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 am trying to create custom pager for ion-slide-box. This is codepen sample
This is my js:
$scope.currentSlide = 0;
$scope.pagerClick = function (index) {
$ionicSlideBoxDelegate.slide(index);
}
$scope.slideChanged = function (index) {
$scope.currentSlide = index;
}
This is html file:
<ion-slide-box does-continue=true show-pager=false on-slide-changed="slideChanged($index)">
<ion-slide class="item-image" ng-repeat="i in getNumber(number) track by $index">
<img src='{{images[$index]}}' />
</ion-slide>
</ion-slide-box>
<div class="page-indicator" ng-repeat="i in getNumber(number) track by $index">
<a class="button" href ng-class="{activated: $index == currentSlide}" ng-click="pagerClick($index)">{{$index+1}}</a>
</div>
Almost all works fine, except one thing. When I click on my pager buttons it doesn't change active button in pager. When I swype slides all buttons change style correctly. I think it may be because of $index - I have two such variables. But I can't understand or fix it.
I finally solved this problem which was because activated is inline class of button.
When I push button this class was applying, but when I unpress button Angular delete this class.
I create my class active-button and all is now working.
<div class="page-indicator" ng-repeat="i in getNumber(number) track by $index">
<a class="button" href ng-class="{'active-button': $index == currentSlide}" ng-click="pagerClick($index)">{{$index+1}}</a>
and css
.active-button{
background-color: #b2b2b2 !important;
box-shadow: none !important;
color: #fff !important;
}
I have a problem. I have Index page where i load different pages in <div ng-view></div>.I have sidebar, so while im waiting that ng-view load page sidebar goes on left side and i dont want that.
In index i have <div ng-view></div> and right side menu:
<div class="col-lg-3 col-md-3">
<div class="right-sidebar">
#foreach (var item in Model.SideAccountBanners)
{
<div class="promo">
<a href="#item.LinkTo">
<div class="image">
<img class="resize" src="#item.BannerPath" alt="" />
<h1 class="title">#MvcHtmlString.Create(Html.Encode(item.Title).Replace("-", "<br />"))</h1>
<p class="description">#MvcHtmlString.Create(Html.Encode(item.Description).Replace("-", "<br />"))</p>
</div>
</a>
</div>
How can i set default size for that <div ng-view></div> or set something like document ready? idk
You should be able to do this with css:
[ng-view] {
min-height: 100%;
}
Something like the above.
EDIT: If you have multiple ng-views you will want to change the css.
I am a noice programmer and new to the Ionic Framework and Angular.js. I am developing a mobile app using Ionic primarily "out of the box". But, I'd like to display an Ionic list that combines a:
checkbox
item content (e.g. string of text)
avatar (i.e. an image associated with the item)
See mockup below...
A streamlined example of the HTML markup looks like this:
<ion-pane>
<ion-header-bar class="bar-stable">
<h1 class="title">Combine Checkbox & Avatar in List</h1>
</ion-header-bar>
<ion-content>
<ul class="list">
<li class="item item-checkbox item-avatar-right">
<label class="checkbox">
<input type="checkbox">
</label>
<img src="http://placehold.it/100x100">
Item #1
</li>
<li class="item item-checkbox item-avatar-right">
<label class="checkbox">
<input type="checkbox">
</label>
<img src="http://placehold.it/100x100">
Item #2
</li>
</ul>
</ion-content>
</ion-pane>
But the page is displayed like so:
My questions:
Does the Ionic Framework support this combination (combining a checkbox and an avatar image in a list item)?
If so, what markup or code (HTML, CSS, JS) can I use to render this type of display?
You can see code with a simple example here:
Plunker Example Code
Appreciate guidance and direction from the Stackoverflow community!
I think that you won't be able to achieve that with Ionic default CSS. Maybe you should work on some css to adjust some positions due to CSS incompatibilities between these elements. However, I could reach something very close to what you showed. Put the following item in your plunker code and give it a try:
<li class="item item-avatar-right item-checkbox">
<img src="http://placehold.it/100x100">
<label class="checkbox">
<input type="checkbox">
</label>
<h2>Headline</h2>
<p>Description</p>
</li>
I was able to combine the item-avatar class with a checkbox by placing the checkbox on the right (using the item-checkbox-right class) and by overriding the min-height with 0.
My HTML:
<ion-content class="list">
<ion-checkbox class="item-avatar item-checkbox-right" ng-repeat="user in connectedUsers">
<img ng-src="{{user.picture}}">
<h2>{{user.name}}</h2>
<p>{{user.email}}</p>
</ion-checkbox>
</ion-content>
I also had to add the following CSS rule:
.item-avatar,
.item-avatar .item-content,
.item-avatar-left,
.item-avatar-left .item-content {
min-height: 0;
}
I got a result like the following:
I was working on a solution for the same problem and i came up with this css class : item-checkbox-img
Just add it to the img tag in your ion-checkbox
You can see the result in this codepen, the image is resized and its absolute position places it to the right of the item
angular.module('ionicApp', ['ionic'])
.controller('MainCtrl', function($scope) {});
body {
cursor: url('http://ionicframework.com/img/finger.png'), auto;
}
.item-checkbox-img {
vertical-align: middle;
position: absolute;
top: 0px;
right: 15px;
height: 100%;
}
<html ng-app="ionicApp">
<head>
<meta charset="utf-8">
<title>Toggles</title>
<link href="http://code.ionicframework.com/1.0.0-beta.14/css/ionic.css" rel="stylesheet">
<script src="http://code.ionicframework.com/1.0.0-beta.14/js/ionic.bundle.js"></script>
</head>
<body ng-controller="MainCtrl">
<ion-list style="height: 2000px">
<ion-checkbox>ion-checkbox
<img class="item-checkbox-img" src="http://placehold.it/350x150">
</ion-checkbox>
<ion-checkbox>ion-checkbox
<img class="item-checkbox-img" src="http://placehold.it/100x100">
</ion-checkbox>
</ion-list>
</body>
</html>
Working with Bootstrap and AngularJS, is there a way to ng-repeat horizontally with a new row for every set amount of elements?
I have been playing around with ng-class to accomplish this Fiddle, but the problem is that I can't get the float left divs within the initial row div... Any thoughts, am I not thinking of something or would this best be done with a Directive?
Here is my code (live example in the above fiddle link):
<body ng-app="myApp">
<div ng-controller="MyCtrl">
<div ng-repeat="num in numbers"
ng-class="{'row': ($index)%2==0, 'col-md-6': ($index)%2!=0}">
<div ng-class="{'col-md-6': ($index)%2==0}">
{{num}}
</div>
</div>
</div>
</body>
var myApp = angular.module('myApp', [])
.controller('MyCtrl', function ($scope) {
$scope.numbers = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10"];
});
.row {
clear: both;
width: 100%;
border: 1px solid red;
}
.col-md-6 {
width: 50%;
float: left;
border: 1px solid blue;
}
If you are working with Bootstrap 3 and AngularJS you can declare a new filter that will return one array of sub array slices and then do two ng-repeat.
It will look like that:
<div class="row" ng-repeat="row in filtered = (arr | splitArrayFilter:3)">
<div class="col-md-4" ng-repeat="n in row">
<h3>{{n}}</h3>
</div>
</div>
app.filter('splitArrayFilter', function() {
return function(arr, lengthofsublist) {
if (!angular.isUndefined(arr) && arr.length > 0) {
var arrayToReturn = [];
var subArray=[];
var pushed=true;
for (var i=0; i<arr.length; i++){
if ((i+1)%lengthofsublist==0) {
subArray.push(arr[i]);
arrayToReturn.push(subArray);
subArray=[];
pushed=true;
} else {
subArray.push(arr[i]);
pushed=false;
}
}
if (!pushed)
arrayToReturn.push(subArray);
console.log(JSON.stringify(arrayToReturn));
return arrayToReturn;
}
}
});
You can Find it on Plunker here: http://plnkr.co/edit/rdyjRtZhzHjWiWDJ8FKJ?p=preview
for some reason the view in plunker does not support bootstrap 3 columns but if you open it in embedded view or in browsers you can see that it works.
It was clever what you were doing with ng-class. I hadn't ever thought of using %2 within the expression there.
But for future reference, there is a slightly easier way to accomplish that: ng-class-even and ng-class-odd. It does the same thing as what you were doing, but just a bit cleaner:
<div ng-repeat="num in numbers" ng-class-even="'md-col-6'" ng-class-odd="'row'">
{{num}}
</div>
But this doesn't resolve your problem. If I understand you correctly, you want a row, with two columns within that row. The easiest way I could think of is to split up the arrays. Put the repeat on the div, then have 2 span within the div. I think one of the issues that you had originally, is that you were repeating a single div, and trying to treat that block element as an inline
Controller
myApp.controller('MyCtrl', function ($scope) {
$scope.evens = ["2","4","6","8","10","12","14"];
$scope.odds = ["1","3","5","7","9","11","13"];
});
HTML
<div ng-controller="MyCtrl">
<div ng-repeat="odd in odds" class="row">
<span class="span3">{{odd}}</span>
<span class="span2">{{evens[$index]}}</span>
</div>
</div>
Fiddle
Being that you're using version 1.1.5, that also opens you up to a new directive: ng-if! You could also use ng-switch to do some conditional logic displays.
You didn't include bootstrap in your fiddle, and for some reason I can't get jsFiddle to display bootstrap. So I created some temp CSS classes that would somewhat resemble bootstraps class="span"
No need to add .row class .. I did this:
HTML:
<div ng-repeat="product in allProducts">
<div class="my-col-50">
<h1>{{product.title}}</h1>
</div>
</div>
CSS:
.my-col-50{float:left;width:50%;}
and it's work like a charm.
Although this isn't the "proper" way of doing this, there is a way to achieve this using CSS.
For example, this is for a 3 column layout:
HTML:
<div class="row">
<div ng-repeat="(key, pod) in stats.pods" class="pod-wrap">
<div ng-if="objectCheck(pod) == false" class="col-md-4 col-sm-4 pod">
<div>
<h2 ng-bind="key"></h2>
<p class="total" ng-bind="pod | number"></p>
</div>
</div>
<div ng-if="objectCheck(pod) == true" class="col-md-4 col-sm-4 pod">
<div>
<h2 ng-bind="key"></h2>
<div ng-repeat="(type, value) in pod track by $index">
<p class="status"><% type %> <small><% value %></small></p>
</div>
</div>
</div>
</div>
</div>
CSS:
.pod-wrap:nth-of-type(3n):after {
display: table;
content: '';
clear: both;
}
I tried two of the suggestions given here...
the one by yshaool works fine but like i commented on it give me that infinite loop error.
Then I tried something like below:
<div class="row" ng-repeat="row in split($index, 3, row.Attempts)">
<div class="col-md-4" ng-repeat="attempt in row">
<div>Attempt {{row.AttemptNumber}}</div>
<div>{{row.Result}}</div>
</div>
</div>
and the function:
$scope.split = function (index, length, attempts) {
var ret = attempts.slice(index * length, (index * length) + length);
console.log(JSON.stringify(ret));
return ret;
}
was going somewhere with that when i realized that it could be as simple as
<div ng-repeat="attempt in row.Attempts">
<div class="col-md-4">
<div>Attempt {{attempt.AttemptNumber}}</div>
<div>{{attempt.Result}}</div>
</div>
</div>
using "col-md-4" does the trick as I only need to split using three columns per row..
(let bootstrap do the work!)
anyway the other answers here were really useful...
Depending upon the number of columns that you need in your template, create chunks of the original data source in your controller.
$scope.categories = data //contains your original data source;
$scope.chunkedCategories = [] //will push chunked data into this;
//dividing into chunks of 3 for col-4. You can change this
while ($scope.categories.length > 0)
$scope.chunkedCategories.push($scope.categories.splice(0, 3));
In your template you can now do the following
<div class="row" ng-repeat="categories in chunkedCategories">
<div class="col-xs-4" ng-repeat="category in categories">
<h2>{{category.title}}</h2>
</div>
</div>
My approach was to use the $index variable, which is created and updated by AngularJS within an ng-repeat directive, to trigger a call to the CSS clearfix hack which, in turn, resets to a new row.
I am using the following versions: AngularJS 1.5.5 and Bootstrap 3.3.4
<!-- use bootstrap's grid structure to create a row -->
<div class="row">
<!-- Cycle through a list: -->
<!-- use angular's ng-repeat directive -->
<div ng-repeat="item in itemList">
<!-- Start a new row: -->
<!-- use the css clearfix hack to reset the row -->
<!-- for every item $index divisible by 3. -->
<!-- note that $index starts at 0. -->
<div ng-if="$index % 3 == 0" class="clearfix"></div>
<!-- Create a column: -->
<!-- since we want 3 "item columns"/row, -->
<!-- each "item column" corresponds to 4 "Bootstrap columns" -->
<!-- in Bootstrap's 12-column/row system -->
<div class="col-sm-4">
{{item.name}}
</div>
</div>
</div>
To keep solution bootstrap formated i solved this using ng-class
<div ng-repeat="item in items">
<div ng-class="{ 'row': ($index + 1) % 4 == 0 }">
<div class="col-md-3">
{{item.name}}
</div>
</div>
</div>
