Add a javascript file in Magento 1.9

Question

I'm discovering magento since 1 week. But i have a problem now. I need to include a javascript file in my admin panel to sort a list according to another. I'm using magento 1.9 and i really don't find any tutorial to do this.

Please can someone explain me clearly how to do this because i'm really stuck at this point.

Answer 1

First you have to choose a relevant layout(.xml) file based on the grid/page you want to include your javascript in.

Then in that layout you need to add the below code in the relevant section:

<layout>
  <adminhtml_{relevant_layout_handle}>
    <reference name="head">
            <action method="addJs"><script>my_extension/adminhack.js</script></action>
            <action method="addJs"><script>prototype/prototype.js</script></action>         
        </reference>
  </adminhtml_{relevant_layout_handle}>
</layout>

Then you need to clear Magento caches and check if your file is loaded or not.

Hope this works for you
