推荐答案

您可以使用以选择器^= 开头，如下所示:

You can use the starts with selector ^= like this:

$('div[id^=testDiv]').css('visibility', 'visible'); 

说明:选择要 具有带有 以给定值开头的值 字符串.

Description: Selects elements that have the specified attribute with a value beginning exactly with a given string.

注意 ，如果您改用类，则可以轻松地将它们作为目标，但这取决于您的要求.

Note that if you use a class instead, you can target them easily but that depends on your requirements.
