javascript - 模板文字不能与Bootstrap 4可折叠项目一起使用？

我在js中建立了模板文字，并将其传递给可折叠的项目。只有某些可折叠设备正在工作。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(),

}

最佳答案

您有2期。


您的aria-labelledby都指向相同的ID（带有headingOne1的多个对象），使用uuid heading-$(uuid}将其更改为动态ID。
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。我在ID前面加上i-。


请参见下面的工作示例

//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);
  });
}
