I would like to use ng-switch because I do not want the other elements that I do not want to show to be part of the DOM. That is why i did not use ng-hide/ng-show. In the example below, I would like to only have the span tag be in the DOM without the div wrappers from the ng-switch. What is the best way to accomplish this?
<div ng-switch on="user">
<div ng-switch-when="true">
<span>One</span>
</div>
<div ng-switch-when="false">
<span>Two</span>
</div>
</div>
You can use the ng-switch directive as a custom element and not specify the div in the first place. For example:
<ng-switch on="user">
<span ng-switch-when="true">One</span>
<span ng-switch-default>Two</span>
</ng-switch>
Here is a plunker to play around with: http://plnkr.co/edit/zni6raUWOguhQh9jDiY3
the solution provided by #ChrisAuer this still creates a wrapping element.
AFAIK you'd have to use a custome directive. You may want to use angular-ui if
<div ui-if="user">
<span>One</span>
</div>
<div ui-if="!user">
<span>Two</span>
</div>
Probably, in your case, you'd be fine using ng-show or ng-hide which only hide(display:none) the element - they don't remove it form the DOM.
<div ng-show="user"> <!-- same as ng-hide="!user" -->
<span>One</span>
</div>
<div ng-hide="user"> <!-- same as ng-show="!user" -->
<span>Two</span>
</div>
I would say use ng-if, like this:
<div>
<div ng-if="user==true">
<span>One</span>
</div>
<div ng-if="user==false">
<span>Two</span>
</div>
</div>
you can use <span> to prevent your html layout changing
because <span> is not like <div>, it won't take up any space.
<span ng-switch="user">
<span ng-switch-when="true">One</span>
<span ng-switch-default>Two</span>
</span>

I have certain tags for tracking events in analytics.
<div class="video"
analytics-event="{{track.event}}"
analytics-category="{{track.category}}">
...
</div>
The thing is that sometimes track.event (or track.category) is empty and I don't want that empty tag in there. <div class="video" analytics-event>...<div>
Is there a way to display them conditionally?
Use ng-if
<div ng-if="track.event" class="video"
analytics-event="{{track.event}}">
...
</div>
if it does not present,
<div ng-if="!track.event" class="video"
analytics-event>
</div>
I have a very simple thing I am trying to do. The ng-click is not working. Any ideas why? Is there a problem with divs that are embedded in another div or am I just too sleepy? That item affected is not included in the code below, but no event is ever registered with the click.
<div ng-switch-when="3" ng-mouseenter="showIcons=true" ng-mouseleave="showIcons=false">
<div ng-if="editPerm" ng-show="showIcons" class="icon_holder" style="width: {{obj.mainwidth}}px;">
<div class="deletebutton"></div>
<div ng-click="equationShow=!equationShow" class="equationspecs"></div>
</div>
<div class="equationBlock">
<div class="eqshow" id="{{obj.itemid}}" ng-show="!obj.showEdit" ng-dblclick="obj.showEdit=!obj.showEdit">
<span mathjax-bind="obj.data.Format_left"></span>=
<span mathjax-bind="obj.data.Format_showequation"></span>=
<span mathjax-bind="obj.data.Format_showsolution"></span>
</div>
If you were able to click on a div with no content in it (sometimes a hard thing to do!), it would simply invert the value of equationShow on the scope.
But that would produce no visible difference. From what I can see in your example, the value of equationShow isn't being used in any way.
Based on your comment, you've probably got a problem with variable scoping.
If, for instance, you did something like this, it'd be more likely to work:
<div ng-init="myVariable = false">
<div ng-if="!myVariable">
<div ng-click="$parent.myVariable = !$parent.myVariable">Show the other div</div>
</div>
<div ng-if="myVariable">
Showing this div
</div>
</div>
I am using metro ui and am trying to use ng-repeat within it to build html within a popup.
My template looks like this. Any thoughts would help. I have verified the data is there, but ng-repeat just doesn't work within double quotes. I've tried using single quotes, but that doesn't work.
Here's my template.
<div class="container">
<div class="title-group six">
<a ng-repeat="product in products"
data-hint="{{product.name}}|<div><ul><li ng-repeat='color in product.colors'>{{color.name}}</li> </ul></div>" href="#/product/{{product.id}}" class="tile bg-violet" data-click="transform" >
<div class="tile-content icon">
<img src="{{product.pic}}">
</div>
<div class="brand">
<div class="label">{{product.name}} </div>
</div>
</a>
</div>
As a start, your HTML is malformed, you need a closing DIV tag on the end.
Also, in your ng-repeat, your variable name should be different to the array. I'd suggest something like:
ng-repeat="p in products" or ng-repeat="product in products"
Hopefully this helps.
I've seen this question and seen it answered but not in any way I can use or understand. The question is very specific and simple but somehow the answers are a bit over my head.
All I want to do is have a very simple menu work. when i menu item is clicked, I need it to of course use my angular controller function to handle it. I want all of that on the angular side. It actually does work when I simply use the elements directly without declaratively making my own.
So this works just fine and my ng-click is successfuly calling my acceptedSelect() in my controller:
<core-menu>
<div ng-repeat="order in acceptedOrders" ng-click="acceptedSelect(order)">
<paper-item class="my-paper-item" >
<div class="order-list-item">
<div class="order-number">{{order.Order}}</div>
<div class="order-date"> {{order.Date}} </div>
<div style="clear: both"></div>
<div class="order-address">
{{order.Property}}
</div>
</div>
</paper-item>
</div>
</core-menu>
But i do the same thing by wrapping the paper element in a polymer-element, it doesn't work. So this will not work:
<polymer-element name="my-app" attributes="refresh">
<template>
<style>
...
</style>
<core-menu>
<div ng-repeat="order in acceptedOrders" ng-click="acceptedSelect(order)">
<paper-item class="my-paper-item" >
<div class="order-list-item">
<div class="order-number">{{order.Order}}</div>
<div class="order-date"> {{order.Date}} </div>
<div style="clear: both"></div>
<div class="order-address">
{{order.Property}}
</div>
</div>
</paper-item>
</div>
</core-menu>
</template>
<script>
Polymer('my-app', {
});
<my-app></my-app>
I'm just not sure what I can do to make this work. Any help is greatly appreciated.
I am a beginner using AngularJS.
I would like to render a collection in my HTML code, with a specific directive: one item at left, the following one at right, the third one at left etc...
<div ng-repeat="Model in Collection">
<!-- The HTML i need for even iterations -->
<div class="col-xs-2.col-sm-2.col-md-2.col-lg-2.col-xs-offset-2.col-sm-offset-2.col-md-offset-2.col-lg-offset-2">
<img alt="Player" src="{{Model.avatar}}" popover-placement="left">
</div>
<!-- The HTML i need for odd iterations -->
<div class="col-xs-2.col-sm-2.col-md-2.col-lg-2.col-xs-offset-8.col-sm-offset-8.col-md-offset-8.col-lg-offset-8">
<img alt="Player" src="{{Model.avatar}}" popover-placement="right">
</div>
</div>
What is the better way to do that ?
You can take advantage of ng-class-odd and ng-class-even to declare the class of the divs.
<div ng-repeat="Model in Collection">
<div ng-class-even="'col-xs-2.col-sm-2.col-md-2.col-lg-2.col-xs-offset-2.col-sm-offset-2.col-md-offset-2.col-lg-offset-2'"
ng-class-odd="'col-xs-2.col-sm-2.col-md-2.col-lg-2.col-xs-offset-8.col-sm-offset-8.col-md-offset-8.col-lg-offset-8'">
<img alt="Player" src="{{Model.avatar}}" ng-class-even="'left'" ng-class-odd="'right'">
</div>
</div>
