This article mainly introduces the three basic modes of Vue routing parameter transfer in detail, which has certain reference value. Interested friends can refer to it

Routing is a bridge connecting various pages. , and parameters play an extremely important role in it. In a certain sense, they determine whether the two bridges can be successfully connected.

In vue routing, 3 parameter passing methods are supported.

Scenario, click the li element of the parent component to jump to the child component, and carry parameters to facilitate the child component to obtain the corresponding li data and display the corresponding correct content.

In the parent component:

<li v-for="article in articles" @click="getDescribe(article.id)">

Option one:

getDescribe(id) {
// 直接调用$router.push 实现携带参数的跳转
    this.$router.push({
     path: `/describe/${id}`,
    })

// 方案一，需要对应路由配置如下：
  {
   path: &#39;/describe/:id&#39;,
   name: &#39;Describe&#39;,
   component: Describe
  }
// 很显然，需要在path中添加/:id来对应 $router.push 中path携带的参数。

// 在子组件中可以使用来获取传递的参数值。
$route.params.id

Option two:

// 父组件中：通过路由属性中的name来确定匹配的路由，通过params来传递参数。
    this.$router.push({
     name: &#39;Describe&#39;,
     params: {
      id: id
     }
    })

// 对应路由配置: 注意这里不能使用:/id来传递参数了，因为父组件中，已经使用params来携带参数了。
  {
   path: &#39;/describe&#39;,
   name: &#39;Describe&#39;,
   component: Describe
  }

//子组件中: 这样来获取参数
$route.params.id

Option 3:

// 父组件：使用path来匹配路由，然后通过query来传递参数
这种情况下 query传递的参数会显示在url后面?id=？
  this.$router.push({
     path: &#39;/describe&#39;,
     query: {
      id: id
     }
    })

// 对应路由配置：
  {
   path: &#39;/describe&#39;,
   name: &#39;Describe&#39;,
   component: Describe
  }

// 对应子组件: 这样来获取参数
$route.query.id

// 这里要特别注意 在子组件中 获取参数的时候是$route.params 而不是
$router 这很重要~~~

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
