Longpress / longclick event support / plugin in jQuery

Question

I\'m working on a website which requires mouseover menu\'s. I would not recommend mouseover menu\'s from an accessibility point of view, but it\'s pretty easy to implement using

Something you could do is use delayed checks with setTimeout during the various mouse events. Incorporating jQuery's $.data() to store the timeout across events (on each element) should help you accomplish it all. Here's an example:

HTML:

<ul id="menu">
    <li><a href="#" onclick="return false;" class="test"></a></li>
    <li><a href="#" onclick="return false;" class="test"></a></li>
</ul>

JS:

var mousepress_time = 1000;  // Maybe hardcode this value in setTimeout
var orig_message = "Click Here";  // Remove this line
var held_message = "Down";  // Remove this line

$(document).ready(function () {
    $(".test")
        .html(orig_message)  // Remove this line
        .on("mousedown", function () {
            console.log("#########mousedown");  // Remove this line
            var $this = $(this);
            $(this).data("checkdown", setTimeout(function () {
                // Add your code to run
                $this.html(held_message);  // Remove this line
            }, mousepress_time));
        }).on("mouseup", function () {
            clearTimeout($(this).data("checkdown"));
            console.log("#######mouseup");  // Remove this line
            $(this).html(orig_message);  // Remove this line
        }).on("mouseout", function () {
            clearTimeout($(this).data("checkdown"));
            console.log("#######mouseout");  // Remove this line
            $(this).html(orig_message);  // Remove this line
        });
});

There's a lot more to do with this, since you're also incorporating hovering, but for the most part, I think this does what you want.

It could easily be converted to a plugin if necessary, otherwise I think it could work fine alone. I hope this helps though!

It turns out that you can just use the existing longclick plugin for jQuery 1.4 with jQuery 1.8.

$("#area").mousedown(function(){
    $("#result").html("Waiting for it...");
});
$("#area").longclick(500, function(){
    $("#result").html("You longclicked. Nice!");
});
$("#area").click(function(){
    $("#result").html("You clicked. Bummer.");
});

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
<script src="http://rawgit.com/pisi/Longclick/master/jquery.longclick-min.js"></script>
    
<p id="area">Click me!</p>
<p id="result">You didn't click yet.</p>

You could time it.

function onImageMouseDown(e){
    var d = new Date();
    md_time = d.getTime(); // Milliseconds since 1 Apr 1970
}

function onImageMouseUp(e){
    var d = new Date();
    var long_click = (d.getTime()-md_time)>1000;
    if (long_click){
        // Click lasted longer than 1s (1000ms)
    }else{
        // Click lasted less than 1s
    }
    md_time = 0;
}
