Tell ngAnimate to only animate ngShow/ngHide - angularjs

I have an AngularJS 1.2.2 web application with a <div> that I show/hide based on some $scope property. Using the ngAnimate module, I animate the showing and hiding of the <div>.
<div id="square" ng-show="showSquare" class="animate-shiny"></div>
I also have a class I want to place on this <div> and for this I use ngClass.
<div id="square" ng-show="showSquare" class="animate-shiny" ng-class="{ cool: extraCool }"></div>
And as it so happens, sometimes that class gets applied at the same moment as when the <div> is shown/hidden. This causes the show/hide animation to not work anymore, apparantly it finds ngClass more interesting to animate, even though I don't want to use ngAnimate for that animation.
Here's a Plnkr that demonstrates the behavior. Clicking the show/hide button works great, clicking the make cool button works great, but the button that combines these two causes the show/hide animation to break.
How do I fix this? And can I do it without manually addressing $animate?
Thanks in advance!

The problem is that you are trying to animate using the class and not discriminate between when things should animate. That is, your transition effect applies to the class in general, which ng-animate perceives as having to do work whenever that class is referenced. I modified your css a bit to get pretty close, if not exactly, what you want:
#square {
width: 50px;
height: 50px;
background-color: blue;
transition: 0.4s all ease-out;
}
#square.cool {
box-shadow: 0 0 10px 3px green;
background-color: lightgreen;
}
#square.ng-hide-add, #square.ng-hide-remove
{
display: block !important;
}
#square.ng-hide-remove, #square.ng-hide-add.ng-hide-add-active{
margin-left: -80px;
opacity: 0;
}
#square.ng-hide-remove.ng-hide-remove-active, #square.ng-hide-add{
margin-left: 0;
opacity: 1;
}
Here is the new plunkr so you can play with it: http://plnkr.co/edit/a7wiZfCrEGCXfIDSvF9r?p=preview
If you want to ONLY animate the show/hide and do not want a transition for the color, simply move the transition to the #square.ng-hide-add, #square.ng-hide-remove declaration.

background color does not change with ng-class condition in angularjs

All other css element working fine rather background-color and color.
<md-button class="md-raised" ng-style="style1"
ng-click="style1=style; style2=null;style3=null;style4=null;removable=0;loadPorcessBarcodes();Head.ProcessMode=1"
ng-class="{'selected-btn': Head.ProcessMode == 1}">Auto Nozzle From Stock</md-button>
My css:
.selected-btn {
padding: 2px;
font-size: 20px;
color: #ffffff;
background-color: #122b01;
}
It seems as you've been using ng-style, which is already applying background-color and color style. So even though you apply a class over it with the overridden property, the same element would not reflect, because inline CSS takes first preference. If you wanted to enforce background-color and color properties to be enforced then mark them as !important to see the expected behavior.
Other better way to solve this problem would moving style1 to new class and apply it using ng-class with its appropriate expression.

ng-animate and ng-if cause transition not to played in Internet Explorer

I have a simple div which has a transition. It transitions from a yellow background to a red one.
<div class="foo" ng-class="{'foo-visible': vm.visible}">
The transition is played once the foo--visible class is added to the div.
This works fine in Chrome, IE...etc.
However once I add a wrapper div around it, the transition stops working in Internet Explorer (tested with IE10).
<div class="foo--wrapper" ng-if="vm.visible">
<div class="foo" ng-class="{'foo--visible': vm.visible}">
</div>
I need to include ngAnimate in this case. Then it works in Chrome, but in IE I immediately get the red div, the transition is never played. No transitionstart (IE only) or transitionend events are fired.
Here's a plunker illustrating the issue:
http://plnkr.co/vpJzudnLxTwoJGZoZaNd
Does anybody have an idea what is causing this?
This plnkr adds two similar boxes to yours. http://plnkr.co/edit/lkyWHu?p=preview
<div ng-if="vm.visible">
<div class="animate-box animate-if">
<h2>Inner Class</h2>
</div>
</div>
<div class="animate-box animate-if" ng-if="vm.visible">
<div>
<h2>Outer Class</h2>
</div>
</div>
The "Outer" works in both IE and Chrome.
Chrome iterates the child animation for "Inner" in a way that makes sense. Internet Explorer, as for your example, does not.
On closing, neither do the child animation because the delay to remove the parent is zero.
An interesting point though, IE and Chrome appear to work the same for the authoritative answer at https://docs.angularjs.org/api/ngAnimate/directive/ngAnimateChildren
The CSS I used was:
.animate-box {
height: 100px;
width: 100px;
background-color: red;
}
.animate-if.ng-animate {
transition: all 3s linear;
}
.animate-if.ng-enter,
.animate-if.ng-leave.ng-leave-active {
background-color: yellow;
opacity: 0;
}
.animate-if.ng-leave,
.animate-if.ng-enter.ng-enter-active {
background-color: red;
opacity: 1;
}

How to style striped rows
There are two ways to do this. One is pure CSS using the :nth-child(even) or (odd) pseudo classes. You can add a class to your row and just use style it how you want, such as:
my-class:nth-child(even) .col {
background-color: blue;
}
But I did it differently to teach you something about ng-repeat. Yes, it's for a loop, but it has a bunch of special properties that it exposes for you. Two in particular are $odd and $even. As you might expect, $odd returns true if it is an odd iteration and $even is true when the index is an even number.
So, you can use these with ng-class as part of your expression. Here, I'm adding a class of odd-row:
<div class="row" ng-repeat="column in displayData | orderBy: sortval:reverse | filter: query" ng-class="{'odd-row':$odd}">
Then to make the styles, I added the following rule. I applied the background-color to the .col children so that the background would be contained within the borders that are applied on the .col elements.
.odd-row .col {
background-color: #eee;
}
EDIT:
Actually, you are correct, ng-style would be a third-way, but it doesn't apply a class, it applies inline styles. Therefore, you need to pass it an object with you styles, so for example (simplified):
ng-style="{'color': 'red'}"

How can I fade in and out the visibility of a DIV using ng-show with AngularJS 1.3 beta?

My code looks like this:
<div class="block-border"
data-ng-show="qty > 0">
xxx
</div>
I know there have been a lot of changes with Animation in AngularJS. Can someone tell me the easiest way for me to make it take 500ms to show and 50ms to hide the xxx when the value of qty changes. Note that I am using the very latest AngularJS.
Reference angular-animate.js
Add ngAnimate as a dependent module:
var app = angular.module('app', ['ngAnimate']);
Pick a name for your transition, for example 'fade', and then define the appropriate CSS classes based on the naming convention described in the documentation:
.fade.ng-hide {
opacity: 0;
}
.fade.ng-hide-remove,
.fade.ng-hide-add {
display: block !important; /* or inline-block, as appropriate */
}
.fade.ng-hide-remove {
transition: all linear 1000ms;
}
.fade.ng-hide-add {
transition: all linear 500ms;
}
Add the class to your element:
<div class="block-border fade" ng-show="qty > 0">
Demo: http://plnkr.co/edit/HWi0FfDOsHeSOkcrRtN2?p=preview
I couldn't get the accepted answer to work, but the following did work (taken largely from this ng-nuggets post):
.fade {
transition: all linear 500ms;
opacity: 1;
}
.fade.ng-hide {
opacity: 0;
}
and then my HTML element which I wanted to fade in and out looked something like this:
<span data-ng-show="copyLinkClicked" class="fade">some text here</span>
As #MichaelNguyen mentioned, Bootstrap does appear to have a style already called fade, and we are using Bootstrap in our application, yet the above styles worked nonetheless. If you already have a style named fade, then change the name to something unique before using the above code.
If you want to fade in using ng-if as a boolean angular has some nice documentation here https://docs.angularjs.org/api/ngAnimate . I used ng-if for my fading purposes here's an example below:
form.html
<form name="exampleForm" ng-submit="submit()">
<input type="email" placeholder="Email Address" ng-model="email" required>
<input type="text" placeholder="Name" ng-model="name" required>
<input class="invalid-btn" ng-if="exampleForm.$invalid" type="submit" value="Invalid" />
<input class="valid-btn" ng-if="exampleForm.$valid" type="submit" value="Valid">
</form>
form.css
/* css for button that will show when form is invalid */
.invalid-btn {
border: 1px solid #222;
width: 100px;
height: 50px;
color: #222;
background: #fff;
}
.invalid-btn.ng-enter {
opacity: 1;
}
/* The finishing CSS styles for the enter animation */
.invalid-btn.ng-enter.ng-enter-active {
opacity: 0;
}
.valid-btn {
width: 100px;
height: 50px;
background: #F26623;
color: #fff;
}
/* The starting CSS styles for the enter animation */
.valid-btn.ng-enter {
transition:0.5s linear all;
opacity: 0;
}
.valid-btn.ng-enter-stagger {
/* this will have a 100ms delay between each successive leave animation */
transition-delay: 0.3s;
/* As of 1.4.4, this must always be set: it signals ngAnimate
to not accidentally inherit a delay property from another CSS class */
transition-duration: 0s;
}
/* The finishing CSS styles for the enter animation */
.valid-btn.ng-enter.ng-enter-active {
width: 100px;
height: 50px;
background: #F26623;
color: #fff;
opacity:1;
}
The way this works is if you want to fade in a button with a different color or text and different text color you can fade in a button when the form is filled out and valid and the invalid button will fade out leaving only one button depending on the state of the form. Kind of a hack but it works and looks smooth. I had to set a delay using .ng-enter-stagger because loading the animations at the same time was causing the buttons to blink and jump and not animate smoothly. So in this case we let invalid button hide first then load valid button when form is valid and all input fields have been filled out correctly.

Puzzled: Responsive header with special resizing through pure HTML/CSS?

We have a solution utilizing JavaScript, but I'm also curious if there is a way to do this with pure CSS?
The Situation
I'm relatively new to responsive design, and in the past have stuck with positioning, etc to achieve my layouts. I'm attempting to create a simple responsive header that resizes in a specific way.
My Dilemma
The header is a 29px high bar at the top of the page, with 29x29 buttons at either end. In the middle, bordering the button on the right, is a div (for page titles) that I want to have a min width of 300, but I also want it to expand with the browser width.
Here is the catch: I want this title div to pull away from the left button, leaving a gap of a max-width of 200px. Once the max-width of the gap is reached, I would like the title div to start expanding, staying pressed up against the right button. See as follows.
note: I've created a jsfiddle here for experimenting
I've modified your JSFiddle and added a bit of JavaScript to get the effect I think you're looking for. There are also comments to walk you through exactly what the JS code is trying to accomplish.
Essentially, I'm binding a handler to the window.resize event, calculating the available space in the header, and adding or subtracting from the title container to maintain its width.
Okay well here is what I have so far. WILL EDIT in the morning (kind of tired)
I feel this is definitely possible but it does require javascript. The fact that you want there to be a 200px space available requires javascript or some sort of programming to tell the styling to do that.
<!DOCTYPE html>
<html>
<style>
html, body { height: 100%; }
#container { margin-top: 29px; }
header { height:29px; margin: 0 49px; background-color:#999999; }
#div1 { width: 29px; height: 100%; background-color: yellow; display: inline-block; }
#div2 { width: 100%; height: 100%; background-color: blue; display: inline-block; }
#div3 { width: 29px; height: 100%; background-color: red; display: inline-block; float: right;}
#div4 { height: 100%; background-color: yellow; display: inline-block; float: right; }
</style>
<body>
<div id="container">
<header>
<div id="div1">div1</div><div id="div2">div2</div><div id="div3">div3</div><div id="div4">div4</div>
</header>
</div>
</body>
<script>
if (parseInt(document.getElementById("div2").clientWidth) >= 200) {
document.getElementById("div2").style.width = "200px";
}
</script>
</html>
So the way I went about it is rather than having 3 divs, I made 4 -- the original 3 you had, but then the white space you want to consider as, well open space, I made a div for that as well. I also have javascript so that when the window scales past a width of 200px, it will lock it at that width. Unfortunately, I'm not super polished with my CSS yet so I'm still trying to figure a way to get that working. If anyone wants to edit my answer, please feel free.
Another thing to point out is that while the javascript does working for if the nav is growing, it doesn't for shrinking. I didn't implement a way for it to be able to shrink if say the user decided to shrink his window size because I have it set to lock the width at 200px (I guess a way to work around that would be with an } else { clientWidth = "100%"? Not sure. Hope this gets you on the right track though.
