I am opening and closing some side (open and close under the title) using angular and I'm wondering if there is a way I can swap between classes When I'm doing this too so I can swap some css. Here's what I'm doing -
<form name="metaDeta" id="lessonDetails" class="lessonItem" ng-controller="detailsController">
<div class="small-12 columns">
<div class="lesonHead lessonHeadOpen saDetailsHead" ng-click="showDetails = ! showDetails" ng-class="myVar">
<h5>Lesson Details</h5>
</div>
<div class="lessonSASlider" ng-show="showDetails">
This works fine for opening and closing the form, however there is a class .lessonHeadOpen that I would like to try and toggle between .lessonHeadClosed. So basically I am looking for something like an addClass/removeClass even on click to toggle between the 2 classes on the element when the user opens and closes it. Is this possible with angular? Could I work off what I have or do I have to re-structure. Thanks!
You can use ng-class to dynamically add classes based on the result of expressions. Read ngClass
<div class="lessonHead" ng-click="showDetails = ! showDetails">
<h5>Lesson Details</h5>
</div>
<div ng-class="{className: showDetails}">
</div>
This directive will evaluate showDetails expression and if true, it will apply the class className
Update:
If I understand correctly, do the same but reverse the expression so if not showdetails add one class and then when show details is true it will be removed and the other class added. <div ng-class="{classOne: showDetails , classTwo: !showDetails}"> SEE FIDDLE
You can use ng-class for toggling.
Simply add a condition for a class to appear and it will based on the condition.
ng-class="{'className': shouldShowClass}"
You can use ng-class's ternary operator notation:
<div ng-class="showDetails? 'lessonHeadOpen': 'lessonHeadClosed'>...</div>

I am using Angular 1.4.7 and need to do the following
<div ng-if="varIsTrue">
<div ng-if="!(varIsTrue)" my-custom-directive>
A lot of content
</div>
So basically, if the div is set only the proper div shows up. I tried do a few variations of this with ng-if and ng-show but I believe because how the browser renders the dom it is messing it up with the multiple divs, but that is the concept I am going for. Does anyone know how I can accomplish this?
You cannot do this you should have 2 closing tags
<div ng-if="varIsTrue">
</div>
<div ng-if="!(varIsTrue)" my-custom-directive>
A lot of content
</div>
or you will have to switch in my-custom-directive
i have polymer template in which i have 3 divs . i want to keep condition on based on name m fetching in expression. How to keep condition for the same.
code is below:
<div class="cySimplifiedContainer isCostLabel">
<span>{{item.id.optnName}}</span>
</div>
<div class="isSummary">
<span class="iSHeader">{{_toMoneyFormat(item.optnCtd)}}</span>
</div>
<div class="isSummary">
<span class="iSHeader">{{_toMoneyFormat(item.optnGoFwd)}}</span>
</div>
<div class="isSummary">
<span class="iSHeader">{{_toMoneyFormat(item.optnTotal)}}</span>
</div>
I need to keep check on item.id.optnName . If it contains KEFH then it should remove _toMoneyFormat function from span.
plz review .
use ng-if in your div. Here i create a simple ng-if example

I'm fairly new to AngularJS and trying to learn by doing.
There is a function in a directive I'm looking to access from the view. What I have in my HTML file is
<div collapse class="collapsed" ng-click="toggle()" ></div>
What's going on there is the toggle() function should be called on click and change the class to expanded, effectively changing the background image described in the CSS. toggle() is inside the collapse directive.
It doesn't seem to be accessing it though and I'm not sure why. Is there another way to do this or actually access said directive from the view? Could you explain why it's not accessing it?
Could this question possibly help? 15672709, it leads to this fiddle and goes beyond in case you nest your directives like below:
<div ng-controller="MyCtrl">
<div screen>
<div component>
<div widget>
<button ng-click="widgetIt()">Woo Hoo</button>
</div>
</div>
</div>
</div>
I'm trying to expand a DIV element on my angular layout. I'm using angular-masonry to give a mason-style to my layout, but now I need to expand those boxes on click. I've tried a lot of stuff, but it kept overlapping my others elements. Soon figured out that I'll have to write it the "angular way" so I don't run into DOM manipulation conflicts.
Here's my code:
<div class="row" masonry>
<div
class="masonry-brick item-component col-sm-4 col-md-4"
ng-repeat="component in components.components | filter : components.filterByFilter | filter : searchText"
ng-click=" // expand #expandable // "
>
<div class="component-wrapper">
<div class="component">
<img ng-src="#{{ component.thumb }}"/>
</div>
<div class="component">
#{{ component.name_en }}
</div>
</div>
<div id="expandable" class="expand-me codes-wrapper">
<p>XXX</p>
<p>YYY</p>
<p>ZZZ</p>
</div>
</div>
</div>
Here's what I want to accomplish in the "angular way": http://codepen.io/desandro/pen/daKBo
In your example (http://codepen.io/desandro/pen/daKBo) if you click on an element there are two things that will be done:
(1) the style of the clicked item is changed
(2) the function masonry is called on the container element that keeps the divs.
I can't see such a function in angular-masonry pre builded. So i'll guess you have to do this by your self. Here are some hints how to solve this (i havn't try it in real)
Bind a function to ng-click. In this function set a state to the current component. This state shoud be used to toggle the css-class of the element. you can use ng-class for this.
The second part is little bit more complex. I would suggest write a direcive 'masonry-change-listener' and bind it to the element that is bound to the same element with the directive masonry. If you click on a component $emit an event, that something has changed. In the directive 'masonry-change-listener' listen to this event. if this event fires you have to call $element.masonry.apply($element) in the link function.
I have this code : http://jsfiddle.net/Qchmqs/BSKrG/
<div class="step"><-- this is darned wrong
<div id="step2"><a>Darn</a></div>
<div id="step2"><a>Darn</a></div>
<div id="step2"><a>Darn</a></div>
</div>
<div class="step"><-- this works fine
<div id="step2"><a>Darn</a>
<a>Darn</a>
<a>Darn</a></div>
</div>
The first block is three links inside three separate divs inside a surrounding div
The bottom block has the links inside one parent div
I am trying to change the background of an active link, but it won't turn off in the upper block.
The script works well with the bottom links but not working as expected with the upper ones
PS : The active class should be toggled only from the Links i have a lot of other scripts in the page that uses the .active links from this list.
For starters, do what JamesJohnson said and remove the multiple IDs. They can only cause you problems down the road.
In the upper links, the a tags aren't siblings because you put each one in its own div. So you need to do this to remove classes from the other as:
$(this).parent().siblings('div').children('a').removeClass('active');
http://jsfiddle.net/mblase75/BSKrG/1/
Unfortunately, that breaks the functionality on the lower links. You can achieve success in both places by adding andSelf to the parent siblings:
$(this).parent().siblings('div').andSelf().children('a').removeClass('active');
http://jsfiddle.net/mblase75/BSKrG/2/
It's not working on the upper ones because you're assigning the same id to the divs. You should probably use the class attribute instead:
<div class="step2"><a>Damn</a></div>
<div class="step2"><a>Damn</a></div>
<div class="step2"><a>Damn</a></div>
After making the above changes, you should be able to do this:
$(".step2 a").text("Hello World!");
maybe this:
<div class="step">
<div id="step2"><a>Damn</a>
<a>Damn</a>
<a>Damn</a></div>
</div>
<div class="step">
<div id="step2"><a>Damn</a>
<a>Damn</a>
<a>Damn</a></div>
</div>
Using radio inputs you can create this effect without any JS at all, which degrades gracefully from its intended appearance (a red backgrounded "damn") to damn with radios next to it (sending the same information).
ironically, this example at JSfiddle: http://jsfiddle.net/YvQdj/
My memory is a bit fuzzy, but I'm pretty sure this doesn't work in older versions of IE without some finagling.
