Handle blur event of parent element fired by focus on child element and by clicking outside of child

Question

I have a "parent div" containing a child box input type=number. When user clicks outside of input box I use blur or focusout event of parent div to use input values at some other place.

I also need to use $('inputbox').trigger('focus') at some place, which fires "parent div"'s blur event unwantedly and runs code on that event.

Please give a solution to stop this parent blur event on child's focus OR give a way to find whether focus is made by trigger('focus') on child element or by user clicking outside of parent div.

I need to fire parent Blur only when user clicks outside of it & not when focus is triggered through code.

Solution 1

with jquery you can make custom events very easily , something like:

$('inputbox').trigger('special-focus');

then you can wait for this event just like any other event:

$('div').on('special-focus' , function(){ ... } );

this will prevent your events from interfering with the built in ones.

I guess if you don't want to use that suggestion then do this in your click handler or your focus handler of the child

 .on('focus' , function(e){
    e.stopPropagation();
    e.preventDefault();
   /// the rest of your code ...
 });

this will stop the propagation of events to parent elements

Solution 2

This worked perfect for me:

if (e.relatedTarget === null) ...

Solution 3

What worked for me was checking the relatedTarget property of the eventObject object in the handler function.

$("#parentDiv").focusout(function (eventObject) {
    if (eventObject.relatedTarget.id === "childInputId")
        /// childInput is getting focus
    else
        /// childInput is not getting focus
});

edited answer , added another solution that will work for you

[Scott Selby]

you can attach to the click event , you might half to play with where to catch the event .

If you're not going to select my answer as the correct answer , then you may want to consider provider a complete answer of what you did to get this code working . Someone else visiting this page would not unserstand just throwing in a custom event there and not showing how it was triggered

[Umesh K.]

.on('focus' , function(e){ e.stopPropagation(); etc will not work here as parent blur fires first.. also working code contains on and off of blur event that's why I didn't mark your answer corrent mate but still it was useful to suggest custom events by you.Had I marked this correct ,developer would keep on trying e.stopPropagation(); which does not work here.

I got that , that is fine , I just meant to write a complete answer ,and I wasn't telling you you had to either , I'm not the Stackoverflow boss, I was just saying you should consider. By complete I didn't mean mine was correct I just meant to fill in the parts you left out

[Umesh K.]

okay mate, also your answer gave a strong direction to work on. appreciable.
