There are three ways for vue to pass parameters: 1, use the name attribute of the route to pass parameters, and receive parameters through "$route.name"; 2, pass parameters through the to attribute in router-link; 3, use path to match routing components, and use url to pass parameters.
The operating environment of this tutorial: windows7 system, vue2.9.6 version, DELL G3 computer.
The first one: using name to pass
In the past, there has been a name when configuring routing, but I don't know what its specific use is. In routing, it can be used to pass parameters. Write the name of the route in index.js
Receive parameters:
Add it to the page where we need to receive it
I am router-name: {{$route.name}}
For example, I received it here in APP.vue, and I want to see the parameters on every page I switch.
Look at the results:
But this method is not very common because we think it is not very regular.
Second: through the to attribute in router-link
Use to in router-link to pass parameters. Look at the syntax:
a. First: to needs to be bound
b. Pass parameters in a form similar to that of an object
C.name is the name we chose when configuring routing.
d. Parameters are also in the form of objects.
Do it in practice:
a. Change the path in to to the above in APP.vue
Hellovue page
Here we pay attention to the writing of to, preceded by a colon, because it is bound, pass a username and the value is tomcat
b. Configure hellovue in index.js with the name hellovue, which corresponds to the above name
C. Receive parameters in hellovue.vue
The name passed is: {{$route.params.username}}
Look at the results:
Third: use path to match routing components, and use url to pass parameters
Pass parameters in the form of colons in the routing file, which is the binding of parameters
A. Modify the path in index.js. Here we modify the myjob.vue component
B. Pass parameters in the App.vue component
C. Display what we want to show in the myjob.vue component (receive parameters)
D, look at the results
