Here is my HTML and I would like to remove the function show() when mouse over.

<div id="myDiv" onmouseover="show()">Mouse over me</div>

I cannot remove the onmouseover event using .off() in JQuery

function show() {
   $("#myDiv").off("onmouseover");
 }

But I can remove the attribute using removeAttr()

      function show() {
        $("#myDiv").removeAttr("onmouseover");
      }

I am confused that why .off() doesn't work as expected.
