作为jQuery选择器的字符串数组？ [英] an array of strings as a jQuery selector?

问题描述

我有一个有效jQuery选择器的字符串数组（即页面上元素的ID）：

I have an array of strings that are valid jQuery selectors (i.e. IDs of elements on the page):

["#p1", "#p2", "#p3", "#p4", "#p5"]

我想在jQuery数组中选择带有这些ID的元素。这可能是基本的，但我在网上找不到任何东西。我可以有一个for循环，它创建一个字符串＃p1，＃p2，＃p3，＃p4，＃p5然后可以作为单个传递给jQuery选择器，但不是另一种方式？有没有办法将一个字符串数组作为选择器传递？

I want to select elements with those IDs into a jQuery array. This is probably elementary, but I can't find anything online. I could have a for-loop which creates a string "#p1,#p2,#p3,#p4,#p5" which could then be passed to jQuery as a single selector, but isn't there another way? Isn't there a way to pass an array of strings as a selector?

编辑：实际上，有一个已经有了答案。

推荐答案

好吧，有'加入'：

["#p1", "#p2", "#p3", "#p4", "#p5"].join(", ")

编辑 - 额外信息：

可以选择一个元素数组，问题在这里你没有元素，只是选择器字符串。无论你如何切片，你都必须执行像.getElementById这样的搜索或使用实际的jQuery选择。

It is possible to select an array of elements, problem is here you don't have the elements yet, just the selector strings. Any way you slice it you're gonna have to execute a search like .getElementById or use an actual jQuery select.
