You can watch props to execute some code upon props changes:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | new Vue({ el: '#app', data: { text: 'Hello' }, components: { 'child' : { template: `<p>{{ myprop }}</p>`, props: ['myprop'], watch: { myprop: function(newVal, oldVal) { // watch it console.log('Prop changed: ', newVal, ' | was: ', oldVal) } } } } }); |
1 2 3 4 5 6 | <script src="https://unpkg.com/vue/dist/vue.js"></script> <div id="app"> <child :myprop="text"></child> <button @click="text = 'Another text'">Change text</button> </div> |
