[程式] jQuery Tips

• (Selector) 選取Nested Item
  ex.
  欲選取下方程式碼中 class 為 next_page 的 href
  
  <div class="load_more">
      <div class="pagination">
          <em class="current">1</em>
          <a class="next_page" rel="next" href="/category_posts/books?page=2">2</a>
      </div>
  </div>
  => $(".load_more .pagination .next_page").attr("href")
• (Selector) 利用 ".text()" 選取 <...>和</...> 間的文字
  ex.
  欲選取<a id="myID">This is a link</a>中的"This is a link"
  => $.("#myID").text()
