I am facing a tricky challenge in Vue.js - I need to create two select fields. The first one should be used to select between fruits and vegetables, and based on that selection, the second field should dynamically display the corresponding list of items.
I have searched online for similar solutions, but I am struggling with how to set the default selected item in the second select field when switching between fruits and vegetables.
My goal is to have the first item in the second select field automatically selected whenever I switch between fruits and vegetables in the first select field.
Please take a look at my code here: https://jsfiddle.net/aj6g87dh/1/
new Vue({
el: '#test',
data: {
category: 'fruits',
list: '',
optionsData: {
fruits: [
{ text: 'Orange', value: 'orange' },
{ text: 'Banane', value: 'banana' },
],
vegetables: [
{ text: 'Brocolis', value: 'brocolis' },
{ text: 'Radish', value: 'radish' },
]
}
},
computed: {
options: function() {
let options = ''
switch (this.category) {
case 'fruits':
options = this.optionsData.fruits
break;
case 'vegetables':
options = this.optionsData.vegetables
break;
default:
options = this.optionsData.fruits
}
return options
}
},
methods: {
onChange: function() {
this.options = this.options
}
}
})<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.0.5/vue.js"></script>
<div id="test">
<select v-model="category" v-on:change="onChange" id="select1">
<option value="fruits">Fruits</option>
<option value="vegetables">Vegetables</option>
</select>
<select id="select2" v-model="list">
<option v-for="option in options" v-bind:value="option.value"> {{ option.text }} </option>
</select>
<span>{{ }}</span>
</div>
