如何使用 jQuery 更改 mouseenter 和 mouseleave 段落的字体样式?

jQuery 是强大的 JavaScript 库之一,它具有许多强大的方法,可以使用选择器更简单地操作 DOM。

在本文中,让我们看看如何使用 jQuery 在鼠标进入和鼠标离开时更改段落的字体粗细和颜色的不同方法。

方法:使用 jQuery 我们可以在 DOM 事件期间添加许多功能。我们可以使用 jQuery 添加 CSS 动画,如隐藏、显示和许多其他效果。

我们可以添加含有使用addClass()方法MouseEnter事件的CSS类和删除使用removeClass() 在 mouseleave 事件上通过选择p标签选择器。



方法 1:在 mouseenter 和 mouseleave 事件上添加单独的函数。

句法:

$('selector').eventname(function())

        When compared with C++, Java codes are          generally more maintainable because Java          does not allow many things which may          lead bad/inefficient programming if used         incorrectly. For example, non-primitives          are always references in Java. So we          cannot pass large objects(like we can do          in C++) to functions, we always pass         references in Java. One more example,          since there are no pointers, bad memory          access is also not possible.     

       

        Python is a high-level, general-purpose          and a very popular programming language.         Python programming language (latest          Python 3) is being used in web development,         Machine Learning applications, along with          all cutting edge technology in Software          Industry. Python Programming Language is          very well suited for Beginners, also for          experienced programmers with other          programming languages like C++ and Java.
