This article mainly introduces the relevant knowledge of "how nuxt.js monitors routing". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how nuxt.js monitors routing" can help you solve the problem.

Requirements: click on a category on the current page to change the routing parameters

For example: change from this route / detail?targetId=2 to / detail?targetId=3

At this time, the first thing I thought of was watch listening for routing, but because it was server rendering, I couldn't get the this object for the first time, and always reported that this.$axios did not exist.

So at this time, look up the watchQuery in the document.

API: The watchQuery Property

WatchQuery (newQuery, oldQuery) {

Console.log (this)

Let detail

If (this) {

Detail = (this.$axios.get (--${detailUrl} ${newQuery.targetId}--) .data

Console.log ("newQuery", newQuery, oldQuery, this)

}

Return {

Detail

}

}

There's a big hole here, that is, detail is going back out.
