Question

我已经建立了一张桌子。部分屏幕截图如下：

小问号会打开一个信息弹出窗口。看起来像这样：

我想使用如下模式弹出窗口：

这看起来好多了。我无法弄清楚如何从表单元格中执行模态代码。它在独立的html文件中工作正常。我只是无法使其在我的表数据单元中工作。我把它放在身体的开始。

它确实将问号放在正确的位置，但是单击问号后没有任何反应。

// Get the modal
var modal = document.getElementById('myModal');

// Get the button that opens the modal
var btn = document.getElementById("myBtn");

btn.onclick = function() {

Answer 1

问题是您不能有多个ID拥有相同的名称。它们必须是唯一的，因为它只会尝试解雇第一个。这是一个工作示例，在其中我还添加了一些HTML以使其成为真正的表格。

// 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";
  }
}

body {
  font-family: Arial, Helvetica, sans-serif;

  padding-left: 0px;

  top: 0;
  width: 50%;

  height: 100%;
  /* Full height */
  overflow: auto;
  /* Enable scroll if needed */

Answer 2

您两次使用ID "myBtn"。修复了以下代码段：

// Get the modal
var modal = document.getElementById('myModal');

// Get the button that opens the modal
var btn = document.getElementById("myBtn");
var tableBtn = document.getElementById("tableBtn");

// 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";
}
tableBtn.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";
  }
}

body {
  font-family: Arial, Helvetica, sans-serif;
}


/* The Modal (background) */

.modal {
  display: none;
  /* Hidden by default */
  position: fixed;
