用不同的图像替换单选按钮

我需要创建一组 2 个单选按钮（选项：男/女）来显示图像而不是实际按钮。图像应根据选择而变化。所以应该有 4 个图像：男性（开）、男性（关）、女性（开）、女性（关）。

我在整个网站中使用 jQuery，如果可能的话，我也想使用 jQuery。

我发现了各种可以替换表单控件的插件，并且我正在使用图像勾选对于复选框替换，效果很好。但是，我不知道如何调整该插件，因此我可以在一个单选按钮组中使用不同的图像。

Thanks!

我修改了插件以满足您的需求。现在，它可以根据每个单选按钮的状态显示自定义图像。如果您发现任何错误，请评论:)

使用（对于称为gender，带有选项值male and female):

$("input[name='gender']").imageTick({
    tick_image_path: { 
        male: "images/gender/male_checked.jpg", 
        female: "images/gender/female_checked.jpg"
        //"default": "images/gender/default_checked.jpg" //optional default can be used
    },
    no_tick_image_path: { 
        male: "images/gender/male_unchecked.jpg", 
        female: "images/gender/female_unchecked.jpg"
        //"default": "images/gender/default_unchecked.jpg" //optional default can be used
    },
    image_tick_class: "gender",
});
