How does the navbar of mint-ui get the current clicks?

how does the navbar of mint-ui get the current clicks? what I want to achieve is that users click on different tab to send requests and request different data. Previously, using tabs, in element-ui provided a click event to get the current clicks. I see that there is no specific description in the mint-ui document, only that there is a value, but how to get this value
