Although it doesn't precisely answer the question, I landed here when searching for a way to get the collection of elements (potentially different tag names) that simply had a given attribute name (without filtering by attribute value). I found that the following worked well for me:
虽然它没有准确地回答这个问题，但我在寻找一种方法来获取元素集合（可能是不同的标签名称）时，我来到这里，这些元素只有一个给定的属性名称（没有按属性值过滤）。我发现以下对我来说效果很好：
$("*[attr-name]")
Hope that helps somebody who happens to land on this page looking for the same thing that I was :).
希望能帮助那些碰巧在此页面上寻找与我相同的东西的人:)。
Update: It appears that the asterisk is not required, i.e. based on some basic tests, the following seems to be equivalent to the above (thanks to Matt for pointing this out):
更新：似乎不需要星号，即基于一些基本测试，以下内容似乎与上述内容相同（感谢 Matt 指出这一点）：
$("[attr-name]")

$('div[imageId="imageN"]').each(function() {
// `this` is the div
});
To check for the sole existence of the attribute, no matter which value, you could use ths selector instead: $('div[imageId]')
要检查属性是否存在，无论是哪个值，都可以使用 ths 选择器： $('div[imageId]')

It's not called a tag; what you're looking for is called an html attribute.
它不称为标签；您要查找的内容称为 html 属性。
$('div[imageId="imageN"]').each(function(i,el){
$(el).html('changes');
//do what ever you wish to this object :)
});

You can use partial value of an attribute to detect a DOM element using (^) sign. For example you have divs like this:
您可以使用属性的部分值来使用 (^) 符号检测 DOM 元素。例如你有这样的 div：
<div id="abc_1"></div>
<div id="abc_2"></div>
<div id="xyz_3"></div>
<div id="xyz_4"></div>...
You can use the code:
您可以使用以下代码：
var abc = $('div[id^=abc]')
This will return a DOM array of divs which have id starting with abc:
这将返回一个 DOM div 数组，其 id 以abc以下内容开头：
<div id="abc_1"></div>
<div id="abc_2"></div>

Use string concatenation. Try this:
使用字符串连接。尝试这个：
$('div[imageId="'+imageN +'"]').each(function() {
$(this);
});
