I have below html:
<li>
<div class="w3l_banner_nav_right_banner1" style="background:url('./assets/images/2.jpg') no-repeat 0px 0px;">
<h3>Make your <span>food</span> with Spicy.</h3>
<div class="more">
Shop now
</div>
</div>
</li>
Problem:
I want to replace image url /assets/images/2.jpg with dynamic variable like {{ article.uri }}.
I tried with several way from below ref:
Attribute property binding for background-image url in Angular 2
How to add background-image using ngStyle (angular2)?
Tried so far:
<li *ngFor="let article of arr;let i=index;">
<div *ngIf="i == 0" class="w3l_banner_nav_right_banner" [ngStyle]="{ 'background-url': 'url('+article.uri+')'} no-repeat 0px 0px;">
<h3>Make your <span>food</span> with Spicy.</h3>
<div class="more">
Shop now1
</div>
</div>
</li>
I am using Angular 4.1.3.
background-url is incorrect CSS, use background or background-image instead.
Here is an example of correct syntax:
<div [ngStyle]="{'background': '#fff url(' + article.uri + ') no-repeat 0 0'}"></div>
Your full example would look like this:
<li *ngFor="let article of arr; let i=index;" >
<div *ngIf="i == 0"
class="w3l_banner_nav_right_banner"
[ngStyle]="{'background': '#fff url(' + article.uri + ') no-repeat 0 0'}" >
<h3> Make your <span>food</span> with Spicy. </h3>
<div class="more">
Shop now1
</div>
</div>
</li>
If you're getting your background image from a remote source or a user input you will need to have angular sanitize the url. In your component you will want to add the following bits of code...
import { DomSanitizer } from '#angular/platform-browser';
export class YourComponent {
constructor(private _sanitizer: DomSanitizer) { }
public sanitizeImage(image: string) {
return this._sanitizer.bypassSecurityTrustStyle(`url(${image})`);
}
}
Try setting your HTML to this...
<li *ngFor="let article of arr;let i=index;">
<div *ngIf="i == 0" class="w3l_banner_nav_right_banner" [style.background-image]="sanitizeImage(article.uri)">
<h3>Make your <span>food</span> with Spicy.</h3>
<div class="more">
Shop now1
</div>
</div>
</li>
And apply the no-repeat 0px 0px; in some class you attach to the div.
The correct answer is [style.background-image]="'url(' + article.uri + ')'"
but if you are using ngFor for carousel, make sure you have added class 'active' properly.
This code will NOT working:
<div class="carousel-item active"
*ngFor="let article of arr;"
[style.background-image]="'url(' + article.uri + ')'"></div>
You should use 'active' class for first item only!
<div class="carousel-item"
*ngFor="let article of arr; let i = index;"
[ngClass]="{'active': i === 0}"
[style.background-image]="'url(' + article.uri + ')'"></div>
you can use it by adding url path in a single variable.
for example
bgImageVariable="www.domain.com/path/img.jpg";
[ngStyle]="{'background-image': 'url(' + bgImageVariable + ')'}"
Working for Angular 8+ (Power of template literals):
In component, define ngStyle object var (here called as styles, initialised in constructor):
const bgImageUrl = 'assets/images/dot-grid.png'
const styles = {
backgroundImage: `url(${bgImageUrl})`
};
In template, assign this as ngStyle
<div [ngStyle]="styles"><!-- your content --></div>
In my case the following syntax worked:
<ion-slide *ngFor="let page of pages">
<div class="cardImage" style.background-image="url('{{ page.imageUrl }}')"></div>
</ion-slide>
Ionic CLI : 6.16.3
This works fine for me:
js file:
path = 'url(../assets/about.png)';
array:
string[] = [this.path];
and HTML file:
<div *ngFor="let item of array" [ngStyle]="{'background-image': item}">
To solve this, the correct syntax is
<div class="modalContainer"
ng-style="{'background-image': 'url(' + selectedMeal.url + ')'}">

I am trying to perform concatenation in img tag and here below is what i am trying to do:
<div class="vx-row">
<div v-for="item in items" class="vx-col" v-bind:key="item.id">
<div class="w-full mb-base">
<vx-card>
...
<img :src="require('./img/stars_' + item.id + '_logo.png')" alt=""/>
...
</vx-card>
</div>
</div>
</div>
I am trying to concatenate the item.id to the image path as i am making my code dynamic such that when the cards are displayed then the respective image is displayed.
Please let me know how it can be done, initially i could see images in respective cards but then i tried using
<img :src="require(`./img/stars_${this.$route.params.item_id}_logo.png`)">
in other components then i get error every where.
Here is the error that i get everywhere:
Here you can try a shorthand that webpack will use.
HTML:
<img :src="getByPath(item.id)" v-bind:alt="item.id">
Method:
getByPath(id) {
return require('./img/stars_' + id + '_logo.png')
}
you can do with method like below code
try this:
<div class="vx-row">
<div v-for="item in items" class="vx-col" v-bind:key="item.id">
<div class="w-full mb-base">
<vx-card>
...
<img :src="getImgUrl(item.id)" alt=""/>
...
</vx-card>
</div>
</div>
</div>
and create method:
getImgUrl(value) {
return `./img/stars_${value}_logo.png`
},
I just wanted to fix the display of errors in the view page. It is being displayed as JSON format. How do I fix this?
Vue.component
<template>
<v-alert
dense
outlined
type="error"
>
{{ allerror }}
</v-alert>
...
...
</template>
<script>
data: () => ({
allerror: ''
}),
axios
.post('/api/section', { name, department_id })
.then(response => {
this.getSections()
this.snackbar.appear = true
this.snackbar.alert = response.data.alert
this.snackbar.icon = response.data.icon
this.$refs.form.reset()
})
.catch(error => this.allerror = error.response.data.errors)
</script>
there are 2 ways to go:
1 - Show specific errors on specific field by:
<v-text-field
label="Name"
v-model="name"
:error-messages="allerror.name"
></v-text-field>
2 - Show all error:
<v-alert
dense
outlined
type="error"
>
<ul>
<li v-for="(errors, field) in allerror">
{{ field }} //name of the field
//run second loop to display all errors for this field
<ul>
<li v-for="error in errors">
{{ error }}
</li>
</ul>
</li>
</ul>
</v-alert>
Add custom css class
.invalid-feedback {
width: 100%;
margin-top: 0.25rem;
font-size: 80%;
color: #e3342f;
}
Then bind invalid-feedback in the text field, if you are using laravel you can find invalid-feedback in app.css file
<v-text-field
v-model="form.email"
:rules="[rules.required, rules.emailRules]"
:class="{ 'is-invalid':
form.errors.has('email') }"
label="E-mail"
required
></v-text-field>
I am generating a report using dompdf. And tried repeating an element in a page where it could take up to 4 pages depending on the data. But it only created on the first page
Currently i have this html markup.
<html>
<head>
<style>
#page {
margin: .5in;
}
.footer{
position:fixed;
width:100%;
bottom:60px;
}
.page-3{
position:relative;
}
.repeat{
position:fixed;
width:100%;
top:10px;
}
</style>
</head>
<body>
<div class="page page-1">
<div class="content">
<div class="content-header">...</div>
<div class="content-text">...</div>
</div>
</div>
<div class="page page-2">
<div class="content">
<div class="content-header">...</div>
<div class="content-text">...</div>
</div>
</div>
<div class="page page-3">
<div class="content">
<div class="content-header repeat">
This must repeat in all pages generated
</div>
<div class="content-text">
atleast 2~4 pages
</div>
</div>
</div>
<div class="page page-4">
<div class="content">
<div class="content-header">...</div>
<div class="content-text">...</div>
</div>
</div>
<div class="footer">
footer
</div>
</body>
</html>
Let's say .page-3 generated 3 pages. But the .repeat is only seen on the first page inside .page-3
I tried using a background image for .page-3 but it still the same and is shown only on the first generated page.
I using the 0.8.2 version of dompdf.
If anyone is having a same problem as i have. I end up using a page_script.
Since i know the first 2 pages are static and the last page is static, I accessed the $PAGE_NUM and place a condition like this
`
$pdf->page_script('
if( $PAGE_NUM != 1 ){ // 1st page has no header
$text = "";
if( $PAGE_NUM == 2 ){
$text = "This is 2nd page";
}else if( $PAGE_NUM > 2 && $PAGE_NUM < $PAGE_COUNT ){
$text = "This is the page 3 until before the last page";
}else if( $PAGE_NUM == $PAGE_COUNT ){
$text = "This is last page";
}
// setup postioning, color, size etc for design
// use $text as header text
$pdf->text( $posX, $posY, $text, $font, $size, $color);
}
');
`
And removed all <div class="content-header">...</div> in the HTML markup
Is there a way to set the panel bar to a specific height (ie. 300px), and make that specific section scrollable if it's too long?
Assuming that you have your panelbar defined as a ul, something like:
<ul id="panelbar">
<li class="k-state-active">
<span class="k-link k-state-selected">My Teammates</span>
<div style="padding: 10px;">
<div class="teamMate">
<img src="../../content/web/panelbar/andrew.jpg" alt="Andrew Fuller">
<h2>Andrew Fuller</h2>
<p>Team Lead</p>
</div>
<div class="teamMate">
<img src="../../content/web/panelbar/nancy.jpg" alt="Nancy Leverling">
<h2>Nancy Leverling</h2>
<p>Sales Associate</p>
</div>
<div class="teamMate">
<img src="../../content/web/panelbar/robert.jpg" alt="Robert King">
<h2>Robert King</h2>
<p>Business System Analyst</p>
</div>
</div>
</li>
<li>
Projects
...
</li>
</ul>
You should define a CSS style as:
#panelbar {
height: 300px;
overflow-y: scroll;
}
See an example here: http://trykendoui.telerik.com/#OnaBai/ifus
The solution above scrolls the entire control. Here's how to scroll the panel's items.

I need some help about creating more HoverCards with this plugin (download). I just created a code demo on JSFiddle. Do you have any recommendations about this?
JavaScript:
$('.babe-hover').hovercard({
detailsHTML: $(this).attr('data-control').html(),
width:278
});
HTML:
<ul class="demo">
<li>
<span class="babe-hover" data-control="control-01">William Johnson</span>
<div id="control-01" style="display: none;">
<p class="s-desc">Address: 64 Newman Street.</p>
<ul class="s-stats">
<li>Tweets<br><span class="s-count">1337</span></li>
</ul>
</div>
</li>
<li>
<span class="babe-hover" data-control="control-02">Hanson Thomas</span>
<div id="control-02" style="display: none;">
<p class="s-desc">Address: 64 Newman Street.</p>
<ul class="s-stats">
<li>Tweets<br><span class="s-count">1337</span></li>
</ul>
</div>
</li>
Now it working with some help from the author
$('.babe-hover').each(function(){
var $this = $(this),
myControlId = $this.attr('data-control'),
htmlForHovercard = $('#'+ myControlId).html();
$this.hovercard({
detailsHTML: htmlForHovercard,
width:278
});
});
anyway thank #egasimus for ur suggest :)
I suppose you're asking: why doesn't this work?
You're trying to call the .html() method on what $(this).attr('data-control') returns. $(this).attr('data-control'), however, only returns a string, and you need to obtain the corresponding element in order to use .html(). The following code works for me:
$("#" + $(this).attr('data-control')).html()
I.e., "select the element whose id equals this element's data-control attribute, and call .html() on it."
