Angularjs/Bootstrap - how to create a stateless button - angularjs

Using Bootstrap and Angularjs I'd like to create a button that doesn't ever appear to be "active". I'd like the button to darken slightly when the mouse is over it, and I'd like it to darken further when it's clicked. When the mouse leaves the button, however, I'd like it to return to its original appearance.
Semantically, I'm using the button to "reset" part of my app. I want to execute some code when it's clicked. After it's been pressed, though, it doesn't make sense for the button to remain in a "depressed" state.
Here's a live example.
Any ideas?

Alternatively you could use the ng-mouseenter and ng-mosueleave directives.
For example:
<div ng-app="ButtonApp">
<div ng-controller="MainCtrl">
<button ng-class="buttonClass"
ng-mouseenter="onMouseEnter()"
ng-mouseleave="onMouseLeave()"> Click Me!
</div>
</div>
And in your controller:
var app = angular.module('ButtonApp',[]);
app.controller('MainCtrl', ['$scope',function($scope){
var defaultButtonClass = ['btn','btn-foxtrot'];
$scope.buttonClass = defaultButtonClass;
$scope.onMouseEnter = function(){
$scope.buttonClass = ['btn','btn-bravo'];
};
$scope.onMouseLeave = function() {
$scope.buttonClass = defaultButtonClass;
}
}]);
You can see my JSFiddle.
To generate the button colors you could use something like Beautiful Buttons for
Twitter Bootstrappers.

I'd give it another class, say btn-reset and add the following CSS.
// the order of these two is also important
.btn-reset:hover{
background-color: Dark !important;
}
.btn-reset:active{
background-color: Darkest !important;
}
// you need this to reset it after it's been clicked and released
.btn-reset:focus{
background-color: Normal !important;
}
It's working here http://plnkr.co/edit/QVChtJ8w70HXmyAaVY4A?p=preview
The issue is that the :focus pseudo class has a darker colour than the standard button so after it's been clicked it still has focus so still has the darker colour, if you want to stick with the standard colours you can just add a new selector for the :focus pseudo class.

AgGrid: How to blink cell in different color depending on change

I'm using ag-grid-react like this:
import { AgGridReact } from "ag-grid-react";
import "ag-grid-community/dist/styles/ag-grid.css";
import "ag-grid-community/dist/styles/ag-theme-balham.css";
and declares it like this in render(some details removed for clarity):
return <div className="MarketGrid ag-theme-balham" >
<AgGridReact domLayout='autoHeight'
enableCellChangeFlash={true}
rowSelection={'single'}
onSelectionChanged={this.onSelectionChanged.bind(this)}
onGridReady={this.onGridReady.bind(this)} />
</div>;
the "enableCellChangeFlash" property works fine, and I know how to change the color of it, but what if I want to change the color depending on whether the new value is higher or lower than the previous?
My update code looks somewhat like this:
let row = this.gridApi.getRowNode(this.props.productIds.indexOf(id));
for (var f in data) {
row.setDataValue(f, data[f]);
}
}
I guess I should set the cell style somewhere, but I'm not sure where.
UPDATE: According to this page https://www.ag-grid.com/javascript-grid-data-update/#flashing I should do this:
"If you want to override how the flash presents itself (eg change the background color, or remove the animation) then override the relevant CSS classes."
Anyone knows how to do this?
I almost got this now. The answer I found out is based on CSS. Set the classname for blinking/stop-blinking like:
return (<div key={Math.random()}
className={some logic to set classname here, like "blink-red" or "blink-blue"}
onAnimationEnd={() => this.setState({ fade: false })}
> {this.state.value} </div>);
and use onAnimationEnd to set some state variable that will affect that logic.
Then add the fading logic like this to CSS:
.blink-red {
animation: redtotransparent 3s ease 5s;
}
#keyframes redtotransparent {
from {
background-color: red;
color: white;
}
to {
background-color: transparent;
color: black;
}
}
It's still not perfect, but almost there. Changing the key makes React think the DOM has changed. When I come up with anything better I will add it here.
Click on the Flashing Cell option in the dropdown at the top and then you can choose a different color for an up change and a down change. you can also set how long it will flash for.

Animate Angular-flash Alerts

Using the package, Angular-flash and having issues adding custom animations to the showing and hiding of an alert.
From the docs
If you want to use animations, include ngAnimate module. You can then
use regular Angular animation technique for applying your own
transitions.
.alert {...}
.alert.ng-enter, .alert.ng-enter.ng-enter-active {...}
.alert.ng-leave, .alert.ng-leave.ng-leave-active {...}
I feel like I've tried all possible combinations but struggle to get the in . out effects.
My HTML
<flash-message>
<div>{{ flash.text }}</div>
</flash-message>
<button ng-click="showFlash()">PRESS ME</button>
Controller
$scope.showFlash = function() {
var message = '<strong>Hello!</strong> ';
var id = Flash.create('info', message, 4000, false);
};
Just to test my CSS animation is working I just added an animation to the alert class. This provides the show animation only.
.alert {
animation: 1.5s zoomIn ease;
}
I need to be able to attach it to the "Alert Show Event" and then attach a zoom out to the "Alert Hide Event", allowing a specific show and hide effect.
I've tried these in multiple combinations but struggle to find what class to associate with the show / hide animations.
.alertIn,
.alertOut
.alert.ng-hide-add-active
.alert.ng-hide-remove-active
Thanks
I developed a flash message package and uploaded it in npmjs.com, i think the package will help you,

Event propagation does not happen like standard html

I know that react uses its own synthetic implementation of events. However it appears to me that they are not exactly like standard html and this is a problem. In my case I have a checkbox that is a sibling of some img tags. There are two img tags, one for representing checked and another unchecked. I have some css styling that does a display none when the checkbox is in an unchecked state. Trying to get this html/css working with react is hard. It appears that the click event is not propagating onto the checkbox sibling with a react component, although it works from standard html. Note as there's some confusion I know that the non-react version of this is using css and not events. But I'm trying to implement a react evented version of the same thing, and was expecting normal html event propagation behavior--which I'm not seeing. Also note the checkbox is a sibling of the label. It's also transparent, so the user never actually clicks on the checkbox they click on the img tags.
.checkbox-image input[type="checkbox"] + label img.selected {
display: none;
}
.checkbox-image input[type="checkbox"] + label img.unselected {
display: block;
}
<div class="checkbox-image"><input id="portfolio-standard-dev" type="checkbox" data-name="PortfolioStandardDeviation"><label for="mp-chart3"><img class="unselected" src="/images/img-843599.png"><img class="selected" src="/images/img-1b9f30.png"><span>Portfolio Standard Deviation</span></label></div>
CSS has nothing to do with events. An event propagation cannot impact your styles.
You have to handle when the user check/uncheck the checkbox and manually update the class of the image.
Or you can try the following pure CSS:
.checkbox-image input[type="checkbox"]:checked + label img {
display: none;
}
.checkbox-image input[type="checkbox"] + label {
display: block;
}

how can I create a directive that resets value in dropdown?

I have built a tabcontrol with a colors dropdown directive for each tab. I want to reset the dropdownvalue in all the tabs in one go. This is the directive:
<button class="btn btn-warning" ng-click="colors=' ' "></button>
How can I make it reset the colors value?
Plunkr: http://plnkr.co/edit/AasWSJzBWib4aRZuAoBv?p=preview
I edited your plunker a little bit by moving the script into a seperate js-file for readability.
I also moved the button inside the div in which your tabs are in so that it inherits the scope and shares the same controller.
Inside the TabCtrl I added a function which resets the colors property. You can do it either by setting the color to an empty string or deleting the color property. Choose what you prefer.
$scope.resetColors = function () {
for (i=0;i<$scope.tabs.length;i++) {
delete $scope.tabs[i].color;
//$scope.tabs[i].color = ""; --Optional instead of the above
}
}
Hopefully this solution works for you.

Mark form as unsubmitted in AngularJS

In AngularJS, is there a way to mark a form that has already been submitted as unsubmitted (so it loses the ng-submitted class?
Background:
In my css, I'm using the angular validation classes to accomplish the following:
Initially, all inputs have a normal border color.
If the user modifies an input to have an invalid value, set the border color to red.
If the user clicks the submit button, set the border color of all invalid inputs to red.
I am accomplishing this like so:
input.ng-dirty.ng-invalid, .ng-submitted .ng-invalid {
border-color: #F00;
}
That works fine. Now I have a form that submits an asynchronous request, and if the server responds with a success status, I want to clear the form (and effectively reset it to its original state). The problem is when I clear the form, it still has the .ng-submitted class, so all of the required fields have a red border. However I want them all to have a normal border.
I should be able to mark all of the fields as pristine using $setPristine(), but I don't see any way to mark the form as unsubmitted. Is this possible, or do I need to create and maintain my own class for doing this?
You can reset your form and thus mark it as unsubmitted using the following piece of snippet.
Html:
<input type="button" ng-click="reset(form)" value="Reset" />
Angular Script:
$scope.reset = function(form) {
if (form) {
form.$setPristine();
form.$setUntouched();
}
$scope.user = angular.copy($scope.master);
};
