I\'m a beginner in JQuery,
How can I get the control as a javascript object from a JQuery object
var _object = $(this). ??
In your case, simply use this.
this
$(this)[0] == this if this is a DOM element. If it's something else, e.g. a selector, $(this)[0] is the way to go.
$(this)[0] == this
$(this)[0]
