答
放入JS文件位于js文件夹的某个位置，在XML布局中，您可以将其包含在：
Put the JS file somewhere into the "js" folder, and in the XML layout you can include it with:
<reference name="head">
<action method="addJs"><script>folder/file.js</script></action>
</reference>
希望有所帮助。
编辑：您也可以在您的区块中执行此操作：
You can also do it in your block:
protected function _prepareLayout()
{
$this->getLayout()->getBlock('head')->addJs('path/from/js/folder/to/your/file.js');
return parent::_prepareLayout();
}
