（3）选择元素——（15）总结（Summary）

With the techniques that we have covered in this chapter, we should now be able to locate sets of elements on the page in a variety of ways. In particular, we learned how to style top-level and sub-level items in a nested list by using basic CSS selectors, apply different styles to different types of links by using attribute selectors, add rudimentary striping to a table by using either the custom jQuery selectors :oddand :evenor the advanced CSS selector :nth-child(), and highlight text within certain table cells by chainingjQuery methods.

 

拥有了本章我们讲过的知识后，我们现在可以通过很多方法定位网页上的一串元素。特别的，我们学会了使用基础的css选择器在嵌套的结构中去定位顶部和子级的元素，学会了使用属性选择器为不同类型的链接加上不同的样式，使用定制选择器:odd和:even或者高级选择器:nth-child()给一个表加上交替的条纹，使用链状jquery方法为特定的表格块高亮文本。

 

So far, we have been using the $(document).ready()method to add a class to a matched set of elements. In the next chapter, we'll explore ways in which to add a class in response to a variety of user-initiated events.

到目前为止，我们已经使用了$(document).ready()方法为一些匹配的元素集合添加方法。在下一章节，我们将学习如何相应用户的起始事件来添加一个类。
