当我将鼠标悬停在HTML表格上时，更改单元格的颜色

问题描述：

我已经浏览了所有发布的答案，但我似乎无法让此代码正常工作。当我将鼠标悬停在单个单元格上时，我试图让单个单元格改变颜色，但我无法使用我们正在使用的服务访问.css。我*放弃一个HTML代码框，可以将我的代码粘贴到特定于我正在更改的元素中，但不是整个.css文件...只是该元素。

I have looked through all the answers posted but I cant seem to get this code to work correctly. I am trying to get the individual cell to change color when I hover over it, but I don't have access to the .css with the service we are using. I am being forced to drop an HTML code box that I can paste my code into specific to the element I am changing, but not the entire .css file...just that element.

这是我的代码。我非常感谢在任何帮助将背景变为＃ff0000以及将文本更改为＃000000时的帮助。

Here is my code. Any help in getting the background to change to #ff0000 and the Text to change to #000000 when I roll over the cell would be greatly appreciated.

（这最终是我的意图为每个单元格添加一个href，但是我一直试图做这一步。> href将（我希望）将选中的单元格添加到购物车中。）

(It is ultimately my intent to add a >a href for each of the cells as well, but I am trying to do this one step at a time. The >a href will (I hope) add the selected cell to a shopping cart.)

预先感谢。

答

在CSS中：

td:hover {
  background-color: #ff0000;
  color: #000000;
}

或者您可以使用JavaScript / jQuery：

Or you can use JavaScript/jQuery:

$(document).ready(function() {
  $("td").hover(
    function() {
      $(this).css('background-color', '#ff0000');
      $(this).css('color', '#000000');
    }, 
    function() {
      $(this).css('background-color', 'none');
      $(this).css('color', 'black'); // or whatever your original color was
    }
  );
});
