Give the child component a ref and use $refs to call a method on the child component directly.
HTML:
1 2 3 4 | <div id="app"> <child-component ref="childComponent"></child-component> <button @click="click">Click</button> </div> |
Javascript:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | var ChildComponent = { template: '<div>{{value}}</div>', data: function () { return { value: 0 }; }, methods: { setValue: function(value) { this.value = value; } } } new Vue({ el: '#app', components: { 'child-component': ChildComponent }, methods: { click: function() { this.$refs.childComponent.setValue(2.0); } } }) |
