I created a select2 wrapper in vue3 with options API everything working fine but the problem is that when getting values from calling API it's not selected the default value in the select2 option. but when I created a static array of objects it does. I don't know why it's working when it comes from the API
Parent Component
Here you can I passed the static options array in options props and my selected value is 2 and it's selected in my Select2
component, but when passed formattedCompanies
it's not which is the same format as the static options array then why is not selected any reason here..?
<template>
<Form @submitted="store()" :processing="submitting">
<div >
<div >
<div >
<label>Company Name</label>
<Select2
:options="options"
v-model="selected"
placeholder="Select Company"
/>
<ValidationError :errors="errors" error-key="name" />
</div>

{ id: 4, text: 'hello4' },
{ id: 5, text: 'hello5' },
],
}
},
mounted() {
this.getAllMedicineCompanies()

let arr = [];
this.companies.forEach(item => {
arr.push({id: item.id, text: item.name})
});

Probably when this Select2 mounted there is no companies. It is empty array after that it will make API call and it it populates options field and clear all options.
Make:
companies : null,
Change it to
<Select2
v-if="formattedCompanies"
:options="formattedCompanies"
v-model="selected"
placeholder="Select Company"
/>
It should be like this:
<template>
<Form @submitted="store()" :processing="submitting">
<div >
<div >
<div >
<label>Company Name</label>
<Select2
v-if="formattedCompanies"
:options="formattedCompanies"
v-model="selected"
placeholder="Select Company"
/>
<ValidationError :errors="errors" error-key="name" />
</div>
</div>
</div>
</Form>
</template>
<script>
import Form from "@/components/Common/Form";
import Select2 from "@/components/Common/Select2";
export default {
components: {
Select2,
Form
},
data() {
return {
selected : 2,
companies : null,
options: [ // static array
{ id: 1, text: 'hello' },
{ id: 2, text: 'hello2' },
{ id: 3, text: 'hello3' },
{ id: 4, text: 'hello4' },
{ id: 5, text: 'hello5' },
],
}
},
mounted() {
this.getAllMedicineCompanies()
},
computed:{
formattedCompanies() {
let arr = [];
this.companies.forEach(item => {
arr.push({id: item.id, text: item.name})
});
return arr;
}
},
methods: {
getAllMedicineCompanies(){
axios.get('/api/get-data?provider=companies')
.then(({ data }) => {
this.companies = data
})
},
}
}
</script>

The problem was that my parent component and Select2
component mounted at the same time that's why my computed
value is not initialized so the selected value is not selected in the option,
problem solved by setTimeOut
function in mounted like this
Select2 Component
<script>
mounted() {
const vm = this;
setTimeout(() => {
$(this.$el)
.select2({ // init select2
data: this.options,
placeholder: this.placeholder,
allowClear: this.allowClear
})
.val(this.modelValue)
.trigger("change")
.on("change", function () { // emit event on change.
vm.$emit("update:modelValue", this.value);
});
}, 500)
},
</script>
