Question

我希望能够在模式的复选框中保留用户决定的数据，并使用模式的复选框决定发送它而不离开页面或重新加载。

如果用户决定选中模式中的复选框，当按继续时，如何保留该数据，然后等待提交按钮发送所有复选框的值。

var btn = document.getElementById("myBtn");

// 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";
  }
}

/* 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 {
  position: relative;
  background-color: #fefefe;
  margin: auto;
  padding: 0;
  border: 1px solid #888;
  width: 80%;
  box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);

/* The Close Button */

.close {
  color: white;
  float: right;
  font-size: 28px;
  font-weight: bold;
}
.close:hover,
.close:focus {
  color: #000;

  padding: 2px 16px;
}
.modal-footer {
  padding: 2px 16px;
  background-color: #5cb85c;

不要将模态视为与您的页面分开的实体。模态在页面上只是一个普通的div ，但它位于其他内容的中心位置。但它只是一个普通的div，你可以随时读取模态中元素的值，即使它是不可见的。

模态复选框中的值仍然可用，就像它们位于不同的div中一样。如果您的表单在模态中，那么它们仍然是表单的一部分。如果表单在模态之外，那么您希望随时使用javascript / jQuery 来读取该复选框并影响您的表单。

下面是一个示例，其中表单位于模态之外，当模式关闭时，javascript会更新表单字段的值。
