mouseupevent happens when the mouse button is released while the cursor is still over the element. 
Usage of .mouseup() Method
The jQuery .mouseup() sets an event handler, running a function when the mouseup event occurs. The method can invoke the event as well.
Try clicking on the text in the example. If you release the button while still on the text, a message will appear beneath it:

$("div").mouseup(function() {
   $(this).after("<p>Hey there!</p>");
});
Use this syntax to trigger the mouseup event:
$("selector").mouseup();
Add the function parameter to attach the event handler:
$("selector").mouseup(function);
Tip: to make jQuery get mouse position, use event.pageX and event.pageY.
