Yii中render和renderPartial的区别,yiirenderpartial

以下由我们在信易网络公司开发项目的时候终结出的一些经验
在进行页面输出渲染的时候。

1.render 输出父模板的内容,将渲染的内容,嵌入父模板。|
2.renderPartial 则不输出父模板的内容。只对本次渲染的局部内容,进行输出。

同时还有个重要的区别:

render 函数内部默认执行processOutput($output)函数, 会将把组件,比如 CTreeView 里面注册到 CClientScript 里面的
需要的脚本进行渲染输出。

而renderPartial() 默认不自动渲染输出客户端脚本,需要进行参数的指定,才会输出:
renderPartial($view,$data=null,$return=false,$processOutput=false)
指定processOutput 为 true 即可。

比如要局部输出 CTreeView ,用renderPartial 进行渲染,如果按照默认processOutput=false 则输出内容,不含有客户端脚本
输出内容则为 正常的 ul 列表。没有树形的折叠效果。 主动设定 processOutput=true 后,CTreeView 所需的,所有客户端脚本就会被正常输出在列表的前面。

下面介绍下要用到的几个相关的函数:

render,renderPartial 不再介绍
processOutput()

<&#63;php
publicfunction render($view,$data=null,$return=false)
{
  if($this->beforeRender($view))
  {
    $output=$this->renderPartial($view,$data,true);
    if(($layoutFile=$this->getLayoutFile($this->layout))!==false)
      $output=$this->renderFile($layoutFile,array('content'=>$output),true);
    $this->afterRender($view,$output);
    $output=$this->processOutput($output);
    if($return)
      return $output;
    else
      echo $output;
  }
}
publicfunction renderPartial($view,$data=null,$return=false,$processOutput=false)
{
  if(($viewFile=$this->getViewFile($view))!==false)
  {
    $output=$this->renderFile($viewFile,$data,true);
    if($processOutput)
      $output=$this->processOutput($output);
    if($return)
      return $output;
    else
      echo $output;
  }
  else
    thrownewCException(Yii::t('yii','{controller} cannot find the requested view "{view}".',
      array('{controller}'=>get_class($this),'{view}'=>$view)));
}
publicfunction processOutput($output)
{
  Yii::app()->getClientScript()->render($output);
  // if using page caching, we should delay dynamic output replacement
  if($this->_dynamicOutput!==null&& $this->isCachingStackEmpty())
  {
    $output=$this->processDynamicOutput($output);
    $this->_dynamicOutput=null;
  }
  if($this->_pageStates===null)
    $this->_pageStates=$this->loadPageStates();
  if(!empty($this->_pageStates))
    $this->savePageStates($this->_pageStates,$output);
  return $output;
}

以上在实际操作中还是比较有用的,比如你不想用大组建,可以直接将变量输到模板,也可以将多个变量组成数组输到模版里面去.

yii框架layouts里mainphp想再引用一个页面该怎写?render好像不行

require就行了啊,如果非要用render()的话用renderPartial()
 

yii 通过redirect()或render 怎跳转到父页面

例如:
1. Yii::app()->user->returnUrl = Yii::app()->getBaseUrl()."/step/show/id/1";
$this->redirect(Yii::app()->user->returnUrl);
2. $this->redirect(array('step/show','id'=>1));
3. $this->render('index',array('post'=>$questions));
4. $this->renderPartial('field_show',array('field'=>$field,'key'=>++$key,));
