Vue $ Implementation method for opening a new window

Recently, a fan friend asked me:$Methods are used to jump routes in the current window, but sometimes we need toOpen a route in a new window or tabHow to implement the change?

Then here are the implementation logic and code cases!

1. How to implement the $ open a new window in Vue

1. Use matching $

In Vue Router, go through directly$Methods cannot open the page in a new window, but we can combineMethods and$Method to implement this function.

methods: {
  openNewPage(routeName) {
    const targetRoute = this.$({ name: routeName });
    (, '_blank');
  }
}

Here,$Method parses the routing object into an object containing the complete URL, from which we extracthrefAttributes for。

2. Dynamically pass parameters

If you need to pass dynamic parameters when opening a new window, you can do so by parsing the route and adding query parameters.

methods: {
  openNewPageWithParams(routeName, params) {
    const targetRoute = this.$({
      name: routeName,
      query: params
    });
    (, '_blank');
  }
}

For example, callopenNewPageWithParams('routeName', { id: 123 })Query parameters will be opened in a new window?id=123page.

3. Handle complex routing structures

For nested routes or complex routing structures with multiple parameters, parse and build URLs in a similar way.

methods: {
  openComplexPage(routeName, params, query) {
    const targetRoute = this.$({
      name: routeName,
      params: params,
      query: query
    });
    (, '_blank');
  }
}

In complex scenarios,paramsandqueryAn object can contain multiple key-value pairs to meet different needs.

4. Consider browser security restrictions

It should be noted that some browsers may block new windows that open through JavaScript, especially without user interaction (such as clicking buttons). Therefore, make sure these methods are called in user actions such as click events.

5. Navigation Guards with Vue Router

Before opening a new window, some verification or processing logic may be required, and Vue Router's navigation guard can be used.

beforeRouteLeave(to, from, next) {
  if (someCondition) {
    next(false); // Block navigation    ('targetRouteName');
  } else {
    next(); // Continue to navigate  }
}

6. Integrate into Vue components

For more convenient use, these methods can be integrated into Vue components and triggered by buttons or other interactive elements.

<template>
  <button @click="openNewPage('targetRouteName')">Open in New Window</button>
</template>

<script>
export default {
  methods: {
    openNewPage(routeName) {
      const targetRoute = this.$({ name: routeName });
      (, '_blank');
    }
  }
}
</script>

2. Design analysis

1. Vue Router's URL resolution mechanism

Vue Router determines the current routing status by parsing the URL and navigates according to the routing configuration.$The method uses this mechanism to resolve the routing object into an object containing the complete URL.

2. Behavior

The method is a native API provided by the browser to open a URL in a new window or tab. Its behavior may be affected by browser settings and user experience policies.
