如何增加表格中模态的大小

Question

我做了一张桌子，我想让不同的单元格都可以点击，然后出现一个模态。当模态在一行中时，我已经可以正常工作了，请参见代码段中的test3。

但是，当我在多行中创建模式时，它不会使整个单元格都可单击，而只是其中一部分。当我将鼠标悬停在其上方时，它只会更改可单击部分的颜色，但是我希望整个单元格都可单击，因此当我将鼠标悬停在其上方时会更改颜色。就像“ test3”一样。

如何更改它以使其覆盖整个单元格？

var btn = document.querySelectorAll("button.modal-button");


var modals = document.querySelectorAll('.modal');

// Get the <span> element that closes the modal
var spans = document.getElementsByClassName("close");

// When the user clicks the button, open the modal
for (var i = 0; i < btn.length; i++) {
  btn[i].onclick = function(e) {
    e.preventDefault();
    modal = document.querySelector(e.target.getAttribute("href"));
    modal.style.display = "block";
  }
}

// When the user clicks on <span> (x), close the modal
for (var i = 0; i < spans.length; i++) {
  spans[i].onclick = function() {
    for (var index in modals) {
      if (typeof modals[index].style !== 'undefined') modals[index].style.display = "none";
    }
  }
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
  if (event.target.classList.contains('modal')) {
    for (var index in modals) {
      if (typeof modals[index].style !== 'undefined') modals[index].style.display = "none";
    }
  }
}

Answer 1

只需更改CSS。

td.modalTD:hover {
background-color: yellow;
}
td.modalTD:hover .block {
background-color: yellow; 
}

当您将鼠标悬停在td上时，td和块的背景颜色都会改变。
