I want to implement a pagination component b-pagination w/bootstrap-vue but it will only display page one. I am following the setup in documentation but they only show an example using a table not an unordered list. I have :
<template>
<div class="results overflow-auto" v-cloak>
<h3>Search Results</h3>
<modal v-if="showModal" #close="showModal = false">
<!--
you can use custom content here to overwrite
default content
-->
<template v-slot:header>
<h1>NASA Image</h1>
</template>
<template v-slot:body>
<b-img class="modal-image" v-bind:src="attribute"></b-img>
</template>
</modal>
<!-- ======== Pagination Markup ============ -->
<b-pagination
v-model="currentPage"
:total-rows="rows"
:per-page="perPage"
:items="items"
aria-controls="my-list"
></b-pagination>
<p class="mt-3">Current Page: {{ currentPage }}</p>
<!-- ==========End Pagination Markup ======== -->
<!-- Limit output to 100 items -->
<ul
class="search-results"
id="my-list"
>
<li v-for="(item, index) in propsResults.items.slice(0,100)" :key="index">
{{ item.data[0].title}}
<span>
<b-img
thumbnail
class="thumbnail"
:src="item.links[0].href"
alt="Fluid image"
id="show-modal"
v-on:click="imageModal"
></b-img>
</span>
</li>
</ul>
</div>
</template>
and my javascript is :
export default {
name: "SearchResults",
props: ["propsResults"],
data() {
return {
showModal: false,
attribute: "",
perPage: 10,
currentPage: 1,
items: this.$props.propsResults.items
};
},
computed: {
rows() {
return this.$props.propsResults.items.length;
}
}
The pagination component is displaying all 100 items of items array on one page. I should also note I do not see the items array in the b-pagination props object per Vue dev tools in FF. is this normal? Any insight appreciated..
You should still be using currentPage to choose which items to show. The b-pagination component only changes that number.
Try using this line:
<li v-for="(item, index) in items.slice(10*(currentPage-1),10*(currentPage))" :key="index">

I'm a beginner in web development and I'm trying to help out friends restarting an old game. I'm in charge of the tooltip component but I hit a wall...
There are many Vue components and in a lot of them I want to call a child component named Tooltip, I'm using vue-tippy for easy configuration. This is the component:
<template>
<tippy class="tippy-tooltip">
<slot name='tooltip-trigger'></slot>
<template #content>
<slot name='tooltip-content'>
</slot>
</template>
</tippy>
</template>
<script>
import { formatText } from "#/utils/formatText";
export default {
name: "Tooltip",
methods:{
formatContent(value) {
if (! value) return '';
return formatText(value.toString());
}
},
}
</script>
In one of the other components I try to use the tooltip:
<template>
<a class="action-button" href="#">
<Tooltip>
<template #tooltip-trigger>
<span v-if="action.movementPointCost > 0">{{ action.movementPointCost }}<img src="#/assets/images/pm.png" alt="mp"></span>
<span v-else-if="action.actionPointCost > 0">{{ action.actionPointCost }}<img src="#/assets/images/pa.png" alt="ap"></span>
<span v-if="action.canExecute">{{ action.name }}</span>
<span v-else><s>{{ action.name }}</s></span>
<span v-if="action.successRate < 100" class="success-rate"> ({{ action.successRate }}%)</span>
</template>
<template #tooltip-content>
<h1>{{action.name}}</h1>
<p>{{action.description}}</p>
</template>
</Tooltip>
</a>
</template>
<script>
import Tooltip from "#/components/Utils/ToolTip";
export default {
props: {
action: Object
},
components: {Tooltip}
};
</script>
From here everything is fine, the tooltip is correctly displayed with the proper content.
The thing is, the text in the {{ named.description }} needs to be formatted with the formatContent content. I know I can use the props, the components would look like that:
Tooltip.vue:
<template>
<tippy class="tippy-tooltip">
<slot name='tooltip-trigger'></slot>
<template #content>
<h1 v-html="formatContent(title)" />
<p v-html="formatContent(content)"/>
</template>
</tippy>
</template>
<script>
import { formatText } from "#/utils/formatText";
export default {
name: "Tooltip",
methods:{
formatContent(value) {
if (! value) return '';
return formatText(value.toString());
}
},
props: {
title: {
type: String,
required: true
},
content: {
type: Array,
required: true
}
}
}
</script>
Parent.vue:
<template>
<a class="action-button" href="#">
<Tooltip :title="action.name" :content="action.description">
<template v-slot:tooltip-trigger>
<span v-if="action.movementPointCost > 0">{{ action.movementPointCost }}<img src="#/assets/images/pm.png" alt="mp"></span>
<span v-else-if="action.actionPointCost > 0">{{ action.actionPointCost }}<img src="#/assets/images/pa.png" alt="ap"></span>
<span v-if="action.canExecute">{{ action.name }}</span>
<span v-else><s>{{ action.name }}</s></span>
<span v-if="action.successRate < 100" class="success-rate"> ({{ action.successRate }}%)</span>
</template>
</Tooltip>
</a>
</template>
<script>
import Tooltip from "#/components/Utils/ToolTip";
export default {
props: {
action: Object
},
components: {Tooltip}
};
</script>
But I need to use a slot in the tooltip component because we'll have some "extensive" lists with v-for.
Is there a way to pass the data from a slot into a JS function?
If I understand you correctly, you're looking for scoped slots here.
These will allow you to pass information (including methods) from child components (the components with <slot> elements) back to the parents (the component(s) filling those slots), allowing parents to use chosen information directly in the slotted-in content.
In this case, we can give parents access to formatContent(), which will allow them to pass in content that uses it directly. This allows us to keep the flexibility of slots, with the data passing of props.
To add this to your example, we add some "scope" to your content slot in Tooltip.vue. This just means we one or more attributes to your <slot> element, in this case, formatContent:
<!-- Tooltip.vue -->
<template>
<tippy class="tippy-tooltip">
<slot name='tooltip-trigger'></slot>
<template #content>
<!-- Attributes we add or bind to this slot (eg. formatContent) -->
<!-- become available to components using the slot -->
<slot name='tooltip-content' :formatContent="formatContent"></slot>
</template>
</tippy>
</template>
<script>
import { formatText } from "#/utils/formatText";
export default {
name: "Tooltip",
methods: {
formatContent(value) {
// Rewrote as a ternary, but keep what you're comfortable with
return !value ? '' : formatText(value.toString());
}
},
}
</script>
Now that we've added some scope to the slot, parents filling the slot with content can use it by invoking a slot's "scope":
<!-- Parent.vue -->
<template>
<a class="action-button" href="#">
<Tooltip>
. . .
<template #tooltip-content="{ formatContent }">
<!-- Elements in this slot now have access to 'formatContent' -->
<h1>{{ formatContent(action.name) }}</h1>
<p>{{ formatContent(action.description) }}</p>
</template>
</Tooltip>
</a>
</template>
. . .
Sidenote: I prefer to use the destructured syntax for slot scope, because I feel it's clearer, and you only have to expose what you're actually using:
<template #tooltip-content="{ formatContent }">
But you can also use a variable name here if your prefer, which will become an object which has all your slot content as properties. Eg.:
<template #tooltip-content="slotProps">
<!-- 'formatContent' is now a property of 'slotProps' -->
<h1>{{ slotProps.formatContent(action.name) }}</h1>
<p>{{ slotProps.formatContent(action.description) }}</p>
</template>
If you still need the v-html rendering, you can still do that in the slot:
<template #tooltip-content="{ formatContent }">
<h1 v-html="formatContent(title)" />
<p v-html="formatContent(content)"/>
</template>
I'm trying to allow duplicates in Vue bootstrap's form tags.
I've tried using :tag-validator (in the example) and #tag-state to externally modify the v-model value. However it seems like it is getting rid of the duplicate somewhere. Is this impossible?
Jsfiddle of the example: https://jsfiddle.net/yts54fpd/.
<div id="app">
<template>
<div>
<b-form-group label="Tagged input using select" label-for="tags-component-select">
<!-- Prop `add-on-change` is needed to enable adding tags vie the `change` event -->
<b-form-tags
:tag-validator="tagValidator"
id="tags-component-select"
v-model="value"
size="lg"
class="mb-2"
add-on-change
no-outer-focus
>
<template v-slot="{ tags, inputAttrs, inputHandlers, disabled, removeTag }">
<ul v-if="tags.length > 0" class="list-inline d-inline-block mb-2">
<li v-for="tag in tags" :key="tag" class="list-inline-item">
<b-form-tag
#remove="removeTag(tag)"
:title="tag"
:disabled="disabled"
variant="info"
>{{ tag }}</b-form-tag>
</li>
</ul>
<b-form-select
v-bind="inputAttrs"
v-on="inputHandlers"
:disabled="disabled"
:options="options"
>
<template #first>
<!-- This is required to prevent bugs with Safari -->
<option disabled value="">Choose a tag...</option>
</template>
</b-form-select>
</template>
</b-form-tags>
</b-form-group>
</div>
</template>
</div>
window.onload = () => {
new Vue({
el: '#app',
data() {
return {
options: ['Apple', 'Orange', 'Banana', 'Lime', 'Peach', 'Chocolate', 'Strawberry'],
value: []
}
},
methods: {
tagValidator(tag) {
this.value.push(tag)
return true
}
}
})
}
I'm trying to make a condition to enable a named slot like this:
<template v-slot:item="{ item }" v-if="item.loading">
<v-progress-circular indeterminate color="primary"></v-progress-circular>
</template>
My use case is a Vuetify datatable: each item has a "loading" property, and I'd like to activate "item" slot only if the row is loading ("item" slot is Slot to replace the default rendering of a row)
The error is that item is undefined in the v-if, which seems logic : item is only defined for template children tag.
Is there a way to solve this problem?
You can filter the items that you pass to the datatable with a computed property.
Can you just not swap element based on loading ?
Vue.config.devtools = false;
Vue.config.productionTip = false;
var app = new Vue({
el: '#app',
data: {
items: [{data : "", loading: true}, {data : "Some data", loading: false}]
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<div v-for="item in items">
<div>
<div v-if="item.loading">
Loading...
</div>
<div v-else>
{{item.data}}
</div>
</div>
</div>
</div>
I had a similar problem, and I solved it in Vuetify 2 by importing VDataTable/Row as 'v-data-table-row', and using it to render 'regular' table rows, and for custom rows I used my own template.
JavaScript
import Row from 'vuetify/lib/components/VDataTable/Row.js';
export default {
components: { 'v-data-table-row': Row },
data() {
return {
currentItemName: 'Ice cream sandwich'
}
}
// headers, items, etc...
}
HTML
<template v-slot:item="{ item }">
<tr v-if="item.name == currentItemName" class="blue-grey lighten-4">
<td>Custom prefix - {{ item.name }}</td>
<td colspan="2">{{ item.calories }} - Custom suffix</td>
</tr>
<v-data-table-row v-else :headers="headers" :item="item">
<template
v-for="(index, name) in $scopedSlots"
v-slot:[name.substr(5)]="data"
>
<slot
v-if="name.substr(0, 5) === 'item.'"
:name="name"
v-bind="data"
></slot>
</template>
</v-data-table-row> </template
You can check out working example here.
You can just put the v-if on the child element
<template #item="{ item }">
<v-progress-circular
v-if="item.loading"
color="primary"
indeterminate
></v-progress-circular>
</template>
I have a div that when i want hover to it, it will show other div. However, my first div is dynamic, it has an ID. So how will i able to hover to ID based on its ID?
It should be #mouseenter="hoverService{{services.id}} = true" but it causes error. So i made the code below to just static.
Here's my code below:
<template>
<div
class="col-md-3"
v-for="(services, index) in servicesFiltered"
:key="index"
#mouseenter="hoverService = true"
#mouseleave="hoverService = false"
>
<div class="service_background" v-if="hoverService">
<div class="mb-1" v-for="(sub_services, index) in services.menu_items" :key="index">
<router-link
:to="{ path: `/${sub_services.data}`}"
>
<a
href="#"
class="btn btn-outline-primary w-100 services_button"
>{{sub_services.text }}</a>
</router-link>
</div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
hoverService: false
};
}
};
</script>
Try this code

You need to maintain hover for each item you can not manipulate using single variable for multiple items.
I'm new in VueJS and I'm try to do something like this
I have 3 components, siderbar ; siderbar-item and sidebar-drop
siderbar.vue is a wrapper when you can put siderbar-item and sidebar-drop, and inside sidebar-drop you can put sidebar-item too
for example:
<sidebar>
<sidebar-item url="myurl" title="Dashboard" icon="fas fa-tachometer-alt" badge=""></sidebar-item>
<sidebar-drop title="News" icon="fas fa-tachometer-alt">
<sidebar-item url="myurl_news" title="News list" icon="fas fa-tachometer-alt" badge=""></sidebar-item>
<sidebar-item url="myurl_news_add" title="Add News" icon="fas fa-tachometer-alt" badge=""></sidebar-item>
</sidebar-drop>
<sidebar-drop title="Categories" icon="fas fa-tachometer-alt">
<sidebar-item url="myurl_categories" title="Categories List" icon="fas fa-tachometer-alt" badge=""></sidebar-item>
</sidebar-drop>
</sidebar>
sidebar.vue is very simple:
<aside>
<slot></slot>
</aside>
sidebar-item.vue
<template>
<ul class="menu-list" >
<li>
<a :href="url" :class="{'is-active': is_active }">
<span class="icon"><i v-if="icon" :class="icon"></i></span>
{{ title }}
<span v-if="badge" class="button badge is-info is-small is-pulled-right "> {{ badge }}</span>
</a>
</li>
</ul>
</template>
<script>
export default {
props: ['title', 'url', 'icon', 'badge'],
data() {
return {
is_active: this.$current_url === this.url
}
}
}
</script>
and sidebar-drop.vue
<template>
<ul class="menu-list" v-if="title">
<li #click="openMenu" :class="{'is-open': is_open}">
<a class="">
<span v-if="icon" class="icon"><i class="fas fa-tachometer-alt"></i></span>
{{ title }}
<span class="badge is-pulled-right" style=""> <i class="fas fa-chevron-left"></i> </span>
</a>
<slot></slot>
</li>
</ul>
</template>
<script>
export default {
props: ['title', 'icon'],
data() {
return {
is_open: false,
}
},
methods: {
openMenu(){
this.is_open = !this.is_open;
},
}
}
</script>
It works great, but I have a little problem. If you notice, sidebar-item has a data called "is_active", it only put a CSS class that this item is active. Great.
Now I'm trying to get into sidebar-drop if a least one of his children has data "is-active" in true, change the is_open sidebar-drop parent data to true.
Example: I click "News" item.
Ul li News is active... works!
Ul li parent drop is open... don't work
Is possible make that?
Thanks everyone!
Update:
I put it in Fiddler to more clear:
https://jsfiddle.net/h35qy2zs/
I do in sidebar-item a random is_active.
If any child of sidebar-drop (sidebar-item's) data is_active:true, sidebar-drop data is_open is true too.
So, it show in color yellow and open
Result:
But now, both are closed at refresh page.
