- How to use trim in vue
- The trim method of Vue.js can remove leading and trailing whitespace characters from a string. The usage is as follows: call the trim method directly.

The trim method is immutable, i.e. it returns a new trimmed string and does not modify the original string.

Implementation method: computed is defined in the form of a function, and method is defined in the form of a regular function. Responsiveness: computed is responsive, method is not. Performance: computed is recalculated only when dependencies change, and method is re-executed every time it is called.

It is used to update the view or perform other operations when the data changes.

- In vue: the role of key
- The key attribute in Vue is used to uniquely identify list elements, helping Vue track element identity, update the DOM correctly, optimize performance, and avoid unnecessary re-rendering. Usage rules include: each element must have a unique and stable string, number, or symbol key; object lists can use the id attribute as the key, and array lists can be used but try to avoid using indexes as the key.

- The role of key in vue
- Key in Vue is used to uniquely identify list items, allowing Vue to effectively track and update list items, optimize Virtual DOM updates, and force re-rendering. Best practices include ensuring that the Key is unique and immutable, preferring an attribute related to the list item's identity, or using a random UUID or timestamp.

- What attributes are used to obtain dom elements in vue
- You can obtain a reference to a DOM element through the ref attribute in Vue. The specific steps are as follows: define a reference variable and add it to the ref attribute of the DOM element to be referenced. Use the $refs object in the mounted hook to access DOM elements. Note: Reference variables must be defined before the component is instantiated, DOM elements can only be accessed in the mounted hook, and the $refs object is read-only.

- The role of nexttick in vue
- Answer: nextTick in Vue.js is an asynchronous update queue that is used to delay the execution of callback functions until the DOM update is completed. Detailed description: Role: Update view: Ensure safe manipulation of elements after DOM updates. Asynchronous operations: Delay code execution to avoid blocking rendering. Data response: Ensure that actions are performed after the data has been updated. How it works: Push the callback function into the asynchronous update queue and execute it after the DOM is updated. Usage: Syntax: Vue.nextTick(callback) The callback function will be executed after the DOM is updated.

- The difference between v-model and v-bind in vue
- The main difference between v-model and v-bind in Vue is: Purpose: v-model is used for two-way binding of the value of form elements, and v-bind is used for one-way binding of attributes or HTML elements. Syntax: v-model uses the "v-model" directive, v-bind uses a colon prefix, such as ":value". Two-way/one-way binding: v-model allows two-way binding, while v-bind only allows one-way binding. Responsiveness: v-model is more responsive, changes to the data are immediately reflected on the interface. Form elements: v-model is mainly used for form elements, while v-bind can be used for any attribute or H
