How can I make the <vue-autosuggest> input look like the input from BootstrapVue (<b-input>)?
To apply the form-control class to vue-autosuggest's inner <input>, as required for the Bootstrap <input> styles, you could use the inputProps prop (automatically applied to the <input>):
<template>
<vue-autosuggest :input-props="inputProps">
...
</vue-autosuggest>
</template>
<script>
export default {
data() {
return {
inputProps: {
class: 'form-control',
}
}
}
}
</script>
Interestingly, that class used to be added by default in vue-autosuggest 1.x, but was removed in 2.x.

You need to modify the the <input> tag of the vue-autosuggest component to include the class form-control from Vue-Bootstrap.
You will not be able to add this class directly to the component as the component wraps the input within a div block. Bootstrap CSS requires the the element to be of type input to properly match the CSS selectors.
If we look here https://github.com/darrenjennings/vue-autosuggest/blob/master/src/Autosuggest.vue at the component itself we see
<input
:type="internal_inputProps.type"
:value="internalValue"
:autocomplete="internal_inputProps.autocomplete"
:class="[isOpen ? `${componentAttrPrefix}__input--open` : '', internal_inputProps['class']]"
v-bind="internal_inputProps"
aria-autocomplete="list"
:aria-activedescendant="isOpen && currentIndex !== null ? `${componentAttrPrefix}__results-item--${currentIndex}` : ''"
:aria-controls="`${componentAttrIdAutosuggest}-${componentAttrPrefix}__results`"
#input="inputHandler"
#keydown="handleKeyStroke"
v-on="listeners"

This must be modified in your local version to include the bootstrap class.
I am trying to get the user input from my <paper-input-container> using this code:
<paper-input-container id="nameInput">
<label slot="label">Your name</label>
<iron-input slot="input">
<input on-keydown="keypressed" value="{{first}}" id="nameBox">
</iron-input>
</paper-input-container>
In my properties, I have:
static get properties() {
return {
first:{
type:String,
value:''
}
}
}
and my keypressed function is:
keypressed(e) {
console.log(this.first);
}
I've been able to get it to work with the <paper-input> element, but I wasn't able to style it the way I wanted to. If you know how to increase the user input text size on paper-input in Polymer 2.0, that would also help.
Polymer's change notification requires an event naming convention that the native <input> does not follow, so the two-way data binding you seek requires special syntax, as shown here:
target-prop="{{hostProp::target-change-event}}"
In your case, that would be:
<input value="{{first::input}}>
This tells Polymer to set first equal to value when the input event occurs from the <input>. This is equivalent to:
const inputEl = this.shadowRoot.querySelector('input');
inputEl.addEventListener('input', () => this.first = value);
demo
Alternatively, you could bind first to <iron-input>.bindValue, which reflects the value of <input>:
<iron-input bind-value="{{first}}">
<input>
</iron-input>

if you know how to increase the user input text size on paper-input in polymer 2.0, that would also help
The font-size of the <paper-input>'s inner <input> can be styled with the --paper-input-container-input CSS property of <paper-input-container>:
<dom-module id="x-foo">
<template>
<style>
paper-input {
--paper-input-container-input: {
font-size: 40px;
};
}
</style>
<paper-input label="My label" value="My value"></paper-input>
</template>
</dom-module>

I am using the react-select component on my app. I am also only styling my app with JSS. My issue is that since react-select is an npm package, I don't have the capability to modify class names in the component. So there is an input in there that I need to target with my styles.
<div class="Select-input"><input type="text" name="style-me" /></div>
And my JSS is a little something like this:
jss.setup(preset());
const stylus = {
'Select-input': {
background: 'red'
}
}
const { classes } = jss.createStyleSheet(stylus).attach();
What do I need to do in JSS to style that child input tag?
According to this answer, you can pass in a class name for react-select. The rest of my answer shows how to target child elements.
I checked the github page for JSS here:
https://github.com/cssinjs/jss
They have a live example for nested CSS rules here:
https://github.com/cssinjs/examples/blob/gh-pages/plugins/jss-nested/simple/app.js
In the code to target a nested <button> element, it uses a property named & button. Notice the space between the ampersand and button. So for your specific code, you can target the <input> like this:
jss.setup(preset());
const stylus = {
'Select-input': {
background: 'red',
'& input': {
/* your input styles here */
}
}
}
const { classes } = jss.createStyleSheet(stylus).attach();
Assuming you're referring to this package:
https://github.com/JedWatson/react-select
You can in fact pass in className as a prop
You have always at least 2 ways:
Pass the generated class name
Use JSS as you should by default, avoid unscoped class names. Use generated class name and pass it to the component you want to use
const {classes} = jss.createStyleSheet({
input: {background: 'red'}
}).attach()
<Input className={classes.input} />
Use scoped global selector
If its impossible to pass a class name, you can still have a locally scoped global selector
const {classes} = jss.createStyleSheet({
container: {
'#global': {
input: {background: 'red'}
}
}
}).attach()
<div className={classes.container}>
<Input />
</div>
I have a directive that I am currently making that is an input field of type text. Now I would like this field's width to grow dynamically if the text gets too big for the input field. Below is my directive:
.directive('dynamicInput', function () {
return {
restrict: 'E',
template: '<input type="text" style="display: inherit;" class="form-control" required />',
require: 'ngModel',
link: function (scope, element, attrs, ngModel) {
console.log('ATTRS: ', attrs);
console.log('ELEMENT: ', element);
if(attrs.width){
console.log('WiDTH: ', attrs);
}
}
}
});
Here is the plunker:
Change Width Dynamically.
I know you can change the CSS class youre using on your element object, however, I dont just want to change the class I want to basically dynamically change the width as the text increases inside the box. So the question is: How can I change the CSS on every fire of the 'onchange' event to the length of the text being entered? Also, I would like to keep this contained within a directive, so that I am not relying on anything within the parent scope in which its declared in.
You can get your input element, and then do whatever you want with it using vanilla javascript or angular object element.
Like this (link function):
var inputEl = angular.element(element.children()[0]);
inputEl.on('keydown', function() {
inputEl.attr('size', inputEl.val().length);
});
This does not do exactly what you want I think, but you get the idea.
You have access to the element inside the directive, so this kind of logic is very easy to implement without depending on anything else but itself.
Modified plunker.
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:
