如何使用.classList.add("hide");第二次观看时隐藏窗帘

Question

使用 .setAttribute("hidden", true); 时，窗帘保持隐藏状态。 https://jsfiddle.net/g2th3opc/

evt.currentTarget.closest(".inner-container").querySelector(".sliding-panels").setAttribute("hidden", true);

窗帘不要在使用.classList.add("hide");时保持隐藏状态。 https://jsfiddle.net/06vdjka4/

evt.currentTarget.closest(".inner-container").querySelector(".sliding-panels").classList.add("hide");

要复制： 单击 1 svg 播放按钮，然后单击 X。

重复这样做，点击所有的，甚至是你已经点击过的。

您会注意到在使用 .classList.add("hide"); 时窗帘不会隐藏起来。

第二次单击同一个 svg 播放按钮后，窗帘应该保持隐藏状态。

为什么它们不隐藏起来，有解决办法吗？

我尝试post一个片段但是它超出了字符数限制。

您的问题是显示按钮的方式：


  function showAllButtons(buttonSelector) {
    const allButtons = document.querySelectorAll(buttonSelector);

    function showButton(button) {
      // This is where the hide class is getting removed
      button.classList.remove("hide");
    }
    allButtons.forEach(showButton);
  }

  function resetPage() {
    resetBackground("body");
    resetCurtains(".with-curtain");

    // You aren't just matching buttons with this selector. You are matching everything that has been hidden!
    showAllButtons(".hide");

    resetButtons(".outer");
  }

  // This is called whenever an exit button is clicked
  function exitClickHandler(evt) {
    resetPage(); // During this function calls all other .sliding-panels divs are show
    // This only hides the current video's .sliding-panels div
    evt.currentTarget.closest(".inner-container").querySelector(".sliding-panels").classList.add("hide");
  }

解决方案是让您的选择器更具体地取消隐藏按钮：

    // Notice the increased specificity of this selector:
    showAllButtons(".container.hide");

const manageUI = (function makeManageUI() {

  function resetBackground(backgroundSelector) {
    const allBackgrounds = document.querySelectorAll(backgroundSelector);

    function showBackground(background) {
      background.classList.remove("bg1");
    }
    allBackgrounds.forEach(showBackground);
  }

  function resetCurtains(curtainSelector) {
    const allCurtains = document.querySelectorAll(curtainSelector);

    function showCurtain(curtain) {
      curtain.classList.remove("active");
    }
    allCurtains.forEach(showCurtain);
  }

  function showAllButtons(buttonSelector) {
    const allButtons = document.querySelectorAll(buttonSelector);

    function showButton(button) {
      button.classList.remove("hide");
    }
    allButtons.forEach(showButton);
  }

  function resetButtons(buttonSelector) {
    const allButtons = document.querySelectorAll(buttonSelector);

    function showButton(button) {
      button.classList.remove("isOpen");
    }
    allButtons.forEach(showButton);
  }

  function resetPage() {
    resetBackground("body");
    resetCurtains(".with-curtain");
    // Notice the increased specificity of this selector:
    showAllButtons(".container.hide");
    resetButtons(".outer");
  }

Answer 2

只需对退出处理程序执行此小修复。

function exitClickHandler(evt) {
resetPage();

evt.currentTarget
    .closest(".inner-container")
    .querySelector(".sliding-panels")
    .removeAttribute("hidden"); //remove hidden attribute on exit
 }
