ZendFramework - 如何从控制器添加 -> HeadScript()? [英] ZendFramework - How to add ->HeadScript() from Controllers?

问题描述

我有一个案例，我需要将控制器中的 Javascript 添加到已经有 HeadScript() 的布局中；

I have a case where i need to add the Javascript from controller to the Layout where it has already HeadScript();

如何从控制器做到这一点?

How to do that from controller?

例如:$this->view->HeadScript()->appendScript();

这是控制器:两者都不适用.

This is controller: Both does not apply.

class RouterController extends Zend_Controller_Action
{
  public function init()
  {
    $this->view->HeadScript()->appendFile('/js/test.js')->setIndent(8);
    $this->view->HeadScript( Zend_View_Helper_HeadScript::FILE, '/js/test.js' );
  }
}

这是视图文件:index.phtml

This is the view file: index.phtml

<?//$this->HeadScript()->appendFile('/js/test.js')->setIndent(8);?>

如果我在视图中取消注释它可以工作但在控制器中不起作用.我想现在如何从控制器应用它?

If i uncomment in view it works but not in Controller. I want to apply this from controller how now?

推荐答案

我从控制器中的 preDispatch 方法得到了这个，记住你必须在传递标题之前传递布局更改.

I got this to work from the preDispatch method in a controller, remember you have to pass layout changes before headers are passed.

public function preDispatch() {
        parent::preDispatch();
        $layout = new Zend_Layout();

        $layout->getView()->headScript()->appendScript('/javascript/form.js', 'text/javascript');
    }

您仍然必须在布局中使用 headScript 占位符.

you still have to have the headScript placeholder in your layout.
