Preface
There are many types of route jump parameters in vue. The ones I commonly use are the following ones
Jump through router-link
Route jump through programming navigation
This article mainly introduces it to you Regarding some pitfalls encountered in passing Vue routing parameters, I would like to share them for everyone’s reference and study. I won’t say much below, let’s take a look at the detailed introduction.
First of all, the definition of my route
{
path: '/b',
name: 'B',
component: resolve => require(['../pages/B.vue'], resolve)
}I jump from component A to component B and pass some parameters through the routing information object
this.$router.push({
path: '/b',
params: {
paramA: 'a'
},
query:{
paramB: 'b'
}
})Obtaining parameters in component B
this.$route.query.paramB //b this.$route.params.paramA //undefined
The parameter paramB passed through the params object of the route is always undefined, and the reason can never be found. After consulting the information, I finally found the reason. That is because the route's params object must be called through the route name, but not through the path, and the query object does not have this requirement.
So we modify the code:
this.$router.push({
name: 'B',
params: {
paramA: 'a'
},
query:{
paramB: 'b'
}
})Just replace the path parameter with the corresponding route name. At this time, everything will be normal when getting the parameters.
this.$route.query.paramB //b this.$route.params.paramA //a
The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
