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

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')
