平滑的動畫以進行svg填充

Question

我有一個SVG溫度計，正在嘗試為每個班級順利填充動畫。

我用觸發類來做溫度計。 我正在嘗試為每個班級的上下平滑動畫，以及上下動畫。

 var firstStop = document.getElementById('F1gst1'); percentage = '0%'; firstStop.setAttribute('offset', percentage); 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); });

Answer 1

一種解決方案是僅使用javascript動畫，而不是使用CSS和/或svg-props。 例如：

function anim(fromPercentage) {
   var topLimit = 25;  
   fromPercentage += 1;
   if(fromPercentage < topLimit) {
      $('#F1gst1').attr('offset', fromPercentage + '%');
      setTimeout( function() {
         anim(fromPercentage);
      }, 35);
   }
};

/*
* Animates the bar from 10 to 25 percentage.
* Change the topLimit inside the anim-function to the current desired top level.
* Also tweek the timeout to get smoother transition.
*/
anim(10);

Answer 2

@托馬斯但是我需要這個（（CountChecked / CountAllCheckboxes）* 100）+'％'。 它將有許多遮罩和功能。

這是一個面具和一個功能，這是一個簡短的片段：

 const scale = Array.from(Array(101), (_,i,a) => 90*(100-i)/100); document.querySelector("svg #scale").setAttributeNS(null, "d", scale.filter((v,i) => i && i<100 && i%10 === 0).map(v => `M20,${v},25,${v}`).join("")); setInterval(function(){ let percent = Math.floor(Math.random() * 100); document.querySelector("div").textContent = percent + "%"; document.querySelector("svg #red").style.setProperty("transform", `translateY(${scale[percent]}px)`) }, 1000); 

 svg { max-width: 100px; max-height: 200px; } svg #red { transition: transform 300ms; } 

 <div></div> <svg viewbox="0,0,50,100"> <mask id="myMask"> <line x1=25 y1=5 x2=25 y2=80 stroke="white" stroke-width="10" stroke-linecap="round" /> <circle cx=25 cy=90 r=10 fill="white" /> </mask> <g mask="url(#myMask)"> <rect x=0 y=0 width=50 height=100 fill="#AAA" /> <rect id="red" x=0 y=0 width=50 height=100 fill="red" /> <path id="scale" stroke="#888" stroke-width="0.5" d=""/> </g> </svg>

這是我朋友的解決方案。

var firstStop = document.getElementById('F1gst1');
percentage = '5%'; firstStop.setAttribute('offset',percentage);
var CountAllCheckboxes = $('.analysis-li').length;
var CountChecked = 0;

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

CountChecked = $('.analysis-li.check').length;
percentage = ((CountChecked / CountAllCheckboxes) * 100 + 5)+'%';
$('#g'+CountChecked)[0].beginElement();
setTimeout("firstStop.setAttribute('offset',percentage)", 450);
});
