handlebars dynamic partial names - dynamic

i have a component in my example an accordion and i want to reuse it with different templates inside it's content-area.
what i have achieved is to create the accordion.
<div class="c_accordion">
{{#each data}}
<div class="c_accordion__item">
<h3 class="c_accordion__headline">{{this.title}}</h3>
<div class="c_accordion__content">
{{../template}} <-- renders [object object]
{{> ('../template') data=this.content}} <-- there i want to render diffrent templates
{{> list data=this.content}} <-- this works without problems
</div>
</div>
{{/each}}
</div>
And now i want to render different templates insinde my accordion (for example a list partial)
{{> accordion template=list data=about.services}}
But i always get an error "Warning: The partial undefined could not be found Use"
I tried it also with the helper lookup, but also the same result with an error.
Generally is that the correct way or there are others approaches to solve this problem??
I'm using grunt-assemble to build static sites. this is the handlbars version ## v4.0.5 - November 19th, 2015

ok i found a solution ;)
based on this
assemble - Render a list of strings as Handlebars partial
//insert the accordion
{{> accordion partial="list" data=about.services}}
//accordion.hbs
<div class="c_accordion">
...
{{dynamicPartial ../partial this.content}}
...
</div>
//helper dynamicPartial
module.exports.register = function (Handlebars, context) {
Handlebars.registerHelper('dynamicPartial', function(name, data) {
var partial = Handlebars.partials[name];
var template = Handlebars.compile(partial);
var output = template({"data": data});
return new Handlebars.SafeString(output);
})
};
//list.hbs
<ul>
{{#each data}}
<li>{{this}}</li>
{{/each}}
</ul>

v-on:click not working - dynamically added html element

I am trying to get all images for a category using Vue
<div class="col-md-12 col-sm-2 p-2">
<a v-on:click="onCategoryManageImageClick($event)" data-target="#location-
category-images">
</span>
</a>
</div>
So the event onCategoryManageImageClick ($event) does not work, if I am adding a html block and then click on get image button.
this is index.js
methods:{
onImagesTabClick(){
this.$root.$emit('activated-tab:location-images');
},
onCategoriesTabClick(){
window.j1App.eventBus.$emit("j1-location-image-list:shown");
},
onCategoryManageImageClick: function(event) {console.log('working event..');
event.preventDefault();
window.j1App.eventBus.$emit("j1-location-category-image-
list:shown",event.currentTarget.id);
}
}
So basically it need to to work like we do in jQuery
$(document).on('click',function{
})
So it works either page load or if adding any new html element on DOM. same I want in Vue.
You cannot alter the Vue template outside of Vue. That won't work. Vue compiles the template once when starting up and adds the event listeners to the rendered elements. If you add elements afterwards, Vue will not know about them.
The correct way of doing this would be to add those new elements in Vue.
<div
class="col-md-12 col-sm-2 p-2"
v-for="item in items"
:key="item.id"
>
<a
v-on:click="onCategoryManageImageClick($event, item)"
data-target="#location-category-images"
>
</a>
</div>
See https://v2.vuejs.org/v2/guide/list.html for documentation. In this case you need the items array variable in data and add more array elements to it, if you need more links.
Try raplacing your a tag with p
<div class="col-md-12 col-sm-2 p-2">
<p v-on:click="onCategoryManageImageClick" data-target="#location-
category-images">
</p>
</div>

Why isn't the value of the object properties inserted here?

I started learning vue yesterday and I'm now fiddling around on the CLI3.
Currently I'm trying out the different approaches to inserting data into my markup.
Here, I basically want to make a "list of Lists".
This here is list1:
<template>
<div>
<ul v-for="item in items">
<li :text="item"></li>
</ul>
</div>
</template>
<script>
export default{
name:"list1",
data() {
return {
items: {
item1 : "itemA",
item2 : "itemB",
item3 : "itemC"
}
}
}
}
</script>
This is the list of lists:
<template>
<div>
<h1>All my stuff in a biiig list!</h1>
<listOfLists />
</div>
</template>
<script>
import listOfLists from '#/components/listOfLists.vue'
export default {
name: 'myComplexView.vue',
components: {
listOfLists
}
}
And this is inserted into myComplexView.vue inside views (im working with routing as well, though it doesnt work perfectly yet as you will see on the screenshot), which you can see here:
<template>
<div>
<h1>All my stuff in a biiig list!</h1>
<listOfLists />
</div>
</template>
<script>
import listOfLists from '#/components/listOfLists.vue'
export default {
name: 'myComplexView.vue',
components: {
listOfLists
}
}
</script>
This is the result Im getting:

Since routing doesnt work correctly yet, I had to enter the url into the browser manually. Fortunately, the site at least loaded that way as well, so I can tackle these problems bit by bit ^^
As you can see, the data was iterated over correctly by the v-for.
However, the data wasn't inserted in the text attribute of the li elements.
I'm a bit clueless about the cause though.
Maybe I'm not binding to the correct attribute? Vue is using its own naming conventions, based off standard html and jquery as far as I understood.
You've got this in your template:
<li :text="item"></li>
This will bind the text attribute to the value, outputting, e.g.:
<li text="itemA"></li>
You should be able to see this in the developer tools. In the picture you posted you hadn't expanded the relevant elements so the attributes can't be seen.
I assume what you want is to set the content. For that you'd either use v-text:
<li v-text="item"></li>
or more likely:
<li>{{ item }}</li>
Either of these will output:
<li>itemA</li>
On an unrelated note, I would add that this line will create multiple lists:
<ul v-for="item in items">
It's unclear if that's what you want. You're going to create 3 <ul> elements, each with a single <li> child. If you want to create a single <ul> then move the v-for onto the <li>.

Using plain JS in Vue.js Component

So, I want to create a navbar and rather than re-invent the wheel, I am using some public code to speed up my MVP dev.
Essentially, I am using this nav-bar code - https://codepen.io/PaulVanO/pen/GgGeyE.
But I am not sure of how I can implement jquery part within my Vue code (I have made a component, copied over html and css, now just need to integrate the jquery functionality within it.)
Here is the Jquery code I need to integrate.
$('#toggle').click(function() {
$(this).toggleClass('active');
$('#overlay').toggleClass('open');
});
It would be really thankful if anyone could help me accomplish with this.
Assuming you have your markup (html and css) as part of one component, getting the toggle to add/remove a class would be really simple, you just need to have a method toggle the active state and a data property to keep the data. An example would be better, so here it goes.
In your component object:
{
data() {
return {
isActive: false
}
},
methods: {
toggleMenu(){
this.isActive = !this.isActive
}
}
}
In your markup you need this
<div class="button_container" id="toggle" :class="{'active': isActive}" #click="toggleMenu">
<span class="top"></span>
<span class="middle"></span>
<span class="bottom"></span>
</div>
------------------------------------
<div class="overlay" id="overlay" :class="{'open': isActive}">
<nav class="overlay-menu">
<ul>
<li >Home</li>
<li>About</li>
<li>Work</li>
<li>Contact</li>
</ul>
</nav>
That should get you going, just note i used the shorthand form for v-on and for v-bind
EDIT:
Here's also a link to an updated pen with the whole example

How to allow nested accordions but manage top level as accordion (and not collapsable) with materializecss?

I'm using nested accordions with Materializecss. I want to be able to have nested accordions, but to let each level to only have 1 item of the accordion opened (as of data-collapsible='accordion').
I can't get it to work: if I set data-collapsible='accordion' I cannot open nested accordions, and if I set data-collapsible='collapsible', I can open any number of items per accordion.
Any workaround?
Thanks!
If you are managing the inner elements of the collapsibles dinamically, then you need to "initialize" them using a jquery method included in "materialize.js". This is written in the "materializecss" documentation here.
I'll provide a practical example.
Given the next HTML:
...
<ul class="collapsible" data-collapsible="accordion">
<li>
<div class="collapsible-header">
My nested collapsible
</div>
<div class="collapsible-body">
<ul class="nested collapsible" data-collapsible="accordion">
<!-- No data initially -->
</ul>
</div>
</li>
<li>
<div class="collapsible-header">Second</div>
<div class="collapsible-body">
<p>Normal data...</p>
</div>
</li>
</ul>
...
I suppose the problem comes because you are appending data into the ".nested" div, and it's not working as an accordion as expected.
You should then do something like:
// ... Your handler code ...
// ... Data appended into $('.nested')
$('.nested').collapsible({accordion: true});
// ...
The {accordion: true} option is not mandatory, as it will be treated as an accordion by default.
It should work in this case. Good luck.

Dojo loading templated widget into data-dojo-type

I've created a very simple HTML templated widget.
<div class="tool">
<a href="" id="freehand">
<i class="flaticon-writing9"></i>
</a>
</div>
<div class="tool">
<a href="" id="polygon">
<i class="flaticon-constellation"></i>
</a>
</div>
My widget declaration looks like this:
define([
"dojo/_base/declare",
"dijit/_WidgetBase",
"dijit/_TemplatedMixin",
"dojo/text!./templates/DrawingToolsWidget.html",
"dojo/parser",
"dojo/ready"
],
function(declare, _WidgetBase, _TemplatedMixin, template, parser, ready) {
return declare("DrawingToolsWidget",[_WidgetBase, _TemplatedMixin], {
templateString: template,
constructor: function() {
console.log(this);
}
});
ready(function(){
parser.parse();
});
}
);
I try to attach it to a point in my main DOM with a data-dojo-type attribute:
<div id="drawing-tools-container" data-dojo-type="DrawingToolsWidget"></div>
But I keep getting a generic dojo/parser::parse() error Error {} which is completely useless for debugging.
My directory structure is: /index.html(main DOM) /app/DrawingToolWidget/templates/DrawingToolsWidget.html(template) /app/DrawingToolWidget/DrawingToolWidget.js(declaration)
I've also tried to attach "app/DrawingToolWidget/DrawingToolWidget" just in case it wanted the path to the widget declaration. Nope.
What am I doing wrong? Why is it so hard just to attach a fragment of markup to the DOM?
Your template is invalid because you can only have 1 root element. I'm not sure if that's the main problem, but this might solve certain things. A quote from the documentation:
Note that when you define a template, it can only have one root
node definition ( just like with XML documents). Multiple nodes at the
top level is not allowed.
The article: http://dojotoolkit.org/documentation/tutorials/1.9/templated/
A working template would be:
<div>
<div class="tool">
<a href="" id="freehand">
<i class="flaticon-writing9"></i>
</a>
</div>
<div class="tool">
<a href="" id="polygon">
<i class="flaticon-constellation"></i>
</a>
</div>
</div>
The working example can be found here.
About your debugging problem, do you use Google Chrome? When encountering an error, you should try to close and open the developer tools/console, if you do that, there should be a small arrow next to the Error, for example:
As you can see here, there are 2 arrows, the left one gives you the stacktrace, while the right one (almost at the end of the error line), will give you detailed information about the error (if you click/expand it).
