html - make the 'this' keyword refer to the calling object (javascript) -


I have read some topics about this, however, I still can not understand it. Just what I want what is giving 'this' statement gives context to the object that is calling the function, while it talks about the window ..

My function looks like this: 

  function bckClr (clr) {var elmnt = this; Elmnt.style.background color = clr; }   
 And I call it like this:  
  & lt; Div & gt; Onmouseover = "bckClr (# ff0000)" & gt; Lorim Advertising Dolter Site Atom ..     
 
 
 Do this like this:  
  & Lt; Div onmouseover = "bckClr (this, '# FF0000')" & gt; Lorim Ipsum Dollar Ast Amit .. & lt; / Div & gt;   
 And then:  
  function bckClr (elmnt, clr) {elmnt.style.backgroundColor = clr; } Update:  Update:

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part.
