谢谢。

jquery中的
hover
方法通常需要两个处理程序，一个用于
mouseIn
，另一个用于
mouseOut
。我对您的代码进行了一些修改，以包含这两个处理程序

对HTML的更改：

  <td class="nav-blurb">

对JS的更改：

$( document ).ready( function() {

        function() {
            $( ".nav-p-blurb" ).text("This is a home page blurb and it will talk about the home page like the other blurbs will talk about their specific pages and hopefully appear correctly");

});
我不会为每个菜单按钮添加单独的函数，而是为每个href添加一个数据字段，其中包含要显示的文本，我将以下一种方式运行该函数：

  <title>website</title>
  <link rel="stylesheet" href="styles/navbar.css">
  <link rel="stylesheet" href="styles/index.css">

 <table class="nav-table">
 <tr>
  <td width="600" class="nav-img">

   <img  class="nav-img" src="img/header-img.png" width="600" height="200">

  </td>

  <td width="100" class="nav-links-td">

  <div class="nav-links">

      <br>
   <div class="nav-b-div"><a href="#" class="nav-buttons about">About</a></div>
      <br>
   <div class="nav-b-div"><a href="#" class="nav-buttons projects">Projects</a></div>

  </tr>
 </table>

$(".nav-buttons").hover(function () {

$(".nav-p-blurb").text($(this).attr("data-mytext"));

上次更新 根据用户的要求，他希望文本也像菜单一样左右滑动。请看最新的小提琴。要实现类似效果，您需要一个div，该div隐藏内容，而不是设置动画宽度

是的，它可以，但你有3个工作的例子，从我和一些其他人的解释以及，所以你至少应该试着找出自己的。这里没有人是为别人免费编写代码的，这是关于帮助和支持的，而不是关于代替你完成工作的。话虽如此，请参见最后一个示例

你能创建一个简单的JSFIDLE来演示这个问题吗？谢谢你的建议，它工作得非常好-但是
.nav-p-blurb
中的文本不能动画化吗？你想添加什么动画？这太棒了！这一点令人惊讶，但有没有一种方法可以反转动画方向？悬停时，如果链接完成其动画，然后模糊动画开始，并沿与链接动画相同的方向继续，则该项目将是完美的。如果你能让它工作起来，这将是非常棒的。谢谢你到目前为止的帮助，真是太棒了！令人惊叹的！谢谢，下次我会采纳你的建议：）太棒了，我没意识到我需要做的只是添加一个默认状态。谢谢你的帮助！在开始淡入效果之前，我是否可以等待0.2秒？如果可能，我可以等待0.2秒，然后让文本以滑动方式显示吗？比如链接如何突出显示？$（“.nav-p-blurb”）.delay（200）。fadeIn（1000）；
