div 的调整大小被忽略 [英] Resize of div is being ignored
问题描述
我有一个超级简单的网页，它将数据从服务器加载到作为容器的 s 中.问题是有时图像太高，溢出并导致布局问题.因此，我希望使用以下方法调整 div 的大小:
I have a super-simple web page that loads data from a server into s as containers. The problem is that sometimes images are too tall, and overflow and cause layout problems. So, I was looking to resize the divs using:
target.style.height = height; // As short form of:
document.getElementById('someId').style.height=height;
但到目前为止，我尝试过的一切都没有奏效.这是 html 文件:
But so far NOTHING I've tried has worked. Here's the html file:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<body bgcolor="#E3FBFF" text="#000000" onload="loadImages();">
<script type = "text/javascript">
function loadImages()
{
...Function omitted for brevity...
But it gets to this line:
document.getElementById(d0).style.height = height+10;
}
</script>
<div id=d0></div>
<hr>
<div id=d1></div>
<hr>
<div id=d2></div>
<hr>
<div id=d3></div>
<hr>
</body>
</html>
就是这样！
I have found various articles like this one, or this one, but, they weren't helpful.
我突然想到，在我的情况下，我不需要使用 div 本身.我只需要图像和相关文本不要垂直(或水平)重叠.事实上，当图像加载时，它可能是一团糟....我怎么能告诉我的 div 是全宽的，没有其他 div 的覆盖?我尝试使用类、使用 CSS 等等，但都被忽略了.
It occurs to me to mention that in my case I don't require the use of divs per se. I just need the images and related text to not overlap vertically (or horizontally). As it is, when the images load, it can be a real mess. ...How can I tell my divs to be full width with no overlay from the other divs? I tried using a class, using CSS, and more, all ignored.
我想我是在不正确的假设下工作的，即 div 作为面向块的事物，即使您声明全宽(宽度 = 100%")也可以并且仍然会垂直重叠，具体取决于放置在
I guess I was working under the improper assumption that divs, as block-oriented things, that even if you declare full width ("width=100%") can and will STILL overlap vertically depending on the contents placed in them.
推荐答案
您没有显示分配给高度"的内容，但从您的代码中我假设它是一个整数.
you didnt show what you assigned to 'height', but from your code i assume its an interger.
document.getElementById(d0).style.height = height+10;
style 需要一个字符串(即 10px)，所以给它赋值是行不通的，试试下面的方法
style takes a string (ie 10px), so assigning number to it won't work, try the following
document.getElementById(d0).style.height = height+10+'px';
javascript 会为您将其转换为字符串
