I have a <v-text-field> which collects user e-mail address and I need to add ym-record-keys CSS class to <input> element according to Yandex Metrica guideline. So I tried to add it like this but it adds class to the parent div. How can I add ym-record-keys class to HTML input element?
<v-text-field
v-model="item.customer.mail"
type="email"
:rules="emailRules"
hide-details="auto"
class="ym-record-keys"
solo
>
</v-text-field>
I need to achieve this output:
<input id="input-1055" type="email" class="ym-record-keys">
I needed this ability as well because another plugin I was using expects a certain class to exist on my input elements.
In order to achieve this I created a simple wrapper around Vuetify's v-text-field that adds the ability to pass in a class to the input element:
Create a TextInput.vue component:
<script>
import { VTextField } from 'vuetify/lib';
export default {
name: 'text-input',
extends: VTextField,
props: {
inputClass: {
note: 'A class that gets applied to the input',
},
},
mounted() {
// Applying the `class` to the input
// element below if it has values
const inputEl = this.$el.querySelector('input');
if (this.inputClass) {
inputEl.classList.add(this.inputClass);
}
},
};
</script>
Then used like this:
<text-input v-model="myModel" input-class="my-css-class" />
Which results in your input looking like this:
<input id="idGeneratedFromVuetify" type="text" class="my-css-class">
You can modify this to fit any other attributes you may want, or you could make it more dynamic if your use case needs that by using the spread operator with props.
You can try the following to bind the class
:class=["ym-record-keys"]
or
:class="'ym-record-keys'"
When Gutenberg creates a class, it seems to be of the format
div.wp-block
div.editor-block-list__insertion-point
div.editor-block-list__block-edit
div.editor-block-contextual-toolbar
div
<your actual block html goes here>
I'd like to be able to add a class to that top div.wp-block element so I can properly style my block in the editor. The class is dynamically generated based on an attribute so I can't just use the block name class. Is there a clean way of doing this? I can hack it using javascript DOM, but it gets overwritten quickly enough.
https://wordpress.org/gutenberg/handbook/designers-developers/developers/filters/block-filters/#editor-blocklistblock
const { createHigherOrderComponent } = wp.compose
const withCustomClassName = createHigherOrderComponent((BlockListBlock) => {
return props => {
return <BlockListBlock { ...props } className={ 'my-custom-class' } />
}
}, 'withCustomClassName')
wp.hooks.addFilter('editor.BlockListBlock', 'my-plugin/with-custom-class-name', withCustomClassName)
You can add class in your block edit view by using className that is present in this.props, className will print class in following format wp-blocks-[block_name]
edit( { className } ) { // using destructing from JavaScript ES-6
return <div className={ className }></div>
}
Suggestion
Always try to look for manipulating DOM via React instead of manipulating DOM directly because React manages it's own state and issues can occur by manipulating DOM directly.
I have input element as shown :
<input type="text" class="bg-white" id="couponCode" value="">
How can i set/fill its value using casperJs
Using casper.sendKeys('selector', value);
http://casperjs.readthedocs.org/en/latest/modules/casper.html#sendkeys
There are a few different methods available for accomplishing this task.
You should use casper.sendKeys() unless you need to perform a more complex operation.
casper.sendKeys():
If you would like to set the value from the CasperJS environment, and the input element is optionally inside a form element, then you can use casper.sendKeys():
casper.sendKeys('#couponCode', 'Hello, world!');
casper.fill():
If you would like to set the value from the CasperJS environment, and the input element is inside a form element, and includes a name attribute, then you can use casper.fill():
casper.fill('#form', {
couponCode: 'Hello, world!', // #form [name="couponCode"]
});
casper.fillSelectors():
If you would like to set the value from the CasperJS environment, and the input element is inside a form element, and you would like to reference the input element using a CSS3 selector, then you can use casper.fillSelectors():
casper.fillSelectors('#form', {
'#couponCode': 'Hello, world!', // #form #couponCode
});
casper.fillLabels():
If you would like to set the value from the CasperJS environment, and the input element is inside a form element, and includes an associated label element with text, then you can use casper.fillLabels():
casper.fillLabels('#form', {
couponCode: 'Hello, world!', // #form label[text()="couponCode"] input
});
casper.fillXPath():
If you would like to set the value from the CasperJS environment, and the input element is inside a form element, and you would like to reference the input element using an XPath selector, then you can use casper.fillXPath():
casper.fillXPath('#form', {
'//*[#id="couponCode"]': 'Hello, world!', // #form #couponCode
});
casper.evaluate():
If you would like to set the value from the Page DOM environment, and the input element is optionally inside a form element, then you can use casper.evaluate():
casper.evaluate(function () {
document.getElementById('couponCode').value = 'Hello, world!';
});
Note: Similarly to evaluate(), you can also use: evaluateOrDie(), thenEvaluate(), or thenOpenAndEvaluate() (if you would like to accomplish two or more operations at once in relation to the steps being executed).
Q1. Suppose I want to alter the look of each "item" that a user marks for deletion before the main "delete" button is pressed. (This immediate visual feedback should eliminate the need for the proverbial "are you sure?" dialog box.) The user will check checkboxes to indicate which items should be deleted. If a checkbox is unchecked, that item should revert back to its normal look.
What's the best way to apply or remove the CSS styling?
Q2. Suppose I want to allow each user to personalize how my site is presented. E.g., select from a fixed set of font sizes, allow user-definable foreground and background colors, etc.
What's the best way to apply the CSS styling the user selects/inputs?
Angular provides a number of built-in directives for manipulating CSS styling conditionally/dynamically:
ng-class - use when the set of CSS styles is static/known ahead of time
ng-style - use when you can't define a CSS class because the style values may change dynamically. Think programmable control of the style values.
ng-show and ng-hide - use if you only need to show or hide something (modifies CSS)
ng-if - new in version 1.1.5, use instead of the more verbose ng-switch if you only need to check for a single condition (modifies DOM)
ng-switch - use instead of using several mutually exclusive ng-shows (modifies DOM)
ng-disabled and ng-readonly - use to restrict form element behavior
ng-animate - new in version 1.1.4, use to add CSS3 transitions/animations
The normal "Angular way" involves tying a model/scope property to a UI element that will accept user input/manipulation (i.e., use ng-model), and then associating that model property to one of the built-in directives mentioned above.
When the user changes the UI, Angular will automatically update the associated elements on the page.
Q1 sounds like a good case for ng-class -- the CSS styling can be captured in a class.
ng-class accepts an "expression" that must evaluate to one of the following:
a string of space-delimited class names
an array of class names
a map/object of class names to boolean values
Assuming your items are displayed using ng-repeat over some array model, and that when the checkbox for an item is checked you want to apply the pending-delete class:
<div ng-repeat="item in items" ng-class="{'pending-delete': item.checked}">
... HTML to display the item ...
<input type="checkbox" ng-model="item.checked">
</div>
Above, we used ng-class expression type #3 - a map/object of class names to boolean values.
Q2 sounds like a good case for ng-style -- the CSS styling is dynamic, so we can't define a class for this.
ng-style accepts an "expression" that must evaluate to:
an map/object of CSS style names to CSS values
For a contrived example, suppose the user can type in a color name into a texbox for the background color (a jQuery color picker would be much nicer):
<div class="main-body" ng-style="{color: myColor}">
...
<input type="text" ng-model="myColor" placeholder="enter a color name">
Fiddle for both of the above.
The fiddle also contains an example of ng-show and ng-hide. If a checkbox is checked, in addition to the background-color turning pink, some text is shown. If 'red' is entered in the textbox, a div becomes hidden.
I have found problems when applying classes inside table elements when I had one class already applied to the whole table (for example, a color applied to the odd rows <myClass tbody tr:nth-child(even) td>). It seems that when you inspect the element with Developer Tools, the element.style has no style assigned. So instead of using ng-class, I have tried using ng-style, and in this case, the new CSS attribute does appear inside element.style. This code works great for me:
<tr ng-repeat="element in collection">
[...amazing code...]
<td ng-style="myvar === 0 && {'background-color': 'red'} ||
myvar === 1 && {'background-color': 'green'} ||
myvar === 2 && {'background-color': 'yellow'}">{{ myvar }}</td>
[...more amazing code...]
</tr>
Myvar is what I am evaluating, and in each case I apply a style to each <td> depending on myvar value, that overwrites the current style applied by the CSS class for the whole table.
UPDATE
If you want to apply a class to the table for example, when visiting a page or in other cases, you can use this structure:
<li ng-class="{ active: isActive('/route_a') || isActive('/route_b')}">
Basically, what we need to activate a ng-class is the class to apply and a true or false statement. True applies the class and false doesn't. So here we have two checks of the route of the page and an OR between them, so if we are in /route_a OR we are in route_b, the active class will be applied.
This works just having a logic function on the right that returns true or false.
So in the first example, ng-style is conditioned by three statements. If all of them are false, no style is applied, but following our logic, at least one is going to be applied, so, the logic expression will check which variable comparison is true and because a non empty array is always true, that will left an array as return and with only one true, considering we are using OR for the whole response, the style remaining will be applied.
By the way, I forgot to give you the function isActive():
$rootScope.isActive = function(viewLocation) {
return viewLocation === $location.path();
};
NEW UPDATE
Here you have something I find really useful. When you need to apply a class depending on the value of a variable, for example, an icon depending on the contents of the div, you can use the following code (very useful in ng-repeat):
<i class="fa" ng-class="{ 'fa-github' : type === 0,
'fa-linkedin' : type === 1,
'fa-skype' : type === 2,
'fa-google' : type === 3 }"></i>
Icons from Font Awesome
This works well when ng-class can't be used (for example when styling SVG):
ng-attr-class="{{someBoolean && 'class-when-true' || 'class-when-false' }}"
(I think you need to be on latest unstable Angular to use ng-attr-, I'm currently on 1.1.4)
I have published an article on working with AngularJS+SVG. It talks about this issue and numerous others. http://www.codeproject.com/Articles/709340/Implementing-a-Flowchart-with-SVG-and-AngularJS
span class="circle circle-{{selectcss(document.Extension)}}">
and code
$scope.selectcss = function (data) {
if (data == '.pdf')
return 'circle circle-pdf';
else
return 'circle circle-small';
};
css
.circle-pdf {
width: 24px;
height: 24px;
font-size: 16px;
font-weight: 700;
padding-top: 3px;
-webkit-border-radius: 12px;
-moz-border-radius: 12px;
border-radius: 12px;
background-image: url(images/pdf_icon32.png);
}
This solution did the trick for me
<a ng-style="{true: {paddingLeft: '25px'}, false: {}}[deleteTriggered]">...</a>
You can use ternary expression. There are two ways to do this:
<div ng-style="myVariable > 100 ? {'color': 'red'} : {'color': 'blue'}"></div>
or...
<div ng-style="{'color': (myVariable > 100) ? 'red' : 'blue' }"></div>
Another option when you need a simple css style of one or two properties:
View:
<tr ng-repeat="element in collection">
[...amazing code...]
<td ng-style="{'background-color': getTrColor(element.myvar)}">
{{ element.myvar }}
</td>
[...more amazing code...]
</tr>
Controller:
$scope.getTrColor = function (colorIndex) {
switch(colorIndex){
case 0: return 'red';
case 1: return 'green';
default: return 'yellow';
}
};

As of AngularJS v1.2.0rc, ng-class and even ng-attr-class fail with SVG elements (They did work earlier, even with normal binding inside the class attribute)
Specifically, none of these work now:
ng-class="current==this_element?'active':' ' "
ng-attr-class="{{current==this_element?'active':' '}}"
class="class1 class2 .... {{current==this_element?'active':''}}"
As a workaround, I've to use
ng-attr-otherAttr="{{current==this_element?'active':''}}"
and then style using
[otherAttr='active'] {
... styles ...
}
One more (in the future) way to conditionally apply style is by conditionally creating scoped style
<style scoped type="text/css" ng-if="...">
</style>
But nowadays only FireFox supports scoped styles.
There is one more option that I recently discovered that some people may find useful because it allows you to change a CSS rule within a style element - thus avoiding the need for repeated use of an angular directive such as ng-style, ng-class, ng-show, ng-hide, ng-animate, and others.
This option makes use of a service with service variables which are set by a controller and watched by an attribute-directive I call "custom-style". This strategy could be used in many different ways, and I attempted to provide some general guidance with this fiddle.
var app = angular.module('myApp', ['ui.bootstrap']);
app.service('MainService', function(){
var vm = this;
});
app.controller('MainCtrl', function(MainService){
var vm = this;
vm.ms = MainService;
});
app.directive('customStyle', function(MainService){
return {
restrict : 'A',
link : function(scope, element, attr){
var style = angular.element('<style></style>');
element.append(style);
scope.$watch(function(){ return MainService.theme; },
function(){
var css = '';
angular.forEach(MainService.theme, function(selector, key){
angular.forEach(MainService.theme[key], function(val, k){
css += key + ' { '+k+' : '+val+'} ';
});
});
style.html(css);
}, true);
}
};
});
well i would suggest you to check condition in your controller with a function returning true or false .
<div class="week-wrap" ng-class="{today: getTodayForHighLight(todayDate, day.date)}">{{day.date}}</div>
and in your controller check the condition
$scope.getTodayForHighLight = function(today, date){
return (today == date);
}
One thing to watch is - if the CSS style has dashes - you must remove them. So if you want to set background-color, the correct way is:
ng-style="{backgroundColor:myColor}"
Here's how i conditionally applied gray text style on a disabled button
import { Component } from '#angular/core';
#Component({
selector: 'my-app',
styleUrls: [ './app.component.css' ],
template: `
<button
(click)='buttonClick1()'
[disabled] = "btnDisabled"
[ngStyle]="{'color': (btnDisabled)? 'gray': 'black'}">
{{btnText}}
</button>`
})
export class AppComponent {
name = 'Angular';
btnText = 'Click me';
btnDisabled = false;
buttonClick1() {
this.btnDisabled = true;
this.btnText = 'you clicked me';
setTimeout(() => {
this.btnText = 'click me again';
this.btnDisabled = false
}, 5000);
}
}
Here's a working example:

How to add, remove and change css classes for an ember element based on the value from the contentBinding while doing ember each?
Doing something like below in didInsertElement, but by the time have added the css classes, based on content value from controller, view element is attached to the view and hence css doesn't get applied.
Is there any other way that we could perform this while view element is getting rendered?
didInsertElement: function() {
this._super();
var personStr= this.get("content").person;
if(personStr==1){
this.$("img").addClass("add-person");
this.$("img").removeClass("view-person");
this.$("img").removeClass("edit-person");
}
}
You could use a Ember.CollectionView and specify your classes which depend on the content in classNameBindings. See API documentation, section HTML class Attribute.
See an example here http://jsfiddle.net/pangratz666/b4xGP/:
Ember.CollectionView.create({
content: [{name: 'Brunö'}, {name: 'Alfred'}, {name: 'Hansi'}],
itemViewClass: Ember.View.extend({
templateName: 'item',
classNameBindings: 'beginsWithA'.w(),
beginsWithA: function() {
var name = this.getPath('content.name');
if (!Ember.empty(name)) {
return name.indexOf('A') === 0;
}
}.property('content.name')
})
}).append();
