React mock data method: First create the [/api/headerList.json] file in the public directory; then add the relevant code [axios.get('/api/headerList.json')].
#The operating environment of this tutorial: windows7 system, React17 version, thinkpad t480 computer.
React mock data method:
The following code calls the getList()
method when the input gains focus.
const mapDispathToProps = (dispatch) => { return { handleInputFocus() { dispatch(actionCreators.getList()) } } }
The getList() method obtains data through Ajax. At this time, the backend has not been written yet, so I mock the data myself.
export const getList = () => { return (dispatch) => { axios.get('/api/headerList.json').then((res) => { const data = res.data; console.log(data) }).catch(() => { console.log('error') }) } }
axios.get('/api/headerList.json')
With this code, the computer will first go to the src directory to look for /api/headerList.json. If it is not found, it will go to public Find it in the directory. At this time, we create the /api/headerList.json file in the public directory. The file is as follows:
{ "success":true, "data":["微信","支付宝","蚂蚁金服","被骗","借呗","诈骗","盗窃","pandas","TensorFlow","PyTorch","Caffe","scikit-learn","Python","Keras","pyecharts","ggplot","Matplotlib","Gensim","Bokeh","Theano","Scrapy","SciPy","Plotly","NumPy","XGBoost","是","他","有","光大永明","我","要","人","Android","女","大","不","着","男","它","二","于","中","java","把","上","这","下","的","了","来"] }
The data returned at this time is the above data, through console.log(res.data )
Print the data as shown below:
In this way, the mock data will be successful.

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

The power of the JavaScript framework lies in simplifying development, improving user experience and application performance. When choosing a framework, consider: 1. Project size and complexity, 2. Team experience, 3. Ecosystem and community support.

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting.
