Find all elements by part of the id attribute
提问by mousesports
I was wondering if this was possible:
我想知道这是否可能：
I have a set of divs, each with an ID ending in '_font', e.g 'body_font', 'heading_font', 'tagline_font', etc.
我有一组 div，每个 div 的 ID 都以“_font”结尾，例如“body_font”、“heading_font”、“tagline_font”等。
Is there a way to grab those elements by searching for a common portion of their names, in this case '_font' so I can later manipulate them using jQuery?
有没有办法通过搜索它们名称的公共部分来获取这些元素，在这种情况下是“_font”，以便我以后可以使用 jQuery 操作它们？

You can use an "attribute ends-with" selector:
您可以使用“属性结束”选择器：
var elems = $("div[id$='_font']");
If you spend some time browsing the jQuery API you should be able to answer questions like this yourself without having to post on Stack Overflow.
如果您花一些时间浏览 jQuery API，您应该能够自己回答这样的问题，而无需在 Stack Overflow 上发帖。
