Reload Animated Gif cache each jQuery hover

问题

Different to: Restart an animated GIF from JavaScript without reloading the image

I have a simple animated gif icon which plays once (it does not repeat loop)

I have it inside a DIV. When the user mouse the mouse over the DIV I want to play the GIF. When they move out the DIV turns off. When the move back I want them to play the GIF again - can I use a force cache on jQuery:

HTML:

<div class="datebox magicbox_1" id="date_1">
  <img id="magicimage_1" class="magicimg" src="assets/img/dates/gifpicture.gif" alt=""/>
</div>

jQuery:

    $("#date_1").hover(function () {
        $("#magicimage_1").show();
    }, function () {
        $("#magicimage_1").hide();
    });

// thought about these
/*
var myImg = new Image();
myImg.src = "image.gif?rnd=" + Math.random();
img src="filename.gif?rand=<#?=rand(1,1000);?>" alt=""
*/

I updated the old code to show the images reset. It should be fast since it's already cached.

So the new code would be:

$("#date_1").hover(function () {
    //$("#magicimage_1").show();
    $("#magicimage_1").show().attr('src', 'assets/img/dates/1_randomhash-aefgh.gif?rnd=' +Math.random()+'');
}, function () {
    //$("#magicimage_1").hide();
    $("#magicimage_1").hide().attr('src', '');
});

As I want to remove the SRC on hover out.. so it plays fully
