Question

我想用模态弹出窗口做一些事情，但我对模态弹出窗口及其代码不太了解。

所以我想用主网页上的文本框更改模态弹出窗口的内部。我在文本框中写了一些内容然后当我点击按钮时，应该更改模态弹出窗口内部。此外，当我向文本框写入内容时，按钮的模式弹出窗口内的文本框也应该更改主页面的输入段落。

我试过这样的事情：

HTML

<h2>Modal Example</h2>

<!-- Trigger/Open The Modal -->
<input type="text" id="to" value="Something">
<br>
<button id="myBtn" onclick="myFunction()">Open Modal</button>

<!-- The Modal -->
<div id="myModal" class="modal">

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

        <br>
        <span class="close">&times;</span>
        <p id="demo">.</p>
    </div>

</div>

CSS

/* 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;
}

JS

function myFunction(){
 var x = document.getElementById("to").innerHTML;
 document.getElementById("demo").innerHTML=x;
 }
// 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";
}

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
    modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
    if (event.target == modal) {
        modal.style.display = "none";
    }
}

您是否需要这种实施方式请运行示例以查看它的实际效果。

＆＃13;

// Get the modal
var modal = document.getElementById('myModal');

//Modal open function
function openModal() {
  modal.style.display = "block";
  document.getElementById('demo').innerHTML = document.getElementById('to').value;
}

//Modal text update function
function udpateText() {
  modal.style.display = "none";
  document.getElementById('paragraph').innerHTML = document.getElementById('from').value;
}

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
  modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
  if (event.target == modal) {
    modal.style.display = "none";
  }
}

/* The Modal (background) */

.modal {
  display: none;
  /* Hidden by default */
  position: fixed;
  /* Stay in place */
  z-index: 1;
  /* Sit on top */

  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%;

  </div>

</div>

Answer 2

这是一个使用jquery ui modal的实现。

此行将文本输入放入模态内容中。 $('#content').text($('#myinput').val());
