Error in call back for watcher, method is not a function

[eugenemaning]

I’m trying to use the watchers as referenced here , however the method call I invoked inside the watcher is not recognized as a function.

I basically followed the guide. Any thoughts? Thank you.

This is not quasar specific, and it would help if you could post your code so we can tell you what is wrong. This should work fine:

<q-input v-model="message"/> 

data () {
  return {
    message: ''
  }
},
methods: {
  messageChanged () {
    console.log(this.message)
  }
},
watch: {
  message () {
    this.messageChanged()
  }
}

My case has been answer at SO. Thank you very much. https://stackoverflow.com/questions/47670499/quasar-framework-method-inside-watcher-is-not-recognized

You issue seems to have been the binding of this due to improper use of arrow functions.
