This article mainly introduces the jump between components of vue-router and the parameter transfer method in detail. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.
Use VueRouter to realize jumps between components: parameter transfer, the specific content is as follows
login ---Username--->main
①Clear Sender and receiver
②Configure the routing address of the receiver
{path:'/myTest',component:TestComponent}
-->
{path:' /myTest/:id',component:TestComponent}
③The receiver gets the passed data
this.$route.params.id
④Jump When transferring, send parameters
this.$router.push('/myTest/20')
