hi

in jquery

what does the "this" mean in $(this).css("background-color","yellow");

and in what context is it used?

thanks

Here, it's the element on which jQuery is acting. So for example if you assign a click event:

$('#myelement').click(function(){
     $(this).css("background-color","yellow");
});

then $(this) would refer to #myelement. This becomes more useful when the selector applies to multiple elements:

$('.myelements').click(function(){
     $(this).css("background-color","yellow");
});

when it will apply to whichever element having class myelements was clicked. Another common usage might be within .each():

$('.myelements').each(function(){
     $(this).css("background-color","yellow");
});

where it would apply to each element having class myelements in turn through the .each iteration.

That might do you for starters - for some more detail Google finds this article.
