Some questions about navigation switching between vue and mint-ui

I was recently working on a mobile page, and then introduced the mint-ui library to do tab switching, and now there is such a problem; There are a total of three tab switching pages on the page, the default is the enterprise information page, I want to click next and jump to the next page, that is, the legal person information page, and then my idea is to bind the click event on the next tab and click to increase the selected by 1, but when I find that the selected is added, the content in the tab-container will be hidden; what do the gods do?

selected
