I am trying to call a parent/root level method on a child component in Vue.js, but I keep getting a message saying TypeError: this.addStatusClass is not a function.
Vue.component('spmodal', {
props: ['addStatusClass'],
created: function() {
this.getEnvironments();
},
methods: {
getEnvironments: function() {
this.addStatusClass('test');
}
}
});
new Vue({
el: '#app',
methods: {
addStatusClass(data) {
console.log(data);
}
}
});
Here is a full JSBIN example: http://jsbin.com/tomorozonu/edit?js,console,output
If I call this.$parent.addStatusClass('test'); it works fine, but based on the Vue.js documentation, this is bad practice and I should be using props which is not working.

To call parent method with component with Vue. js, we can get the parent component's method from the $parent property. to define the child component with Vue. component .
To access child component's data from parent with Vue. js, we can assign a ref to the child component. And then we can access the child component data as a property of the ref. to assign the markdown ref to the markdown component.
The way it works is that you define your data on the parent component and give it a value, then you go to the child component that needs that data and pass the value to a prop attribute so the data becomes a property in the child component. You can use the root component (App.
specifying the prop does nothing on its own, you have to actually pass something to it from the parent - in this case, the function.
<spmodal :add-status-class="addStatusClass"></spmodal>
