I am calling error-stuff directive in my view as below and i am trying to override the directive's padding 15px to 0px in my view which is not working. So my div1's value and div2's values are not in a straight line since div2 takes more padding in my view.
Error:
Oops !!! Its look like something going wrong !!! Please try again later ...
<div id="div1" class="row">
<div class="pull-left">
<span>Error :</span>
</div>
<div id="div2" style="padding:0px; vertical-align:top">
<error-stuff></error-stuff>
</div>
</div>
The html template on the error-stuff directive as below
<div class="error-class">
<span>Oops !!! Its look like something going wrong !!! Please try again later
... </span>
</div>
in my app.css
.error-class
{
margin-bottom:20px;
padding:15px;
box-sizing:border-box;
line-height:1.5;
font-size:15px;
}
So how do i make div1 and div2 content in straight line by overriding the directives padding:15px to padding:0px?
Assuming error-stuff is used somewhere else and you can't change the global css, in this case you can use a targeted override by specifying the parent in css
#div2 .error-class {
padding: 0;
}

I am building an application using Ionic (version 1) and would like to hide a div from the controller when the user is scrolling. I am stuck and don't know where to start.
This is my code:
<body ng-app="starter" style="padding-top:150px;">
<div ng-controller="AppCtrl" id="header" >
<div class="bar-aaa">
<div class="myLogo">
<img src="img/images/logo.png" style="display: block;margin-left:auto;margin-right:auto;height:50px;margin-top:10px;margin-bottom:30px;" alt=""/>
</div>
<div class="row" style="padding-bottom: 0px;">
<div class="col col-33" style="border-bottom: 2px solid {{oneLine}};margin-bottom: 0;height: 59px;"><img src="{{one}}" style="display: block;margin-left:auto;margin-right:auto;" alt=""/></div>
<div class="col col-33" style="border-bottom: 2px solid {{twoLine}};margin-bottom: 0;height: 59px;"><img src="{{two}}" style="height:17px;display: block;margin-left:auto;margin-right:auto;" alt=""/></div>
<div class="col col-33" style="border-bottom: 2px solid {{threeLine}};margin-bottom: 0;height: 59px;"><img src="{{three}}" style="height:17px;display: block;margin-left:auto;margin-right:auto;" alt=""/></div>
</div>
</div>
</div>
<span ng-show="loading" style="position: absolute;z-index: 99999;margin-left:-75px;top:150px;left:50%;right:50%;background:rgba(0,0,0,0.5);text-align:center;padding:15px;width:150px;" >
<div>
<ion-spinner icon="spiral"></ion-spinner>
<h5 style="color:#fff;">Processing...</h5>
</div>
</span>
<ion-nav-view></ion-nav-view>
</body>
Your question does not explain which <div> you are trying to hide and what code you have tried to use already, but can you assign a function to the on-scroll directive of the ion-content and do whatever you want to do in that function. So like this:
<ion-content on-scroll="scrollFunction()">
And then in your controller add a function called scrollFunction or preferably something more descriptive.
$scope.getScrollPosition = function() {
// Here you can do whatever you want when someone is scrolling.
}
You could for example update a variable in this function and assigned that variable to the ng-show of the <div> you want to show or hide.
To answer your other question regarding why the getScrollPosition() function keeps returning 0. It is a known issue, you can find similar reports here. I am not entirely sure why this happens, but it seems like Ionic is grabbing the scroll position of a different view causing it to stay 0. You can solve this by assigning a delegate-handler to your <ion-content>, which basically gives you an unique identifier to work with. It would look something like this:
<ion-content delegate-handle="scrollHandler" on-scroll="getScrollPosition()">
And then in your controller, instead of doing the following:
$ionicScrollDelegate.getScrollPosition().top;
You need to do this:
$ionicScrollDelegate.$getByHandle("scrollHandler").getScrollPosition().top;
That should solve the issues you are experiencing.
I've been tinkering around a bit with AngularJS and the Ionic framework. Now I would like to display 12 buttons inside a popup. I have this all working, but I would like the buttons to switch appearance when they got pressed.
html
<label>
<p>Fill in catergory name</p>
<input type="text" placeholder="Rent">
</label>
<br />
<br />
<div class="row">
<div class="col col-25"><button class="button button-outline" id="button12in" ng-class="button12 ? 'button12in' : 'button12inpress'" ng-click="button12 = !button12">
</div>
</div>
As you can see I've been trying with button 12.
app.js
$scope.button12 = false;
css
#button12in {background-color: #51FF00;}
#button12inpress{border-style: solid; border-color: black; border-width: 4px;background-color: #51FF00;}
So the idea is that clicking on the button will change the state of $scope.button12. The result of this would be that via the ng-class the button will change style! but for some reason, this is not possible. It picks up the changed state of button12 but the ng-class isn't working in all kinds of syntax I've tried
I think it should be
ng-class="{'class': trueOrFalse}"
To apply different classes when different expressions evaluate to true:
<div ng-class="{class1 : expression1, class2 : expression2}">
Hello World!
</div>
To apply multiple classes when an expression holds true:
<!-- notice expression1 used twice -->
<div ng-class="{class1 : expression1, class2 : expression1}">
Hello World!
</div>
or quite simply:
<div ng-class="{'class1 class2' : expression1}">
Hello World!
</div>
Notice the single quotes surrounding css classes.
or check this Adding multiple class using ng-class
Don't use your flag directly on $scope , but rather try setting the flag on an object on $scope
Example
Use $scope.flagContainer.button12 instead of $scope.button12
$scope.flagContainer = {
button12 : false
}
Now change it view accordingly
I am not able to understand how the ngAnimate works exactly. here is my doubt.
1) ngAnimate - only works on directives?
2) how to make ng-animate work without the directive
3) Any of above way, how to add call back after animation complete?
Because i see all the animation examples only with directives.
I have a small demo here, any one help me to animation both without directive and with directive approach to simply adding a class name as `fade'?
my CODE:
<div class="container" ng-app="myApp">
<div class="content" ng-controller="count">
<h1 ng-click="animate()">Click ME</h1>
<h2>Let me Fade</h2>
</div>
</div>
<div class="container" ng-app="myApp">
<div class="content" ng-controller="count">
<h1 ng-click="animate()">Click ME</h1>
<h2>Let me Fade</h2>
</div>
</div>
Demo to update
I am not able to understand how the ngAnimate works exactly. here is
my doubt.
ngAnimate is a module that provides support for animations in angular apps. There are two ways to make use of animations when ngAnimate is used: by using CSS and JavaScript. For CSS based animations, angularjs adds a class ng-enter/ng-leave whenever an element is shown/removed from 'view'. You simply need to play with these classes to make the animation work!
Prerequisite:
You would need to add the library for angular-animate
<script src="ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular-animate.js">
</script>
and include ngAnimate as the dependency in your myApp module.
var myApp = angular.module('myApp', ['ngAnimate']);
1) ngAnimate - only works on directives?
Yes. You cannot use ngAnimate without directive.
According to documentation, following directives are "animation aware":
ngRepeat, ngView, ngInclude, ngSwitch, ngIf, ngClass,
ngShow, ngHide, ngModel, ngMessages and ngMessage
2) how to make ng-animate work without the directive
You cannot!. Remember, even ng-click is a directive
3) Any of above way, how to add call back after animation complete?
Yes, You can add a callback after the animation is complete using the $animate service(which would usually be done in a custom directive) and use $animate.leave(element, [options]);
Have a look at this example for triggering events after the animation ends.
Finally, here is the updated demo you mentioned in question.
You may toggle a flag to true/false with each click on <h1> and make content inside <h2> hide/show based on flag.
<div class="container" ng-app="myApp">
<div class="content" ng-controller="count">
<h1 ng-click="animate()">Click ME</h1>
<h2 ng-if="flag" class="fade">Let me Fade</h2>
</div>
</div>
Also, you'd need to handle fade-effect with css
.fade.ng-enter {
transition:0.5s linear all;
opacity:0;
}
.fade.ng-enter.ng-enter-active {
opacity:1;
}
.fade.ng-leave {
transition:0.5s linear all;
opacity:1;
}
.fade.ng-leave.ng-leave-active {
opacity:0;
}
Hope it helps!
<div class="container" ng-app="myApp">
<div class="content" ng-controller="count">
<h1 ng-click="animate()">Click ME</h1>
<h2 ng-if="clicked" class="animate-if">Let me Fade</h2>
</div>
I added a variable named clicked which is set to true or false to animate the Let me Fade Text
var myApp = angular.module('myApp', []);
myApp.controller('count', function($scope) {
$scope.clicked=false;
$scope.animate = function () {
$scope.clicked=!$scope.clicked;
}
});
In this JS file upon clicking the click me button the variable clicked is set to true or false .
**
h2.fade {
opacity : 0;
transition: opacity 1s ease-in-out;
}
.animate-enter, .animate-leave {
transition: 500ms ease-in all;
position: relative;
display: block;
}
.animate-enter.animate-enter-active, .animate-leave {
left: 0;
}
.animate-leave.animate-leave-active, .animate-enter {
left: 500px;
}
**
Here in the css file i added css for the class animate which acts upon clicked variable if the variable is true it goes for animate-enter-active
otherwise it goes for leave-active
I want use ng-class to conditionally add a class to the accordion-heading, but it appears that not even setting a class explicitly on the element gets preserved. I have this:
<div accordion close-others="true">
<div ng-repeat="currItem in items" accordion-group>
<div accordion-heading class="myClass">My Heading {{$index}}</div>
<div class="accordion-inner myClass">asdf asdf asdf</div>
</div>
</div>
And the fiddle: http://jsfiddle.net/Zmhx5/1/
When I inspect the accordion heading element, the class myClass is nowhere to be found. Is there some reason I can't add classes to the accordion heading?
You can put the CSS inside the directive accordion-heading tags:
<accordion-heading>
<div class="myClass">My Heading {{$index}}</div>
</accordion-heading>
In Angular UI Bootstrap, they have created a directive for accordion-heading. Template for this is written in ui-bootstrap-tpls.js. Try to modify directive for accordion-heading.
I ran into the same issue trying to conditionally apply a background color to the heading with ng-class. This is a bit of a workaround, but it does the trick.
First we need to remove the padding from the heading. If you inspect it, you'll see that it generates a div with a .panel-heading class and a padding: 10px 15px (see note below). The padding is what causes issues when trying to apply a background to a nested div, so lets remove it.
.panel-heading {
padding: 0;
}
Now we can add our nested div and give it the same padding to get back our previous look.
<accordion-heading>
<div class="myClass" style="padding: 10px 15px">My Heading {{$index}} </div>
</accordion-heading>
Here's the updated jsfiddle
Note my code above is from a different version of ui-bootstrap. The classes were slightly different in this jsfiddle, so you will see a slightly different solution. The concept, however, is the same.
you could just apply your CSS to an outer div like this:
HTML:
<div ng-app="myApp" ng-controller="MyCtrl">
<div accordion close-others="true">
<div class="myClass" ng-repeat="currItem in items" accordion-group>
<div accordion-heading>
<div>My Heading {{$index}}</div>
</div>
<div class="accordion-inner">asdf asdf asdf</div>
</div>
</div>
</div>
CSS:
.myClass {
background-color: gray;
color: black;
}
.accordion-inner {
background-color: green;
color: black;
}
JS:
angular.module("myApp", ['ui.bootstrap'])
.controller("MyCtrl", function ($scope) {
$scope.items = [{}, {}, {}, {}];
});
then, change it to use ng-class and it should work just fine
pd: (Sorry about the bad english)
I'm trying to implement a mechanism to hide / show div within a group meaning that I want to only have one div displayed for the group. Of course, I can implement this using the ng-show directive but I would like to have something more generic.
For example:
<div div-group="mygroup">
<div id="div1"> ... </div>
<div id="div2"> ... </div>
<div id="div3"> ... </div>
</div>
If I call a function like showDiv("div1"), other div would be hidden (div2 and div3). I thought about adding an object on the root scope containing all inner div status (displayed or hidden).
Thanks very much for your help!
Thierry
One way could be using ng-class
.show{
display:block
}
.hide{
display:none;
}
<div div-group="mygroup">
<div id="div1" ng-class={true:'show',false:'hide'}[selecteddiv='div1']> ... </div>
<div id="div2" ng-class={true:'show',false:'hide'}[selecteddiv='div2']> ... </div>
<div id="div3" ng-class={true:'show',false:'hide'}[selecteddiv='div3']> ... </div>
</div>
$scope.choose=function(id){
$scope.selecteddiv=id;
}
So you could pass proper id as string in function
If you want to do this in vanilla js, you just can write your showDiv function like this
function showDiv(id) {
//hide all divs
document.findElementById('div1').style.display = 'none';
document.findElementById('div2').style.display = 'none';
document.findElementById('div3').style.display = 'none';
//show just the div you want
document.findElementById(id).style.display = 'block'; //or whatever it was before
}
