This is my first time working with the html template tag. I don't know if I am doing it wrong but the output of the template is only showing the last item in the array. I've tried to loop through it and the foreach method but still only the last item shows. I know I am probably overriding the items as they are stacked on top of each other but I can't seem to figure it out Can someone point me in the right direction?
<div class="products-container">
<template>
<div class="product">
<img class="img">
<h2 class="item-title"></h2>
<h3 class="price"></h3>
</div>
</template>
</div>
const template = document.querySelector('template').content
const copyTemplate = document.importNode(template, true)
let shoppingList = [];
async function getData(data) {
const products = data.items.map(product => {
copyTemplate.querySelector('.item-title').textContent = product.title;
copyTemplate.querySelector('.price').textContent = product.price;
copyTemplate.querySelector('.img').src = product.image;
});
document.querySelector('.products-container').appendChild(copyTemplate);
shoppingList.push(products);
return products
}
I figured it out. I had to put the template and the copytemplate within the map function for it to work.
Sorry for the lengthy title, I have a feeling this is an oddly specific edge case not many people have to deal with.
Some background, I'm working on a webapp to track PC repairs for our shop. We have one currently, which we purchased and have access to the source code thanks to the author's method of distribution. Each repair is signified by a Work Order, all of which have notes. In the old app, the notes have the users name, the date it was posted, and the edit and delete buttons (if you are either the admin or the author) on the left, and the note on the right. If the user that posted the note changes when going down the list, it swaps them around, so the note is on the left and user is on the right, i.e.
user1 - note text
note text - user2
user3 - note text
user3 - note text
note text - user1
The old app did this with plain PHP, in a php file filled to the brim with echo statements. The new app I was working on has a laravel backend (to make use of things like Eloquent) with a Vue JS frontend (to assist with live updates in websockets). So on the Work Order page, there is a component for the list of notes, which takes the list of notes assigned to that Work Order as a prop, and iterates over all the notes with a v-for. I wanted to mimic the orientation switching feature from the previous setup. I can acheive the switch by setting up each note as a grid container, and applying either order-first or order-last to the column containing the user info. What I'm struggling with is trying to find a way to toggle which class is applied when the user changes.
At first I had a data attribute keeping track of the current class, so when the user changed I could check what the class was currently and switch it to the opposite. However, this caused an infinite render loop, as the entire list of notes would re-render whenever that attribute was changed. It did accomplish what I wanted to do visually, but it caused severe performance issues. Then I tried using refs, so when the user changed I could get the previous entry in the list from the refs array and examine its classes to see what order class it had to set the next elements order class appropriately. However this didn't work because the refs array would not be populated until the list was done rendering, and I needed to set the class as it rendered. I tried using a computed property, but it can't take arguments (i.e. the index of the array I was currently on to compare with index-1) and even if it could there is no way I could find to check the current cached value of that property while calculating the new one.
Here is the code I am working with for reference, currently with any of the previous approaches I tried removed, so currently no user switching happens.
<template>

</script>
noteType is there because we have two different types of notes, one that a customer can see, and one that only techs can see.
Is there something obvious I'm missing, have I just architected this thing wrong, am I trying to do something impossible? Any assistance would be greatly appreciated, I'm at the end of my rope here with this one.
I ended up figuring out a solution to this, not sure if its the best one but here goes.
Basically, I maintain an array parallel to the notes array that determines which order- class each array index should have. As it is dependent on the notes attribute, I make it a computed property, so that I can use the notes attribute and it automatically updates when the notes list changes. The file now looks like this (with some code related to posting new notes and editing existing ones removed for clarity)
<template>
<ul class="list-unstyled">
<li class="row no-gutters mb-2" v-bind:key="index" v-for="(note, index) in this.notes">
<div class="col-md-1 d-flex flex-column mx-md-3" :class="noteOrders[index]">
<div class="text-center p-0 m-0">{{note.noteuser}}</div>
</div>
<div class="col-md-10">
<div class="card m-2">
<div class="card-body p-2">
{{ note.thenote }}
</div>
</div>
</div>
</li>
</ul>
</template>
<script>
export default {
props: ['initialnotes'],
data () {
return {
notes: this.initialnotes,
}
},
computed: {
noteOrders () {
return this.getNoteOrders(this.notes)
}
},
methods: {
getNoteOrders(notes) {
let noteOrders = []
notes.forEach((note,index) =>{
if (index === 0) {
noteOrders[index] = 'order-first'
} else if (note.noteuser !== notes[index-1].noteuser) {
if (noteOrders[index-1] === 'order-first') {
noteOrders[index] = 'order-last'
} else {
noteOrders[index] = 'order-first'
}
} else {
noteOrders[index] = noteOrders[index-1]
}
})
return noteOrders
}
}
}
</script>
There may very well be better solutions and I encourage anyone who happens upon this to post theirs if they have one, but as I found a solution that works for me I decided to post it for anyone else running into the same issue.
My code looks something like
var publishedDate = Convert.ToDateTime(node.GetProperty("publishedDate").Value);
string image = Umbraco.Content(node.Id).GetPropertyValue("postImage").src;
string categories = #node.GetProperty("categories").Value.Replace(",", ", ");
<div class="column">
<img class="post-image" src="#image">
<div class="post-details" data-equalizer-watch>
<h5 class="post-category">#categories</h5>
<h2 class="post-title">#node.Name</h2>
<h6 class="post-date">#string.Format("{0:MMMM dd, yyyy}", publishedDate)</h6>
</div>
</div>
and when I view the image source in Chrome using developer tools, the image src will end up looking like
src="/media/8354/collegis_blogs_design_jr_7-23_15_news.jpg?1499808181609"
the appended string after the jpg is causing the image to error out. This does not occur in Internet Explorer since no string gets appended. Anyone have any idea why this could be occuring?
thanks,
Depending on which version of Umbraco you are using I would get the media path like this:
for v7.6 and above
string imageUrl = Model.Content.GetPropertyValue<IPublishedContent>("headerImage").Url;
for v7.5x and below
UmbracoHelper uHelper = new UmbracoHelper(UmbracoContext.Current);
string mediaUrl = "";
if (CurrentPage.HasValue(propertyName))
{
var mediaItem = uHelper.Media(CurrentPage.propertyName.ToString());
mediaUrl = mediaItem.umbracoFile;
}
return mediaUrl;
See my blog post about it and for how to do it from a controller.

I have a case where in my Vue.js with webpack web app, I need to display dynamic images. I want to show img where file name of images are stored in a variable. That variable is a computed property which is returning a Vuex store variable, which is being populated asynchronously on beforeMount.
<div class="col-lg-2" v-for="pic in pics">
<img v-bind:src="'../assets/' + pic + '.png'" v-bind:alt="pic">
</div>
However it works perfectly when I just do:
<img src="../assets/dog.png" alt="dog">
My case is similar to this fiddle, but here it works with img URL, but in mine with actual file paths, it does not work.
What should be correct way to do it?
I got this working by following code
getImgUrl(pet) {
var images = require.context('../assets/', false, /\.png$/)
return images('./' + pet + ".png")
}
and in HTML:
<div class="col-lg-2" v-for="pic in pics">
<img :src="getImgUrl(pic)" v-bind:alt="pic">
</div>
But not sure why my earlier approach did not work.
Here is a shorthand that webpack will use so you don't have to use require.context.
HTML:
<div class="col-lg-2" v-for="pic in pics">
<img :src="getImgUrl(pic)" v-bind:alt="pic">
</div>
Vue Method:
getImgUrl(pic) {
return require('../assets/'+pic)
}
And I find that the first 2 paragraphs in here explain why this works? well.
Please note that it's a good idea to put your pet pictures inside a subdirectory, instead of lobbing it in with all your other image assets. Like so: ./assets/pets/
You can try the require function. like this:
<img :src="require(`#/xxx/${name}.png`)" alt class="icon" />
The # symbol points to the src directory.
source: Vue URL transfrom rules
There is another way of doing it by adding your image files to public folder instead of assets and access those as static images.
<img :src="'/img/' + pic + '.png'" v-bind:alt="pic" >
This is where you need to put your static images:
Your best bet is to just use a simple method to build the correct string for the image at the given index:
methods: {
getPic(index) {
return '../assets/' + this.pics[index] + '.png';
}
}
then do the following inside your v-for:
<div class="col-lg-2" v-for="(pic, index) in pics">
<img :src="getPic(index)" v-bind:alt="pic">
</div>
Here's the JSFiddle (obviously the images don't show, so I've put the image src next to the image):
https://jsfiddle.net/q2rzssxr/
Vue.js uses vue-loader, a loader for WebPack which is set up to rewrite/convert paths at compile time, in order to allow you to not worry about static paths that would differ between deployments (local, dev, one hosting platform or the other), by allowing you to use relative local filesystem paths. It also adds other benefits like asset caching and versioning (you can probably see this by checking the actual src URL being generated).
So having a src that would normally be handled by vue-loader/WebPack set to a dynamic expression, evaluated at runtime, will circumvent this mechanism and the dynamic URL generated will be invalid in the context of the actual deployment (unless it's fully qualified, that's an exception).
If instead, you would use a require function call in the dynamic expression, vue-loader/WebPack will see it and apply the usual magic.
For example, this wouldn't work:
<img alt="Logo" :src="logo" />
computed: {
logo() {
return this.colorMode === 'dark'
? './assets/logo-dark.png'
: './assets/logo-white.png';
}
}
While this would work:
<img alt="Logo" :src="logo" />
computed: {
logo() {
return this.colorMode === 'dark'
? require('./assets/logo-dark.png')
: require('./assets/logo-white.png');
}
}
I just found out about this myself. Took me an hour but... you live, you learn, right? 😊
I also hit this problem and it seems that both most upvoted answers work but there is a tiny problem, webpack throws an error into browser console (Error: Cannot find module './undefined' at webpackContextResolve) which is not very nice.
So I've solved it a bit differently. The whole problem with variable inside require statement is that require statement is executed during bundling and variable inside that statement appears only during app execution in browser. So webpack sees required image as undefined either way, as during compilation that variable doesn't exist.
What I did is place random image into require statement and hiding that image in css, so nobody sees it.
// template
<img class="user-image-svg" :class="[this.hidden? 'hidden' : '']" :src="userAvatar" alt />
//js
data() {
return {
userAvatar: require('#/assets/avatar1.svg'),
hidden: true
}
}
//css
.hidden {display: none}
Image comes as part of information from database via Vuex and is mapped to component as a computed
computed: {
user() {
return this.$store.state.auth.user;
}
}
So once this information is available I swap initial image to the real one
watch: {
user(userData) {
this.userAvatar = require(`#/assets/${userData.avatar}`);
this.hidden = false;
}
}
Here is Very simple answer. :D
<div class="col-lg-2" v-for="pic in pics">
<img :src="`../assets/${pic}.png`" :alt="pic">
</div>
<img src="../assets/graph_selected.svg"/>
The static path is resolved by Webpack as a module dependency through loader.
But for dynamic path you need to use require to resolve the path. You can then switch between images using a boolean variable & ternary expression.
<img :src="this.graph ? require( `../assets/graph_selected.svg`)
: require( `../assets/graph_unselected.svg`) " alt="">
And of course toggle the value of the boolean through some event handler.
<div
v-for="(data, i) in statistics"
:key="i"
class="d-flex align-items-center"
>
<img :src="require('#/assets/images/'+ data.title + '.svg')" />
<div class="ml-2 flex-column d-flex">
<h4 class="text-left mb-0">{{ data.count }}</h4>
<small class="text-muted text-left mt-0">{{ data.title }}</small>
</div>
</div>
You can use try catch block to help with not found images
getProductImage(id) {
var images = require.context('#/assets/', false, /\.jpg$/)
let productImage = ''
try {
productImage = images(`./product${id}.jpg`)
} catch (error) {
productImage = images(`./no_image.jpg`)
}
return productImage
},
I also faced this problem.
Try it:
computed {
getImage () {
return require(`../assets/images/${imageName}.jpg`) // the module request
}
}
Here is a good article that clarifies this:
https://blog.lichter.io/posts/dynamic-images-vue-nuxt/
Tried all of the answers here but what worked for me on Vue2 is like this.
<div class="col-lg-2" v-for="pic in pics">
<img :src="require(`../assets/${pic.imagePath}.png`)" :alt="pic.picName">
</div>
As I am using Gridsome, this way worked for me.
**I also used toLowerCase() method
<img
:src="
require(`#/assets/images/flags/${tournamentData.address.country_name.toLowerCase()}.svg`)
"
/>
well the best and easiest way that worked for me was this of which i was fetching data from an API..
methods: {
getPic(index) {
return this.data_response.user_Image_path + index;
}
}
the getPic method takes one parameter which is the name of the file and it returns the absolute path of the file maybe from your server with the file name simple...
here is an example of a component where i used this:
<template>
<div class="view-post">
<div class="container">
<div class="form-group">
<label for=""></label>
<input type="text" class="form-control" name="" id="" aria-describedby="helpId" placeholder="search here">
<small id="helpId" class="form-text user-search text-muted">search for a user here</small>
</div>
<table class="table table-striped ">
<thead>
<tr>
<th>name</th>
<th>email</th>
<th>age</th>
<th>photo</th>
</tr>
</thead>
<tbody>
<tr v-bind:key="user_data_get.id" v-for="user_data_get in data_response.data">
<td scope="row">{{ user_data_get.username }}</td>
<td>{{ user_data_get.email }}</td>
<td>{{ user_data_get.userage }}</td>
<td><img :src="getPic(user_data_get.image)" clas="img_resize" style="height:50px;width:50px;"/></td>
</tr>
</tbody>
</table>
</div>
</div>
</template>
<script>
import axios from 'axios';
export default {
name: 'view',
components: {
},
props:["url"],
data() {
return {
data_response:"",
image_path:"",
}
},
methods: {
getPic(index) {
return this.data_response.user_Image_path + index;
}
},
created() {
const res_data = axios({
method: 'post',
url: this.url.link+"/view",
headers:{
'Authorization': this.url.headers.Authorization,
'content-type':this.url.headers.type,
}
})
.then((response)=> {
//handle success
this.data_response = response.data;
this.image_path = this.data_response.user_Image_path;
console.log(this.data_response.data)
})
.catch(function (response) {
//handle error
console.log(response);
});
},
}
</script>
<style scoped>
</style>
I encountered the same problem.
This worked for me by changing '../assets/' to './assets/'.
<img v-bind:src="'./assets/' + pic + '.png'" v-bind:alt="pic">
The image needs to be transcribed.
What worked for me is putting the images in public folder. i.e public/assets/img
Dynamic Image Tag:
<div v-for="datum in data">
<img
class="package_image"
style="max-width:200px;"
alt="Vue logo"
:src="`./assets/img/${datum.image}`"
>
<div>
I have a solution you may want to try.
Define a method like below
methods: {
getFlagImage(flag){
return new URL('/resources/img/flags/'+flag+'.png', import.meta.url);
},
}
then images can be called with the established for loop
<li :class=" 'nav-item', {'active': language === key} " v-for="(value,
key) in locals" :key="value ">
<a class="dropdown-item" #click="switchLanguageTo(key)">
<img :src="getFlagImage(key)" /> {{value}}
</a>
</li>
I think I found the best solution to this problem by accident!
The only thing you have to do is to start addressing from the root.
Doesn't work
<img :src="'../assets/' + pic + '.png">
Work:
<img :src="'src/assets/' + pic + '.png">
As of today, working with VUE 3 + Typescript & composition API, what I have done is wrap require function in try catch to handle crash.
computed: {
getImage() {
let imgSrc = "";
try {
imgSrc = require(`../assets/weather-widget-icons/ww-icon-${this.weatherForecast.main.toLowerCase()}.svg`);
} catch (error) {
console.error(`Image '../assets/weather-widget-icons/ww-icon-${this.weatherForecast.main.toLowerCase()}.svg' not found!`);
}
return imgSrc;
}
}
and call this function in image tag:
<div class="weather-icon">
<img :src="getImage" :alt="weatherForecast.main" />
</div>
I am trying to remove a single document from the collection in over server side with Meteor.methods by passing _id of object ,but it is not removing object , also tried other fields in that document but no go.
I have also tried FoodCategory.remove(removeID) ; that is also not working.
File 1 - displayCategorySection.html
<template name="categoryDisplaySection">
<div class="row categoryDisplay">
<div class="col-md-10 col-lg-10 ">
{{Category}}
</div>
<div class="col-md-2 col-lg-2 pull-right">
<i class="fa fa-minus-square"></i>
</div>
</div>
<div class="row ">
<div class="col-md-12 col-lg-12 identity">
{{_id}}
</div>
</div>
</template>
In the .JS file I am passing this _id to Meteor method deleteFoodCategory
File 2 - categoryDisplaySection.js
Template.categoryDisplaySection.events({
'click .fa-minus-square':function(evt,tmpl)
{
var remove_id = tmpl.$(".identity").text();
alert(remove_id);
/*****Server side call for document remove *****/
Meteor.call("deleteFoodCategory",remove_id,
function(error,result)
{ alert(result); });
}
});
Server Side File 3 - FoodCategorySection.js contain deleteFoodCategory method
Meteor.methods({
deleteFoodCategory: function(removeID)
{
return FoodCategory.remove({
'_id' : removeID
},
function(error,id)
{
if(id) { return id;} else { return error; }
});
}
});
Code is working correctly if I put _id like "RAEnLfomeqctuonnE" in place of variable removeID. I tried various options like '_id' or just _id without quotes , unable to figure out problem.Please take a look
Fetching the document _id from a div text is overkill, you could use the current data context instead :
Template.categoryDisplaySection.events({
"click .fa-minus-square": function(evt,tmpl){
var removeId = this._id;
alert(removeId);
Meteor.call("deleteFoodCategory", removeId);
});
In your Meteor method, you can simply pass the _id to Collection.remove :
Meteor.methods({
deleteFoodCategory: function(removeId){
return FoodCategory.remove(removeId);
}
});
Answer provided by saimeunt is also working correctly as far as original problem is concern , there is need to use .trim function with remove_id variable
File 2 - categoryDisplaySection.js
Template.categoryDisplaySection.events({
"click .fa-minus-square": function(evt,tmpl){
var remove_id = tmpl.$(".identity").text();
/**This line needed to be added**/
removeId = remove_id.trim();
alert(removeId);
/*****Server side call for data insert *****/
Meteor.call("deleteFoodCategory",removeId);
})
but as #saimeunt has said fetching the document _id from a div text is overkill,so using this_id from now on
