I am wondering how I can attach links to items within a Vuetify autocomplete. I would like to do this so that it would act as a search bar. As of right now, I can attach links to the v-list-item but the link won't cover the entire width of the container. It appears to just form a link around the text instead of the entire item. I've tried to wrap the entire component but that doesn't seem to work either. I've also tried looking at the docs (https://vuetifyjs.com/en/components/autocompletes/) but I can't seem to find anything on making items links there either. Thanks for any help in advance.
<v-autocomplete
v-model="model"
:items="users"
:loading="isLoading"
:search-input.sync="search"
clearable
hide-details
hide-selected
item-text="username"
item-value="symbol"
placeholder="Search"
flat
solo
dense
>
<template v-slot:item="{ item }">
<v-list>
<v-list-item-group v-model="item">
<v-list-item-content>
<v-list-item link :to="'users/' + item.id">
{{item.username}}
</v-list-item>
</v-list-item-content>
</v-list-item-group>
</v-list>
</template>
</v-autocomplete>
The item slot should be <v-list-item/> only since the wrapping element of those item slots are <v-list/> already by default.
<v-autocomplete
...
>
<template v-slot:item="{ item }">
<v-list-item link :to="'users/' + item.id">{{item.username}}</v-list-item>
</template>
</v-autocomplete>
Here's a demo.
When using tag to override the tag used to create the link, how can I pass props to the created Vue component?
Here you can see that I am using a v-list-item tag inside of a v-list (not shown). This works as expected and the v-list-item is parsed by Vue as a Vuetify component. However, I can't figure out how to pass props to the v-list-item
<router-link
:to="{name: 'home'}"
tag="v-list-item"
>
<v-list-item-action>
<v-icon>mdi-home</v-icon>
</v-list-item-action>
<v-list-item-content>
<v-list-item-title>
Home
</v-list-item-title>
</v-list-item-content>
</router-link>
I've tried
<router-link
:to="{name: 'home'}"
tag="v-list-item"
:disabled="isDisabled"
>
...but it doesn't work.
You could use directly the v-list-item and add to prop to it by passing the path name :
<v-list-item :to="{name: 'home'}">
in the official API select v-list-item from the drop down and go to the to prop with description :
Denotes the target route of the link. You can find more information about the to prop on the vue-router documentation.
I have made a v-autocomplete but it highlights words/chars in the list that the user haven't typed.
the v-autocomplete code:
<v-autocomplete
:filter="() => true"
item-text="states.text"
:items="states"
filled
rounded
v-model="model"
:search-input.sync="search">
<template
slot="item"
slot-scope="{ parent,item }"
>
<v-list-tile-content >
<v-list-tile-title v-html="`${parent.genFilteredText(item.text)}`">
</v-list-tile-title>
</v-list-tile-content>
</template>
</v-autocomplete>
You can se it all in the codepen: https://codepen.io/maikenmadsen92/pen/ZEEZjYM?editors=1010
Is it possible just to highlight the words the user have typed in the input?
There are some issue with the implementation of you v-autocomplete.
You filter is useless since it will alway return true with is why all words/chars is highlights.
And the main issue is you item-text since following the doc vuetify
item-text :
Set property of items's text value
With mean you item-text=text since the items is already set to states.
<v-autocomplete
item-text="text"
:items="states"
filled
rounded
v-model="model"
:search-input.sync="search">
<template
slot="item"
slot-scope="{ parent,item }"
>
<v-list-tile-content >
<v-list-tile-title v-html="`${parent.genFilteredText(item.text)}`">
</v-list-tile-title>
</v-list-tile-content>
</template>
</v-autocomplete>
i am able to use getMaskedCharacters to do the trick
Looking at the Vuetify example code for v-toolbar, what is the purpose of v-slot:activator="{ on }"? For example:
<template v-slot:activator="{ on }">
<v-toolbar-title v-on="on">
<span>All</span>
<v-icon dark>arrow_drop_down</v-icon>
</v-toolbar-title>
</template>
<script>
export default {
data: () => ({
items: [
'All', 'Family', 'Friends', 'Coworkers'
]
})
}
</script>
As far as I can see, on is not a defined variable anywhere, so I don't see how this is working. When I try it in my project, Internet Explorer throws an error on the <template v-slot:activator="{ on }">, but if I remove it, the page renders.
You're likely referring to this example:
<v-toolbar color="grey darken-1" dark>
<v-menu :nudge-width="100">
<template v-slot:activator="{ on }">
<v-toolbar-title v-on="on">
<span>All</span>
<v-icon dark>arrow_drop_down</v-icon>
</v-toolbar-title>
</template>
...
</v-menu>
</v-toolbar>
The following line declares a scoped slot named activator, and it is provided a scope object (from VMenu), which contains a property named on:
<template v-slot:activator="{ on }">
This uses destructuring syntax on the scope object, which IE does not support.
For IE, you'd have to dereference on from the scope object itself:
<template v-slot:activator="scope">
<v-toolbar-title v-on="scope.on">
But the ideal solution IMO is to use a Vue CLI generated project, which includes a Babel preset (#vue/babel-preset-app) to automatically include the transforms/polyfills needed for the target browsers. In this case, babel-plugin-transform-es2015-destructuring would be automatically applied during the build.
Details on the activator slot
VMenu allows users to specify a slotted template named activator, containing component(s) that activate/open the menu upon certain events (e.g., click). VMenu provides listeners for those events via an object, passed to the activator slot:
<v-menu>
<template v-slot:activator="scopeDataFromVMenu">
<!-- slot content goes here -->
</template>
</v-menu>
The slot content can access VMenu's event listeners like this:
<v-menu>
<template v-slot:activator="scopeDataFromVMenu">
<button v-on="scopeDataFromVMenu.on">Click</button>
</template>
</v-menu>
For improved readability, the scoped data can also be destructured in the template:
<!-- equivalent to above -->
<v-menu>
<template v-slot:activator="{ on }">
<button v-on="on">Click</button>
</template>
</v-menu>
The listeners from the scope object are passed to the <button> with v-on's object syntax, which binds one or more event/listener pairs to the element. For this value of on:
{
click: activatorClickHandler // activatorClickHandler is an internal VMenu mixin
}
...the button's click handler is bound to a VMenu method.
I think the original question is about understanding the "on" object. It is best explained here:
https://github.com/vuetifyjs/vuetify/issues/6866
Essentially "on" is a prop passed in from the activator. What v-on="on" does is bind that on prop to the component. "on" itself is all of the event listeners passed from the activator.
To call out a readability tip, it's possible to use this syntax:
<v-menu>
<template v-slot:activator="{ on: activationEvents }">
<v-btn v-on="activationEvents">
I like turtles 🐢
</v-btn>
</template>
</v-menu>
In my brain this has a more fluent readability than v-on="on", which to me is like observing a conversation consisting solely of:
Person 1: "Hey"
Person 2: "Yep"
Understand? ;)
By the way, activationEvents could be any alias, like "slotEvents", "listeners", "anyOldEvent", or whatever makes more sense to the reader as a renaming of the mysterious on.
Run the below code,you will know what is 'attrs' an 'on' in v-menu.
<v-menu>
<template v-slot:activator="{ on, attrs }">
<div v-bind="attrs" v-on="on">
v-menu slot activator:
<br />
attrs == {{ JSON.stringify(attrs) }}
<br />
on == {{ '{' + Object.keys(on).map(k => k + " : " + on[k]).join(',') + '}' }}
</div>
</template>
</v-menu>
Result:
v-menu slot activator:
attrs == {"role":"button","aria-haspopup":true,"aria-expanded":"false"}
on == {
click:function (e) {if (_this.openOnClick) {onClick && onClick(e);}_this.absoluteX = e.clientX;_this.absoluteY = e.clientY;},
keydown:function () { [native code] }
}
Explanation:
<div v-bind="attrs" v-on="on"> equals
<div
v-bind="{role:'button',aria-haspopup:true,aria-expanded:'false'}"
v-on="{click:function (e) {/*implement by v-menu*/},keydown:function () {/*implement by v-menu*/}}"
>
Starting in vue 2.4.0+, v-on also supports binding to an object of event/listener pairs without an argument. Note when using the object syntax, it does not support any modifiers.
Example:
<!-- v-on's object syntax (vue 2.4.0+) -->
<button v-on="{ mousedown: doThis, mouseup: doThat }"></button>
About <template> tags in Internet Explorer throws an error :
as vuetify docs say:
Template caveat
Due to Internet Explorer’s limited support for <template> tags, you must send fully compiled dom elements to the browser. This can be done by either building your Vue code in advance or by creating helper components to replace the dom elements. For instance, if sent directly to IE, this will fail:
<!-- Vue Component -->
<template v-slot:items="props">
<td>{{ props.item.name }}</td>
</template>
I am trying to figure out how to add the exact property to the root link in a dynamically loaded menu. The menu entries are loaded from a REST API.
Currently the root path is always matched since it does not contain the exact property. In similar examples the root link is hard coded which I want to avoid.
This is the route that should be matched exactly
{ path: '/', component: HomePage }
The router-link is part of the menu, which is loaded via axios from the REST API and mapped to the state, including the root link "/". How can I access only this one item in the for loop to add the exact property?
<router-link tag="li" class="link" v-for="item in menu" v-bind:key="item.id" :to="item.slug">{{ item.content }}</router-link>
May be I am missing something, or there is a better way to achieve this?
Many thanks
Conditionally bind the exact prop like this.
<router-link tag="li" class="link" v-for="item in menu" :key="item.id" :to="item.slug" :exact="item.slug === '/' ? true : false">
{{ item.content }}
</router-link>
Have you ever try
<router-link tag="li" class="link" v-for="item in menu" v-bind:key="item.id" :to="item.slug" v-bind={ "exact": item.slug === "/" ? true : false }>{{ item.content }}</router-link>
