Javascript 遍历div中的元素

发布于10月01日

新的脚本，所以请善待我.

我试图循环遍历"包装器"类中的所有元素，以x时间显示每个元素.此代码仅一次显示所有元素.

      <p>Testing</p>
    </div>
  </div>

</body>

JavaScript

var divOne = document.getElementsByClassName('x')
console.log(divOne.length)


for (let i=0, len = divOne.length; i < len; i++) {
  setTimeout(() => {
    divOne[i].style.display = 'none';
  }, 5000)
}

推荐答案

原因是由于以下代码

  setTimeout(() => {
    divOne[i].style.display = 'none';
  }, 5000)

这会使所有元素在5000毫秒后隐藏，因此您需要严格设置它们

var divOne = document.getElementsByClassName('x')


for (let i=0, len = divOne.length; i < len; i++) {
  setTimeout(() => {
    for(let j=0;j<len;j++){
        if(j==i){
            divOne[j].style.display = 'inline-block';
         }else{
            divOne[j].style.display = 'none';
         }
     }
  }, 5000*i)
}

.x{
  display:none;
}
