如何使用 jQuery 选择具有特定类的 div？

给定一个包含许多带有类的div 元素的 HTML 文档。这里的任务是选择一个具有特定类的 div，它没有另一个类。有两种方法可以解决这个问题。在其中一个中，我们将使用一种方法，而在另一个中，我们将使用 not 选择器。

方法一：首先使用jQuery Selector选择具有特定类的DIV，然后使用:not选择器忽略特定类的元素。

示例：此示例实现了上述方法。

        that doesn't have another class.

        class, that doesn't have another class.
    
 
   
    
    
        This is first Div
    
    

    
        This is second Div
    
    

    
        This is third Div
