I have a very simple local setup for VueJS and am having problems running a simple example that shows how raw HTML can be output. I'm not including link to JS Fiddle because I want to make it work on local setup only, and sometimes my examples work on JS Fiddle but not on local machine.
Anyway, here's the html code:
<html>
<head>
<script src="https://unpkg.com/vue"></script>
<script src="app.js"></script>
</head>
<body>
<div id="app">
<!-- Doesn't work! -->
<p>{{ link }}</p>
<!-- This works! -->
<p v-html>{{ link }} </p>
</div>
</body>
</html>
And here's my app.js file:
window.addEventListener('load', function(){
new Vue({
el: '#app',
data: {
link: 'Google'
}
});
});
Now when I load the window, I get twice the following error:
[Vue warn]: Property or method "link" is not defined on the instance but referenced during render. Make sure to declare reactive data properties in the data option. (found in <Root>).
Any idea where I'm going wrong?
Can you try this one and see if it works as required. I moved the scripts after the body.
<html>
<head>
</head>
<body>
<div id="app">
<!-- Doesn't work! -->
<p>{{ link }}</p>
<!-- This works! -->
<p v-html>{{ link }} </p>
</div>
</body>
<script src="https://unpkg.com/vue"></script>
<script src="app.js"></script>
</html>

But I am getting this as output not sure why.
Why productName and productDescription are not appearing as string values?
index.js:
const app = Vue.createApp({
data() {
return {
productName: 'Book a Cruise to the Moon',
productDescription: 'Cruise to the moon in our luxurious shuttle. Watch the astronauts working outside the International Space Station.',
// additional properties later
};
},
});

I tested your code on my computer and it worked for me.
Make sure the file path is correct and try again.
I just copied and pasted.
I'm trying to setup basic prototype web pages to test UX design in code. And want to recycle html files such as left navigation. Trying to use Vue to do this so that I can also learn Vue. I do not have access to the artifactory (company policy). So I cannot use things other than this http vue loader package that I found. So far, I was able to add external vue which is comp-nav. But from here, I want to pass title="Service" from index.html to comp-vue. How do I do that? Any help would be great! BTW, using Apache2 that came with mac to run.
index.html
<!DOCTYPE html>
<html lang="en">
<title>App</title>
<!-- Vue2 -->
<!-- from https://github.com/FranckFreiburger/http-vue-loader -->
<head>
<script src="https://unpkg.com/vue"></script>
<script src="https://unpkg.com/http-vue-loader"></script>
</head>
<body>
<div id="app">
<comp-nav title="Service"></comp-nav>
</div>
<script type="text/javascript">
var app = new Vue({
el: '#app',
components: {
'comp-nav': httpVueLoader('components/comp-nav.vue')
}
});
</script>
</body>
</html>
components/comp-nav.vue
<template>
<div id="nav">
<div class="nav-header">
<div class="header-title"><a>{{ title }}</a></div>
<div class="header-close">U</div>
</div>
<div class="nav-body">
<ul>
<li>Link 1</li>
<li>Link 2</li>
<li>Link 3</li>
</ul>
</div>
</div><!-- #nav -->
</template>
Based on the example from the docs, you could define a component prop in comp-nav.vue:
<template>
<div class="header-title">{{ title }}</div>
</template>
<script>
module.exports = {
props: ['title']
}
</script>
I'm new to Vue.js and trying to test semantic binding. I have Vue.js in the same directory as my test page but I get a Vue warning of "Cannot find element: #growler". Am I doing this correct?
html
<head>
<title>
Growler
</title>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css">
<link rel="stylesheet" href="style.css">
<script src="vue.js"></script>
<script src="app.js"></script>
</head>
<body>
<div id="growler"></div>
<h2> {{ appName }} </h2>
</body>
app.js
var growler = new Vue({
el: '#growler',
data: {
appName: 'Growler'
}
});
Your HTML-markup is wrong.
The closing div tag has to be after the h2, otherwise the variable appName will not be found.
<div id="growler">
<h2> {{ appName }} </h2>
</div>
The error "Cannot find element: #growler" probably appears, because you include app.js in the head. Either move it downwards before the closing body tag or add some window.onload-condition to it to make sure, the JS will be executed after rendering the inital page.
app.js script must be below the application div
Also you must put the h2 tag inside the #glower div
Because the vue application glower working only inside #glower div
<div id="growler">
<h2> {{ appName }} </h2>
</div>
<head>
<title>
Growler
</title>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css">
<link rel="stylesheet" href="style.css">
</head>
<body>
<div id="growler">
<h2> {{ appName }} </h2>
</div>
<script src="vue.js"></script>
<script src="app.js"></script>
</body>
There was a error in your HTML.
In my vue-bootstrap application I would like to use hidden input file control. When I use the standard input component it works (Load 1). If i try to do the same with the reactive component form vue-bootstrap library it does not work (Load 2). I would appreciate any hints what I might be doing wrong.
app = new Vue({
el: "#app",
data: {
files: '',
}
})
<html>
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css" >
<script src="https://unpkg.com/vue"></script>
<script src="https://unpkg.com/bootstrap-vue#latest/dist/bootstrap-vue.js"></script>
</head>
<body>
<div id="app">
<div>
<b-button #click="$refs.fileInput1.click()"> Load 1</b-button>
<input type="file" ref="fileInput1" style="display:none;"/>
</div>
<div>
<b-button #click="$refs.fileInput2.click()"> Load 2</b-button>
<b-form-file v-model="files" style="display:none;" ref="fileInput2" />
</div>
</div>
</body>
</html>
The $refs.fileInput2 here is referring to the Vue component, not really the input element, which is actually wrapped inside a div (you could see it if you inspect the rendered element). So one thing you could do (although it's ugly and not recommended, you should at least move this to the methods section):
app = new Vue({
el: "#app",
data: {
files: '',
}
})
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css">
<script src="https://unpkg.com/vue"></script>
<script src="https://unpkg.com/bootstrap-vue#latest/dist/bootstrap-vue.js"></script>
<div id="app">
<div>
<b-button #click="$refs.fileInput1.click()"> Load 1</b-button>
<input type="file" ref="fileInput1" style="display:none;" />
</div>
<div>
<b-button #click="$refs.fileInput2.$el.querySelector('input[type=file]').click()"> Load 2</b-button>
<b-form-file v-model="files" style="display:none;" ref="fileInput2" />
</div>
</div>
Although I would say you should just use the native file input element since you are hiding the <b-form-file/> anyway.
It's working fine.You may check the below fiddle.

<b-form-file style="display:none;" v-model="file2" choose-label="Attachment2"></b-form-file>

I am in learning phase of vue.js and here is my index.html code as follows:
<html>
<head>
<link rel="stylesheet" href="index.css">
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
<div id="app">
<ul>
<todo-item></todo-item>
</ul>
</div>
<script src="index.js"></script>
</body>
</html>
and code of index.js is as follows:
Vue.component('todo-item', {
template: '<li>Todo 1</li><li>Todo 2</li>'
})
var app = new Vue({
el: '#app'
})
now in the output, I am getting only one <li>Todo 1</li> not the second Todo 2.
Can anyone let me know why it is happening?
In case I repeat the <todo-item></todo-item> in index.html then it is repeating Todo 1, should not it display Todo 2 after Todo 1?
I have gotten the answer, It was happening because
Component template should contain exactly one root element.
and I was using two <li> in the same template without a root element.
So I have changed in the template as
template: '<ul><li>This is a todo</li><li>Another work</li></ul>'
and removed <ul> from index.html. It is working fine now.
