javascript - 转换不适用于使用 CSS 和 JS 提交的输入类型

Question

我创建了两个按钮 Let's Go! 和 click me。一个是 input type submit，第二个是 anchor tag。anchor 标记 的转换在用户单击它时有效，但 input type submit 在单击时不起作用。

检查下面的脚本。还有其他简单的方法可以解决这个问题吗？

const isMobile = window.navigator.userAgent.match(/Mobile/) && window.navigator.userAgent.match(/Mobile/)[0] === "Mobile";
const event = isMobile ? "touchstart" : "click";
const button = document.querySelectorAll('*[data-animation="ripple"]'),
  container = document.querySelector(".container");
for (var i = 0; i < button.length; i++) {
  const currentBtn = button[i];
  currentBtn.addEventListener(event, function(e) {
    e.preventDefault();
    const button = e.target,
      rect = button.getBoundingClientRect(),
      originalBtn = this,
      btnHeight = rect.height,
      btnWidth = rect.width;
    let posMouseX = 0,
      posMouseY = 0;
    if (isMobile) {
      posMouseX = e.changedTouches[0].pageX - rect.left;
      posMouseY = e.changedTouches[0].pageY - rect.top;
    } else {
      posMouseX = e.x - rect.left;
      posMouseY = e.y - rect.top;
    }
    const baseCSS = `position: absolute;
					width: ${btnWidth * 2}px;
						height: ${btnWidth * 2}px;
						transition: all linear 700ms;
					transition-timing-function:cubic-bezier(0.250, 0.460, 0.450, 0.940);border-radius: 50%;
					background: var(--color-ripple);
				top:${posMouseY - btnWidth}px;
				left:${posMouseX - btnWidth}px;
				pointer-events: none;
				transform:scale(0)`

    var rippleEffect = document.createElement("span");
    rippleEffect.style.cssText = baseCSS;

    //prepare the dom
    currentBtn.style.overflow = "hidden";
    this.appendChild(rippleEffect);

    //start animation
    setTimeout(function() {
      rippleEffect.style.cssText = baseCSS + `transform:scale(1); opacity: 0;`;
    }, 5);

    setTimeout(function() {
      rippleEffect.remove();
      //window.location.href = currentBtn.href;
    }, 700);
  })
}

:root {
  /* if u want to change the color of
	 * the ripple change this value
	*/
  --color-ripple: rgba(255, 255, 255, 0.8);
}

Answer 1

如评论中所述，它不起作用的原因是因为您试图将一个元素附加到 input，这是无法完成的。

一个解决方案是将 input 替换为 button，但您也声明了您不想这样做。

我能想到的唯一其他解决方案是用 span 包装您的 input 并将波纹附加到此 span。效果完成后，解包input。我已在下面的示例中完成此操作。

const isMobile = window.navigator.userAgent.match(/Mobile/) && window.navigator.userAgent.match(/Mobile/)[0] === "Mobile";
const event = isMobile ? "touchstart" : "click";
const button = document.querySelectorAll('*[data-animation="ripple"]'),
  container = document.querySelector(".container");
for (var i = 0; i < button.length; i++) {
  const currentBtn = button[i];
  currentBtn.addEventListener(event, function(e) {
    e.preventDefault();
    const button = e.target,
      rect = button.getBoundingClientRect(),
      originalBtn = this,
      btnHeight = rect.height,
      btnWidth = rect.width;
    let posMouseX = 0,
      posMouseY = 0;
    if (isMobile) {
      posMouseX = e.changedTouches[0].pageX - rect.left;
      posMouseY = e.changedTouches[0].pageY - rect.top;
    } else {
      posMouseX = e.x - rect.left;
      posMouseY = e.y - rect.top;
    }
    const baseCSS = `position: absolute;
					width: ${btnWidth * 2}px;
						height: ${btnWidth * 2}px;
						transition: all linear 700ms;
					transition-timing-function:cubic-bezier(0.250, 0.460, 0.450, 0.940);border-radius: 50%;
					background: var(--color-ripple);
				top:${posMouseY - btnWidth}px;
				left:${posMouseX - btnWidth}px;
				pointer-events: none;
				transform:scale(0)`;

    var rippleEffect = document.createElement("span");
    rippleEffect.style.cssText = baseCSS;

    //prepare the dom
    currentBtn.style.overflow = "hidden";
    var btn = this;
    if (btn.tagName === "INPUT") {
      $(btn).wrap('<span class="ripple-wrap"></span>').after(rippleEffect);
    }
    else {
      btn.appendChild(rippleEffect);
    }

    //start animation
    setTimeout(function() {
      rippleEffect.style.cssText = baseCSS + `transform:scale(1); opacity: 0;`;
    }, 5);

    setTimeout(function() {
      rippleEffect.remove();
      if (btn.tagName === "INPUT") {
        $(btn).unwrap();
      }
      //window.location.href = currentBtn.href;
    }, 700);
  })
}

:root {
  /* if u want to change the color of
	 * the ripple change this value

  --color-ripple: rgba(255, 255, 255, 0.8);
