温度计填充动画 svg + jquery

772

我想做一个温度计，这样当你点击复选框时，填充从下往上顺利进行，包括温度计的分区（因此，当复选框被删除时，填充也会顺利进行） . 对如何为此进行填充和固定 jquery 感兴趣。（复选框的工作方式类似于 toogleClass("check")）。

这是我在 Jquery 中搞砸的

$(".analysis-li").click(function(){
    $(this).toggleClass("check");
    var firstStop = document.getElementById('F1gst1');
    percentage = '10%'; firstStop.setAttribute('offset',percentage);
});

有必要使每个检查类的百分比增加，当这个类被移除时，它会再次减少。下面是html和css

<li class="analysis-li"></li>
<li class="analysis-li"></li>
<li class="analysis-li"></li>
<li class="list analysis-li"></li>
<li class="list analysis-li"></li>
<li class="analysis-li"></li>

li.analysis-li 
    margin-bottom: 54px
    position: relative
    padding-left: 20px
    cursor: pointer

    &::before
        position: absolute
        content: ''
        width: 34px
        height: 34px
        left: -34px
        bottom: 3px
        border: #d3ad4b solid 3px
        background-color: transparent
        cursor: pointer
        background-image: url(../img/check.png) 
        background-repeat: no-repeat
        background-position: center
        background-size: 0

    &.check::before
        background-size: 30px

    &:hover::before
        border-color: #c29846
        transition: .3s

这里我整理了一些类似的东西，对不起，没有骑师，我将布局更改为软件，如果不需要，您可以html通过调试器从片段中复制完成的一个

let path = (y, d, extra) => `<path d="${d}" transform="translate(0,${y})" ${extra||''}></path>`
let multi = (count, html) => Array(count).fill(0).map((e, i) => html(i)).join('');
let toggle = el => el.classList.toggle('on') | 
   rect.setAttribute('y', 14.6*(7-document.querySelectorAll("path.on").length)+8)
scale.innerHTML = multi(10, i => path(i*10, 'M60,10h10M65,12h5M65,14h5M65,16h5M65,18h5'));
checks.innerHTML = multi(7, i => path(i*12, 'M10,10v8h8v-8z', 'class="on" onclick="toggle(this)"') +
                                 path(i*12, 'M12,14l2.2,2l2.2,-4'))

g#scale path { 
  stroke: white; 
  stroke-width: 0.7; 
}

#checks { 
  position: absolute; 
  top: 20px; 
  left: 20px; 
}

#checks path {
  fill: none;
  pointer-events: all;
  stroke: #f5b53a;
  cursor:pointer;
  stroke-linejoin:round;
}

#checks path.on + path {
  opacity:1;
}

#checks path:nth-child(2n) {
 opacity: 0;
 pointer-events: none;
 transition: 0.5s;
 stroke: white;
}

<svg viewbox="0 0 135 135" height="90vh" style="background-color:purple">

一般来说，像这样

let move = cb => rect.setAttribute('y', 400 - cb.textContent*50)

document.querySelectorAll('.checkbox')
        .forEach(cb => cb.addEventListener('click', e => move(cb)))

  user-select: none;
}

jQuery 解决方案

这就是我将如何做到的。要为我使用的渐变设置动画requestAnimationFrame。我正在stop为 10% 和 100% 之间的第二个偏移设置动画，但您可以选择您想要的值。

请阅读代码中的注释。

	// Второй stop градиента
 let laststop = document.getElementById('F1gst2');
 // переменная, используемая для переключения анимации
 let n = 0;
 // целевое значение атрибута смещения
 let target;
 // фактическое значение атрибута смещения (offset)
 let val = 10;
 //идентификатор кадра анимации запроса
 let rid = null;

$(".analysis-li").click(function(){
   
   n++;
   // установить целевое значение
   if(n%2 == 1){
     target = 100; 
   }else{target = 10}
    // если есть анимация, то  остановить  
    if(rid){cancelAnimationFrame(rid); rid="null"}
    // вызвать функцию кадра
    frame()      
});


function frame(){
  rid = requestAnimationFrame(frame);
  //расстояние между значением и целевым значением
  dist = target - val;
  //Увеличить значение
  val += dist/10;
  // установить значение offset
  laststop.setAttributeNS(null,"offset",`${val}%`)
}

我通过安装渐变来解决这个问题。如果你有，不要忘记删除 svg 中的样式标签。渐变插入到路径之前的 svg 标签之后。

<linearGradient y2="0%" x2="0%" y1="100%" x1="0%" id="F1g"><stop stop-color="#00FF00" offset="0%" id="F1gst1"/><stop stop-color="#FFFFFF" offset="0%" id="F1gst2"/></linearGradient>

然后，在 offset 的帮助下，我实现了填充百分比。然后是元素个数和选中元素个数的比较。然后给出结果。

var firstStop = document.getElementById('F1gst1');
percentage = '0%';
var CountAllCheckboxes = $('.analysis-li').length;
var CountChecked = 0;

$(".analysis-li").click(function(){
    $(this).toggleClass("check");

    CountChecked = $('.analysis-li.check').length;
    percentage = ((CountChecked / CountAllCheckboxes) * 100)+'%';
    firstStop.setAttribute('offset',percentage);
});
