 1000px;
}
#frame {
    -moz-transform-style: preserve-3d;
    -webkit-transform-style: preserve-3d;
    margin-left:5%;
    -moz-transform: rotateX(0deg) rotateY(0deg) rotateZ(0deg) translate3d(40%,60px,175px);
    -webkit-transform: rotateX(0deg) rotateY(0deg) rotateZ(0deg) translate3d(40%,175px); 

}
.strip {
    -moz-transform-style: preserve-3d;
    -webkit-transform-style: preserve-3d
}
.strip div {
    position: fixed;
    background-repeat:repeat;
    border-width: thin 10px;
    color:#ececec;
    vertical-align:central;
    height:130px; /*height and width of tank display*/
    width:12%;
    background-color:rgba(128,128,0.99);
    -webkit-border-bottom-right-radius: 2px;
-webkit-border-bottom-left-radius: 2px;
-moz-border-radius-bottomright: 2px;
-moz-border-radius-bottomleft: 2px;
border-bottom-right-radius: 2px;
border-bottom-left-radius: 2px;

-webkit-Box-shadow: inset 0px -35px 20px -37px rgba(0,0.96);
-moz-Box-shadow: inset 0px -35px 20px -37px rgba(0,0.96);
Box-shadow: inset 0px -35px 20px -37px rgba(0,0.96);
}
.strip div:before {
    content:"";
    position: absolute;
    z-index: -1;
    /*Make this lower so any text appears in front*/

    top: 0;
    right: 0;
    bottom: 50%; /*used for tank level setting*/
    left: 0;
    background: rgba(56,56,0.8);

但是,我现在期待它变得动态. (即浅灰色等级根据’.a’条带内的值而变化(在这种情况下为50％).

我用的是：

var test = $('#tank1FrameA').text(); //gets value of first tank
        test = parseInt(test);

得到50提取.

但是,由于我无法定位：beforepseudo元素来编辑’高度/等级’,我还能如何实现这种平衡/动态能力？

一般来说;

+-------------+
|    50%      | <-- value to use
|             |
+-------------+ <-- this level should change
|             |
|             |
+-------------+

为25％：

+-------------+
|    25%      | <-- value to use
|             |
|             |
+-------------+ <-- this level should change
|             |
+-------------+

等等

有关这种圆柱形状如何完成的任何建议？

Here是一个可运行/可编辑的jsfiddle.

最初创建时

坦克,我正在寻找编辑：

.strip div:before {

为了达到这个目的,我们的底层属性.

但是,我最近发现伪元素不是DOM的一部分,因此JQuery无法访问(尽管它可能很强大).

解决方法

如果你只需要填充坦克,你可以使用一个更简单的结构来构建具有两个HTML元素,border-radius和一个伪元素的坦克.

然后,您可以使用JS根据在.tk div的自定义数据属性数据量中输入的值更改绿色区域的高度：

DEMO(更改.tk div中自定义数据属性data-amount的值以更改液体的高度).

var amount = $('.tk').attr('data-amount'),height = amount * 80/100 + 20;

$('.lq').css({height : height + '%'});

.tk{ /*Liquid Section*/
    position:relative;
    width:40%; 
    height:130px;
    padding-top:50px;
    margin: 0 auto;
    background:rgba(56,0.8);
    border-radius: 100%/40px;
    border-bottom:3px solid #000;
    text-align:center;
    z-index:1;
    overflow:hidden;

}
.tk:after,.lq{
    content:'';
    position:absolute;
    top:0; left:0;
    width:100%;
    height:20%;
    z-index:-1;
}
.lq{
    background:rgba(128,0.99);
    height:80%;
    top:-2px;
    border-radius:100%/40px;
    border-bottom:3px solid #000;
}
.tk:after{
    height:20%;
    border:1px solid #000;
    border-radius:100%; /*makes circle at top*/
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="tk" data-amount="40">
    40%
    <div class="lq"></div>
</div>
