Im trying to get the item properties that is being clicked in the option button
This is my code
<select #click="populate" class="form-control" tabindex="12">
<option disabled value="" selected="selected">Select one</option>
<option v-for="(payment, index) in paymentsSelect" #click="pop(payment)"
:key="index"
:value="payment.id">{{ payment.name }}
</option>
</select>
this is my data
selectedPayment: '',
paymentsSelect: [],
these are my methods
pop(payment){
console.log(payment)
},
populate(){
var self = this
this.$http.get(this.$backendUrl + 'subjects/payment_method')
.then(function(response) {
self.paymentsSelect = response.data.data
})
.catch(function() {})
},
No need to add event, just bind the select input to a data property using v-model like :
<select v-model="selectedPayment" class="form-control" tabindex="12">
<option disabled value="" selected="selected">Select one</option>
<option
v-for="(payment, index) in paymentsSelect"
:key="index"
:value="payment">
{{ payment.name }}
</option>
</select>
selectedPayment changes when you select an option then use it in your script like this.selectedPayment
In the below code I have a value and that is an object how to can I push to the exist array.
methods: {
onChange(event) {
this.newItems.push(event.target.value);
console.log(event.target.value);
}
}
and my blade is:
<select #change='onChange($event)' class="form-control">
<option value="" selected disabled>Choose</option>
<option v-for='item,key in items' :value="item">#{{ item.name }}</option>
</select>
I would suggest using v-model on the select to detect which is currently selected.
<div id="app">
<select #change="onChange" class="form-control" v-model="selected">
<option value="" selected disabled>Choose</option>
<option v-for='item,key in items' :value="item">#{{ item.name }}
</option>
</select>
<p v-for="newItem in newItems">
{{newItem}}
</p>
</div>
and then push this.selected in your onChange method instead:
this.newItems.push(this.selected)
Hope this helps.
Working fiddle of your code with some small modifications:
https://jsfiddle.net/MapletoneMartin/e4oth98p/7/
My component vue is like this :
<template>
<select class="form-control" v-model="selected" :required #change="changeLocation">
<option :selected>Choose Province</option>
<option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>
</select>
</template>
I use this : <option :selected>Choose Province</option> to selected
But whene executed, on the gulp watch exist error
The error like this :
ERROR in
./~/vue-loader/lib/template-compiler.js?id=data-v-53777228!./~/vue-load
er/lib/selector.js?type=template&index=0!./resources/assets/js/components/bootst
rap/LocationBsSelect.vue Module build failed: SyntaxError: Unexpected
token (28:4)
Seems my step is wrong
How can I solve it?
Handling the errors
You are binding properties to nothing. :required in
<select class="form-control" v-model="selected" :required #change="changeLocation">
and :selected in
<option :selected>Choose Province</option>
If you set the code like so, your errors should be gone:
<template>
<select class="form-control" v-model="selected" :required #change="changeLocation">
<option>Choose Province</option>
<option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>
</select>
</template>
Getting the select tags to have a default value
you would now need to have a data property called selected so that v-model works. So,
{
data () {
return {
selected: "Choose Province"
}
}
}
If that seems like too much work, you can also do it like:
<template>
<select class="form-control" :required="true" #change="changeLocation">
<option :selected="true">Choose Province</option>
<option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>
</select>
</template>
When to use which method?
You can use the v-model approach if your default value depends on some data property.
You can go for the second method if your default selected value happens to be the first option.
You can also handle it programmatically by doing so:
<select class="form-control" :required="true">
<option
v-for="option in options"
v-bind:value="option.id"
:selected="option == '<the default value you want>'"
>{{ option }}</option>
</select>
The simplest answer is to set the selected option to true or false.
<option :selected="selectedDay === 1" value="1">1</option>
Where the data object is:
data() {
return {
selectedDay: '1',
// [1, 2, 3, ..., 31]
days: Array.from({ length: 31 }, (v, i) => i).slice(1)
}
}
This is an example to set the selected month day:
<select v-model="selectedDay" style="width:10%;">
<option v-for="day in days" :selected="selectedDay === day">{{ day }}</option>
</select>
On your data set:
{
data() {
selectedDay: 1,
// [1, 2, 3, ..., 31]
days: Array.from({ length: 31 }, (v, i) => i).slice(1)
},
mounted () {
let selectedDay = new Date();
this.selectedDay = selectedDay.getDate(); // Sets selectedDay to the today's number of the month
}
}
<select v-model="challan.warehouse_id">
<option value="">Select Warehouse</option>
<option v-for="warehouse in warehouses" v-bind:value="warehouse.id" >
{{ warehouse.name }}
</option>
Here "challan.warehouse_id" come from "challan" object you get from:
editChallan: function() {
let that = this;
axios.post('/api/challan_list/get_challan_data', {
challan_id: that.challan_id
})
.then(function (response) {
that.challan = response.data;
})
.catch(function (error) {
that.errors = error;
});
}
You simply need to remove v-bind (:) from selected and required attributes.
Like this :-
<template>
<select class="form-control" v-model="selected" required #change="changeLocation">
<option selected>Choose Province</option>
<option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>
</select>
</template>
You are not binding anything to the vue instance through these attributes thats why it is giving error.
My code for reactive multiselect
data() {
return {
article: {title: 'aaaaa', 'categoriesIds': [1,3], ...},
selectCategories: {1: 'xxx', 2: 'www', 3: 'yyy', 4: 'zzz'},
}
},
template
<div class="form-group">
<label for="content">Categories</label>
<select name="categories"
v-model="article.categoriesIds"
id="categories"
multiple
class="form-control col-md-5"
size="6">
<option v-for="(category, key) in selectCategories"
:key="key"
v-bind:value="key">{{category}}</option>
</select>
</div>
Selected items are binded to the article.categoriesIds array.
Another way, which I often find more reliable, is you could add a directive to your app.js or wherever you are initiating your VueJS, eg:
Vue.directive('attr', (el, binding) => {
if (binding.value === true) binding.value = ''
if (binding.value === '' || binding.value) {
el.setAttribute(binding.arg, binding.value)
}
})
You can then utilise v-attr to set an attribute, eg:
<option value="Western Australia" v-attr:selected="form.state == 'Western Australia'">Western Australia</option>
So as I understand the main goal is to set "Choose Province" as the default. I tried other options but the simple one worked for me the best:
<template>
<select class="form-control" v-model="selected" :required #change="changeLocation">
<option>Choose Province</option> # just an option with no selected or assigned v-model
<option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>
</select>
</template>
I would like to have a dynamic select option values bind to select dropdown.
<div ng-repeat="condition in conditions">
<div class="form-group">
<select ng-model="condition.Description" class="form-control">
<option value="">- Select -</option>
<option ng-value="{{age.Description}}" ng-repeat="age in ageConditions">{{age.Description}}</option>
</select>
</div>
</div>
I like
age in ageConditions
to be dynamic. I also tried ng-options="dynamicOptions" but it always bind to the same list.
I want to achieve this with ng-repeat.
Repeat 1:
<select ng-model="condition.Description" class="form-control">
<option value="">- Select -</option>
<option ng-value="ageCondition1">ageCondition1</option>
<option ng-value="ageCondition2">ageCondition2</option>
</select>
Repeat 2:
<select ng-model="condition.Description" class="form-control">
<option value="">- Select -</option>
<option ng-value="yearsCondition1">yearsCondition1</option>
<option ng-value="yearsCondition2">yearsCondition2</option>
</select>
As shown i want the option in select to be dynamic in ng-repeat.
Any idea?
<select ng-model="condition.Description" class="form-control">
<option value="">- Select -</option>
<option value="getValue(age, $parent.$index)" ng-repeat="age in ageConditions"> getText(age, $parent.index)</option>
</select>
Please note that $parent.$index is used.
the dynamic nature van be achieved used functions which return the value based in $index.
$scope.getValue = function(age, index) {
if(index === 1) return age.Desciption else age.years;
}
$scope.getText = function(age, index) {
if(index === 1) return age.Desciption else age.years;
}
hope this helps
Solved this by creating a directive that created a new scope for select.
I have some problem with my selects. Here is code:
<select ng-model="car" ng-options="car.name for car in cars track by car.id" class="form-control">
<option value="">Choose model name</option>
</select>
<br />
<select ng-options="model.name for model in car.models track by model.id" ng-model="model" class="form-control">
<option value="">Choose car</option>
</select>
I want that when i visit this page that the two selects have default values. For example in first select - "BMW" and in second - "528I" at the same time. I'm trying to do this solution:
<select ng-model="car" ng-init="car.id = 1" ng-options="car.name for car in cars track by car.id" class="form-control">
<option value="">Choose model name</option>
</select>
<br />
<select ng-init="model.id = 5" ng-options="model.name for model in car.models track by model.id" ng-model="model" class="form-control">
<option value="">Choose car</option>
</select>
But it work only for the fisrt select. (And when i choose the name in first select with name with id = 1, the second select to switch to the model with id = 5;)
I don't know how to reailze default values in two selects at the same time.
Have you any ideas?
Here is plunker
You could just use ng-init, like this:
<select ng-init="car=cars[0]" ng-model="car" ng-options="car.name for car in cars" class="form-control">
<option value="">Choose model name</option>
</select>
<br />
<select ng-init="model=car.models[0]" ng-options="model.name for model in car.modelsd" ng-model="model" class="form-control">
<option value="">Choose car</option>
</select>
UPDATE
The syntax of your select was a bit off, you actually don't need to use track by unless you are grouping the values of your select, which you are not. I think that what you actually wanted was to have the model bound to the id of the 'car' rather than having the model bound to the car itself. If that's what you want you could do it like this:
<select ng-init="car=1" ng-model="car" ng-options="car.id as car.name for car in cars" class="form-control">
<option value="">Choose model name</option>
</select>
But then you would have to do something very awkward in order to render the second select with the models of the car, because in that case your variable car would be an int (the id of the car), not the 'car' object, so you would have to do something like this:
<select ng-init="model=5" ng-model="model" ng-options="model.id as model.name for model in ((cars | filter:{id:car})[0].models)" class="form-control">
<option value="">Choose car</option>
</select>
Which is just as awkward as it looks, but if that's what you want... well, here you have an example:
Working example
A better idea in my opinion would be to have the models pointing to the objects, and if you want to initialize the selects through the id, you could do this in the ng-init :
<select ng-init="car=(cars|filter:{id:1})[0]" ng-model="car" ng-options="car.name for car in cars" class="form-control">
<option value="">Choose model name</option>
</select>
<br />
<select ng-init="model=(car.models|filter:{id:5})[0]" ng-options="model.name for model in car.models" ng-model="model" class="form-control">
<option value="">Choose car</option>
</select>
Working Example
You may use ng-model attribute in your controller and assign a default variable like
<div ng-controller="MyController" >
<form>
<select ng-model="myForm.car">
<option value="nissan">Nissan</option>
<option value="toyota">Toyota</option>
<option value="fiat">Fiat</option>
</select>
</form>
<div>
{{myForm.car}}
</div>
</div>
<script>
angular.module("myapp", [])
.controller("MyController", function($scope) {
$scope.myForm = {};
$scope.myForm.car = "nissan";
} );
</script>
