Vue- variables inside event bus are not reactive










0















I created global event bus



Vue.prototype.$eventHub = new Vue()


In 'component 2' clicking on the button, emitted the event then navigating to 'component 1'



this.$eventHub.$emit('deleted')


In another 'component 1' i am trying to use it



data: function () 
return
testVariable : true

,
beforeMount ()
var self = this
this.$eventHub.$on('deleted', function ()
console.log("executed")
self.testVariable = false
)



In the template section i used testVariable, it's always displaying true. Why it is not reactive? what did i miss?

    I think you misunderstood how the event works. The event listener has to exist when the event is emitted. Which means component 1 and component 2 has to exist at the same time.

    Since you want to navigate from 1 route to another, you can either 1) store the shared state in Vuex, 2) pass the boolean value through a url param for e.g. url?testVariable=true
