我不是 javascript 开发人员，但我得到了一些调试代码。请多多包涵。基本上，我正在处理的 iOS 模块中有一个 .js CSS 文件集。图片当前加载不正确，导致需要水平滚动。
这是我的代码。您可以看到样式设置为 block 显示，但这没有提供所需的输出。
function resizeImages(container, maxWidth) {
var images = container.getElementsByTagName('img');
for (var i = 0; i < images.length; i++) {
var img = images[i];
var width = parseInt(window.getComputedStyle(img, null).getPropertyValue('width'));
var height = parseInt(window.getComputedStyle(img, null).getPropertyValue('height'));
if (width > maxWidth) {
var ratio = maxWidth / width;
img.style.width = (maxWidth - 30) + "px";
// Some image heights are set to 'auto' so they do not need their height set
if (height != 0) {
img.style.height = parseInt(height * ratio) + "px";
}
}
img.style.display = "block";
img.style.marginLeft = "auto";
img.style.marginRight = "auto";
}
}
是否可以在此函数中设置布局，还是我必须寻找其他方法？
谢谢你的帮助

最佳答案
我最终使用其中一条评论作为答案。代码在 css 文件中看起来像这样
img {
max-width: 98%;
height: auto;
}
