javascript - Prototype Selection Help -

Hey guys, I'm trying to make a little extra for any web app using. Right now I am trying to check all the checkboxes on the page, in which the class .checkbox ( is required to select / select the case ). Checkboxes are the descendants of the class .someClass , it's just that there are many divs that are classes.

  & lt ;! - Check this box - & gt; & Lt; Div class = "some class" & gt; [...] & lt; Input type = "checkbox" class = "check box" /> gt; & Lt; / Div & gt; & Lt ;! - But this one is not - & gt; & Lt; Div class = "some class other class lolvat" & gt; [...] & lt; Input type = "checkbox" class = "check box" /> gt; & Lt; / Div & gt;  

Remember, checkboxes are not direct children, but lineage

Thank you, I appreciate any help.
