Can Vue projects carry information when jumping to HTML?

In Vue projects, we often need to jump to other pages, including jumping to HTML pages. Sometimes we need to carry some information when jumping, such as user ID, product ID, etc., so that we can obtain and perform related operations on the target page. So the question is, can the Vue project carry information when it jumps to the HTML page? This article will explore this issue through examples.

There are usually two ways to jump to an HTML page in a Vue project, one is to jump through Vue Router, and the other is to jump through a tag. Next we will analyze these two methods in detail.

Jump through Vue Router

Vue Router is the official routing manager of Vue.js, which can quickly and easily implement the jump function in Vue projects. In the Vue project, we can use Vue Router to jump to the HTML page and carry information at the same time.

Code Example

Suppose we have a Vue project, which defines a user list page UserList.vue. We need to jump to an HTML page in the user list page and carry the current user ID. We can achieve this through the following code:

<template>
  <div>
    <ul>
      <li v-for="user in userList" :key="user.id">
        <router-link
          :to="{
            path: '/info.html',
            query: { userId: user.id }
          }"
        >
          {{ user.name }}
        </router-link>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      userList: [
        { id: 1, name: 'Tom' },
        { id: 2, name: 'Jerry' },
        { id: 3, name: 'Mike' }
      ]
    }
  }
}
</script>

In this example, we use the router-link component provided by Vue Router to implement the jump function. In the to attribute, we use the path parameter to specify the path to the HTML page to jump to, and the query parameter to carry the current user's ID.

In the HTML page, we can obtain the query parameters through JavaScript's window.location.search to obtain the current user's ID. For example, we can use the following code in the info.html page to get the current user's ID:

const searchParams = new URLSearchParams(window.location.search)
const userId = searchParams.get('userId')

Result Analysis

Through the above code example, we can find that jumping in Vue Router Information can be carried when going to the HTML page. We can use query parameters to carry information when jumping, and obtain this information through JavaScript in the target page.

Jump through a tag

In addition to using Vue Router to jump, we can also use HTML's a tag to implement the jump function. Different from Vue Router, a label jump does not require routing configuration and can be simpler and faster. But in terms of carrying information, a tag needs to be implemented using other methods.

Code Example

Suppose we need to jump to an HTML page info.html in the Vue project and carry the current user's ID. We can achieve this through the following code:

<template>
  <div>
    <ul>
      <li v-for="user in userList" :key="user.id">
        <a :href="`/info.html?userId=${user.id}`" target="_blank">
          {{ user.name }}
        </a>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      userList: [
        { id: 1, name: 'Tom' },
        { id: 2, name: 'Jerry' },
        { id: 3, name: 'Mike' }
      ]
    }
  }
}
</script>

In this example, we use the a tag to implement the jump function. In the href attribute, we use a template string to splice the jump link, and use a query parameter to carry the current user's ID. In the target attribute, we set _blank to let the browser open the target page in a new tab.

In the HTML page, we can also use JavaScript's window.location.search to obtain the query parameters and obtain the current user's ID.

Result Analysis

Through the above code examples, we can find that although a label jump does not require the use of Vue Router, other methods need to be used to carry information. We can use query parameters to carry information and obtain this information through JavaScript in the target page.

Summary

Through the above analysis, we can conclude that the Vue project can carry information when jumping to the HTML page. We can use Vue Router or a tag to implement the jump function and carry information through query parameters. In the target page, we can obtain and manipulate this information through JavaScript. In specific development, we need to choose different methods to implement jumps and information carrying according to actual needs.
