【Yii框架】YII分页组件
No. 1
效果：
代码：
class LinkPage extends CLinkPager
{
public function run()
{
$pageLinks = $this->createPagePreAndNext();
$topPage = CHtml::tag("div", array("class"=>"topPage"), $pageLinks);
$form = $this->createForm();
$toPage = CHtml::tag("div", array("class"=>"toPage"), $form);
echo CHtml::tag("div", array("class"=>"page"), $topPage.$toPage);
}
/**
* @desc 创建向前和向后的链接
* @return string a标签和span标签的html代码
*/
private function createPagePreAndNext()
{
$links = "";
if ($this->pages->getCurrentPage()>=1) {
$links .= CHtml::link($this->prevPageLabel, $this->createPageUrl($this->pages->getCurrentPage()-1), array("class"=>"prePage"));
} elseif (0 == $this->pages->getCurrentPage()) {

}
$links .= CHtml::tag("span", array("class"=>"pageNum"), $this->pages->getCurrentPage()+1 . "/" . ($this->pages->getPageCount()?$this->pages->getPageCount():1));

效果：
注：这里总数不一定是八页，可以指定显示的连接页数，这里指定的是八页。
代码：
class ListLinkPage extends CLinkPager
{
public $listNum = 8;
public $pageArr = array();
public $startPage;
public $endPage;
public function run()
{
$this->listArr();
$code = $this->makeListHtml();
$code .= $this->makePrevAndNext();
echo $code;
}
public function getListNum()
{
return $this->listNum;
}
public function setListNum($num)
{
is_numeric($num) && $this->listNum = intval($num);
}
/**
* 计算链接的起始和结束位置
*/
private function listArr()
{
//计算数字下标，当前页标之前需要显示多少个下标 和 当前页标之后需要显示多少个下标
$back = ceil(($this->listNum - 1)/2);
$pageNow = $this->pages->getCurrentPage() + 1;
$count = $this->pages->getPageCount();
$this->endPage = ($pageNow+$back>$count)?$count:$pageNow+$back;
$this->startPage = ($pageNow+$back>$count)?(($count-$this->listNum)<1?1:($count-$this->listNum+1)):(($pageNow-$back+(($this->listNum%2)^1))<1?1:($pageNow-$back+(($this->listNum%2)^1)));
($this->endPage-$this->startPage < $this->listNum - 1) && $this->endPage = $this->listNum - $this->startPage + 1;
}
/**
* 生成上一页和下一页的html代码
*/
private function makePrevAndNext()
{
$htmlcode = "";
(($this->pages->getCurrentPage()<=0) && ($htmlcode .= CHtml::tag("span", array(), $this->prevPageLabel))) || ($htmlcode .= CHtml::link($this->prevPageLabel, "", array()));
(($this->pages->getCurrentPage()+1 < $this->pages->getPageCount()) && ($htmlcode .= CHtml::link($this->nextPageLabel, "", array()))) || ($htmlcode .= CHtml::tag("span", array(), $this->nextPageLabel));
return $htmlcode;
}
/**
* 生成列表链接的html代码
* @return string
*/
private function makeListHtml()
{
$htmlCode = "";
for($step=$this->startPage;$step<=$this->endPage;$step++){
(($step == $this->pages->getCurrentPage()+1) && ($htmlCode .= CHtml::tag("strong", array(), $step))) || ($htmlCode .= CHtml::link($step, "", array()));
}
return $htmlCode;
}
}注：这两个里面的 $this->pages 都是Yii 中 CPagination类的实例。
