There is no component content after the vue route jumps

Vue.js is one of the very popular front-end frameworks at the moment. Its elegant syntax and simple component-based development method have been widely welcomed. However, when using Vue.js to develop applications, developers may encounter some problems. One of the common problems is that the component content is not displayed after the Vue route jumps. In this article, we will discuss the causes and solutions to this problem.

1. Cause

When the component content is not displayed after the vue route jumps, the root cause is that the route is not configured correctly or used correctly. The following are some possible reasons for this problem:

1.1 Routing is not configured correctly

In Vue.js, we can use Vue Router for routing management. If an error occurs when configuring a route, it may cause the route to not work properly. Common routing configuration errors include:

1) Undefined routing component

When defining a route, you need to specify the corresponding component so that the route can correctly navigate to the component. If the component is not defined or the component name is spelled incorrectly, the route will not be able to navigate to the component, resulting in the problem that the component content is not displayed.

2) Wrong routing path

The routing path represents the access path of the routing. If the path is not set correctly, the corresponding component cannot be found, and the component content cannot be displayed. Therefore, we need to double check whether the routing path is correct.

1.2 Routing is not used correctly

Even if the routing is configured correctly, if it is not used correctly, it will cause the problem that the component content is not displayed. Possible reasons include:

1) The component is not used

In Vue.js, the component is used to display components matched by the current route . If the component is not used in the corresponding page, the route cannot display the corresponding component correctly. Therefore, we need to check whether the component is used correctly in the corresponding page.

2) The route is not activated

If the route is not activated, you will not be able to navigate to the route. If we use the vue-router-link component to render a navigation link, we need to ensure that the component is active in order to navigate to the route correctly.

2. Solution

If you encounter the problem that the component content is not displayed after the vue route jumps, you should solve it according to the following steps:

2.1 Check Routing configuration

First, we need to check whether the routing is configured correctly. We should confirm that the component name is spelled correctly and check that the routing path is correct. Additionally, in many cases, we may miss defining the corresponding component in the route configuration, which requires checking each route one by one to ensure that they all specify the correct component.

2.2 Using the component

If the routing configuration is correct, but the component content is still not displayed, then we should ensure that the Component. If not used correctly, the component will not display correctly.

2.3 Activate routing

If the component is used correctly, but the component is still not displayed, we need to ensure that the route is activated. We can use the vue-router-link component to render navigation links, in this case we have to ensure the active state of the vue-router-link component. If not activated correctly, the route will not properly navigate to the specified component.

3. Conclusion

When the component content is not displayed after the vue route jumps, the root cause is that the route is not configured or used correctly, resulting in the route being unable to navigate correctly. specified component. In order to solve this problem, we need to carefully check the routing configuration to ensure that the component is used correctly and the route is activated correctly. By following these simple steps, we can easily solve this common Vue.js problem and get our application running properly.
