如何将 jQuery 插件应用于 JavaScript DOM 元素？
[英]How can I apply a jQuery plugin to a JavaScript DOM element?
问题描述
A couple of days ago I had a question about the use of a library called select2, that in the official documentation for its installation and use you have to obtain the element through jquery $('.mySelect').select2();
几天前，我有一个关于使用一个名为 select2 的库的问题，在其安装和使用的官方文档中，您必须通过 jquery $('.mySelect').select2();获取元素。 my doubt is what it does exactly when you do this action .select2();我怀疑当您执行此操作时它到底做了什么.select2(); (in a technical way) to the element and what would be the equivalent action doing it with document.getElementById('mySelect') . （以技术方式）对元素以及使用document.getElementById('mySelect')执行的等效操作是什么。

It's a jQuery-Plugin .这是一个jQuery-Plugin 。 Underlying there is a function which has a reference to your selected element ( .mySelect ) in the this statement.底层有一个 function ，它在this语句中引用了您选择的元素 ( .mySelect )。 Take a look here for more information https://learn.jquery.com/plugins/basic-plugin-creation/在这里查看更多信息https://learn.jquery.com/plugins/basic-plugin-creation/

Select2 is based on Jquery, can't use Select2 without Jquery. Select2 基于 Jquery，没有 Jquery 不能使用 Select2。
