as shown in the figure: delete a group on the grouping page, then click on the device management page, or click back to the previous page (device management page)
this needs to be refreshed. If the grouping page does nothing, jump to the device management page to use the page"s cache.
the current way to handle this is to define a global variable first, give the variable true, as long as you operate on the grouping in a page, and then do so in the beforeRouteLeave hook function.
beforeRouteLeave (to, from, next) {
if (this.flagKeepAlive==true&&to.path=="/device") {
to.meta.keepAlive = false;
}
else {
to.meta.keepAlive = true;
}
next();}
