如何使用 jQuery 将活动状态动态添加到图库缩略图

发布于 2024-09-07 13:12:57 字数 376 浏览 4 评论 0原文

我正在使用 galleriffic 来处理我的图片库，但我在缩略图活动状态方面遇到问题。

Galleriffic 不支持图像上的活动状态 - 仅支持列表项。现在，图库将为包含缩略图的当前 LI 分配一个“选定”类，我一直在尝试使用 jQuery 来定位活动 LI 中的缩略图 ID，因此我为图像分配一个活动状态，然后将其返回到默认状态。

本质上我正在做：

$('.selected img#myImage').attr('src', 'path_to_active_state.jpg');

这有效，但是，我无法让图像恢复到默认值。我不认为 jQuery 支持在 if 语句中使用 hasClass，但如果有人知道请帮忙。欢迎任何建议。

I'm using galleriffic to handle my image gallery and I'm having a problem with the thumbnail active states.

Galleriffic doesn't have support for active states on the images - only the list items. Right now the gallery will assign a "selected" class to the current LI containing the thumbnail and I've been trying to use jQuery to target the thumbnail ID within the active LI so I assign an active state to the image and then return it to the default state.

Essentially I'm doing:

$('.selected img#myImage').attr('src', 'path_to_active_state.jpg');

Which works, however, I can't get the image to go back to the default afterward. I don't think there's jQuery support for using hasClass in an if statement, but if someone knows please help out. Any advice is welcomed.

您可以尝试一下 :not 选择器吗？您当前正在执行此操作以获取选定的图像：

$('.selected img#myImage').attr('src', 'path_to_active_state.jpg');

尝试执行此操作以获取未选定的图像：

$(':not(.selected) img#myImage').attr('src', 'path_to_active_state.jpg');

Could you try the :not selector? You're currently doing this to get the selected image:

$('.selected img#myImage').attr('src', 'path_to_active_state.jpg');

Try doing this to get the unselected image:

$(':not(.selected) img#myImage').attr('src', 'path_to_active_state.jpg');

您可以向活动图像添加一个类，以便稍后可以识别它。

因此

$('.selected img#myImage').attr('src', 'path_to_active_state.jpg').addClass('altered');

，当在示例中突出显示另一个缩略图时

$('.altered').attr('src', 'path_to_inactive_state.jpg').removeClass('altered');

$('.selected img#myImage') 似乎暗示您对所有缩略图使用相同的 ID (#myImage)。 Id 在 DOM 中应该是唯一的。

You could add a class to the active image, so that you can identify it later..

$('.selected img#myImage').attr('src', 'path_to_active_state.jpg').addClass('altered');

and when highlighting another thumbnail

$('.altered').attr('src', 'path_to_inactive_state.jpg').removeClass('altered');

also in your example $('.selected img#myImage') seems to imply that you use the same id for all thumbnails (#myImage). Id's should be unique inside the DOM..
