Difference: 1. "v-bind" is a one-way binding, while "v-model" is a two-way binding; 2. "v-bind" can only synchronize data in vue to the page. And "v-model" can not only synchronize data in vue to the page, but also assign user data to attributes in vue.

The operating environment of this tutorial: windows7 system, vue2.9.6 version, DELL G3 computer.
The difference between v-model and v-bind:
1. v-bind is a one-way binding, used to bind data and Properties and expressions can only synchronize data in vue to the page.
2. v-model is a two-way binding. It can not only synchronize data in vue to the page, but also assign user data to attributes in vue.
3. v-bind can assign a value to any attribute, while v-model can only perform two-way data binding for elements with a value attribute.
1. v-model
v-model is mostly used in forms. It creates two-way binding on form elements and chooses the correct method to update elements according to the type of control. It can bind text, radio, checkbox, selected
1. Bind text
<input>
<p> {{val}} </p>
2. Bind radio
<input type="radio" value="one" v-model="radioVal" /> <input type="radio" value="two" v-model="radioVal" /> <label for v-bind="radioval" />
radioval value as the radio button is selected The value will become one or two
3. Bind checkBox
(1) A single check box, the final value is the logical value true and false
<input type="checkbox" v-model="checkVal"/>
<label for="checkbox">{{checkVal}}</label>(2) When there are multiple check boxes, bind the value to an array
<input type="checkbox" value="apple" v-model="checkArray"/>
<label for="checkbox">{{apple}}</label>
<input type="checkbox" value="banana" v-model="checkArray"/>
<label for="checkbox">{{banana}}</label>
<input type="checkbox" value="pear" v-model="checkArray"/>
<label for="checkbox">{{pear}}</label>
<span>{{checkArray | json}}</span>The value in checkArray will change relatedly depending on whether it is selected
4. Bind select
(1) Bind to a single select
(2) When binding multiple selects, the same applies to the array
5. Add Parameters
(1) lazy
Change the input event of the input box to the change event, so that the input box is updated in the change event instead of input
About change The difference between events and input events, simply put:
change events must be triggered after the input box loses focus, while input events can be monitored in real time.
(2)number
Change the values entered in the text box into numbers. If it is changed to a number followed by NAN, return the original value
(3)trim
Get the leading and trailing spaces of the input string
2. v-bind
1. Bind text
Use v-bind directly or {{}}
<p v-bind="message"></p>
<p>{{message}}</p>2. Bind attributes
<p v-bind:src="http://...."></p> <p v-bind:class="http://...."></p> <p v-bind:style="http://...."></p>
3. Bind expression
{{ number + 1 }}
{{ ok ? 'YES' : 'NO' }}
{{ message.split('').reverse().join('') }}4. Bind html
<div>{{{ raw_html }}}</div>At this time, you must use three {}

React Inside HTML: Integrating JavaScript for Dynamic Web PagesApr 16, 2025 am 12:06 AMTo integrate React into HTML, follow these steps: 1. Introduce React and ReactDOM in HTML files. 2. Define a React component. 3. Render the component into HTML elements using ReactDOM. Through these steps, static HTML pages can be transformed into dynamic, interactive experiences.
The Benefits of React: Performance, Reusability, and MoreApr 15, 2025 am 12:05 AMReact’s popularity includes its performance optimization, component reuse and a rich ecosystem. 1. Performance optimization achieves efficient updates through virtual DOM and diffing mechanisms. 2. Component Reuse Reduces duplicate code by reusable components. 3. Rich ecosystem and one-way data flow enhance the development experience.
React: Creating Dynamic and Interactive User InterfacesApr 14, 2025 am 12:08 AMReact is the tool of choice for building dynamic and interactive user interfaces. 1) Componentization and JSX make UI splitting and reusing simple. 2) State management is implemented through the useState hook to trigger UI updates. 3) The event processing mechanism responds to user interaction and improves user experience.
React vs. Backend Frameworks: A ComparisonApr 13, 2025 am 12:06 AMReact is a front-end framework for building user interfaces; a back-end framework is used to build server-side applications. React provides componentized and efficient UI updates, and the backend framework provides a complete backend service solution. When choosing a technology stack, project requirements, team skills, and scalability should be considered.
HTML and React: The Relationship Between Markup and ComponentsApr 12, 2025 am 12:03 AMThe relationship between HTML and React is the core of front-end development, and they jointly build the user interface of modern web applications. 1) HTML defines the content structure and semantics, and React builds a dynamic interface through componentization. 2) React components use JSX syntax to embed HTML to achieve intelligent rendering. 3) Component life cycle manages HTML rendering and updates dynamically according to state and attributes. 4) Use components to optimize HTML structure and improve maintainability. 5) Performance optimization includes avoiding unnecessary rendering, using key attributes, and keeping the component single responsibility.
React and the Frontend: Building Interactive ExperiencesApr 11, 2025 am 12:02 AMReact is the preferred tool for building interactive front-end experiences. 1) React simplifies UI development through componentization and virtual DOM. 2) Components are divided into function components and class components. Function components are simpler and class components provide more life cycle methods. 3) The working principle of React relies on virtual DOM and reconciliation algorithm to improve performance. 4) State management uses useState or this.state, and life cycle methods such as componentDidMount are used for specific logic. 5) Basic usage includes creating components and managing state, and advanced usage involves custom hooks and performance optimization. 6) Common errors include improper status updates and performance issues, debugging skills include using ReactDevTools and Excellent
React and the Frontend Stack: The Tools and TechnologiesApr 10, 2025 am 09:34 AMReact is a JavaScript library for building user interfaces, with its core components and state management. 1) Simplify UI development through componentization and state management. 2) The working principle includes reconciliation and rendering, and optimization can be implemented through React.memo and useMemo. 3) The basic usage is to create and render components, and the advanced usage includes using Hooks and ContextAPI. 4) Common errors such as improper status update, you can use ReactDevTools to debug. 5) Performance optimization includes using React.memo, virtualization lists and CodeSplitting, and keeping code readable and maintainable is best practice.
React's Role in HTML: Enhancing User ExperienceApr 09, 2025 am 12:11 AMReact combines JSX and HTML to improve user experience. 1) JSX embeds HTML to make development more intuitive. 2) The virtual DOM mechanism optimizes performance and reduces DOM operations. 3) Component-based management UI to improve maintainability. 4) State management and event processing enhance interactivity.
