When I import a component with VueJs content into another component with VueJs content I get this error:
Templates should only be responsible for mapping the state to the UI. Avoid placing tags with side-effects in your templates, such as <style>, as they will not be parsed.
example.blade.php is the component
<div id="appComp">
#{{ msg }}
</div>
<script>
var appComp = new Vue({
el: '#appComp',
data: {
msg : #json($msg),
}
});
</script>
app.blade.php which imports the example component
<head>
<script src="https://cdn.jsdelivr.net/npm/vue#2/dist/vue.js"></script>
</head>
<div id="app">
<x-example/>
#{{ text }}
</div>
<script>
var app = new Vue({
el: '#app',
data: {
text: #json($text),
}
});
</script>
if I move <x-example/> out <div id="app">, everything works fine, but it's not good for me.
<x-example/>
<div id="app">
#{{ text }}
</div>
What solutions can I find to use Laravel blades with VueJs source code?

I want to create nested element mounted vue.
However, vue-devtools can't detect components in vue component with v-pre. See desired code below:
HTML:
<body>
<div id="app">
<header></header>
<main id="main" v-pre>
something contents... <!-- NOT detected by vue-devtools -->
</main>
<footer></footer>
</div>
</body>
Attached JavaScript:
...
// About layouts
new Vue({
el: '#id',
components: {
Header,
Footer
}
});
// About main contents
new Vue({
el: '#main',
components: {
...
}
});
...
How do I solve this?
I have my input field in one div, and will have label in another div (as sidebar in my application). I want to update label in sidebar, as I type in input on first div.
I am happy to create second div a component if that's the way. I was reading online, and it was said we could use props to pass data to component. But I am not able to link input field to component. Please find my code as below:
var app = new Vue({
el: '#div1',
data: {
message: ''
}
})
Vue.component('testp', {
props: ['message'],
template: '<p>Message is: {{ message }}</p>'
})
var div2 = new Vue({
el: '#div2'
});
<!DOCTYPE html>
<html>
<head>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
<div id="div1">
<input v-model="message" placeholder="edit me">
</div>
<div id="div2">
<testp></testp>
</div>
</body>
</html>
As Pointed in Comment You have no reason to have two separate Vue instance and the First Answer is correct. But in some cases where you really need to have multiple Vue instances, you can actually use them in the following manner.
var app = new Vue({
el: '#div1',
data: {
message: ''
}
})
Vue.component('testp', {
props: ['message'],
template: '<p>Message is: {{ message }}</p>'
})
var div2 = new Vue({
el: '#div2',
computed: {
newMessage() {
return app.message;
}
},
});
Html
<!DOCTYPE html>
<html>
<head>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
<div id="div1">
<input v-model="message" placeholder="edit me">
</div>
<div id="div2">
<testp :message="newMessage"></testp>
</div>
</body>
</html>
Please observe the computed value newMessage is actually getting its value form a different Vue instance (app) and it is also reactive. Therefore whenever the value in first Vue instance changes, it is updated in another Vue instance.

Like I have pointed out in my comments, there is no reason for you to use two separate Vue instances. What you can do is simply wrap everything within an app container, e.g. <div id="#app">, and then instantiate your VueJS instance on that element instead.
Then, you can use v-bind:message="message" on the <testp> component to pass in the message from the parent. In this sense #div1 and #div2 are used entirely for markup/decorative purposes and are not used as VueJS app containers in your code.
Vue.component('testp', {
props: ['message'],
template: '<p>Message is: {{ message }}</p>'
});
var app = new Vue({
el: '#app',
data: {
message: ''
}
});
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<div id="app">
<div id="div1">
<input v-model="message" placeholder="edit me">
</div>
<div id="div2">
<testp v-bind:message="message"></testp>
</div>
</div>
While studying Vue By self-taught, I faced some problem.
First, I bind some component by new Vue ({el:" # id "}).
And when I bind root component <div id = "app"> by new Vue ({el:" # app "}),
It ruin what already was binding there.
My function and data in new Vue ({el:" # id "}) didn't work anymore.
Am I doing the wrong design?
If so, how should I approach the problem?
<html>
<head>
<script src="https://unpkg.com/vue#2.5.17/dist/vue.js"></script>
</head>
<body>
<div id="app">
<div id="comp-a">
<input type="text" v-model="message"/>
{{message}}
</div>
</div>
</body>
<script>
new Vue({
el : "#comp-a",
data : {
message : "message"
}
})
new Vue({
el : "#app"
})
</script>
You can use component.
reference: https://v2.vuejs.org/v2/guide/components.html
let comp_a=Vue.component('comp-a', {
data: function () {
return {
message: ""
}
},
template: ` <div><input type="text" v-model="message"/>
{{message}}</div>`
});
let app = new Vue({
el:"#app"
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<comp-a></comp-a>
</div>
If you want to component's html code in html area. template can point to by id. you can do following:
let comp_a=Vue.component('comp-a', {
data: function () {
return {
message: ""
}
},
template: "#comp-a"
});
let app = new Vue({
el:"#app"
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<comp-a></comp-a>
</div>
<template id="comp-a">
<div>
<input type="text" v-model="message"/>
{{message}}
</div>
</template>
VueJS does not work this way. You don't nest IDs. You could do this:
<html>
<head>
<script src="https://unpkg.com/vue#2.5.17/dist/vue.js"></script>
</head>
<body>
<div id="app">
</div>
<div id="comp-a">
{{message}}
</div>
</body>
<script>
new Vue({
el : "#app"
})
new Vue({
el : "#comp-a",
data : {
message : "message"
}
})
</script>
But even that approach has problems. You really should have only one matching VueJS area.
The only reason to have two is if you really have two applications running on the same html file. I have never seen a reason to do that.
I want to replace my project's first piece of vanilla JS with vue.
I try to get the hello world example working.
It works as stated, but when I nest the element in another element (these may be the wrong terms) it does not work.
My source code:
<!-- this works -->
<div id="app">
<p>${ message }</p>
</div>
<!-- but this doesn't for some reason -->
<div class="container">
<div id="app">
Nested ${ message }
</div>
</div>
Full code example.
The class="container" is needed for bootstrap.
EDIT:
I took the generated html and edited it down to just the bare minimum to show it not working.
See the result.
Wrap the container with
<div id="app"></div>
It should work that way
this works fine, the problem in your template is that you have two elements with id="app" so vue instance is initialized with the first element with id="app", then the second (the nested one) is never initialized
<html>
<head>
<script src="https://unpkg.com/vue"></script>
</head>
<body>
<!-- but this doesn't for some reason -->
<div class="container">
<div id="app">
Nested ${ message }
</div>
</div>
<script>
new Vue({
delimiters:['${', '}'],
el: '#app',
data: {
message: 'Hello Vue.js!'
}
})
</script>
</body>
</html>
You have 2 #app id but one vue instance. If you need two #app you should make two Vue instance. Instance 1 for #app1 and instance 2 for #app2. You can save theme in variables if you need to interact within theme:
<div id="app1">
<p>${ message }</p>
</div>
<div class="container">
<div id="app2">
Nested ${ message }
</div>
</div>
<script>
var app1 = new Vue({
delimiters:['${', '}'],
el: '#app1',
data: {
message: 'Hello Vue.js!'
}
});
var app2 = new Vue({
delimiters:['${', '}'],
el: '#app2',
data: {
message: 'Hello Vue.js!'
}
})
</script>

I am trying to use bootstrap color picker plugin with vue2. I read the following tutorial that shows how to do stuff like that.
Here is my component code:
<template>
<div class="input-group colorpicker-component">
<input type="text" value="#b8c7ce" class="form-control"/>
<span class="input-group-addon"><i></i></span>
</div>
</template>
<script>
export default {
mounted: function() {
$(this.$el).colorpicker()
},
}
</script>
https://itsjavi.com/bootstrap-colorpicker/
Color picker works fine If I call it directly from javascript like this:
$('#sidebar_font_color').colorpicker()
However when I do this
<color-picker></color-picker>
I get this in console:
[Vue warn]: Error in mounted hook: "TypeError: $(...).colorpicker is
not a function"
I am not making a full SPA app just using some vue2 with my application at various points. Any idea why it cant find that function?
Here's a minimal working example. Your error message indicates that you don't have the colorpicker code loaded when mounted runs, or possibly that jQuery is not loaded before the colorpicker code is.
new Vue({
el: '#app',
components: {
colorPicker: {
template: '#cp-template',
mounted() {
$(this.$el).colorpicker()
},
}
}
});
