重复加载动画，单击事件 - Raphael Javascript SVG 动画

3

我一直在尝试制作一段 Raphael 动画，它能够正常工作并在加载时进行动画效果，但是... 我希望在点击文本或按钮（位于 Raphael 画布外的 div）后再次播放动画。

Raphael 代码如下：

window.onload = function () { var paper = new Raphael(document.getElementById('frivardihouse'), 250, 250);

function round(value, precision) {
    var multiplier = Math.pow(10, precision || 0);
    return Math.round(value * multiplier) / multiplier;
}

let ltv = 0.6;
let h = 144*ltv;
let y = 86+((1-ltv)*144);
let ltvtxt = round(ltv * 100);


var fillhouse = paper.rect(40.5,230,172.3,0).attr({fill: "#ff6600", stroke: "none"});

var sAnimation = Raphael.animation({ 'width': 172.3, 'height': h, 'x': 40.5, 'y': y, fill: "#ff0066"}, 2000, "backOut")
fillhouse.animate(sAnimation);


var thehouse = paper.path("M236.5,80.4L128.9,2.1c-1.6-1.1-3.7-1.1-5.3,0L16.1,80.4c-3.5,2.6-1.7,8.1,2.6,8.1l13,0c-1,2.5-1.5,5.3-1.5,8.2l0,122.7c0,12,9.2,21.7,20.6,21.7l150.9,0c11.4,0,20.6-9.7,20.6-21.7l0-122.7c0-2.9-0.5-5.7-1.5-8.2h13C238.2,88.6,240,83,236.5,80.4z M206.7,104.9l0,106.5c0,9-6.9,16.3-15.5,16.3l-129.9,0c-8.5,0-15.5-7.3-15.5-16.3l0-106.5c0-9,6.9-16.3,15.5-16.3l129.9,0C199.8,88.6,206.7,95.9,206.7,104.9z").attr({fill: "#ccc", stroke: "none"});
};

我创建了一个示例代码。

我尝试使用常规的单击功能，但似乎无法使其正常工作 :( 什么都没有发生。真的很令人沮丧！

没有 JQuery 也可以实现！

使用 dispatchEvent(new Event('load')); 来触发 JS 中的 onload 事件。

var clickEle = document.getElementsByClassName("clickme")[0];
clickEle.addEventListener("click", function() {
  document.getElementById("frivardihouse").innerHTML = "";
  dispatchEvent(new Event('load'));
});

onload = function() {
  var paper = new Raphael(document.getElementById('frivardihouse'), 250, 250);

  function round(value, precision) {
    var multiplier = Math.pow(10, precision || 0);
    return Math.round(value * multiplier) / multiplier;
  }

  let ltv = 0.6;
  let h = 144 * ltv;
  let y = 86 + ((1 - ltv) * 144);
  let ltvtxt = round(ltv * 100);


  var fillhouse = paper.rect(40.5, 230, 172.3, 0).attr({
    fill: "#ff6600",
    stroke: "none"
  });

  var sAnimation = Raphael.animation({
    'width': 172.3,
    'height': h,
    'x': 40.5,
    'y': y,
    fill: "#ff0066"
  }, 2000, "backOut")
  fillhouse.animate(sAnimation);


  var thehouse = paper.path("M236.5,80.4L128.9,2.1c-1.6-1.1-3.7-1.1-5.3,0L16.1,80.4c-3.5,2.6-1.7,8.1,2.6,8.1l13,0c-1,2.5-1.5,5.3-1.5,8.2l0,122.7c0,12,9.2,21.7,20.6,21.7l150.9,0c11.4,0,20.6-9.7,20.6-21.7l0-122.7c0-2.9-0.5-5.7-1.5-8.2h13C238.2,88.6,240,83,236.5,80.4z M206.7,104.9l0,106.5c0,9-6.9,16.3-15.5,16.3l-129.9,0c-8.5,0-15.5-7.3-15.5-16.3l0-106.5c0-9,6.9-16.3,15.5-16.3l129.9,0C199.8,88.6,206.7,95.9,206.7,104.9z").attr({
    fill: "#ccc",
    stroke: "none"
  });


};

//Trigger onload event while clicking the element
var clickEle = document.getElementsByClassName("clickme")[0];
clickEle.addEventListener("click", function() {
  document.getElementById("frivardihouse").innerHTML = "";
  dispatchEvent(new Event('load'));
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/raphael/2.1.0/raphael-min.js"></script>
<div id="frivardihouse"></div>

<div class="clickme">
  CLICK ME AND REPEAT ANIMATION
</div>

最简单的方法如下所示

在点击事件上调用reFill函数

function reFill() {
  document.getElementById('frivardihouse').innerHTML = '';
  onload();
}

就是这样！

如果你还在寻找答案，我会提供一个与现有方法略有不同的解决方案。基本上我会：

不通过声明全局的onload函数来覆盖onload。这样做会让代码难以跟踪。
将绘制和动画分开成两个方法。
在onload中调用draw方法并获取一个对象。这个对象将执行动画。
onClick将再次调用动画方法。
动画方法将检查房子是否已经填满。如果已经填满，则仅删除填充元素。然后它将执行添加新填充元素的动画。可以查看fiddle链接https://jsfiddle.net/hye0os7f/9/。

function round(value, precision) {
  const multiplier = Math.pow(10, precision || 0);
  return Math.round(value * multiplier) / multiplier;
}
function draw() {
  const paper = new Raphael(document.getElementById('frivardihouse'), 250, 250);

  const ltv = 0.6;
  const h = 144 * ltv;
  const y = 86 + (1 - ltv) * 144;
  const ltvtxt = round(ltv * 100);

  const sAnimation = Raphael.animation(
    {
      width: 172.3,
      height: h,
      x: 40.5,
      y,
      fill: '#ff0066',

let thePaper = null;
const pageOnLoad = function () {

function onRedraw() {

只需使用jquery将点击事件添加到.clickme类。

$('.clickme').click(function(){
    document.getElementById('frivardihouse').innerHTML = '';
    onload();
});

以下是完整的代码

     onload = function () {
        var paper = new Raphael(document.getElementById('frivardihouse'), 250, 250);
        
    function round(value, precision) {
        var multiplier = Math.pow(10, precision || 0);
        return Math.round(value * multiplier) / multiplier;
    }

    let ltv = 0.6;
    let h = 144*ltv;
    let y = 86+((1-ltv)*144);
    let ltvtxt = round(ltv * 100);


    var fillhouse = paper.rect(40.5,230,172.3,0).attr({fill: "#ff6600", stroke: "none"});

    var sAnimation = Raphael.animation({ 'width': 172.3, 'height': h, 'x': 40.5, 'y': y, fill: "#ff0066"}, 2000, "backOut")
    fillhouse.animate(sAnimation);


    var thehouse = paper.path("M236.5,80.4L128.9,2.1c-1.6-1.1-3.7-1.1-5.3,0L16.1,80.4c-3.5,2.6-1.7,8.1,2.6,8.1l13,0c-1,2.5-1.5,5.3-1.5,8.2l0,122.7c0,12,9.2,21.7,20.6,21.7l150.9,0c11.4,0,20.6-9.7,20.6-21.7l0-122.7c0-2.9-0.5-5.7-1.5-8.2h13C238.2,88.6,240,83,236.5,80.4z M206.7,104.9l0,106.5c0,9-6.9,16.3-15.5,16.3l-129.9,0c-8.5,0-15.5-7.3-15.5-16.3l0-106.5c0-9,6.9-16.3,15.5-16.3l129.9,0C199.8,88.6,206.7,95.9,206.7,104.9z").attr({fill: "#ccc", stroke: "none"});
