vuejs semantic ui - drop down not displaying on arrow click - vuejs2

I'm faced with an issue where my semantic drop down in my vue project won't activate when clicking on the arrow icon but works when I click on the rest of the element. The drop down also works when I set the dropdown to activate on hover, but just not on click. Solutions I've tried:
tested if the dynamic id are at fault
tested if the back ticks are confusing things
placed the values directly into the semantic drop down
Aside from the dropdown not activating, the code below works as intended and brings back the selected value to the parent component and can be displayed.
Dropdown.vue:
<template>
<div class="ui selection dropdown" :id="`drop_${dropDownId}`">
<input type="hidden" name="gender" v-model="selected">
<i class="dropdown icon"></i>
<div class="default text">Gender</div>
<div class="menu">
<div class="item" v-for="option in options" v-bind:data-value="option.value">
{{ option.text }}
</div>
</div>
</div>
</template>
<script>
export default {
data: function () {
return {
selected: {}
}
},
watch: {
selected: function (){
this.$emit("dropDownChanged", this.selected)
}
},
props: {
options: Array, //[{text, value}]
dropDownId: String
},
mounted () {
let vm = this;
$(`#drop_${vm.dropDownId}`).dropdown({
onChange: function (value, text, $selectedItem) {
vm.selected = value;
},
forceSelection: false,
selectOnKeydown: false,
showOnFocus: false,
on: "click"
});
}
}
</script>
The component usage:
<vue-drop-down :options="dropDownOptions" dropDownId="drop1" #dropDownChanged="dropDownSelectedValue = $event"></vue-drop-down>
The data in the parent:
dropDownOptions: [
{ text: 'One', value: 'A' },
{ text: 'Two', value: 'B' },
{ text: 'Three', value: 'C' }
],
dropDownSelectedValue: ""
Here is a fiddle of the above but simplified to use a flatter project. However the problem doesn't reproduce :(

I'm not sure what is causing your issue (as the examples on the Semantic Ui website look similar), but there is a workaround. For you arrow icon:
<i #click="toggleDropDownVisibility" class="dropdown icon"></i>
And then in the methods section of your Vue component:
methods: {
toggleDropDownVisibility () {
$(`#drop_${this.dropDownId}`)
.dropdown('toggle');
}
},

How to validate radio buttons in a b-form-radio-group in vuejs

I have a b-form-radio-group of radio buttons, how can I validate them as one of them must be checked?
Here is a div of b-form-radio-group inside the b-modal
<b-modal id="manageQuantity" title="Manage Quantity" #ok="updateQuantity">
<div class="radio-button">
<b-form-group
id="quantityOption"
label-cols-sm="3"
label="Option :"
label-for="input-horizontal"
>
<b-form-radio-group
id="quantityOption"
class="individual-button"
buttons
button-variant="outline-secondary"
v-model="form.quantityOption"
:options="quantityOptions"
></b-form-radio-group>
</b-form-group>
</div>
</b-modal>
When I click "OK" button the b-modal should warn me if I did not select any of the radio button.
You need to add state property. You also can use the b-form-invalid-feedback b-form-valid-feedback slots for the messages:
<b-form-radio-group
id="quantityOption"
class="individual-button"
buttons
button-variant="outline-secondary"
v-model="form.quantityOption"
:options="quantityOptions"
:state="state"
>
<b-form-invalid-feedback :state="state">Please select one</b-form-invalid-feedback>
<b-form-valid-feedback :state="state">Thank you</b-form-valid-feedback>
</b-form-radio-group>
....
data(){
return{
form:{
quantityOption: null
}
}
}
...
computed: {
state() {
return Boolean(this.form.quantityOption)
}
}
...
You could find more in the documentation: https://bootstrap-vue.js.org/docs/components/form-radio/#contextual-state-with-feedback-example
In your updateQuantity method you can check if your quantityOptionis set or not.
You could also implement Andriy's answer for a more visual representation, but you still need the check in the event to make sure it's set or not.
<div>
<b-btn v-b-modal.modal>Open Modal</b-btn>
<b-modal id="modal" #ok="updateQuantity">
<b-form-radio-group
buttons
button-variant="outline-secondary"
v-model="form.quantityOption"
:options="quantityOptions"
></b-form-radio-group>
</b-modal>
</div>
<script>
data() {
return {
form: { quantityOption: null },
quantityOptions: [
{value: 1, text: '1' },
{value: 2, text: '2' },
{value: 3, text: '3' }
]
}
},
methods: {
updateQuantity(event) {
if(!this.form.quantityOption){
alert('Please select one of the options first')
event.preventDefault()
}
}
}
</script>

Bootstrap Select not working inside Bootstrap Vue Modal

I am using Bootstrap Vue with Bootstrap select and the select works perfectly outside the modal
It doesnt open at all inside the modal. Live code is HERE

:selected="option.selected">
{{ option.title }}
</option>
</select>
</script>
The dropdown select wont open at all. Any help is appreciated
I had the same problem. After trying various ways, I found a solution.
When you wanna show modals, don not use v-b-modal directive.
Create a method, using this.$bvModal.show() to show modals.
And then you should use this.$nextTick([callback]) .
Final, use javascript to call bootstrap-select in the callback method
The method will be like
Html
<b-btn #click="ShowModal">Launch demo modal</b-btn>
Js
...
ShowModal() {
this.$bvModal.show('modal1');
this.$nextTick(()=>{
$('select').selectpicker();
})
},
...
ps:Sorry for my poor English and hope you can understand what I mean

How to use query parameter in Vue search box?

I have a page with a search box on it using Vue. What I want to do is this: when a user comes from another page with a parameter in the URL (e.g., myurl.com/?windows), I capture the parameter and populate the search field to run the search on that string when the page loads. If there's no parameter, nothing happens.
I'm capturing the string from the URL with JavaScript, but don't see how to get it in the input to run the search.... I created a method but don't see how to apply it.
<div id="app">
<input type="text" v-model="search" placeholder="Search Articles" />
<div v-for="article in filteredArticles" v-bind:key="article.id" class="container-fluid to-edges section1">
<div class="row">
<div class="col-md-4 col-sm-12 section0">
<div class="section0">
<a v-bind:href="article.url" v-bind:title="toUppercase(article.title)">
<img class="resp-img expand section0"
v-bind:src="article.src"
v-bind:alt="article.alt"/>
</a>
</div>
<div>
<h3 class="title-sec">{{ article.title }}</h3>
<p>{{ article.description }}</p>
</div>
</div>
</div>
</div>
</div>
<script type="text/javascript">
var pgURL = window.location.href;
var newURL = pgURL.split("?")[1];
console.log(newURL);
</script>
// Filters
Vue.filter('to-uppercase', function(value){
return value.toUpperCase();
});
new Vue({
el: "#app",
data: {
articles: [
{ id: 1, title: 'Trend Alert: Black Windows', category: 'Windows', description: 'Timeless, elegant, and universally flattering, black is an excellent color to add to any wardrobe – or any window. Get in the black with this chic design trend.', src: 'http://i1.adis.ws/i/stock/Trending_Polaroid_Black_Windows_2018_1?$trending-mobile$', url: '/{StorefrontContextRoot}/s/trending/trend-alert-black-windows', alt: 'Pantone Colors image' },
{ id: 2, title: 'Benefits of a Pass-Through Window', category: 'Windows', description: 'Whether you’re adding a pass-through window in order to enjoy an al fresco aperitif or for easier access to appetizers in the kitchen, we’re big fans of bringing the outdoors in.', src: 'http://i1.adis.ws/i/stock/polaroid_benefitsofapassthroughwindow655x536?$trending-mobile$', url: '/{StorefrontContextRoot}/s/trending/kitchen-pass-through-bar-window', alt: 'Benefits of a Pass-Through Window image' }, etc....
],
search: ''
},
methods: {
toUppercase: function(title){
return title.toUpperCase();
},
urlSearch: function(newURL) {
if (newURL) {
return this.search = newURL;
}
}
},
computed: {
filteredArticles: function() {
// returning updated array based on search term
return this.articles.filter((article) => {
return article.category.match(new RegExp(this.search, "i"));
});
}
}
})
You can call the urlSearch method during the mounted hook:
mounted() {
this.urlSearch(newURL)
},
methods: {
urlSearch(url) {
return this.search = url
}
},

Vue.js - Select / dropdown selected item vm binding is not working (bootstrap-vue)

I'm trying to create a simple vue that binds the selected item from a select/dropdown to a property in the vm.
I haven't been able to find a clear and simple example of how this is down when using an options collection that is also in the view model.
<template>
<div>
<h1>Select box</h1>
<b-dropdown id="ddCommodity"
name="ddCommodity"
v-model="ddTestVm.ddTestSelectedOption"
text="Select Item"
variant="primary"
class="m-md-2" v-on:change="changeItem">
<b-dropdown-item disabled value="0">Select an Item</b-dropdown-item>
<b-dropdown-item v-for="option in ddTestVm.options":selected="option.value == 'LME/ST_TNI_ALL'":value="option.value">{{option.text}}</b-dropdown-item>
</b-dropdown> <span>Selected: {{ ddTestVm.ddTestSelectedOption }}</span>
</div>
</template>
<script>
export default {
components: {
},
data() {
return {
someOtherProperty: null,
ddTestVm: {
originalValue: [],
ddTestSelectedOption: "Value1",
disabled: false,
readonly: false,
visible: true,
color: "",
options: [
{
"value": "Value1",
"text": "Value1Text"
},
{
"value": "Value2",
"text": "Value2Text"
},
{
"value": "Value3",
"text": "Value3Text"
}
]
}
}
},
methods: {
changeItem: async function () {
//grab some remote data
try {
let response = await this.$http.get('https://www.example.com/api/' + this.ddTestVm.ddTestSelectedOption + '.json');
console.log(response.data);
this.someOtherProperty = response.data;
} catch (error) {
console.log(error)
}
}
},
watch: {
},
async created() {
}
}
</script>
<style>
</style>
Regardless of what i've tried i cannot get the selected value in the dropdown to change the ddTestSelectedOption property of the vm.
Could anyone assist on this issue?
Thanks.
b-dropdown in bootstrap-vue does not support v-model. As the documentation states:
Dropdowns are toggleable, contextual overlays for displaying lists of
links and actions in a dropdown menu format.
In other words, b-dropdown is essentially a UI component for displaying a menu or similar set of options.
I expect what you want is b-form-select.
That said, you could add a click handler to the options that sets the value.
<b-dropdown-item v-for="option in ddTestVm.options"
:key="option.value"
:value="option.value"
#click="ddTestVm.ddTestSelectedOption = option.value">
Here is a working example.
I thing you need b-form-select
<template>
<div>
<b-form-select v-model="selected" :options="options"></b-form-select>
<b-form-select v-model="selected" :options="options" size="sm" class="mt-3"></b-form-select>
<div class="mt-3">Selected: <strong>{{ selected }}</strong></div>
</div>
</template>
<script>
export default {
data() {
return {
selected: null,
options: [
{ value: null, text: 'Please select an option' },
{ value: 'a', text: 'This is First option' },
{ value: 'b', text: 'Selected Option' },
{ value: { C: '3PO' }, text: 'This is an option with object value' },
{ value: 'd', text: 'This one is disabled', disabled: true }
]
}
}
}
</script>
Only b-form-select can achieve the selected value behaviour.
Non-Selected Value Preview:
Selected Value Preview:
Sample Code:
<template>
<div>
<b-form-select v-model="selected" :options="options"></b-form-select>
</div>
</template>
<script>
export default {
data() {
return {
selected: null,
options: [
{ value: 1, text: 'Please select an option' },
{ value: 2, text: 'This is First option' },
{ value: 3, text: 'Selected Option' }
]
}
}
}
</script>
Wanted to leave a comment, but code example looks pale there :)
Yes, b-dropdown does not properly support Vue model, but it doesn't have to.
For those still interested in exactly dropdown (f.e. because it looks fancier), consider:
<b-dropdown :text="$i18n.locale" >
<b-dropdown-item v-for="(lang, i) in $i18n.availableLocales" :key="`Lang${i}`" :value="lang" v-on:click="$i18n.locale = lang;" >{{lang}}</b-dropdown-item>
</b-dropdown>
Slecifically v-on:click, which can handle the model value change for you.

Nested Components and Proper Wrapping Techniques in VueJS

I'm trying to put Bootstrap Select2 in a Vue wrapper. Somehow, my code works. But It doesn't seem proper to me.
I found a reference in here https://v2.vuejs.org/v2/examples/select2.html
In the VueJS website example, the el is empty. I didn't stick to this concept where in the new Vue part, they included a template because my el have sidebars and other stuffs also. What I did was I added a
<admin-access></admin-access>
to a section in the HTML.
I think I made my component nested which I'm skeptical if it is proper in VueJS.
Is there a better way to code this?
Templates
<template id="select2-template">
<select>
<slot></slot>
</select>
</template>
<template id="admin-access">
<div>
<transition name="access" enter-active-class="animated slideInRight" leave-active-class="animated slideOutRight" appear>
<div class="box box-solid box-primary" v-if="admin" key="create">
<div class="box-header with-border">
<i class="fa fa-text-width"></i>
<h3 class="box-title">Create Admin</h3>
</div>
<div class="box-body">
<form action="" class="search-form">
<div class="form-group">
<label for="search_user_admin">Search User</label>
<select2 name="search_user_admin" id="search-user-admin" class="form-control select2" :options="options" v-model="selected">
<option disabled value="0">Select one</option>
</select2>
</div>
</form>
</div>
</div>
</transition>
</div>
</template>
Script
Vue.component('admin-access', {
template: '#admin-access',
props: ['options', 'value'],
created: function() {
$('#search-user-admin').select2({
placeholder: "Select User",
allowClear: true
});
},
data: function() {
return {
admin : true,
selected : false
}
},
});
Vue.component('select2', {
template: '#select2-template',
data: function() {
return {
selected: 0,
options: [
{ id: 1, text: 'Hello' },
{ id: 2, text: 'Darkness' },
{ id: 3, text: 'My' },
{ id: 4, text: 'Old' },
{ id: 5, text: 'Friend' }
]
}
},
mounted: function() {
var vm = this;
$(this.$el).select2({
data: this.options,
placeholder: "Select an option",
})
.val(this.value)
.trigger('change')
.on('change', function () {
vm.$emit('input', this.value);
});
},
watch: {
value: function (value) {
$(this.$el).val(value).trigger('change');
},
options: function (options) {
$(this.$el).select2({ data: options });
}
},
destroyed: function () {
$(this.$el).off().select2('destroy');
}
});
var admin = new Vue({
el: '#app'
});
There's nothing wrong with nesting components in the first place. But you have to keep in mind that nesting them, or just in general, just wrapping generic html components like a select into a Vue Component is very costly when it comes to rendering, especially when you are nesting them. Typically when all your component does is just wrapping a simple HTMl element with some styles, you should probably just use generic HTML with classes here, for performance sake.
Also, I'd try to get rid of all the jQuery code inside of Vue Components. Vue offers all the functionality that jQuery has and it'll just increase loading times further.
