CRM 2013 Use JavaScript on Main.aspx at list level

CRM 2013 Entity forms have the ability to inject the javascript for specific events for specific Elements and stuff like that using In built form load capabilities. I mean we can load the JS file  on form load events for Entity Forms.

Does Main.aspx page where we have Account records list or Contact record list or Lead record list, has any capability to inject the JavaScript?? may be supported or unsupported way?? 

I mean How can I load the JS file on Main.ASPX form load events??

Please assist.
