javascript - 使 onClick 按钮与 div 重叠内容

Question

所以我需要一些帮助来处理按下按钮时页面上的重叠内容。现在我有一个事件按钮的功能，可以帮助我打开和关闭一个 div(div 面板)。我只想知道当按下按钮时，您将如何使这个 div 面板在页面上延伸。

我通过激活我的容器使其与功能重叠一起工作，但我意识到这是完全错误的并且必须更改它。所以现在(正如我之前所说)我有事件按钮。

尝试使用 buttonS 使其通过我当前的功能工作，但实际上没有任何改变。也许一些 z-index？检查代码。

有什么建议吗？

谢谢!

代码如下:

<!--Accordion script-->


var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
  acc[i].onclick = function() {

    this.nextElementSibling.classList.toggle("show");
  }
}


//active container overlap
$('button').click(function(event) {
  $(this).toggleClass('active');

})



//onClose function and refresh function


//var inFormOrLink;
//$('a').on('click', function() { inFormOrLink = true; });
//$('form').on('submit', function() { inFormOrLink = true; });

//$(window).on("beforeunload", function() { 
//return inFormOrLink ? "Do you really want to close?" : null; 
//})

Answer 1

首先你的css有错误，请把body改成这样:

body {
  width: 100%;
  margin: 0 auto;
}

接下来，将您的容器类更改为:

.container {
  width: 100%;
  height: 90%;
  position: absolute;
  margin-top: 2%;
  background-color: #FAF3E9;
}

通过设置 width:100%，每个元素占据其父元素的整个宽度。因此，将 body 和 container 的宽度设置为 100% 应该可以解决您的问题。
