包含DIV到“;封面“;包含元素

Containing DIV to "cover" contained elements

本文关键字:包含 元素 封面 DIV      更新时间:2023-09-26

我有这样的HTML:

<div id="cover" on-tap="_overlayTapped" class$="{{status}}">
  <form method="POST" action="/some/action">
    <input required id="name" name="name" label="Your name"></input>
    <input required id="surname" name="surname" label="Your name"></input>
    <button type="submit">Click!</button>
  </form>
</div>

我想添加Javascript或样式,以便div #cover将:

1) 模糊其内容。例如,当表单加载(通过AJAX)一些默认值时,我希望包含的内容"模糊"(我想是#container的不透明度),但我也不希望人们能够点击字段。

2) 将#cover转换为"模态",这意味着点击它将有效地等待点击以尝试重新加载数据(如果调用失败)

使用"包含"div是否实际上不可能做到这一点?我意识到,当我点击一个字段时,事件就会出现在字段本身,然后它就会冒泡到容器中。。。我是不是搞错了?

我不太确定你想做什么,但我为你做了这个,请检查这是否是你想要的。单击按钮打开模态,它框将出现,其他内容将变模糊。

这是代码:

// Get the modal
var modal = document.getElementById('myModal');
// Get the button that opens the modal
var btn = document.getElementById("myBtn");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks the button, open the modal
btn.onclick = function() {
    modal.style.display = "block";
document.getElementById("blurit").style.filter = "blur(4px)";
    document.getElementById("blurit").style.WebkitFilter = "blur(4px)";
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
    modal.style.display = "none";
document.getElementById("blurit").style.filter = "blur(0)";
    document.getElementById("blurit").style.WebkitFilter = "blur(0)";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
    if (event.target == modal) {
        modal.style.display = "none";
document.getElementById("blurit").style.filter = "blur(0)";
    document.getElementById("blurit").style.WebkitFilter = "blur(0)";
    }
}
/* The Modal (background) */
.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 100px; /* Location of the box */
    left: 0;
    top: 0;
    width: 100%; /* Full width */
    height: 100%; /* Full height */
    overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0,0); /* Fallback color */
    background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}
/* Modal Content */
.modal-content {
    background-color: #fefefe;
    margin: auto;
    padding: 20px;
    border: 1px solid #888;
    width: 80%;
}
/* The Close Button */
.close {
    color: #aaaaaa;
    float: right;
    font-size: 28px;
    font-weight: bold;
}
.close:hover,
.close:focus {
    color: #000;
    text-decoration: none;
    cursor: pointer;
}
