Jquery 图像切换

发布于 2024-08-04 04:30:25 字数 1101 浏览 2 评论 0原文

我正在为我正在构建的网站使用 Jquery 中的图像切换功能。有大量的项目，所以我对这些图像进行了大量压缩。然而，其中一些 .gif 看起来并不好看，只有制作 .jpg 才有意义。

我的问题是，此代码仅将一个图像交换为另一个名称不同但前缀相似的图像。有没有办法只交换文件名，这样如果我有 .gif 或 .jpg，那没关系，因为它只是将名称从 _static 交换到 _rollover 吗？

这是我正在使用的代码：

//Image Switch
$(document).ready(function(){
    $(".projectThumb img").hover(
            function(){
                    var iconName = $(this).attr("src");
                    var origin = iconName.split("_static.")[0];
                    $(this).attr({src: "" + origin + "_rollover.gif"});
            }, 
            function(){
                    var iconName = $(this).attr("src");
                    var origin = iconName.split("_rollover.")[0];
                    $(this).attr({src: "" + origin + "_static.gif"});
            });
});

以及图像切换的 HTML

<div class="projectThumb">
    <img src="/img/mr_button_static.gif" class="button" name="mr">
    <p class="title">Title &ndash; Poster</p>
</div>

要切换的图像名为 /img/mr_button_rollover.jpg

谢谢！

I am using an image switch function in Jquery for a site I am building. There are a ton of projects so I am heavily compressing a lot of these images. Some of them however dont look nice as .gifs and it really only makes sense to make a .jpg.

My problem is that this code only swaps one image, to another image of a different name but similar prefix. Is there a way to swap just the name of the file, so that if I have a .gif, or .jpg, it wouldn't matter as it would just be swapping the name from _static to _rollover?

Here is the code I am using:

//Image Switch
$(document).ready(function(){
    $(".projectThumb img").hover(
            function(){
                    var iconName = $(this).attr("src");
                    var origin = iconName.split("_static.")[0];
                    $(this).attr({src: "" + origin + "_rollover.gif"});
            }, 
            function(){
                    var iconName = $(this).attr("src");
                    var origin = iconName.split("_rollover.")[0];
                    $(this).attr({src: "" + origin + "_static.gif"});
            });
});

and the HTML for the image switch

<div class="projectThumb">
    <img src="/img/mr_button_static.gif" class="button" name="mr">
    <p class="title">Title – Poster</p>
</div>

The image to be switched is named /img/mr_button_rollover.jpg

Thanks!

只需使用字符串替换即可在图像名称中的静态和翻转之间切换。

//Image Switch
$(document).ready(function(){
    $(".projectThumb img").hover(
            function(){
                    var iconName = $(this).attr("src");
                    var rollover = iconName.replace( /static/, 'rollover' );
                    $(this).attr({ src: rollover });
            }, 
            function(){
                    var iconName = $(this).attr("src");
                    var static = iconName.replace( /rollover/, 'static' );
                    $(this).attr({ src: static });
            });
});

如果图像前缀有可能静态/翻转，只需在搜索和替换字符串中包含下划线，并匹配/替换文件扩展名之前的点。

Just use string replacement to switch between static and rollover in the image name.

//Image Switch
$(document).ready(function(){
    $(".projectThumb img").hover(
            function(){
                    var iconName = $(this).attr("src");
                    var rollover = iconName.replace( /static/, 'rollover' );
                    $(this).attr({ src: rollover });
            }, 
            function(){
                    var iconName = $(this).attr("src");
                    var static = iconName.replace( /rollover/, 'static' );
                    $(this).attr({ src: static });
            });
});

If there is a possibility that you could static/rollover in the image prefix, simply include the underscore in the search and replace strings and match/replace the dot before the file extension.
