javascript - 根据图片大小设置div高度

标签 javascript php jquery html css

所以我在我的 php 代码中填充了三个 javascript 数组，以保存照片的尺寸及其来源。然后，假设尺寸不等于使用 php 的 325x300，我只会在我的页面上显示图像的 325x300 缩略图。

当用户单击其中一个缩略图时，我希望它在 #largeImage div 中打开全尺寸图像，然后取消隐藏它。到目前为止，这是可行的。

但是，我在让潜水调整图像尺寸时遇到了麻烦。我正在使用 php 来获取尺寸(除非在 jQuery 中有更好的方法)。此时 div 没有调整大小，我不确定从这里去哪里。我已经包含了 jquery 和来自 php 代码的输出 html。

                $('#largImage').height(parseInt(picture_y[index]) + 20);
                $('#largImage').width(parseInt(picture_x[index]) + 50);
                $('#largeImage img').attr('src', picture_list[index]);

这是我目前正在使用的 CSS。如果我删除 jQuery block 中的大小限制，div 不会调整大小。

最佳答案

删除行:

$('#largImage').height(parseInt(picture_y[index]) + 20);
$('#largImage').width(parseInt(picture_x[index]) + 50);

并让#largeImage 自动调整大小以适合图像。您可以使用 CSS(最大宽度、最大高度)控制 #largeImage 的最大尺寸。
