Im new to VueJS and trying to figure out how I would nest components or have sub components. I don't know if im very bad at googling but I couldn't really find a clear answer.
This is my script and html :
Vue.component('card', {
template: '<div class="card"></div>'
})
Vue.component('card-text', {
props: ['text-content'],
template: '{{ text-content }}'
})
new Vue({
el: '#app',
})
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<link rel="stylesheet" href="style.css">
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script defer src="script.js"></script>
</head>
<body>
<div id="app">
<card>
<card-text text-content="Text to show"></card-text>
</card>
</div>
</body>
</html>
as you can see I have 2 components, card and card-text.
I want to display these like this :
<card>
<card-text text-content="text to show"></card-text>
</card>
You would need slots to do that. Just change your card component to:
Vue.component('card', {
template: '<div class="card"><slot></slot></div>'
})
To be able to render different stuff inside <card></card>
You can read more in the docs
If you want to nest card-text inside card, just do as follows:
Vue.component('card', {
template: '<div class="card"><card-text text-content="Text to show"></card-text></div>'
})

I am new to VueJs. As a start, I am trying to create a page which on button click increases or decreases age. However, the age is not rendering on to the html. Given below are the reqd files:
HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Vue</title>
<script src="https://unpkg.com/vue#2.6.11/dist/vue.js"></script>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div id="app">
<h1>Events</h1>
<button #click="add">Add a year</button>
<button #click="subtract">Subtract a year</button>
<p>{{ age }}</p>
</div>
<script src="app.js"></script>
</body>
</html>
app.js:
new Vue({
el: '#app',
data: {
age:22
},
methods: {
add: function(){
this.age++;
}
subtract: function(){
this.age--;
}
}
});
Any help is appreciated!
problem is missing comma symbol after add function :D .
Correct version of app.js as below :
new Vue({
el: '#app',
data: {
age:22
},
methods: {
add: function(){
this.age++;
},
subtract: function(){
this.age--;
}
}
});
I am new in vue. i tried to render a vue component. but i got error.
i am not using vue-cli. i include a script https://cdn.jsdelivr.net/npm/vue

<link href="stylee.css" rel="stylesheet">
<script src="https://cdn.jsdelivr.net/npm/vue"></script>

app.js
import Index from "./Index.vue"
new Vue({
el: '#head',
render: h => h(Index)
});
both app.js and Index.vue are in same folder.
Please healp me to solve this..
The error occurs because browser do not recognize import statement.
Since you are not using a bundler like webpack you can register the components using Vue.component(). This will eliminate the need to import components inside other modules.
Vue.component('Index', {
data() {
return {
value: 'Index component'
}
},
template: `<h2>{{ value }}</h2>`
})
new Vue({
el: '#head'
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<!DOCTYPE html>
<html>

I always build my SPA apps with the vue-cli.
This time I'm building a small project and I'm incluing Vue with a script tag.
But I don't understand the following behavior.
// app.js
Vue.component('todo-item', {
template: `<div>Todo Component!</div>`
})
var app = new Vue({
el: '#app',
data: {
message: 'Hello Vue App!'
}
})
The HTML index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Title</title>
</head>
<body>
<div id="app">
{{ message }}
<div>
Just some content...
</div>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script src="./js/app.js"></script>
</body>
</html>
The result is this:
Now, I'll try to add '<todo-item />' Component inside the HTML:
<div id="app">
{{ message }}
<todo-item />
<div>
Just some content...
</div>
</div>
The text 'Just some content...' disappeared:
What Am I doing wrong?
TL;DR;
instead of <todo-item/> use <todo-item></todo-item>
Un-compiled vue.js does not support self-closing html tags.
see style guide:
Unfortunately, HTML doesn’t allow custom elements to be self-closing -
only official “void” elements. That’s why the strategy is only
possible when Vue’s template compiler can reach the template before
the DOM, then serve the DOM spec-compliant HTML.
https://v2.vuejs.org/v2/style-guide/#Self-closing-components-strongly-recommended

I am new to Vue.js and am trying to create a sample component as per the code below but ending up with "[Vue warn]: Error when rendering component <my-tag>: " I have looked at stackoverflow for a similar question asked before but that did not help. The code for component is as below:
Vue.component('my-tag', {
props: ['myTagAttr'],
template: '<span>{{myTagAttr.text}}</span>'
})
var data = {
myTagAttrVal: {
text: 'foobar',
color: 'Red'
}
}
var vm = new Vue({
el: '#demo',
data: data
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.0.3/vue.js"></script>

</head>
<body>
<span id='demo'>
<my-tag v-bind:myTagAttr='myTagAttrVal'></my-tag>
</span>
</body>
</html>
Alternatively, code can be found at JSbin
HTML attributes are case-insensitive, so when using non-string templates, camelCased prop names need to use their kebab-case (hyphen-delimited) equivalents :
<my-tag v-bind:my-tag='myTagAttrVal'></my-tag>
Here is a working fiddle: https://jsfiddle.net/nxcbm6na/
You can find the details in the documenation

Closed 5 years ago.
Here is my code and i seem to have done everything correctly.
what might be the problem as the output is only {{message}}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<div id="app">
<h1>{{message}}</h1>
</div>
<script src="https://vuejs.org/js/vue.js"/>
<script>
new Vue({
el: '#app',
data:{
message: "Yow"
},
mounted: function () {
console.log("Mounted")
}
});
</script>
</body>
</html>
and it just outputs {{message}}
Hey man you forgot to close ending script tag in vue.js script/api
You were rendering whole html part in script tag like you can see in console below :
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<div id="app">
<h1>{{message}}</h1>
</div>
<script src="https://vuejs.org/js/vue.js"/>
</script>
<script>
console.log('hi');
var app = new Vue({
el: '#app',
data:{
message: 'yow'
},
mounted: function () {
console.log("Mounted")
}
});
</script>
</body>
And always inlude api/main/cdn link ahead of any operational js file
