My goal is to develop a component with two slots, where the second slot repeats based on the number of items in the first slot. I have successfully implemented this using scoped slots. However, I noticed that when the data in the first slot is updated, the view in the second slot is not automatically refreshed unless an event like a button click triggers a method.
Is there a way to ensure that the second slot updates its view whenever the data changes in the first slot?
Here is an example of what I have:
Jsfiddle: https://jsfiddle.net/89vykm75/1/
new Vue({
el: '#app',
components: {
'repeat-for-each-item': {
data: function() {
return {
items: []
}
},
template: `<div>
<slot name="item" v-for="item in items" :item="item"></slot>
<button @click="addItem()">Add item</button>
<slot name="repeat" v-for="item in items" :item="item"></slot>
</div>
`,
methods: {
addItem() {
this.items.push({});
}
}
}
}
});<div id="app">
<repeat-for-each-item>
<template slot="item" scope="props">
<div>
<input type="text" v-model="props.item.name">
</div>
</template>
<template slot="repeat" scope="props">
<div>
<label>
<span v-if="props.item.name">{{props.item.name}}:</span>
<span v-else>No Name:</span>
</label>
<input type="text">
</div>
</template>
</repeat-for-each-item>
</div>
