重新加载动画 Gif 缓存每个 jQuery 悬停 [英] Reload Animated Gif cache each jQuery hover

问题描述

不同于:从 JavaScript 重新启动动画 GIF无需重新加载图像

我有一个简单的动画 gif 图标，可以播放一次(它不会重复循环)

我把它放在一个 DIV 里.当用户将鼠标悬停在 DIV 上时，我想播放 GIF.当他们搬出时，DIV 关闭.当移动回来时，我希望他们再次播放 GIF - 我可以在 jQuery 上使用强制缓存吗:

HTML:

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

jQuery:

 $("#date_1").hover(function () {$("#magicimage_1").show();}， 功能 () {$("#magicimage_1").hide();});//考虑过这些/*var myImg = new Image();myImg.src = "image.gif?rnd=" + Math.random();img src="filename.gif?rand=<#?=rand(1,1000);?>"alt=""*/

解决方案

我更新了旧代码以显示重置的图像.它应该很快，因为它已经缓存了.

http://jsfiddle.net/gYmvN/4/

所以新代码将是:

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

因为我想在悬停时移除 SRC ......所以它可以完全播放

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=""
*/ 

解决方案

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

http://jsfiddle.net/gYmvN/4/

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
