I would like to automatically include the contents of one component in a named slot of another component. I.e., something like this:
Vue.component('comp-one', {
template: `
<div class="comps>
<div class="comp-two">
<slot name="compTwo"></slot>
</div>
<div class="comp-one">
<slot></slot>
</div>
</div>
`
})
Vue.component('comp-two', {
slot: 'compTwo',
template: `
<div class="sub-comp-two">
<!-- content goes here -->
<slot></slot>
</div>
`
})
The idea is that if someone uses <comp-two>Some content</comp-two>, it will automatically get added to the slot compTwo in comp-one. Is there a way to do this?
NOTE: I made up slot: 'compTwo'. Just trying to illustrate what I'd like to accomplish.

I wonder how to add components as slot content. Instead of doing it like:
<template v-slot:content>CONTENT HERE</template>
I'd like to pass a component.
PkDynModalCenter:
<div class="...">
<div id="modalIndicator" class="...">
<slot name="content"></slot>
</div>
</div>
Parent:
<PkDynModalCenter v-if="togglePayment" #closeModal="togglePayment = false">
<PaymentTemplate :info="voucherInfo" name="content"></PaymentTemplate>
</PkDynModalCenter>
But it's not displayed. Docs are very vague there...
Have a look at the docs for named slots: https://vuejs.org/guide/components/slots.html
You can only use your parent code with the default slot, so your PkDynModalCenter should look like this:
<div class="...">
<div id="modalIndicator" class="...">
<slot></slot> <!-- no name → default slot -->
</div>
</div>
With your current code for the modal, you can only call it like you did in your first code snippet.
How to render a div/component in other places on my component without make the duplicate content as separate component in vue? or separate the duplicate content from the targets?
for example this is the div I want to duplicate:
<div>blabla {{somecontent}}</div>
and I want to render in those places (all the code should be in one component):
<section>
<div> __HERE__ </div>
</section>
<section>
<div> __HERE__ </div>
</section>
I think want I expect is something like this:
<div #blabla>blabla {{somecontent}}</div>
<section>
<div> {{blabla}} </div>
</section>
<section>
<div> {{blabla}} </div>
</section>
A good solution is creating a Vue component. I always try to create component. AS question demand I give a solution here.
You can create a computed or a method that will render the component like this
<script>
...,
computed: {
renderBlaBla() {
return `<div #blabla>blabla ${this.somecontent}</div>`
}
},
....
</script>
and in the template section
<section>
<div v-html="renderBlaBla"></div>
</section>
<section>
<div v-html="renderBlaBla"></div>
</section>
I have a component like this:
<test></test>
I declare this as follows:
Vue.component('test', {
data: {
showModal: true
},
methods: {
displayComponentModalDialog: function() {
this.showModal = true;
}
},
template: `<button #click='displayComponentModalDialog'>test</button>`
});
The <test></test> component is then placed somewhere inside the <div id="#app"> wrapper.
var app = new Vue({
router,
el: '#app',
// etc.
})
Now, I want to display another component inside the test component. So in this case I want a dialog to appear after I click the button in test component. I am not able to achieve this.
What I did is adding a new component:
Vue.component('dialog', {
template: '#dialog-template'
});
And then the following code, although I do not know for sure where to put it.
<!-- template for the modal component -->
<script type="text/x-template" id="dialog-template">
<transition name="dialog">
<div class="modal-mask">
<div class="modal-wrapper">
<div class="modal-container">
<div class="modal-header">
<slot name="header">
default header
</slot>
</div>
<div class="modal-body">
<slot name="body">
default body
</slot>
</div>
<div class="modal-footer">
<slot name="footer">
<button class="btn btn-primary" #click="$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>
So I currently have a template sitting in a ".vue" file like so:
<template>
<div id="dataAttachToMe"></div>
</template>
I don't want this to load, unless a user clicks a button, something like
<button #click="loadTheTemplateAbove">See Data</button>
I've tried using this example:https://v2.vuejs.org/v2/guide/conditional.html#Controlling-Reusable-Elements-with-key. But it says something like "Component template should contain exactly one root element" in the error message.
I need more than a show/hide here I think, something that can initiate the template dynamically.
<template>
<div id="data">
<button #click="loadTemplate">Load the template</button>
<div v-if="buttonClicked">
<div id="dataAttachedToThisDiv"></div>
</div>
</div>
</template>
The error you are getting, means that there is more than one root element inside <template></template> tag.
It is required in Vue.js (and other template based frameworks/libraries) to have only one root element.
This will NOT work:
<template>
<div id="dataAttachToMe"></div>
<button #click="loadTheTemplateAbove">See Data</button>
</template>
This will work:
<template>
<div id="someRootDiv">
<div id="dataAttachToMe">Some data</div>
<button #click="loadTheTemplateAbove">See Data</button>
</div>
</template>
Here is a code example (App.vue) of what you are trying to achieve:
Basic idea: we have to create a variable, that will be changed upon button click. We add v-if directive that depends on that variable and will handle element's visibility.
Welcome to StackOverflow. When you get the error Component template should contain exactly one root element it means that you can only have one root element in your template. You can fix that error by wrapping everything in a blank div like so
<template>
<div>
<template v-if="loginType === 'username'">
<label>Username</label>
<input placeholder="Enter your username">
</template>
<template v-else>
<label>Email</label>
<input placeholder="Enter your email address">
</template>
</div>
</template>
Please edit your post and place you <script> tag. Conditional Rendering requires a data field of a boolean that you can place in your if statement on your template
<template>
<div>
<div v-if="show">{{message}}</div>
<div v-if="#show">Not Showing when show is set to false</div>
<button v-on:click="show = true">Show</button>
</div>
</template>
<script>
module.exports {
data: function () {
message: 'Hello Vue!',
show: false
}
}
</script>
I am new to Vuejs. This is what I need to do.
<div v-for="r in records">
<div v-if="r.something">
<div id="x">
{{ r. something}}
more of r here.
</div>
</div>
<div v-else id="x">
same div as in the block above.
</div>
</div>
What I want do is not define div with id x two times as it is huge.
Make your 'div' a component and refer to it in both places.
There are many ways to define your component. This is example shows just one. If you are using WebPack, use a single file component. You can then have your script, html, and css all in one file that gets precompiled. That's the best way to manage your 'huge' div. Then you can continue to refactor and break it up into more components.
const myComponent = {
template: "<div :id='id'>HELLO, my id is {{id}}. r.foo is {{r.foo}} </div>",
props: {
id: String
},
data() {
return {
r: {
foo: 'bar'
}
}
}
}
<div v-for="r in records">
<div v-if="r.something">
<my-component id='x' />
</div>
<div v-else id="x">
<my-component id='x' />
</div>
</div>
