若要更改背景颜色,请使用mouseenter事件。放置鼠标光标时背景色发生变化:
mouseenter: function(){ $(this).css("background-color", "gray"); }
鼠标光标放在以下元素上:
<p class="my">Click and move the mouse pointer to change the background color.</p>
您可以尝试运行以下代码,以了解如何为鼠标悬停时的背景色变化设置动画:
<!DOCTYPE html> <html> <head> <script src="https://cdn.staticfile.org/jquery/3.2.1/jquery.min.js"></script> <script> $(document).ready(function(){ $("body").on({ mouseenter: function(){ $(this).css("background-color", "gray"); }, mouseleave: function(){ $(this).css("background-color", "red"); }, }); }); </script> </head> <body> <p class="my">Click and move the mouse pointer to change the background color.</p> </body> </html>
