angular 2 img width sets to 0 - image

So I am setting the image source and width dynamically in my template. The problem I see is that it sets the width to 0.
The template looks like:
<img src="{{item.msg}}" width="{{item.width}}" style="float:right" *ngIf="item.templateType == 'image'" />{{item.width}}
The value is passed as below from .ts
this.items.push(new ImageMessage('http://someimage.png', '100%'));
What I see is that it does not display the image but prints the value of item.width correctly. Looking into inspector it shows the width is set to 0 which explains why image is not appearing.
However, I am failing to understand why the width is getting set to 0 in img tag.
Please help.
Thanks.

You can set the width as a percentage using one-way binding syntax [style.width.%] targeting the style attribute binding of an element like <img /> in your example. HTML5 does require that the width property is in pixels, so using the [style.width.%] attribute binding would allow you to set the width as a percentage.
You're ImageMssage object would need to have the percentage '%' character removed from the width value of the ImageMessage object to make this work. With this syntax, it's flexible to work with either strings or numbers. Either '100' or 100 would work.

template: `
<div>

this.items = [

{ msg: 'http://placehold.it/800', width: '75' },
{ msg: 'http://placehold.it/800', width: 50 },

];
}
}
#NgModule({
imports: [ BrowserModule, CommonModule ],
declarations: [ App ],
bootstrap: [ App ]
})
export class AppModule {}
If you want to set the pixels, you can use the following:
<img [src]="item.msg" [style.width.px]="item.width" ... />{{item.width}}px
Here is a plunker demonstrating the functionality.
Hopefully this helps!

I think it may set the width to 0 because you have have 100% in single quotation marks. As in { width: '100%' } try removing the quotation marks to produce { width: 100% }. This may also explain why it prints the value of item.width.

Vuetify breadcrumbs text color

I'm trying to have different text colors for my breadcrumbs based on a property but I can't figure out how to apply those colors anywhere. Can't add a color or class in the items either.
breadcrumbItems() {
return [
{
text: this.$t("receiving.breadcrumbs.step1"),
disabled: this.item.Status !== "STEP1"
},
{
text: this.$t("receiving.breadcrumbs.step2"),
disabled: this.item.Status !== "STEP2"
},
{
text: this.$t("receiving.breadcrumbs.step3"),
disabled: this.item.Status !== "STEP3"
}
];
}
<v-breadcrumbs :items="breadcrumbItems" class="breadStyle">
<template v-slot:divider>
<v-icon size="25">mdi-forward</v-icon>
</template>
</v-breadcrumbs>
Looking at the API for v-breadcrumbs: https://vuetifyjs.com/en/api/v-breadcrumbs-item/ it doesn't provide a property "color" or something similar, but there is a slot, so you can pass any kind of components in it.
You can create a <span> and customize its color and its style depending on the items:
<template>
<v-breadcrumbs :items="items">
<template v-slot:divider>
<v-icon size="25">mdi-forward</v-icon>
</template>
<template v-slot:item="{ item }">
<v-breadcrumbs-item :disabled="item.disabled">
<span :style="`color: ${item.color}`">
{{ item.text.toUpperCase() }}
</span>
</v-breadcrumbs-item>
</template>
</v-breadcrumbs>
</template>
<script>
export default {
data: () => ({
items: [
{
text: "Dashboard",
disabled: false,
color: "green",
},
{
text: "Link 1",
disabled: false,
color: "blue",
},
{
text: "Link 2",
disabled: true,
color: "red",
},
],
}),
};
</script>
I've found that the deep selector (https://vue-loader.vuejs.org/guide/scoped-css.html#deep-selectors) often helps with styling Vuetify components. I added this to my components scoped CSS and the colours work just fine for links:
.v-breadcrumbs >>> a {
color: purple;
}
I found the relevant tag by looking through the Elements-tab under Inspect (in Chrome).
I don't know if this is the best solution for your specific situation, but figured I'd add this for anyone with a simpler use case.

Changing background color of selected item in kendo ui mutiselect angular

I am trying to execute kendo ui multiselect some what like code below.But i need to change the background color of selected item from red color to some other color.I tried giving custom css in popupsettings but still it is not working.
Most googled answers are in jquery but i need it in angular 4.Could you please help me out
import { Component } from '#angular/core';
#Component({
selector: 'my-app',
template: `
<p>Custom values are <strong>enabled</strong>. Type a custom value.</p>
<p>primitive data</p>
<div class="example-wrapper">
<kendo-multiselect
[data]="sizes"
[value]="selectedSizes"
[allowCustom]="true"
(valueChange)="onSizeChange($event)"
>
<ng-template kendoMultiSelectCustomItemTemplate let-customText>
<strong>{{ customText }}</strong>
</ng-template>
</kendo-multiselect>
</div>
`
})
export class AppComponent {
public sizes: Array<string> = [ "Small", "Medium", "Large" ];
public selectedSizes: Array<string> = [];
public onSizeChange(value) {
this.selectedSizes = value;
}
}
Add the following CSS to your component:
::ng-deep .k-item.k-state-selected {
background-color: green !important;
}
This is kendo solution.
:host ::ng-deep .k-state-selected {
background-color: green !important;
}

How to set the height of CKEditor 5 (Classic Editor)

In CKEditor 4 to change the editor height there was a configuration option: config.height.
How do I change the height of CKEditor 5? (the Classic Editor)
Answering my own question as it might help others.
CKEditor 5 no longer comes with a configuration setting to change its height.
The height can be easily controlled with CSS.
There is one tricky thing though, if you use the Classic Editor:
<div id="editor1"></div>
ClassicEditor
.create( document.querySelector( '#editor1' ) )
.then( editor => {
// console.log( editor );
} )
.catch( error => {
console.error( error );
} );
Then the Classic Editor will hide the original element (with id editor1) and render next to it. That's why changing height of #editor1 via CSS will not work.
The simplified HTML structure, after CKEditor 5 (the Classic Editor) renders, looks as follows:
<!-- This one gets hidden -->
<div id="editor1" style="display:none"></div>
<div class="ck-reset ck-editor..." ...>
<div ...>
<!-- This is the editable element -->
<div class="ck-blurred ck-editor__editable ck-rounded-corners ck-editor__editable_inline" role="textbox" aria-label="Rich Text Editor, main" contenteditable="true">
...
</div>
</div>
</div>
In reality the HTML is much more complex, because the whole CKEditor UI is rendered. However the most important element is the "editing area" (or "editing box") marked with a ck-editor__editable_inline class:
<div class="... ck-editor__editable ck-editor__editable_inline ..."> ... </div>
The "editing area" is the white rectangle where one can enter the text. So to style / change the height of the editing area, it is enough to target the editable element with CSS:
<style>
.ck-editor__editable_inline {
min-height: 400px;
}
</style>
Setting the height via a global stylesheet.
Just add to your common .css file (like style.css):
.ck-editor__editable {
min-height: 500px;
}
In the case of ReactJS.
<CKEditor
editor={ClassicEditor}
data="<p>Hello from CKEditor 5!</p>"
onInit={(editor) => {
// You can store the "editor" and use when it is needed.
// console.log("Editor is ready to use!", editor);
editor.editing.view.change((writer) => {
writer.setStyle(
"height",
"200px",
editor.editing.view.document.getRoot()
);
});
}}
/>
editor.ui.view.editable.editableElement.style.height = '300px';
From CKEditor 5 version 22 the proposed programmatic solutions are not working. Here it is how I get the work done:
ClassicEditor.create( document.querySelector( '#editor' ) )
.then( editor => {
editor.ui.view.editable.element.style.height = '500px';
} )
.catch( error => {
console.error( error );
} );
.ck-editor__editable {min-height: 500px;}
<div>
<textarea id="editor">Hi world!</textarea>
</div>
<script src="https://cdn.ckeditor.com/ckeditor5/22.0.0/classic/ckeditor.js"></script>
Add this to your stylesheet:
.ck-editor__editable {
min-height: 200px !important;
}
If you wish to do this programatically, the best way to do it is to use a Plugin. You can easily do it as follows. The following works with CKEditor 5 version 12.x
function MinHeightPlugin(editor) {
this.editor = editor;
}
MinHeightPlugin.prototype.init = function() {
this.editor.ui.view.editable.extendTemplate({
attributes: {
style: {
minHeight: '300px'
}
}
});
};
ClassicEditor.builtinPlugins.push(MinHeightPlugin);
ClassicEditor
.create( document.querySelector( '#editor1' ) )
.then( editor => {
// console.log( editor );
})
.catch( error => {
console.error( error );
});
Or if you wish to add this to a custom build, you can use the following plugin.
class MinHeightPlugin extends Plugin {
init() {
const minHeight = this.editor.config.get('minHeight');
if (minHeight) {
this.editor.ui.view.editable.extendTemplate({
attributes: {
style: {
minHeight: minHeight
}
}
});
}
}
}
This adds a new configuration to the CKEditor called "minHeight" that will set the editor minimum height which can be used like this.
ClassicEditor
.create(document.querySelector( '#editor1' ), {
minHeight: '300px'
})
.then( editor => {
// console.log( editor );
} )
.catch( error => {
console.error( error );
} );
I tried to set the height and width on the config but it just didn't work on the classic Editor.
I was able to change the height of the editor programmatically on Vue by doing this.
mounted() {
const root = document.querySelector('#customer_notes');
ClassicEditor.create(root, config).then(editor=>{
// After mounting the application change the height
editor.editing.view.change(writer=>{
writer.setStyle('height', '400px', editor.editing.view.document.getRoot());
});
});
}
Use css:
.ck.ck-editor__main .ck-content {
height: 239px;
}
Add this to your global stylesheet, this will increase the size of the CKEditor :)
.ck-editor__editable_inline {
min-height: 500px;
}
Just add it to the style tag.
<style>
.ck-editor__editable
{
min-height: 150px !important;
max-height: 400px !important;
}
</style>
As for configuring the width of the CKEditor 5:
CKEditor 5 no longer comes with a configuration setting to change its width but its width can be easily controlled with CSS.
To set width of the editor (including toolbar and editing area) it is enough to set width of the main container of the editor (with .ck-editor class):
<style>
.ck.ck-editor {
max-width: 500px;
}
</style>
Simply you can add this to your CSS file
.ck-editor__editable {min-height: 150px;}
Put this CSS in your global CSS file and the magic will happen. CkEditor is full of unsolved mysteries.
.ck-editor__editable_inline {
min-height: 400px;
}
Use max-height and min-height both. Beacuse max-height give scroll bar option after reached maximum mention height. Where min-height give static height to <textarea>.
.ck-editor__editable {
max-height: 400px; min-height:400px;}
If its in latest version of Angular say 12 or 12+. We can add below style to your components style file.
:host ::ng-deep .ck-editor__editable_inline { min-height: 300px; }
If you use jQuery and the CKEditor 5 has to be applied to a textarea, there is a "quick and dirty" solution.
The condition:
<textarea name='my-area' id='my_textarea_id'>
If you use jQuery the Editor call could be:
var $ref=$('#my_textarea_id');
ClassicEditor
.create( $ref[0] ,{
// your options
} )
.then( editor => {
// Set custom height via jQuery by appending a scoped style
$('<style type="text/css" scoped>.ck-editor .ck-editor__editable_inline {min-height: 200px !important;}</style>').insertAfter($ref);
} )
.catch( error => {
console.error( error );
} );
In other words, after rendering, you can address the same element used to build the editor and append after a scoped style tag with containing the custom height.
$('<style type="text/css" scoped>.ck-editor .ck-editor__editable_inline {min-height: 200px !important;}</style>').insertAfter($ref);
If you like to use a function (or some class method) to do this, you need something like this:
var editorBuildTo = function(id,options){
var options=options || {};
//Height represents the full widget height including toolbar
var h = options.height || 250; //Default height if not set
var $ref = $('#'+id);
h=(h>40?h-40:h);//Fix the editor height if the toolbar is simple
ClassicEditor
.create( $ref[0] ,{
// your options
} )
.then( editor => {
// Set custom height via jQuery
$('<style type="text/css" scoped>.ck-editor .ck-editor__editable_inline {min-height: '+h+'px !important;}</style>').insertAfter($ref);
} )
.catch( error => {
console.error( error );
} );
}
editorBuildTo('my_textarea_id',{
height:175,
// other options as you need
});
This works well for me

Building on #Jaskaran Singh React solution. I also needed to ensure it was 100% height to it's parent. I achieved this by assigning a ref called "modalComponent" and further adding this code:
editor.editing.view.change(writer => {
let reactRefComponentHeight = this.modalComponent.current.offsetHeight
let editorToolbarHeight = editor.ui.view.toolbar.element.offsetHeight
let gapForgiveness = 5
let maximizingHeight = reactRefComponentHeight - editorToolbarHeight - gapForgiveness
writer.setStyle(
'height',
`${maximizingHeight}px`,
editor.editing.view.document.getRoot()
)
})
This CSS Method works for me:
.ck-editor__editable {
min-height: 400px;
}
I resolve this just adding in my layout page
<style>
.ck-content{
height: 250px;
}
</style>
Hope i help someone :D
For this particular version https://cdn.ckeditor.com/4.16.0/standard/ckeditor.js,
the below code block worked for me.
.cke_contents { height: 500px !important; }
I guess the difference is just the fact that is it in plural.
In my case it worked for me
Add a ck class and write style like below:
<style>
.ck {
height: 200px;
}
</style>
Using plugin here I came up with this
let rows: number;
export class MinHeightPlugin {
constructor(public editor) {
}
init = function () {
this.editor.ui.view.editable.extendTemplate({
attributes: {
style: {
minHeight: (rows * 40) + 'px',
}
}
});
};
}
export const MinHeightPluginFactory = (rowss: number): typeof MinHeightPlugin => {
rows = rowss;
return MinHeightPlugin;
};
and the usage(4 rows each rows is considered 40px height):
this.editor.builtinPlugins.push(MinHeightPluginFactory(4));
I couldn't manage to make rows variable local to MinHeightPlugin, does anyone know how to do it?
.ck-editor__editable_inline {
min-height: 400px;
}
This makes height change for every editor used across all components. So it doesn't work in my case.
In Case of react js
<CKEditor
toolbar = {
[
'heading',
'bold',
'Image'
]
}
editor={ClassicEditor}
data={this.state.description}//your state where you save data
config={{ placeholder: "Enter description.." }}
onChange={(event, editor) => {
const data = editor.getData();
this.setState({
description : data
})
}}
onReady={(editor)=>{
editor.editing.view.change((writer) => {
writer.setStyle(
//use max-height(for scroll) or min-height(static)
"min-height",
"180px",
editor.editing.view.document.getRoot()
);
});
}}
/>
In order to enable both rich text editor and source mode to have the same height, use the following CSS:
.ck-source-editing-area,
.ck-editor__editable {
min-height: 500px;
}
.ck-editor__main {
height: 500px;
min-height: 500px;
max-height: 500px;
overflow-y: scroll;
border: 1px solid #bbbbbb;
}
Just test it's work. Hoping help you
var editor_ = CKEDITOR.replace('content', {height: 250});

How do i use animation in Angular2 for Router Compoenents

I want to animate in and out my components when the active router link changes. How do I write the code the animation code so that when the router changes, a component fades out then another fades in?
The code that I've been trying is the following.
#Component({
selector: 'app-component',
templateUrl: './component.component.html',
animations: [trigger(
'openClose',
[
transition(":enter", [
style({ opacity: 0 }),
animate('2000ms', style({ opacity: 1 }))
]),
transition(":leave", [
animate('2000ms', style({ opacity: 0 }))
])
])]
})
But I think I got the concept wrong, as I'm trying to use that piece of code in at least 2 components but none of them is fading in or out.
Is this possible to do with this function or am i tackling the issue with a wrong manner?
Example with Angular 4
Here's how I implemented a fade in animation on my home component route
import { Component } from '#angular/core';
import { fadeInAnimation } from '../_animations/index';
#Component({
moduleId: module.id.toString(),
templateUrl: 'home.component.html',
animations: [fadeInAnimation],
host: { '[#fadeInAnimation]': '' }
})
export class HomeComponent {
}
This is the animation defined in a separate file
import { trigger, state, animate, transition, style } from '#angular/animations';
export const fadeInAnimation =
trigger('fadeInAnimation', [
// route 'enter' transition
transition(':enter', [
// styles at start of transition
style({ opacity: 0 }),
// animation and styles at end of transition
animate('.3s', style({ opacity: 1 }))
]),
]);
For other animations and a live demo you can check out this post
Your code seems correct to me, you just need to bind the animation to a component. There are two ways:
Add it to your template, for example to a div:
<div class="container" [#openClose]="'true'">
...
</div>
Or directly apply it to your host component (<app-component>):
#Component({
selector: 'app-component',
templateUrl: './component.component.html',
animations: [trigger(
'openClose',
[
transition(":enter", [
style({ opacity: 0 }),
animate('2000ms', style({ opacity: 1 }))
]),
transition(":leave", [
animate('2000ms', style({ opacity: 0 }))
])
])],
host: {
'[#openClose]': 'true',
'style': 'display: block;'
},
})
The animation works by component, so you need to declare the animation on both of them.
The leave animation may not be noticed on state change. The official documentation has an example on how to use animations in route components
Hope it helps!
