如何添加字符串到jQuery选择器? [英] How to add string to jQuery selector?
问题描述
我正在尝试选择在同一网页的不同帖子上更改的ID。因此,他们被赋予了id =show_posts_ {PostID} - 在最终输出中,{PostID}被替换为一个数字。在函数中,我需要调用 $('show_posts_XXXXXX')
- XXXXXX是生成的ID。我已经将这个ID存储在一个变量postId。
I'm trying to select an id that changes on different posts of same page. So the they have been given an id="show_posts_{PostID}" - on the final output the {PostID} is replaced with a number. In the function I need to call $('show_posts_XXXXXX')
- XXXXXX being the generated ID. I have stored this ID in a variable called postId.
但我不能这样做 $('+show_posts_ + postId +')
任何人都可以告诉我如何在选择器的末尾添加一个字符串?
Can anyone tell me how I can add a string to the end of a selector?
推荐答案
应该工作。如果是,你会踢你自己。不要忘记ID的哈希,并且不需要额外的引号。
Should work. If it does, you'll kick yourself. Don't forget the hash for the ID, and the extra quotation marks aren't necessary.
$("#show_posts_" + postId)
