How to solve the failure after using vue.js routing

小云云Original: 2018-05-21 11:15:161967browse

I have newly learned routing in vue.js and added a simple routing example to the vue demo I wrote before ( from vue-router 2), but after adding the click, only the address bar changes. , the content has not changed. And some effects written before with jquery have also failed. Finally, the reason was found because the same id was started twice (the first time was started when using the vue component before, and the other was started when routing of).

Attach part of the code
