Is it possible to write onFocus/lostFocus handler for a DIV using JS or jQuery?

Question

I have a div and when the user clicks the div a function should be called. And when the user clicks something else (anything other than this div) another function should be called.

So basically i need to have onFocus() and lostFocus() function calls associated with this DIV. Is it available in JavaScript or even in jQuery?

Thanks.

You need to add tabindex attribute to div :

$("#mydiv").focusin(function() {
  $("#mydiv").css("background", "red");
});
$("#mydiv").focusout(function() {
  $("#mydiv").css("background", "white");
});

#mydiv {
  width: 50px;
  height: 50px;
  border: 1px solid red;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="mydiv" tabindex="100"></div>
<div id="anotherdiv"></div>

Focus do not work on DIV : http://api.jquery.com/focus/

ALso good read: jquery : focus to div is not working

If you want to focus a div or anything normally can't be focused, set the tag's tabindex to -1 first.
eg: $("div#header").attr("tabindex",-1).focus();
