Cascading Style Sheets
Hi everyone,
Just a quick post on how to override the background color and hover effects for buttons in material ui:
Define your class as follows:
const styles = theme => ({
...
greenButton: {
backgroundColor: green[500],
color: '#FFF',
'&:hover': {
backgroundColor: green[400],
color: '#FFF'
}
}
Then just reference it as you normally would:
const styles = theme => ({
const { classes } = this.props;

Hey everyone,
Coming from Rails I’d grown quite fond of flash messages. Unfortunately there isn’t a built in way of doing this in MVC4. Luckily, there’s a five minute solution posted on StackOverflow: http://stackoverflow.com/a/11809178/522859
Once implemented, it works just like in Rails:
this.Flash("We need you to login before you can edit anything.", FlashEnum.Warning);
Definitely worth checking out if you’ve got time, even more so if you’ve come over from Rails!
Hey everyone,
I ran into a bit of an issue today with my stylesheet conflicting with Bootstrap. After a bit of tinkering I realised that all I really needed from bootstrap were the Carousel styles. I’ve taken everything else out and included everything that’s left below:

Hey everyone,
Just another small directive. This one adds a random class from the provided array to the element.
Check out this fiddle to see the demo: http://jsfiddle.net/uvSVj/3/
I used this directive to add a random background to each of my wrapper divs:
To use it in your app simply define a list of classes in your controller:
app.controller("MyCtrl", function MyCtrl($scope) {
/* A random class is picked from this list */
$scope.classes = [
//"bg-buildings",
"red",
"blue",
"yellow",
"green",
"orange",
"black",
"purple"
];
});
Then add the directive to your page (can be an existing element):
A random class will then be selected from the list and appended to the elements current list of classes (if any).
The easiest way to see how it’s done is probably just to check out the fiddle above, but there’s a code dump below if you need it:
The Random Class Directive
app.directive("ngRandomClass", function () {
return {
restrict: 'EA',
replace: false,
scope: {
ngClasses: "="
},
link: function (scope, elem, attr) {
//Add random background class to selected element
elem.addClass(scope.ngClasses[Math.floor(Math.random() * (scope.ngClasses.length))]);
}
}
});

Hey everyone,
I’ve been mucking around with directives for that last few days and one of my requirements has been a simple timepicker. Nothing too fancy, but if anyone would like to use it – feel free.
See the following fiddle for the demo: http://jsfiddle.net/LFB3F/2/
The directive is initialised with both the hour and minute defaults being set like this:
Note that hours and minutes should be set in the controller that wraps around the Timepicker:
app.controller("MyCtrl", function MyCtrl($scope) {
$scope.hours = 11;
$scope.minutes = 45;
});
The hours and minutes will then be updated whenever the user changes the value. If you need any other hooks it’s fairly easy to modify and there are a heap of comments.
You may also want to put the HTML in an external template. Just make the following changes to the directive (note templateURL):
app.directive("ngTimeSelector", function () {
return {
restrict: 'EA',
templateUrl: '/Directives/TimeSelector',
scope: {
hours: "=",
minutes: "="
},
replace: true,
link: function (scope, elem, attr) {
...
...
The JSFiddle is probably the easiest way to see how it all works. You can simply copy it from there to your app. Alternatively, I’ve dumped the code below:
Uncondensed HTML (for those who prefer to use a template)
{{displayHours()}}{{displayMinutes()}}= 12" class="display"> PM<div ng-if="hours AM

Hey everyone,
Just another quick AngularJS post. This one is for using ng-class with ng-repeat. The goal here is to have a class applied to the non-selected elements. To start with, we’ll chuck the following in our controller:
$scope.transmission = {
selected: null,
options: [
{
name: 'Any'
},
{
name: 'Manual'
},
{
name: 'Automatic'
}
]
};
Here we’re just creating a few random objects. To keep things simple we’re going with transmission types: a manual car, automatic or any. Next you’ll want to add the markup:
......
Finally the class to be applied:
.line-through{
text-decoration: line-through;
}
Hey everyone,
I’ve just starting using Angular and went to do a few animations. I had a bit of trouble trying to find anywhere that mentioned what each class does. This is the demo we’ll be making, it’s pretty basic but hopefully enough to get you started: JSFiddle Demo
Dummy Page
To start with, just create a new page with the following. Note that none of the stuff below applies to the animation itself, this is just so that we’ve got something to work with.
Test Animation//ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.min.js //Initialisation stuff, note that you don't need any of this for animations, just using it so there's something to see function PeopleController($scope){ $scope.name = ""; $scope.people = [ { name: "Santa Clause"}, { name: "Easter Bunny"}, { name: "Tooth Fairy"}, { name: "Chris Owens"}, { name: "Phillip Farnsworth"}, { name: "Clark Kent"}, { name: "Lana Lang"} ]; $scope.removePerson = function(row){ $scope.people.splice(row, 1); } $scope.addPerson = function(){ $scope.people.push({name: $scope.name}); $scope.name = ""; } }Add{{person.name}}
Adding the ng-animate Directive
The first step to adding the transitions is to add the ng-animate directive:
{{person.name}}
Classes for Adding a New Element
Now we’re going to add the styles that are used when a new element is added to the page. To start with, you’ll want to create .person-enter. This is the class that will be animated from. In this instance we want new elements to start off invisible so we’ll set the opacity to 0.
.person-enter{
-webkit-transition: 1s linear all;
-moz-transition: 1s linear all;
-ms-transition: 1s linear all;
-o-transition: 1s linear all;
transition: 1s linear all;
opacity: 0;
}
Next we’ll want to add the styles for .person-enter.person-enter-active. These will be the styles that we want to animate to. Because we’re going from invisible to visible we’ll adjust the opacity:
.person-enter.person-enter-active{
opacity: 1;
}
Classes for Removing an Element
Now we’ll add the class to animate from. This will the opposite of what we used when adding an element – start visible, go to invisble:
.person-leave{
-webkit-transition: 1s linear all;
-moz-transition: 1s linear all;
-ms-transition: 1s linear all;
-o-transition: 1s linear all;
transition: 1s linear all;
opacity: 1;
}
And finally the class to animate to when an element is removed:
.person-leave.person-leave-active{
opacity: 0;
}
All Together Now
Finally we can put the whole thing together. The people boxes should now fade out and in whenever an element is added or removed. You can see it in action here: JSFiddle Demo
Test Animation
.person{
padding: 20px;
width: 50px;
height: 50px;
background-color: #E8FCE4;
border: 1px solid #C0E2BB;
float: left;
margin: 5px;
text-align: center;
box-shadow: 2px 2px 2px #DAD3D3;
text-shadow: 0px -1px 1px #FFF;
cursor: pointer;
}
/*
Note: you can condense these, however they've been split to make the explanation a little easier to follow;
*/
/* This is the class that will be animated *FROM* when a new person is added */
.person-enter{
-webkit-transition: 1s linear all;
-moz-transition: 1s linear all;
-ms-transition: 1s linear all;
-o-transition: 1s linear all;
transition: 1s linear all;
opacity: 0;
}
/* This is the class that will be animated *TO* when a new person is added */
.person-enter.person-enter-active{
opacity: 1;
}
/* This is the class that will be animated *FROM* when a person is removed */
.person-leave{
-webkit-transition: 1s linear all;
-moz-transition: 1s linear all;
-ms-transition: 1s linear all;
-o-transition: 1s linear all;
transition: 1s linear all;
opacity: 1;
}
/* This is the class that will be animated *TO* when a person is removed */
.person-leave.person-leave-active{
opacity: 0;
}
Add
{{person.name}}
//ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.min.js
//Initialisation stuff, note that you don't need any of this for animations, just using it so there's something to see
function PeopleController($scope){
$scope.name = "";
$scope.people = [
{ name: "Santa Clause"},
{ name: "Easter Bunny"},
{ name: "Tooth Fairy"},
{ name: "Chris Owens"},
{ name: "Phillip Farnsworth"},
{ name: "Clark Kent"},
{ name: "Lana Lang"}
];
$scope.removePerson = function(row){
$scope.people.splice(row, 1);
}
$scope.addPerson = function(){
$scope.people.push({name: $scope.name});
$scope.name = "";
}
}
Problems
If you’re having issues, one of the first things to check is that you’re on the right version of angular. There have been a lot of changes and many of the styles used in one this version don’t seem to work in the older ones. If there’s anything else that’s not working let me know!
Where to From Here?
There’s heaps more that nganimate can do, make sure you checkout http://www.nganimate.org/.
Hey everyone,
Just a quick post on how to create a dropdown button using Twitter Bootstrap. It’s pretty straight forward, once you’ve included all your CSS etc just add the following code:
Once you save that you should see something similar to the image below:
To change the text alignment of this list items, all you need to do is adjust the text-align style assigned to the wrapper div.
Once again, this is fairly simple, all you need to do is switch the button type. For instance, if you were after an orange button, you can swap btn-success with btn-warning. A list of the default styles is available on the Twitter Bootstrap site.
Let me know if you have any issues.
