1. Native js gets the DOM node: document.querySelector (selector) document.getElementById (id selector) document.getElementsByClassName (class selector).... 2. Get the instance object of the current component in vue2: because each vue Each component instance contains a $refs object, which stores references to the corresponding DOM elements or components. So by default, the component's $refs point to an empty object. You can first add ref="name" to the component, and then pass this.$refs.

In web development, DOM (DocumentObjectModel) is a very important concept. It allows developers to easily modify and operate the HTML or XML document of a web page, such as adding, deleting, modifying elements, etc. The built-in DOM operation library in PHP also provides developers with rich functions. This article will introduce the DOM operation guide in PHP, hoping to help everyone. The basic concept of DOM DOM is a cross-platform, language-independent API that can

Vue3ref binding DOM or component failure reason analysis scenario description In Vue3, it is often used to use ref to bind components or DOM elements. Many times, ref is clearly used to bind related components, but ref binding often fails. Examples of ref binding failure situations The vast majority of cases where ref binding fails is that when the ref is bound to the component, the component has not yet been rendered, so the binding fails. Or the component is not rendered at the beginning and the ref is not bound. When the component starts to render, the ref also starts to be bound, but the binding between ref and the component is not completed. At this time, problems will occur when using component-related methods. The component bound to ref uses v-if, or its parent component uses v-if to cause the page to

Role and function. The main function of BOM is to operate the browser window. It provides direct access and control of the browser window. The main function of DOM is to convert the web document into an object tree, allowing developers to Use this object tree to obtain and modify the elements and content of the web page; 2. Relationship with JavaScript, etc.
