如何使我的脚本只影响它在jquery中自己的图像

How to make my script affects only it's own image in jquery?

本文关键字:jquery 自己的 图像 影响 何使 我的 脚本      更新时间:2023-09-26

我正在尝试实现SpaceGallery脚本。万维网:http://www.eyecon.ro/spacegallery/。它从 #div 中获取图像,并使幻灯片像在线演示一样。我的 HTML 文件的一部分:

    <div id="myGallery0" class="spacegallery">      
<img class="imaz" src="ADDITIONAL.jpg" alt="" atr1="lupa" />    
<img class="aaa" src=images/bw1.jpg alt="" atr1="bw1" />
<img class="aaa" src=images/bw2.jpg alt="" atr1="bw2" />
<img class="aaa" src=images/bw3.jpg alt="" atr1="bw3" />
            </div>
        <div id="myGallery1" class="spacegallery">      
<img class="imaz" src="ADDITIONAL.jpg" alt="" atr1="lupa" />
<img class="aaa" src=images3/bw1.jpg alt="" atr1="bw1" />
<img class="aaa" src=images3/bw2.jpg alt="" atr1="bw2" />
<img class="aaa" src=images3/lights2.jpg alt="" atr1="bw3" />
            </div>
            <script>
    var initLayout = function() {
        $('#myGallery0').spacegallery({loadingClass: 'loading'});
        $('#myGallery1').spacegallery({loadingClass: 'loading'});
                };  
        EYE.register(initLayout, 'init');
            </script>

现在,当我调用 $('img.aaa')时,脚本运行良好!该脚本仅滑动其自己的 ID(mygallery0 或 mygallery1)中的图像。假设我的主.js文件中有以下 .onclick 内容。

         $('img.imaz').fadeOut();

当我在我的一个画廊(mygaller0 或 mygallery1)中滑动图像时,img "ADDITIONAL.jpg"(它的类 = imaz)在我的所有画廊中淡出!为什么?如何解决?

太空画廊.js

您可以尝试通过将this作为第二个参数传递给选择器来尝试将匹配的图像限制为当前元素的上下文。

defaults: {
    /* options */
    before: function(){
        $('img.imaz', this).fadeOut();
    },
    after: function(el){    
        $('img.imaz', this).fadeIn();
    }
}

当我们传入this时,作为选择器中的第二个参数,我们告诉jQuery以"img.imaz"为目标,但只有当它this中找到时,这意味着当前正在处理的元素。在您的项目中,这将是 #myGallery0#myGallery1
