Jquery: if mouseleave = true then DO THIS

Simple question, how would I accomplish this functionality in Jquery: Test whether the mouse is hovering over .myBox

    if ($(".myBox").mouseleave = true) {
        DO SOMETHING
    }开发者_如何转开发 else {something else}

OR

    if ($(".myBox").mouseover = false) {
        DO SOMETHING
    } else {Something else}

NOTE: im looking for an IF statement

jQuery provides the is method for checking conditions with regard to a jQuery object. In your case you can check for the :hover CSS pseudo class:

$('.myBox').is(':hover') === true

Havre a look at this demo, try clicking the button (which will alert true) and the tabbing to and hitting enter on the button (without the mouse, it will return false).

Take a look at jQuery Mouse Over

$(".my_box").mouseover(function(){
    // Mouse over...
});

$(".my_box").mouseout(function(){
    // Mouse left...
});

Here is an example, adding a border to an image when hovering over it, and removing it after x amount of time if its not been re-hovered: See it working here

var hover_off = false;
var hover_count = 1000;

$(".my_box").mouseover(function() {
    hover_off = false;
    $(this).addClass('hovering');
});

$(".my_box").mouseout(function() {
    hover_off = true;
    setTimeout(myMouseOut, hover_count);
});

function myMouseOut() {
    if (hover_off) {
        $(".my_box").removeClass('hovering');
    }
}

That's right, $('.myBox').is(':hover') used with jQuery 1.5.1 throws the error, but in my tests only in Opera Browser (11.01): Uncaught exception: Syntax error, unrecognized expression: hover

A workaround is using a negated expression: $('.myBox').is('not(:hover)') That worked fine while my tests in Opera 11, FF4, IE7, Chrome 5.

Use .hover() http://api.jquery.com/hover/

---

$(".myBox").hover(
           function(){
               //DO SOMETHING ON MOUSE ENTER
           },
           function(){
               //DO SOMETHING ON MOUSE LEAVE
           }
 });

---

This did the trick for me:

var hover = false;
$('.someClass').each(function(i,e){
    hover = !hover ? $(e).is(':hover') : true;
});

if (hover)
    // do something
else
    // do something else

---

use this: http://plugins.jquery.com/project/enterleave-events

$('.myBox').bind('enter leave',function() {
  // do something, use $(this) to get the object
});

---

Act on the mouseenter and mouseleave events.

Or use the hover which can handle both of them..

$('.myBox').hover(
   function(e){
     //do the mouseenter things here...
   },
   function(e){
     //do the mouseleave things here...
   }
);
