如何在悬停3秒后开火

Question

I have a div and I want to fire an event only after user continuous hovers his mouse for 3 sec. My code doesn't work well because it fires right after hover and doesn't "wait".

Code:

$(".inner_pic").mouseenter(function () {
    setTimeout(function () {
        alert('testing');
    }, 3000);
}).mouseleave(function () {
    alert('finish');
});  

Answer 1

You need to store timeout id somewhere and clear it on mouseout. It's convenient to use data property to save this id:

 $(".inner_pic").mouseenter(function () { $(this).data('timeout', setTimeout(function () { alert('testing'); }, 3000)); }).mouseleave(function () { clearTimeout($(this).data('timeout')); alert('finish'); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="inner_pic">PICTURE</div> 

Answer 2

You can achieve this by delay option:

Working demo

$('#elem').popover({
    trigger: "hover",
    delay: {show : 3000, hide : 0} });

Answer 3

Checkout the below code

 var myVar; $( "div#container" ) .mouseover(function() { myVar = setTimeout(function(){ alert("Hello"); }, 3000); }) .mouseout(function() { clearTimeout(myVar); }); 

 div { background: red; margin: 20px; height: 100px; width: 100px; display:block; cursor: pointer; } div:hover { background: yellow; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="container"></div> 

Answer 4

Try This Code:

<div id='a' style="border:2px solid black" >
    <h3>Hove On me</h3>
    For 2000 milliseconds. You will get an alert.
    </br>
    </div>

$(document).ready(function(){
   var delay=2000, setTimeoutConst;
   $('#a').hover(function(){
        setTimeoutConst = setTimeout(function(){
            /* Do Some Stuff*/
           alert('Thank You!');
        }, delay);
   },function(){
        clearTimeout(setTimeoutConst );
   })
})

</script>

Answer 5

 var st; $(".inner_pic").mouseenter(function(e) { var that = this; st = setTimeout(function() { alert('testing'); }, 3000); }).mouseleave(function() { clearTimeout( st ); alert('finish'); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="inner_pic"> <h3>Picture Here - Hover me</h3> </div> 

Answer 6

Assuming you have a div with id of myelement , you can do this:

var divMouseOver;
$('#myelement').mouseover(function() {
  divMouseOver = setTimeout(function() {
     alert("3 seconds!"); //change this to your action
  }, 3000);
});
$('#myelement').mouseout(function() {
  if (divMouseOver) {
    clearTimeout(divMouseOver);
  }
});

BTW, tere's a helpful clarifying question re: using mouseenter and mouseover right here: Jquery mouseenter() vs mouseover() . Consider this when choosing which to use.
