How do I emit multiple arguments via setup()?-CodePudding

I have the following function being passed as an emit to the component:

setTray(tray, pk) {
  alert(tray)
  alert(pk)
},

Calling inside a component, I am able to reach the function, but not the arguments:

setup(props, ctx) {
  ctx.emit('setTray', 'profile-task', pk)
  ctx.emit('setTray', {tray: 'profile-task', pk: pk})
}

Both approaches result in the arguments being undefined when setTray() is executed. What is the correct syntax in this situation?

CodePudding user response：

The emit function accepts one or two arguments, the event name and the payload which in your case should be defined as object :

ctx.emit('setTray', {tray: 'profile-task', pk: pk})

in parent :

setTray({tray, pk}) {//destruct the payload
  alert(tray)
  alert(pk)
},

or in old way :

setTray(payload) {
  alert(payload.tray)
  alert(payload.pk)
},
