I got a child-component inside a v-if block:
<div v-if="mappingData && mappingData.length && !loading">
<div v-for="element in mappingData" :key="element.attribute" >
<PkSelect :preselectIndex="[element.value]"
:options="element.select_options" v-model:optionIndexModel="element.value"></PkSelect>
</div>
</div>
Now to get the loading value plus the element.select_option values I got a recursive method:
const recursiveFuzzyFill = () => {
let awaitme = new Promise((resolve, reject) => {
try {
if (mappingData.value[loopIndex] && fuse.search(mappingData.value[loopIndex].label).length) {
var refIndex = fuse.search(mappingData.value[loopIndex].label)[0].refIndex;
mappingData.value[loopIndex].value = refIndex;
console.log("Value:", mappingData.value[loopIndex].value);
resolve();
} else {
resolve();
}
} catch (error) {
reject();
loopIndex = 0;
return;
}
});
awaitme.then(() => {
if (loopIndex === (mappingData.value.length - 1)) {
setTimeout(() => {
loopIndex = 0;
loading.value = false;
console.log("Loading:", loading.value);
}, 5000);
return;
} else {
loopIndex++;
recursiveFuzzyFill();
}
});
}
The loading ends 5 seconds after the data is determined. Still logging the values looks like this:
Value: 16
PkSelect.vue:709 Preselect Index: 16
PkSelect.vue:709 Preselect Index: null
PkSelect.vue:709 Preselect Index: null
PkSelect.vue:709 Preselect Index: null
PkSelect.vue:709 Preselect Index: null
PkSelect.vue:709 Preselect Index: null
PkSelect.vue:709 Preselect Index: null
ConfigMapping.vue:184 Value: 27
ConfigMapping.vue:184 Value: 13
ConfigMapping.vue:184 Value: 18
ConfigMapping.vue:201 Loading: false
The select-component is receiving data even if the condition for v-if isn't fulfilled. How could this happen?

what exactly is happening is when i select the delivery service onChangeService i'm setting the next dropdown i.e. carrier's list.Also i'm setting the selected carrier as per the service.But all the time value is getting set correctly in {this.state.selectedCarrierName} but still i can show its label only.lists contain label an value pair
async onChangeService(value) {
//{ ...this.props.deliveryOptionsValue, selected: value.value === value }
this.setState({ newCarrierList: [], selectedCarrierName: '', selectedCararierName: '' });
const priceDeliveryService = this.props.orderDetailsDTO.priceDeliveryServiceDTOs;
console.log("carriers", JSON.stringify(this.props.carriers));
var newList = [];
var carrier = '';
await priceDeliveryService.forEach(m => {
console.log("compare", m.serviceId === value.id);
if (m.serviceId === value.id) {
console.log("carrier", JSON.stringify(this.props.carriers));
let l = this.props.orderDetailsDTO.carriers.filter(n => n.id === m.carrierId);
console.log("l", l);
if (l !== undefined) {
// / orderList: [...this.state.orderList, ...content]
// this.setState({ newCarrierList: [...this.state.newCarrierList, ...l[0]] });
newList.push(l[0]);
console.log("defa", newList);
if (m.defaultCarrierService) {
this.setState({ selectedCarrier: l[0], selectedCarrierName: l[0].name });
carrier = l[0].name;
} else {
this.setState({ selectedCarrier: newList[0], selectedCarrierName: newList[0].name });
carrier = newList[0].name;
}
}
}
});
const list = newList.map(item => ({
label: item.name,
value: item
}));
this.setState({ newCarrierListValue: list, newCarrierList: newList })
console.log("newCarrierListValue", list);
console.log("newCarrierList", newList);
// console.log("carrier service", p.carrierName, value.id);
const carrierServices = this.props.orderDetailsDTO.carrierServiceDTO;
console.log(carrierServices.length);
const pi = await this.setCarrierService(carrierServices, value, carrier);
// let pi;
// for (let i = 0; i < carrierServices.length; i++) {
// console.log("if", carrierServices[i].cdlServiceId == value.id, carrierServices[i].carrierName === carrier)

// pi = carrierServices[i];
// console.log(pi);

The select box not showing sometimes the first color and sometimes not showing the first color.
How can i make it to show all the item in the select box?
I'm not getting for some reason all the promises
You can see the issue in the picture
Please help me to fix this issue i'm new to vue js
My code:
data() {
return {
propertiesTree: []
}
}
getPropertyGroups(objectId: number): void {
if (this.$data.currentObjectId === objectId)
return;
let component: any = this;
this.$data.currentObjectId = objectId;
component.showLoader();
this.$store.dispatch('properties/getPropertyGroups', objectId)
.then(({ data, status }: { data: string | Array<propertiesInterfaces.PropertyGroupDto>, status: number }) => {
// console.log(data, "data");
// console.log(status, "status")
if (status === 500) {
this.$message({
message: data as string,
type: "error"
});
}
else {
let anyData = data as any;
anyData.map(item => {
item.properties.map(prop => {
if(prop.type.toString() === 'dictionary'){
prop.dictionaryList = [];
prop.color = '';
this.getWholeDictionaryList(prop.dictionaryId.value, prop)
}
});
});
}
component.hideLoader();
});
},
getWholeDictionaryList(dictionaryId: number, prop: any){
this.$store.dispatch('dictionaries/getWholeDictionaryList', dictionaryId).then(
({ data, status }: { data: Array<any> |string , status: number }) => {
if (status === 500) {
this.$message({
message: data as string,
type: "error"
});
} else {
const arrData = data as Array<any>;
arrData.map((item,index) => {
prop.dictionaryList = [];
prop.dictionaryList = data;
this.getDictionaryItemColor(item.id.value, data, index, prop);
});
}
});
},
getDictionaryItemColor(dictionaryItemId:number, dictionaryList: Array<any>, index:number, current){
this.$store.dispatch('patterns/getDictionaryItemColor', dictionaryItemId).then((data: any, status: number) => {
if (status === 500) {
this.$message({
message: data as string,
type: "error"
});
} else{
debugger
if(current.dictionaryItemId.value === data.data.sceneObjectId)
current.color = data.data.colorString;
dictionaryList[index].color = data.data.colorString ? data.data.colorString: '#FFFFFF';
}
});
},
Html code of the select box
<el-select v-model="data.color" placeholder="Select">
<el-option
v-for="item in data.dictionaryList"
:key="item.name"
:label="item.color"
:value="item.color">
</el-option>
</el-select>
I did return to dispatch
let dispatch = this.getWholeDictionaryList(prop.dictionaryId.value, prop)
let promiseArr = [];
promiseArr.push(dispatch);
after the map closing tag i did
Promise.all(promisArr).then( () => {
debugger
this.$data.propertiesTree = anyData;
});
And I've got it solved
const interval = setInterval(() => {
fire.database().ref().child(getpath())
.once("value",
(snapshot) => {
let item = snapshot.val()
console.log(item)
if (item !== null) {
let array = [];
Object.
keys(item)
.forEach(i => array.push(item[i]));
setCard1(array);
}
console.log(item, "item")
if (item !== null) {
itemlen = 7 //length of object I get from valid result
//stop polling for results
console.log(itemlen, "should clear")
}
else {
console.log("polling")
}
})
}, 1000)
console.log("comingout")
if (itemlen !== 0) {
console.log("goingIn")
clearInterval(interval);
}
}, [prefVar]);
expected clearinterval to stop the setinterval function but it is running continuosly and not stopping
itemlen is getting non zero values.Is there a better way of implementing this ?
I want stop useEffect once I get valid value from db.My code inside the for setinterval selects a random path and retrieve that path only problem is that sometimes the path is empty,thus using setInterval
I would create two state items, one which keeps the interval and the other which stores itemlen, and would use another useEffect to listen on changes to itemlen, and when it is not 0, the interval should clear. Also, I would check if there is another interval running before you start another one.
const [itemlen, setItemlen] = useState(0);
const [pollingInterval, setPollingInterval] = useState(null);
useEffect(() => {
if (pollingInterval === null) {
setPollingInterval(setInterval(() => {
fire.database().ref().child(getpath())
.once("value",
(snapshot) => {
let item = snapshot.val()
console.log(item)
if (item !== null) {
let array = [];
Object.
keys(item)
.forEach(i => array.push(item[i]));
setCard1(array);
}
console.log(item, "item")
if (item !== null) {
setItemlen(7);
console.log("should clear")
} else {
console.log("polling")
}
})
}, 1000));
}
}, [prefVar]);
useEffect(() => {
if (itemlen !== 0 && pollingInterval !== null) {
clearInterval(pollingInterval);
setPollingInterval(null);
}
}, [itemlen])
I have a table with an input column. This input column will have value if it has been saved in ddbb before.
If this value changes, handled with an event '#blur', I show a modal to confirm the change.
My problem is that if you want to keep the old value it will always change...
I tried to change this value with javascript, but it doesn't work... Any suggestions?
This is my code:
<b-tbody>
<b-tr
v-for="(driver, index) in drivers"
:key="driver.clientId">
<b-td
data-label="Client"
:title="driver.clientName">{{ driver.clientName }}</b-td>
<b-td data-label="Numerator">
<b-input
:id="'numeratorDriver_'+index"
class="driver-numerator text-right"
type="text"
:value="(driver.driverNumerator === undefined) ? 0 : $utils.formatNumber(driver.driverNumerator)"
#blur="calculatePricingDriver($event, index)" /></b-td>
<b-td
class="text-right"
data-label="Pricing"
:title="driver.pricingDriver"><span>{{ driver.pricingDriver }}</span></b-td>
</b-tr>
</b-tbody>
<script>
function calculatePricingCustomDriver (event, index) {
let lastValue = this.drivers[index].driverNumerator
if (this.$store.getters.price !== undefined) {
let title = 'Modify numerator'
let message = 'If you modify numerator driver, the calculated pricing will be deleted'
this.$bvModal.msgBoxConfirm(message, {
title: title,
size: 'sm',
buttonSize: 'sm',
okTitle: 'Yes',
okVariant: 'primary',
cancelTitle: 'No',
cancelVariant: 'primary',
hideHeaderClose: false,
centered: true
})
.then(confirmed => {
if (confirmed) {
this.$http.get('delete-price', { params: { id: this.$store.getters.id } })
.then((response) => {
if (response.status === this.$constants.RESPONSE_STATUS_OK) {
this.price = ''
let newNumerator = event.target.value
this.drivers[index].driverNumerator = Number(newNumerator)
let sumTotal = _.sumBy(this.drivers, 'driverNumerator')
for (let i = 0; i < this.drivers.length; i++) {
this.drivers[i].pricingDriver = (this.drivers[i].driverNumerator / sumTotal).toFixed(2)
}
} else {
this.drivers[index].driverNumerator = lastValue
// this is that I want change because it doesn't work fine
document.getElementById('numeratorDriver_' + index).value = lastValue
}
})
} else {
this.drivers[index].driverNumerator = lastValue
document.getElementById('numeratorDriver_' + index).value = lastValue
}
})
.catch(() => {
/* Reset the value in case of an error */
this.$utils.showModalError()
})
} else {
let newNumerator = event.target.value
this.drivers[index].driverNumerator = Number(newNumerator)
let sumTotal = _.sumBy(this.drivers, 'driverNumerator')
for (let i = 0; i < this.drivers.length; i++) {
this.drivers[i].pricingDriver = (this.drivers[i].driverNumerator / sumTotal).toFixed(2)
}
}
}
</script>
how is calculatePricingCustomDriver being loaded into your Vue component? For it to be called like that from #blur you would need to define it as a method:
<template>
<!-- your table-->
</template>
<script>
export default {
name: "MyComponent",
methods : {
calculatePricingCustomDriver () {
// your code
}
}
}
</script>
Or it could be installed as a global mixin
I have a simple form to update a password with 3 inputs (old_password, new_password and new_password_confirmation).
After the submit, if it is updated successfully, the inputs are cleaned. The problem is that after this, the input errors are showed even when the conditional is false.
This is one of the inputs:
<input type="password" v-model="old_password">
<small class="text-danger" v-if="errors.old_password != ''">{{errors.old_password}}</small>
The logic:
<script>
export default {
data() {
return {
old_password: '',
errors: []
}
},
watch: {
old_password(value) {
this.old_password = value
if(value.length < 3) {
this.errors.old_password = 'Debes ingresar al menos 4 caracteres'
} else {
this.errors.old_password = ''
}
}
},
methods: {
updatePassword() {
this.$store.dispatch('updatePassword', data)
.then(response => {
this.old_password = ''
this.errors.old_password = ''
})
.catch(error => {
})
}
}
}
</script>
Because once input becomes empty your condition value.length < 3 is true and error will be shown
Simply add to your condition this one && value.length > 0
So the final code will look like
if(value.length < 3 && value.length > 0) {
this.errors.old_password = 'Debes ingresar al menos 4 caracteres'
} else {
this.errors.old_password = ''
}
Also, errors should be an object instead of an array - errors: {}
