✿学习- 如何添加翻页功能

♪ 学习- 如何添加翻页功能 ♪

写一些,提醒我自己修改了什么,将来要修改时可以参考。
---------------------------------------------------------------
我发现,当文章越写越多时, 用以往的Older Post 或 Newer Post 功能有一点麻烦,因为要一页一页的翻。
后来索性把它改为是有显示页数的,这样随便我要翻第一页也可以,第三页也ok.

怎样添加?很容易,跟着以下步骤就可以了:

去Design -> Add Gadget -> 加 HTML/JavaScript (这时会有小窗口跳出来)

把以下框框内的全部copy 然后 paste 在 content 的地方就可以了。

<style>
.showpageArea {padding: 0 2px;margin-top:10px;margin-bottom:10px;
}
.showpageArea a {border: 1px solid #505050;
color: #000000;font-weight:normal;
padding: 3px 6px !important;
padding: 1px 4px ;margin:0px 4px;
text-decoration: none;
}
.showpageArea a:hover {
font-size:11px;
border: 1px solid #333;
color: #000000;
background-color: #FFFFFF;
}
.showpageNum a {border: 1px solid #505050;

按Save 后,就可以了。
现在回到部落格去看,翻页功能已经取代了旧的Older Post 或 Newer Post 功能。 :)
