I try to create a layout with element.io which has a collapsing sidebar menu.
It works quite well, the only problem is that I do not gain anything since the width of the menu and the content part are fixed.
My code looks like this:
<template>
<el-row>
<el-col :span="4">
<template>
<el-menu :router="true"
:default-active="$route.path"
background-color="#545c64"
text-color="#fff"
active-text-color="#ffd04b"
:collapse="isCollapse"
class="el-menu-vertical-demo"
>
<template v-for="rule in routes">
<el-menu-item :index="rule.path">
<i :class="rule.icon"></i>
<span slot="title">{{ rule.name }}</span>
</el-menu-item>
</template>
</el-menu>
</template>
</el-col>
<el-col :span="20">
<el-row>
<el-radio-group v-model="isCollapse" style="margin-bottom: 20px;">
<el-radio-button :label="true" :disabled="isCollapse" border>
<i class="fas fa-caret-left"></i>
</el-radio-button>
<el-radio-button :label="false" :disabled="!isCollapse" border>
<i class="fas fa-caret-right"></i>
</el-radio-button>
</el-radio-group>
</el-row>
<el-row>
<router-view></router-view>
</el-row>
</el-col>
</el-row>
</template>
<script>
export default {
data() {
return {
routes: this.$router.options.routes,
activeLink: null,
isCollapse: false
};
},
mounted: function () {
},
methods: {
}
};
</script>
How can I fix it so the content block will occupy 100% of the available width?
Ok, I found a simple solution.
First, I moved to element-io elements. The menu is now embedded inside el-aside tag, while the main part is embedded inside an el-container tag.
Second, I added a dynamic css class to the el-aside tag:
<el-aside v-bind:class="[isCollapse ? 'menu-collapsed' : 'menu-expanded']">
Now, if you don't want to mess around with transitions, simply add to the el-menu component :collapse-transition="false" and that's it!

My index page has a Header and Home components.
{
path: "/",
name: "Homepage",
components: {
header: () => import("../components/layout/HomepageHeader.vue"),
main: () => import("../views/Home.vue"),
},
},
Both don’t have any scoped CSS, they only use Tailwind CSS classes. And that Tailwind CSS file is global.
The problem occurs when I programmatically redirect to my index page (for example, after I logged in). The HomepageHeader component doesn’t have all the CSS. Same with the Home.vue component.
Here’s the simplified code of the Header
<template>
<div class="w-full bg-white sm:shadow-lg mb-6">
<div class="mx-6">
<nav
class="px-3 flex flex-col sm:flex-row sm:px-4 sm:justify-between sm:h-16 list-none"
>
<li
class="text-center h-16 font-semibold text-red-500 text-lg sm:text-xl sm:h-16 table"
>
<div class=" py-4 sm:h-16">
<router-link to="/">Home</router-link>
</div>
</li>
<li>
<login-badge
class="shadow-lg md:shadow-none px-4 py-3 flex sm:px-0 sm:h-14 text-white"
></login-badge>
</li>
</nav>
</div>
</div>
</template>
When I say
“component doesn’t have all the CSS”
I mean that all the classes in the HomepageHeader.vue component don’t work. But the classes inside the child component LoginBadge.vue work fine!
What else can I say? I use router.replace("/"); to redirect to the homepage.
How do I fix that?
P.S. Just found out that the same thing happends when I go back to a previous page and that previous page is the index page.
P.P.S. global CSS is imported inside the App.vue
<template>
<router-view name="header"></router-view>
<main class="container mx-auto">
<router-view name="main"></router-view>
</main>
</template>
<script>
export default {
setup() {
return {};
},
};
</script>
<style>
#import "./assets/tailwind.css";
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 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 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: `/${sub_services.data}`}"
>
<a
href="#"
class="btn btn-outline-primary w-100 services_button"
>{{sub_services.text }}</a>
</router-link>
</div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
hoverService: false
};
}
};
</script>
Try this code
https://codesandbox.io/s/y7p9qyyovz
You need to maintain hover for each item you can not manipulate using single variable for multiple items.
I have a component like this:
<test></test>
I declare this as follows:
Vue.component('test', {
data: {
showModal: true
},
methods: {
displayComponentModalDialog: function() {
this.showModal = true;
}
},
template: `<button #click='displayComponentModalDialog'>test</button>`
});
The <test></test> component is then placed somewhere inside the <div id="#app"> wrapper.
var app = new Vue({
router,
el: '#app',
// etc.
})
Now, I want to display another component inside the test component. So in this case I want a dialog to appear after I click the button in test component. I am not able to achieve this.
What I did is adding a new component:
Vue.component('dialog', {
template: '#dialog-template'
});
And then the following code, although I do not know for sure where to put it.
<!-- template for the modal component -->
<script type="text/x-template" id="dialog-template">
<transition name="dialog">
<div class="modal-mask">
<div class="modal-wrapper">
<div class="modal-container">
<div class="modal-header">
<slot name="header">
default header
</slot>
</div>
<div class="modal-body">
<slot name="body">
default body
</slot>
</div>
<div class="modal-footer">
<slot name="footer">
<button class="btn btn-primary" #click="$emit('close')">
OK
</button>
</slot>
</div>
</div>
</div>
</div>
</transition>
</script>
<!-- use the modal component, pass in the prop -->
<dialog v-if="showModal" #close="showModal = false">
<h3 slot="header">header</h3>
<p slot="body">
test
</p>
</dialog>
I tried putting this code inside the <test></test> but doesn't work. If I put it inside the template attribute in the component structure, it complains about only one root element.
So it is clear I miss some basic conception how this actually works in VueJS. Someone can help me clarify? Thanks.
As far as I can see your component indeed doesn't have a root tag. Templates have to have a root tag.
This is NOT a valid Vue template:
<div>
<h1>Stuff</h1>
</div>
<h2>Other stuff</h2>
This IS a valid Vue template:
<div>
<div>
<h1>Stuff</h1>
</div>
<h2>Other stuff</h2>
</div>
Note that in the second version we have a single root element for the template, a <div>, whereas in the first one we do not.
You have both a <script></script> and a <dialog></dialog> in your component template.
if you want to add another component in your test component . you can use slot on it.
You can refer to this documentation: https://v2.vuejs.org/v2/guide/components-slots.html
Example:
//component 1
<template>
<div id="modal">
// do something for your modal here.
<slot></slot> // reserve area for your another html or component.
</div>
</template>
// component 2
<template>
<your-modal-component>
<another-component>
</your-modal-component>
</template>
