Is there a DOM event that fires when an HTML select element is closed?

I'm looking for a DOM event that I can listen to with JavaScript for when a select element that has been opened (but no options changed) is then closed by clicking off the select element, somewhere (anywhere) else on the page.

It's not the blur event of the select, because the select retains focus. Likewise, it's not the focus event of some other element or the document, or a mousedown or click on the window, document or body.

It's not the change event of the select, since no option within the select has been changed.

I'm not concerned about legacy Internet Explorers - just something to work in standards compliant modern browsers. Proprietary hacks could be worth knowing though.

I've created a JSFiddle to demonstrate the problem:

  1. Click on the selectbox in the "Result" panel
  2. Click on the text marked "HERE" (or anywhere else) with a single click and see if any event is added to the log. There isn't an event in the latest Chrome or Firefox.

So the question is: What JavaScript could be added, to get an event logged when clicking off the selectbox?

(I've asked a similar, but different question here:
JavaScript on iOS: opening an HTML select element)



When you have more then 1 dropdown:

        $("select").each(function () {
        var initDropdown = $(this);"open", false);
        console.log( + "   closed");

        initDropdown.on("blur", function () {
            var blurDdopdown = $(this);
  "open", false);
            console.log( + "   closed");

    $("select").bind("click", function () {
        var clickedDropdown = $(this);

        if ('open') == false) {
  'open', true);
            console.log( + "   open");
        } else {
  'open', false);
            console.log( + "   closed");

I got the following events by following the directions on your JSFiddle to the letter:

BODY, mousedown, STRONG
#document, mousedown, STRONG
window, mousedown, STRONG
#document, click, STRONG
window, click, STRONG

These are all events that were triggered when I clicked "HERE" after the select menu was already in focus and expanded. This was in the latest version of Chrome.

Shouldn't any one of these suffice for your purposes?

Edit: If you want to make sure it's your Select element that's losing focus, set a global Javascript variable, 'selectFocused', and set it to False. Set it to True when your Select menu receives focus, and set it to False when any of the above events occurs. 'selectFocused' can now be used anywhere in your code to detect whether or not your Select element currently has focus, and when it changes values, you know your Select element has been selected or unselected.


My first instinct is a little roundabout in its way to achieve this, it would be to use the code you normally use for closing a (custom) dropdown menu on press outside:

function clickInBody(){

function clickInBodyStop(event){

Then on your body tag you add onClick="clickInBody()" and on your select item you add onClick="clickInBodyStop(event)". This should call the event every time you click on the page, but if you click on the select tag it will stop the propagation and not call functionToCallOnBlur()


precondition: using jQuery! This will probably only solve part of your problem, but if you are looking for an event to fire when you click off an element, you can use an overlay div.

When the user clicks on the select box:

$('#mySelectBox').click(function () {
    var myOverlayDiv = $('<div id="overlayDiv" class="overlayDiv"></div>')
    .click(function () {
        // call your "select lost focus" function here
        // which should include $('#overlayDiv').remove() somewhere!

Style for the overlay div:

.overlayDiv {

You need to make sure that your select box menu is a higher Z-index so when the user clicks on the menu they get the menu and not the overlay div :)


If we consider clicking outside the selection box can be a signal of the ending selection event.

The following jQuery can do this. Here is code in fiddle

$(function () {
    let flag = 0;

    $("#selectId").click(function (e) {
        if (flag === 0) {
            flag = 1;
            $(document).one("click", function () {
                flag = 0;
                alert("select end");

Html code:

<select multiple id="selectId">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>


Unfortunately there's no standard event for knowing when a select box is closed or open, so your code is going to be pretty hairy with accommodations for different browsers. That said, I think it can be done, and I've gotten something working for you in Firefox using the mouseup event:

In Firefox (and I'm assuming Chrome), you're going to need to track the state of that select pretty carefully. When an escape key is pressed or blur event occurs, you need to update the state to identify it as closed. I haven't implemented that in my demo, and you can see what happens if you hit escape instead of clicking off the select.

Things were easier in Safari, where a mousedown event on the select signifies opening the select, and any close of the select is signified by a click event.

If you find a browser where none of these events fire, you can try one additional trick. Because form widgets like select and textarea are often rendered by the OS and not inside the browser it's possible that you could interact with them and certain messages might not get down to the browser's event handler. If you were to position a transparent textarea covering the screen at a lower z-index when the select box is open, you might be able to use it to track that close click. It may be able to capture events that a browser DOM element may miss.

Update: Chrome sees a mousedown on the select when it opens and a mouseup on the document when the page is clicked with a select open. Here's a version that works with Chrome:

Again, you'll need to do some browser detection to handle the right behavior in each one. One catch with Chrome, in particular, is that no event is fired when you click on the select a second time to close it. You can detect the page click, however.

Quick Summary:

Chrome/Safari: select.mousedown on open, document.mouseup on close
Firefox: on open, document.mouseup on close
IE8/IE7: on open, document.mouseup on close

There are an awful lot of edge cases for other events that will signify a close (escape keypress, blur, etc.), but these are the minimum to handle the scenario where a user clicks the select box and then clicks off into the document area.

Hope this helps!
