Please can someone teach me the method to swap two different data on click
For example, we have a data
data() {
return {
data_one: [
{
name: "Simo",
age: "32"
}
],
data_two: [
{
name: "Lisa",
age: "25"
}
],
}
},
then I want to put this data on v-for, and I want to add two buttons to swap from data_one and data_two and display data_one as default.
<button @click="change_to_data_one">Data 1<button>
<button @click="change_to_data_two">Data 2<button>
<li v-for="item in data_one">{{item.name}} - {{item.age}}<li>
๐๐๐๐๐
Try to use computed property:
new Vue({
el: "#demo",
data() {
return {
data_one: [{name: "Simo", age: "32"}],
data_two: [{name: "Lisa", age: "25"}],
selected: "data_one"
}
},
computed: {
showData(){
return this[this.selected]
}
},
methods: {
swap(val) {
this.selected = val
}
}
})<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="demo">
<button @click="swap('data_one')">Data 1</button>
<button @click="swap('data_two')">Data 2</button>
<ul>
<li v-for="(item, i) in showData" :key="i">{{item.name}} - {{item.age}}</li>
</ul>
</div>
