What causes a component to not update when it is connected to an Array using v-model?

Array1 https://i.stack.imgur.com/cY0XR.jpg Array are both connected to the same Array variable using v-model. However, when changes are made to Array1, Array2 does not update. Why is this happening?

Process:

Upon examining the logs, it can be observed that ArrayInput#1 triggered an input event. Despite this, the updated method of ArrayInput#2 was not invoked. What could be causing this?

The source code for reference: http://jsfiddle.net/h313j5sh/3/

Answer №1

To properly handle the passed props value, you should utilize a watcher as shown below:

watch:{
  value: function(val){
     this.text = val.join(',')
  }
}

Additionally, make sure to incorporate v-model in your component markup:

template: '<input type="text" @input="onInputText" placeholder="Enter comma separated array" v-model="text" />',

Check out the live demo here: http://jsfiddle.net/h313j5sh/7/

The Updated block does not work across multiple components, affecting only its own scope within the component.
