模板文字不适用于 Bootstrap 4 可折叠项目？

Question

我在 js 中构建了一个模板文字，并将其传递给一个可折叠项目。只有一些可折叠物在工作。知道为什么会这样吗？

//Generates a random number for div id
function uuidv4() {
  return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function (c) {
    var r = Math.random() * 16 | 0, v = c == 'x' ? r : (r & 0x3 | 0x8);
    return v.toString(16);
  });
}


//Exhibitors
const qaList = [
  { 
    faqId: uuidv4(),
    question: "Item 1",
    answer: "Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch."
  },
  { 
    faqId: uuidv4(),
    question: "Item 2",
    answer: "Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch."
  },
  { 
    faqId: uuidv4(),
    question: "Item 3",
    answer: "Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch."

    question: "Item 6",
    answer: "Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch."
  }  
];


function qaTemplate(faq) {
  return `

}

document.getElementById("accordionEx").innerHTML = `${qaList.map(qaTemplate).join(' ')};`

Answer 1

您有 2 个问题。

您的 aria-labelledby 都指向同一个 ID（多个对象带有 headingOne1）已使用 uuid heading-$(uuid}.
您的 uuid 生成器正在生成以数字开头的 id。这不是有效的 html ID。我用 i-.

请参阅下面的工作示例

//Generates a random number for div id
function uuidv4() {
  return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function (c) {
    var r = Math.random() * 16 | 0, v = c == 'x' ? r : (r & 0x3 | 0x8);
    return v.toString(16);
  });
}
