Question

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，我希望包含的内容是＆＃34;模糊＆＃34; （我想#container的不透明度）但我也不希望人们能够点击字段。

2）将#cover变成＆＃34; modal＆＃34;，意味着点击它会有效地等待点击以尝试重新加载数据（如果呼叫失败）

使用＆＃34;包含＆＃34;这实际上是不可能的。 DIV？我意识到，当我点击某个字段时，该事件将在该字段本身上，然后它会冒泡到容器中...我是否错误地使用它？

我不太确定你想要制作什么但是我为你制作了这个，请检查这是否是你想要的。单击按钮打开模态，将出现该框，其他内容将被模糊。

以下是代码：

＆＃13;

// 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;
}

<div id="blurit">

  <!-- Modal content -->
  <div class="modal-content">

    <p>Some text in the Modal..</p>
  </div>

</div>
