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.

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>
The Sheety API is great but I cannot make it work with Vue.
The only included example uses jQuery with handlebars.js which, like vue.js, uses double mustache syntax that collides.
<html>
<head>
<title>UK Theme Parks</title>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/4.0.12/handlebars.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$.getJSON('https://api.sheety.co/uk-theme-parks', function(data) {
var template = Handlebars.compile($('#item-template').html())
$('#items').html(template(data))
})
})
</script>
<script id="item-template" type="text/x-handlebars-template">
<ul>
{{#each this}}
<li>{{name}}</li>
{{/each}}
</ul>
</script>
</head>
<body>
<div id="items">Loading theme parks...</div>
</body>
</html>
Is there a way to make this example work inside the Vue component? Most preferably, to make it work without having to import the handlebars.js or jQuery?
Please mind that I am an exploratory designer, not a well-versed js coder, so I would greatly appreciate a working example :)
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>
I am using browserify and i want to use bxslider. When i had all the templates in a single file (index.html), it was working. Now i am using browserify to build it so i have vue components. I want to use bx slider in a vue component.
slider.vue
<ul class="bxslider">
<li>
<img src="img/thumb-01.jpg"/>
</li>
</ul>
index.html
<link href="plugins/bxslider/jquery.bxslider.css" rel="stylesheet" />
<div id="app"></div>
<!-- scripts -->
<script src="plugins/jQuery/jQuery-2.2.0.min.js"></script>
<script src="plugins/bxslider/jquery.bxslider.min.js"></script>
<script src="dist/build.js"></script>
<script>
$(document).ready(function(){
$('.bxslider').bxSlider();
});
</script>
I couldn't get the bxslider, i try to use it as a function in a component, alse try to use it in a seperate file. Any suggestions please?
The problem is that $(document).ready() is executed before the vue.js code. You need to replace this code
$(document).ready(function(){
$('.bxslider').bxSlider();
});
with
$(document).ready(function(){
setTimeout(function(){
$('.bxslider').bxSlider();
},100);
});
Im trying to run this plugin
https://github.com/jzaefferer/jquery-treeview
In clear html it works, so it means the problem is in my mvc code.
I have following code
<!-- TREEVIEW Plugin -->
<link href="/Content/jquery-treeview/jquery.treeview.css" rel="stylesheet" type="text/css" />
<script src="/Content/jquery-treeview/jquery-1.2.6.min.js" type="text/javascript"></script>
<script src="/Content/jquery-treeview/jquery.treeview.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$("#treeview ul").treeview();
});
</script>
the link addresses are okay, because they are not underlined and i checked the path manually. In clear HTML the plugin works. I also tried
#Scripts.Render("~/Content/jquery-treeview/jquery-1.2.6.min.js")
or
#Url.Content("~/Content/jquery-treeview/jquery-1.2.6.min.js")
At it seems same (not working). Where is the problem ?
But this code works, so JQuery is loaded.
$(document).ready(function () {
alert("ready!");
});
HTML Code
<div id="treeview">
<ul>
<li>Category
<ul><li>SubCategory</li></ul>
</li>
</ul>
</div>
Mystery revealed, in Shared/_Layout.cshtml JQuery was also included by default so the solution was comment it out :-)
