[jQuery] use of this in jQuery selectors


Hi All
Can someone clarify the use of the JavaScript keyword
this
in a jQuery context?
I find it strange that the following code doesn't work
$(this + '.requiredField')
but this does
$(this.id + '.requiredField')
even when the object calling the code does not have an id attribute!
Is there a way to mix the very handy
this
keyword with the sensational ability of jQuery to get an array of
objects with blah class name ?
