how can get values from va-select when user choose the data?
I use this method to show my data in va-select
<va-select
:label="$t('Unit Code')"
v-model="aircraftData.afta_ProcUnit1"
textBy="name"
searchable
:options="optionsProcUnit1"
:addBtn="true"
placeholder=""
:error="!!afta_ProcUnit1Errors.length"
:error-messages="afta_ProcUnit1Errors"
/>
apiRelatedUnit(postData) {
let self = this;
this.isLoading = true;
SmsApis.relatedUnit.post
.GetRelatedUnit(postData)
.then((xhr) => {
self.isLoading = false;
if (xhr.data.result[0].smsB_RelatedUnit) {
xhr.data.result[0].smsB_RelatedUnit.forEach(function (g, i) {
if (g.runt_Category === "0") {
self.optionsProcUnit2.push({
id: g.runt_unitID,
name: g.runt_unitID + " / " + g.runt_UnitTitle,
tel: g.runt_UnitTel,
});
}
if (g.runt_Category === "2") {
self.optionsProcUnit1.push({
id: g.runt_unitID,
name: g.runt_unitID + " / " + g.runt_UnitTitle,
tel: g.runt_UnitTel,
});
}
});
} else {
self.$swal.fire("Error", xhr.data.result[0].Error, "error");
}
})
.catch(function (error) {
self.isLoading = false;
if (error.message === "Cannot read property 'status' of undefined")
self.$swal.fire("Connect Error", "", "warning");
});
},
And the va-select will show like this one
Test / Sales
Test2 / Dev
Test3 / Bus
and when user click submit, it's will send date and writing in database
pdbt = {
tableA: [
{
afta_ProcUnit1: xxx, //how can get unit code in here???
afta_ProcUnit2: ProcUnit2,
}
]
}
Apis.AircraftAnomaly.post
.EditAircraftAnomaly(pdbt )
.then(function (xhr) {
self.isLoading = false;
if (xhr.data.result[0].Result === "OK") {
self.onEditAnomalyCL();
self.isLoading = true;
}
})
}
how can get value when user choose the options in va-select?
